在 CentOS 7 CPanel 服务器上安装 MariaDB 10
|
||
================================================================================
|
||
|
||
MariaDB 是一个增强版的、开源的 MySQL 替代品。它主要由 MariaDB 社区在维护，采用 GPL v2 授权许可。软件的安全性是 MariaDB 开发者的主要焦点。他们保持为 MariaDB 的每个版本发布安全补丁。当有任何安全问题被发现时，开发者会尽快修复并推出 MariaDB 的新版本。
|
||
|
||
### MariaDB 的优势 ###
|
||
|
||
- 完全开源
|
||
- 快速且透明的安全版本
|
||
- 与 MySQL 高度兼容
|
||
- 性能更好
|
||
- 比 MySQL 的存储引擎多
|
||
|
||
在这篇文章中，我将谈论关于如何在 CentOS7 CPanel 服务器上升级 MySQL5.5 到最新的 MariaDB 。在安装前先完成以下步骤。
|
||
|
||
### 先决条件: ###
|
||
|
||
#### 1. 停止当前 MySQL 服务 ####
|
||
|
||
root@server1 [/var/# mysql
|
||
Welcome to the MySQL monitor. Commands end with ; or \g.
|
||
Your MySQL connection id is 5859
|
||
Server version: 5.5.47-cll MySQL Community Server (GPL)
|
||
|
||

|
||

||

||
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
|
||
|
||
root@server1 [~]# systemctl stop mysql
|
||
root@server1 [~]# systemctl status mysql
|
||
● mysql.service - LSB: start and stop MySQL
|
||
Loaded: loaded (/etc/rc.d/init.d/mysql)
|
||
Active: failed (Result: exit-code) since Sun 2016-01-31 10:00:02 UTC; 1min 31s ago
|
||
Docs: man:systemