How to Install Bugzilla with Apache and SSL on FreeBSD 10.2
|
||||
================================================================================
|
||||
Bugzilla is open source web base application for bug tracker and testing tool, develop by mozilla project, and licensed under Mozilla Public License. It is used by high tech company like mozilla, redhat and gnome. Bugzilla was originally created by Terry Weissman in 1998. It written in perl, use MySQL as the database back-end. It is a server software designed to help you manage software development. Bugzilla has a lot of features, optimized database, excellent security, advanced search tool, integrated with email capabilities etc.
|
||||
|
||||
In this tutorial we will install bugzilla 5.0 with apache for the web server, and enable SSL for it. Then install mysql51 as the database system on freebsd 10.2.
|
||||
|
||||
#### Prerequisite ####
|
||||
|
||||
FreeBSD 10.2 - 64bit.
|
||||
Root privileges.
|
||||
|
||||
### Step 1 - Update System ###
|
||||
|
||||
Log in to the freebsd server with ssl login, and update the repository database :
|
||||
|
||||
sudo su
|
||||
freebsd-update fetch
|
||||
freebsd-update install
|
||||
|
||||
### Step 2 - Install and Configure Apache ###
|
||||
|
||||
In this step we will install apache from the freebsd repositories with pkg command. Then configure apache by editing file "httpd.conf" on apache24 directory, configure apache to use SSL, and CGI support.
|
||||
|
||||
Install apache with pkg command :
|
||||
|
||||
pkg install apache24
|
||||
|
||||
Go to the apache directory and edit the file "httpd.conf" with nanao editor :
|
||||
|
||||
cd /usr/local/etc/apache24
|
||||
nano -c httpd.conf
|
||||
|
||||
Uncomment the list line below :
|
||||
|
||||
#Line 70
|
||||
LoadModule authn_socache_module libexec/apache24/mod_authn_socache.so
|
||||
|
||||
#Line 89
|
||||
LoadModule socache_shmcb_module libexec/apache24/mod_socache_shmcb.so
|
||||
|
||||
# Line 117
|
||||
LoadModule expires_module libexec/apache24/mod_expires.so
|
||||
|
||||
#Line 141 to enabling SSL
|
||||
LoadModule ssl_module libexec/apache24/mod_ssl.so
|
||||
|
||||
# Line 162 for cgi support
|
||||
LoadModule cgi_module libexec/apache24/mod_cgi.so
|
||||
|
||||
# Line 174 to enable mod_rewrite
|
||||
LoadModule rewrite_module libexec/apache24/mod_rewrite.so
|
||||
|
||||
# Line 219 for the servername configuration
|
||||
ServerName 127.0.0.1:80
|
||||
|
||||
Save and exit.
|
||||
|
||||
Next, we need to install mod perl from freebsd repository, and then enable it :
|
||||
|
||||
pkg install ap24-mod_perl2
|
||||
|
||||
To enable mod_perl, edit httpd.conf and add to the "Loadmodule" line below :
|
||||
|
||||
nano -c httpd.conf
|
||||
|
||||
Add line below :
|
||||
|
||||
# Line 175
|
||||
LoadModule perl_module libexec/apache24/mod_perl.so
|
||||
|
||||
Save and exit.
|
||||
|
||||
And before start apache, add it to start at boot time with sysrc command :
|
||||
|
||||
sysrc apache24_enable=yes
|
||||
service apache24 start
|
||||
|
||||
### Step 3 - Install and Configure MySQL Database ###
|
||||
|
||||
We will use mysql51 for the database back-end, and it is support for perl module for mysql. Install mysql51 with pkg command below :
|
||||
|
||||
pkg install p5-DBD-mysql51 mysql51-server mysql51-client
|
||||
|
||||
Now we must add mysql to the boot time, and then start and configure the root password for mysql.
|
||||
|
||||
Run command below to do it all :
|
||||
|
||||
sysrc mysql_enable=yes
|
||||
service mysql-server start
|
||||
mysqladmin -u root password aqwe123
|
||||
|
||||
Note :
|
||||
|
||||
mysql password : aqwe123
|
||||
|
||||
|
||||
|
||||
Next, we will log in to the mysql shell with user root and password that we've configured above, then we will create new database and user for bugzilla installation.
|
||||
|
||||
Log in to the mysql shell with command below :
|
||||
|
||||
mysql -u root -p
|
||||
password: aqwe123
|
||||
|
||||
Add the database :
|
||||
|
||||
create database bugzilladb;
|
||||
create user bugzillauser@localhost identified by 'bugzillauser@';
|
||||
grant all privileges on bugzilladb.* to bugzillauser@localhost identified by 'bugzillauser@';
|
||||
flush privileges;
|
||||
\q
|
||||
|
||||
|
||||
|
||||
Database for bugzilla is created, database "bugzilladb" with user "bugzillauser" and password "bugzillauser@".
|
||||
|
||||
### Step 4 - Generate New SSL Certificate ###
|
||||
|
||||
Generate new self signed ssl certificate on directory "ssl" for bugzilla site.
|
||||
|
||||
Go to the apache24 directory and create new directory "ssl" on it :
|
||||
|
||||
cd /usr/local/etc/apache24/
|
||||
mkdir ssl; cd ssl
|
||||
|
||||
Next, generate the certificate file with openssl command, then change the permission of the certificate file :
|
||||
|
||||
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /usr/local/etc/apache24/ssl/bugzilla.key -out /usr/local/etc/apache24/ssl/bugzilla.crt
|
||||
chmod 600 *
|
||||
|
||||
### Step 5 - Configure Virtualhost ###
|
||||
|
||||
We will install bugzilla on directory "/usr/local/www/bugzilla", so we must create new virtualhost configuration for it.
|
||||
|
||||
Go to the apache directory and create new directory called "vhost" for virtualhost file :
|
||||
|
||||
cd /usr/local/etc/apache24/
|
||||
mkdir vhost; cd vhost
|
||||
|
||||
Now create new file "bugzilla.conf" for the virtualhost file :
|
||||
|
||||
nano -c bugzilla.conf
|
||||
|
||||
Paste configuration below :
|
||||
|
||||
<VirtualHost *:80>
|
||||
ServerName mybugzilla.me
|
||||
ServerAlias www.mybuzilla.me
|
||||
DocumentRoot /usr/local/www/bugzilla
|
||||
Redirect permanent / https://mybugzilla.me/
|
||||
</VirtualHost>
|
||||
|
||||
Listen 443
|
||||
<VirtualHost _default_:443>
|
||||
ServerName mybugzilla.me
|
||||
DocumentRoot /usr/local/www/bugzilla
|
||||
|
||||
ErrorLog "/var/log/mybugzilla.me-error_log"
|
||||
CustomLog "/var/log/mybugzilla.me-access_log" common
|
||||
|
||||
SSLEngine On
|
||||
SSLCertificateFile /usr/local/etc/apache24/ssl/bugzilla.crt
|
||||
SSLCertificateKeyFile /usr/local/etc/apache24/ssl/bugzilla.key
|
||||
|
||||
<Directory "/usr/local/www/bugzilla">
|
||||
AddHandler cgi-script .cgi
|
||||
Options +ExecCGI
|
||||
DirectoryIndex index.cgi index.html
|
||||
AllowOverride Limit FileInfo Indexes Options
|
||||
Require all granted
|
||||
</Directory>
|
||||
</VirtualHost>
|
||||
|
||||
Save and exit.
|
||||
|
||||
If all is done, create new directory for bugzilla installation and then enable the bugzilla virtualhost by adding the virtualhost configuration to httpd.conf file.
|
||||
|
||||
Run command below on "apache24" directory :
|
||||
|
||||
mkdir -p /usr/local/www/bugzilla
|
||||
cd /usr/local/etc/apache24/
|
||||
nano -c httpd.conf
|
||||
|
||||
In the end of the line, add configuration below :
|
||||
|
||||
Include etc/apache24/vhost/*.conf
|
||||
|
||||
Save and exit.
|
||||
|
||||
Now test the apache configuration with "apachectl" command and restart it :
|
||||
|
||||
apachectl configtest
|
||||
service apache24 restart
|
||||
|
||||
### Step 6 - Install Bugzilla ###
|
||||
|
||||
We can install bugzilla manually by downloading the source, or install it from freebsd repository. In this step we will install bugzilla from freebsd repository with pkg command :
|
||||
|
||||
pkg install bugzilla50
|
||||
|
||||
If it's done, go to the bugzilla installation directory and install all perl module that needed by bugzilla.
|
||||
|
||||
cd /usr/local/www/bugzilla
|
||||
./install-module --all
|
||||
|
||||
Wait it until all is finished, it is take the time.
|
||||
|
||||
Next, generate the configuration file "localconfig" by executing "checksetup.pl" file on bugzilla installation directory.
|
||||
|
||||
./checksetup.pl
|
||||
|
||||
You will see the error message about the database configuration, so edit the file "localconfig" with nano editor :
|
||||
|
||||
nano -c localconfig
|
||||
|
||||
Now add the database that was created on step 3.
|
||||
|
||||
#Line 57
|
||||
$db_name = 'bugzilladb';
|
||||
|
||||
#Line 60
|
||||
$db_user = 'bugzillauser';
|
||||
|
||||
#Line 67
|
||||
$db_pass = 'bugzillauser@';
|
||||
|
||||
Save and exit.
|
||||
|
||||
Then run "checksetup.pl" again :
|
||||
|
||||
./checksetup.pl
|
||||
|
||||
You will be prompt about mail and administrator account, fill all of it with your email, user and password.
|
||||
|
||||
|
||||
|
||||
In the last, we need to change the owner of the installation directory to user "www", then restart apache with service command :
|
||||
|
||||
cd /usr/local/www/
|
||||
chown -R www:www bugzilla
|
||||
service apache24 restart
|
||||
|
||||
Now Bugzilla is installed, you can see it by visiting mybugzilla.me and you will be redirect to the https connection.
|
||||
|
||||
Bugzilla home page.
|
||||
|
||||
|
||||
|
||||
Bugzilla admin panel.
|
||||
|
||||
|
||||
|
||||
### Conclusion ###
|
||||
|
||||
Bugzilla is web based application help you to manage the software development. It is written in perl and use MySQL as the database system. Bugzilla used by mozilla, redhat, gnome etc for help their software development. Bugzilla has a lot of features and easy to configure and install.

How to block network traffic by country on Linux
|
||||
================================================================================
|
||||
As a system admin who maintains production Linux servers, there are circumstances where you need to **selectively block or allow network traffic based on geographic locations**. For example, you are experiencing denial-of-service attacks mostly originating from IP addresses registered with a particular country. You want to block SSH logins from unknown foreign countries for security reasons. Your company has a distribution right to online videos, which requires it to legally stream to particular countries only. You need to prevent any local host from uploading documents to any non-US remote cloud storage due to geo-restriction company policies.

How to use KVM from the command line on Debian or Ubuntu
|
||||
================================================================================
|
||||
There are different ways to manage virtual machines (VMs) running on KVM hypervisor. For example, virt-manager is a popular GUI-based front-end for VM management. However, if you would like to use KVM on a headless server, GUI-based solutions will not be ideal. In fact, you can create and manage KVM VMs purely from the command line using kvm command-line wrapper script. Alternatively, you can use virsh which is an easier-to-use command-line user interface for managing guest VMs. Underneath virsh, it communicates wtih libvirtd service which can control several different hypervisors including KVM, Xen, QEMU, LXC and OpenVZ.

As a system administrator, you plan on using OpenSSH for Linux and automate your daily tasks such as transferring files or database dump file for the backup to another server. To achieve this goal, you need to log in automatically from the host A to host B. Login automatically mean you do not want to enter any password because you want to use ssh from a shell script.
|
||||
|
||||
In this article we’ll show you how to Setup SSH Login without Password on CentOS / RHEL. After automatic login has been configured, you can use it to move the file using SSH (Secure Shell) and secure copy (SCP).

|
||||
SSH is open source and the most trusted network protocol which is used to login to the remote server. It is used by system administrators to execute commands, also used to transfer files from one computer to another over a network using SCP protocol.
|
||||
|
||||
After you setup SSH login without password, you can get the following advantages :
|
||||
|
||||
a) Automate your daily task via scripts.
|
||||
b) Enhance security of your linux server. This is one of the recommended method to prevent a brute force attack on virtual private server (VPS), SSH keys are nearly impossible to decipher by brute force alone.
|
||||
|
||||
### What is ssh-keygen ###
|
||||
|
||||
ssh-keygen is a Unix utility that is used to generate, create, manage the public and private keys for ssh authentication. With the help of the ssh-keygen tool, a user can create passphrase keys for both SSH protocol version 1 and version 2. ssh-keygen creates RSA keys for SSH protocol version 1 and RSA or DSA keys for use by SSH protocol version 2.
|
||||
|
||||
### What is ssh-copy-id ###
|
||||
|
||||
ssh-copy-id is a script that copies the local-host’s public key to the remote-host’s authorized_keys file. ssh-copy-id also append the indicated identity file to that machine’s ~/.ssh/authorized_keys file and assigns proper permission to the remote-host’s home.
|
||||
|
||||
### SSH keys ###
|
||||
|
||||
SSH keys provide better and secure way of logging into a linux server with SSH. After you run ssh-keygen, you will generate public key and private key. You can place the public key on any server, and then unlock it by connecting to it with a client that already has the private key. When the two match up, the system unlocks without the need for a password.
|
||||
|
||||
### Setup SSH Login Without Password on CentOS and RHEL. ###
|
||||
|
||||
This steps tested on CentOS 5/6/7, RHEL 5/6/7 and Oracle Linux 6/7.
|
||||
|
||||
Node1 : 192.168.0.9
|
||||
Node2 : 192.168.l.10
|
||||
|
||||
#### Step One : ####
|
||||
|
||||
Test the connection and access from node1 to node2 :
|
||||
|
||||
[root@node1 ~]# ssh root@192.168.0.10
|
||||
The authenticity of host '192.168.0.10 (192.168.0.10)' can't be established.
|
||||
RSA key fingerprint is 6d:8f:63:9b:3b:63:e1:72:b3:06:a4:e4:f4:37:21:42.
|
||||
Are you sure you want to continue connecting (yes/no)? yes
|
||||
Warning: Permanently added '192.168.0.10' (RSA) to the list of known hosts.
|
||||
root@192.168.0.10's password:
|
||||
Last login: Thu Dec 10 22:04:55 2015 from 192.168.0.1
|
||||
[root@node2 ~]#
|
||||
|
||||
#### Step Two : ####
|
||||
|
||||
Generate public and private keys using ssh-key-gen. Please take note that you can increase security by protecting the private key with a passphrase.
|
||||
|
||||
[root@node1 ~]# ssh-keygen
|
||||
Generating public/private rsa key pair.
|
||||
Enter file in which to save the key (/root/.ssh/id_rsa):
|
||||
Enter passphrase (empty for no passphrase):
|
||||
Enter same passphrase again:
|
||||
Your identification has been saved in /root/.ssh/id_rsa.
|
||||
Your public key has been saved in /root/.ssh/id_rsa.pub.
|
||||
The key fingerprint is:
|
||||
b4:51:7e:1e:52:61:cd:fb:b2:98:4b:ad:a1:8b:31:6d root@node1.ehowstuff.local
|
||||
The key's randomart image is:
|
||||
+--[ RSA 2048]----+
|
||||
| . ++ |
|
||||
| o o o |
|
||||
| o o o . |
|
||||
| . o + .. |
|
||||
| S . . |
|
||||
| . .. .|
|
||||
| o E oo.o |
|
||||
| = ooo. |
|
||||
| . o.o. |
|
||||
+-----------------+
|
||||
|
||||
#### Step Three : ####
|
||||
|
||||
Copy or transfer the public key to remote-host using ssh-copy-id command. It will append the indicated identity file to ~/.ssh/authorized_keys on node2 :
|
||||
|
||||
[root@node1 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub 192.168.0.10
|
||||
root@192.168.0.10's password:
|
||||
Now try logging into the machine, with "ssh '192.168.0.10'", and check in:
|
||||
|
||||
.ssh/authorized_keys
|
||||
|
||||
to make sure we haven't added extra keys that you weren't expecting.
|
||||
|
||||
#### Step Four : ####
|
||||
|
||||
Try SSH login without Password to node2 :
|
||||
|
||||
[root@node1 ~]# ssh root@192.168.0.10

如何在FreeBSD 10.2上配置Apache和SSL并安装Bugzilla
|
||||
================================================================================
|
||||
Bugzilla是一款bug跟踪系统和测试工具，它基于web且开源，由mozilla计划开发并由Mozilla公共许可证授权。它经常被一些高科技公司如mozilla、红帽公司和gnome使用。Bugzilla起初由Terry Weissman在1998年创立，它用perl语言编写，用MySQL作为后端数据库。它是一款旨在帮助管理软件开发的服务器软件，它功能丰富、高优化度的数据库、卓越的安全性、高级的搜索工具、整合邮件功能等等。
|
||||
|
||||
在本教程中，我们将给web服务器安装bugzilla 5.0的apache并为它启用SSL，然后在freebsd 10.2上安装mysql 5.1来作为数据库系统。
|
||||
|
||||
#### 准备 ####
|
||||
|
||||
FreeBSD 10.2 - 64位
|
||||
Root权限
|
||||
|
||||
### 第一步 - 更新系统 ###
|
||||
|
||||
用ssl登录freebsd服务器，并更新库：
|
||||
|
||||
sudo su
|
||||
freebsd-update fetch
|
||||
freebsd-update install
|
||||
|
||||
### 第二步 - 安装并配置Apache ###
|
||||
|
||||
在这一步我们将从freebsd库中用pkg命令安装apache，然后在apache24目录下编辑"httpd.conf"文件，启用SSL和CGI支持。
|
||||
|
||||
用pkg命令安装apache：
|
||||
|
||||
pkg install apache24
|
||||
|
||||
进入apache目录并用nano编辑器编辑"httpd.conf"文件：
|
||||
|
||||
cd /usr/local/etc/apache24
|
||||
nano -c httpd.conf
|
||||
|
||||
反注释掉下面列出的行：
|
||||
|
||||
#第70行
|
||||
LoadModule authn_socache_module libexec/apache24/mod_authn_socache.so
|
||||
|
||||
#第89行
|
||||
LoadModule socache_shmcb_module libexec/apache24/mod_socache_shmcb.so
|
||||
|
||||
#第117行
|
||||
LoadModule expires_module libexec/apache24/mod_expires.so
|
||||
|
||||
#第141行，启用SSL
|
||||
LoadModule ssl_module libexec/apache24/mod_ssl.so
|
||||
|
||||
#第162行，支持cgi
|
||||
LoadModule cgi_module libexec/apache24/mod_cgi.so
|
||||
|
||||
#第174行，启用mod_rewrite
|
||||
LoadModule rewrite_module libexec/apache24/mod_rewrite.so
|
||||
|
||||
#第219行，服务器名配置
|
||||
ServerName 127.0.0.1:80
|
||||
|
||||
保存并退出。
|
||||
|
||||
接着，我们需要从freebsd库中安装mod perl，并启用它：
|
||||
|
||||
pkg install ap24-mod_perl2
|
||||
|
||||
启用mod_perl，编辑"httpd.conf"文件并添加"Loadmodule"行：
|
||||
|
||||
nano -c httpd.conf
|
||||
|
||||
添加该行：
|
||||
|
||||
#第175行
|
||||
LoadModule perl_module libexec/apache24/mod_perl.so
|
||||
|
||||
保存并退出。
|
||||
|
||||
在启用apache之前，用sysrc命令添加以下行来在引导的时候启动：
|
||||
|
||||
sysrc apache24_enable=yes
|
||||
service apache24 start
|
||||
|
||||
### 第三步 - 安装并配置MySQL数据库 ###
|
||||
|
||||
我们要用mysql 5.1来作为后端数据库并且支持perl模块。用pkg命令安装mysql 5.1：
|
||||
|
||||
pkg install p5-DBD-mysql51 mysql51-server mysql51-client
|
||||
|
||||
现在我们要在启动时添加mysql服务并启动，然后为mysql配置root密码。
|
||||
|
||||
运行以下命令来完成所有操作：
|
||||
|
||||
sysrc mysql_enable=yes
|
||||
service mysql-server start
|
||||
mysqladmin -u root password aqwe123
|
||||
|
||||
注意：
|
||||
|
||||
这里mysql密码为：aqwe123
|
||||
|
||||
|
||||
|
||||
以上步骤都完成之后，我们用root登录mysql shell，然后为bugzilla安装创建一个新的数据库和用户。
|
||||
|
||||
用以下命令登录mysql shell：
|
||||
|
||||
mysql -u root -p
|
||||
password: aqwe123
|
||||
|
||||
添加数据库：
|
||||
|
||||
create database bugzilladb;
|
||||
create user bugzillauser@localhost identified by 'bugzillauser@';
|
||||
grant all privileges on bugzilladb.* to bugzillauser@localhost identified by 'bugzillauser@';
|
||||
flush privileges;
|
||||
\q
|
||||
|
||||
|
||||
|
||||
bugzilla的数据库创建好了，名字为"bugzilladb"，用户名和密码分别为"bugzillauser"和"bugzillauser@"。
|
||||
|
||||
### 第四步 - 生成新的SSL证书 ###
|
||||
|
||||
在bugzilla站点的"ssl"目录里生成新的自签名SSL证书。
|
||||
|
||||
前往apache24目录并在此创建新目录"ssl"：
|
||||
|
||||
cd /usr/local/etc/apache24/
|
||||
mkdir ssl; cd ssl
|
||||
|
||||
接着，用openssl命令生成证书文件，然后更改其权限：
|
||||
|
||||
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /usr/local/etc/apache24/ssl/bugzilla.key -out /usr/local/etc/apache24/ssl/bugzilla.crt
|
||||
chmod 600 *
|
||||
|
||||
### 第五步 - 配置虚拟主机 ###
|
||||
|
||||
我们将在"/usr/local/www/bugzilla"目录里安装bugzilla，所以我们必须为它创建新的虚拟主机配置。
|
||||
|
||||
前往apache目录并为虚拟主机文件创建名为"vhost"的新目录：
|
||||
|
||||
cd /usr/local/etc/apache24/
|
||||
mkdir vhost; cd vhost
|
||||
|
||||
现在为虚拟主机文件创建新文件"bugzilla.conf"：
|
||||
|
||||
nano -c bugzilla.conf
|
||||
|
||||
将以下配置粘贴进去：
|
||||
|
||||
<VirtualHost *:80>
|
||||
ServerName mybugzilla.me
|
||||
ServerAlias www.mybuzilla.me
|
||||
DocumentRoot /usr/local/www/bugzilla
|
||||
Redirect permanent / https://mybugzilla.me/
|
||||
</VirtualHost>
|
||||
|
||||
Listen 443
|
||||
<VirtualHost _default_:443>
|
||||
ServerName mybugzilla.me
|
||||
DocumentRoot /usr/local/www/bugzilla
|
||||
|
||||
ErrorLog "/var/log/mybugzilla.me-error_log"
|
||||
CustomLog "/var/log/mybugzilla.me-access_log" common
|
||||
|
||||
SSLEngine On
|
||||
SSLCertificateFile /usr/local/etc/apache24/ssl/bugzilla.crt
|
||||
SSLCertificateKeyFile /usr/local/etc/apache24/ssl/bugzilla.key
|
||||
|
||||
<Directory "/usr/local/www/bugzilla">
|
||||
AddHandler cgi-script .cgi
|
||||
Options +ExecCGI
|
||||
DirectoryIndex index.cgi index.html
|
||||
AllowOverride Limit FileInfo Indexes Options
|
||||
Require all granted
|
||||
</Directory>
|
||||
</VirtualHost>
|
||||
|
||||
保存并退出。
|
||||
|
||||
上述都完成之后，为bugzilla安装创建新目录并通过添加虚拟主机配置至httpd.conf文件来启用bugzilla虚拟主机。
|
||||
|
||||
在"apache24"目录下运行以下命令：
|
||||
|
||||
mkdir -p /usr/local/www/bugzilla
|
||||
cd /usr/local/etc/apache24/
|
||||
nano -c httpd.conf
|
||||
|
||||
文末，添加以下配置：
|
||||
|
||||
Include etc/apache24/vhost/*.conf
|
||||
|
||||
保存并退出。
|
||||
|
||||
现在用"apachectl"命令测试一下apache的配置并重启它：
|
||||
|
||||
apachectl configtest
|
||||
service apache24 restart
|
||||
|
||||
### 第六步 - 安装Bugzilla ###
|
||||
|
||||
我们可以通过下载源来手动安装bugzilla了，或从freebsd库中安装也可以。在这一步中我们将用pkg命令从freebsd库中安装bugzilla：
|
||||
|
||||
pkg install bugzilla50
|
||||
|
||||
以上步骤都完成之后，前往bugzilla安装目录并安装所有bugzilla需要的perl模块。
|
||||
|
||||
cd /usr/local/www/bugzilla
|
||||
./install-module --all
|
||||
|
||||
要等到所有都完成，这需要点时间。
|
||||
|
||||
下一步，在bugzilla的安装目录中执行"checksetup.pl"文件来生成配置文件"localconfig"。
|
||||
|
||||
./checksetup.pl
|
||||
|
||||
你会看到一条关于数据库配置错误，你得用nano编辑器编辑一下"localconfig"文件：
|
||||
|
||||
nano -c localconfig
|
||||
|
||||
现在添加第三步创建的数据库。
|
||||
|
||||
#第五十七行
|
||||
$db_name = 'bugzilladb';
|
||||
|
||||
#第六十行
|
||||
$db_user = 'bugzillauser';
|
||||
|
||||
#第六十七行
|
||||
$db_pass = 'bugzillauser@';
|
||||
|
||||
保存并退出。
|
||||
|
||||
然后再次运行"checksetup.pl"：
|
||||
|
||||
./checksetup.pl
|
||||
|
||||
你会收到输入邮箱名和管理员账号的提示，你只要输入你得邮箱、用户名和密码就行了。
|
||||
|
||||
|
||||
|
||||
最后，我们需要把安装目录的属主改成"www"，然后用服务命令重启apache：
|
||||
|
||||
cd /usr/local/www/
|
||||
chown -R www:www bugzilla
|
||||
service apache24 restart
|
||||
|
||||
现在Bugzilla已经安装好了，你可以通过访问mybugzilla.me来查看，并且将会重定向到https连接。
|
||||
|
||||
Bugzilla首页：
|
||||
|
||||
|
||||
|
||||
Bugzilla admin面板：
|
||||
|
||||
|
||||
|
||||
### 结论 ###
|
||||
|
||||
Bugzilla是一个基于web并能帮助你管理软件开发的应用，它用perl开发并使用MySQL作为数据库系统。Bugzilla被mozilla,redhat,gnome等等公司用来帮助它们的软件开发工作。Bugzilla有很多功能并易于配置和安装。

如何在CentOS / RHEL上设置SSH免密码登录
|
||||
================================================================================
|
||||
|
||||
|
||||
作为系统管理员，你计划在Linux上使用OpenSSHell，完成日常工作的自动化，比如文件传输、备份数据库转储文件到另一台服务器。为实现该目标，你需要从主机A能自动登录到主机B。自动登录也就是说，要在shell脚本中使用ssh，而无需要输入任何密码。
|
||||
|
||||
本文会告诉你怎样在CentOS/RHEL上设置SSH免密码登录。自动登录配置好以后，你可以在它基础上用SSH (Secure Shell) 和secure copy (SCP)移动文件。
|
||||
|
||||
SSH是开源的，用于远程登录的最为可靠的网络协议。系统管理员用它来执行命令，以及通过SCP协议在网络上向另一台电脑传输文件。
|
||||
|
||||
通过配置SSH免密码登录，你可以享受到如下的便利：
|
||||
|
||||
a) 用脚本实现日常工作的自动化。
|
||||
b) 增强Linux服务器的安全性。这是防范虚拟专用服务器（VPS）遭受暴力破解攻击的一个推荐的方法，SSH 密钥单凭暴力破解是几乎不可攻破的。
|
||||
|
||||
### 什么是ssh-keygen ###
|
||||
|
||||
ssh-keygen是Unix实用工具包里的一个命令，用来生成、创建和管理SSH认证用的公私钥。通过ssh-keygen命令，用户可以创建支持SSH1和SSH2的密钥。ssh-keygen为SSH1创建RSA密钥，SSH2则可以是RSA或DSA。
|
||||
|
||||
### 什么是ssh-copy-id ###
|
||||
|
||||
ssh-copy-id是用来将本地公钥拷贝到远程authorized_keys文件的脚本命令，它还会将身份标识文件追加到远程机器的~/.ssh/authorized_keys文件中，并给远程主机的用户主目录适当的的权限
|
||||
|
||||
### SSH keys ###
|
||||
|
||||
SSH keys为登录Linux服务器提供了更好且安全的机制。运行ssh-keygen后，将会生成公私密钥对。你可以将公钥放置到任意服务器，从持有私钥的客户端连接到服务器的时，会用它来解锁。两者匹配时，系统无需密码就能解除锁定。
|
||||
|
||||
### 在CentOS和RHEL上设置免密码登录SSH ###
|
||||
|
||||
以下步骤在CentOS 5/6/7、RHEL 5/6/7和Oracle Linux 6/7上测试通过。
|
||||
|
||||
节点1 : 192.168.0.9
|
||||
节点2 : 192.168.l.10
|
||||
|
||||
#### 步骤1 : ####
|
||||
|
||||
测试节点1到节点2的连接和访问：
|
||||
|
||||
[root@node1 ~]# ssh root@192.168.0.10
|
||||
The authenticity of host '192.168.0.10 (192.168.0.10)' can't be established.
|
||||
RSA key fingerprint is 6d:8f:63:9b:3b:63:e1:72:b3:06:a4:e4:f4:37:21:42.
|
||||
Are you sure you want to continue connecting (yes/no)? yes
|
||||
Warning: Permanently added '192.168.0.10' (RSA) to the list of known hosts.
|
||||
root@192.168.0.10's password:
|
||||
Last login: Thu Dec 10 22:04:55 2015 from 192.168.0.1
|
||||
[root@node2 ~]#
|
||||
|
||||
#### 步骤二： ####
|
||||
|
||||
使用ssh-key-gen命令生成公钥和私钥，这里要注意的是可以对私钥进行加密保护以增强安全性。
|
||||
|
||||
[root@node1 ~]# ssh-keygen
|
||||
Generating public/private rsa key pair.
|
||||
Enter file in which to save the key (/root/.ssh/id_rsa):
|
||||
Enter passphrase (empty for no passphrase):
|
||||
Enter same passphrase again:
|
||||
Your identification has been saved in /root/.ssh/id_rsa.
|
||||
Your public key has been saved in /root/.ssh/id_rsa.pub.
|
||||
The key fingerprint is:
|
||||
b4:51:7e:1e:52:61:cd:fb:b2:98:4b:ad:a1:8b:31:6d root@node1.ehowstuff.local
|
||||
The key's randomart image is:
|
||||
+--[ RSA 2048]----+
|
||||
| . ++ |
|
||||
| o o o |
|
||||
| o o o . |
|
||||
| . o + .. |
|
||||
| S . . |
|
||||
| . .. .|
|
||||
| o E oo.o |
|
||||
| = ooo. |
|
||||
| . o.o. |
|
||||
+-----------------+
|
||||
|
||||
#### 步骤三： ####
|
||||
|
||||
用ssh-copy-di命令将公钥复制或上传到远程主机，并将身份标识文件追加到节点2的~/.ssh/authorized_keys中：
|
||||
|
||||
[root@node1 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub 192.168.0.10
|
||||
root@192.168.0.10's password:
|
||||
Now try logging into the machine, with "ssh '192.168.0.10'", and check in:
|
||||
|
||||
.ssh/authorized_keys
|
||||
|
||||
to make sure we haven't added extra keys that you weren't expecting.
|
||||
|
||||
#### 步骤四： ####
|
||||
|
||||
验证免密码SSH登录节点2：
|
||||
|
||||
[root@node1 ~]# ssh root@192.168.0.10
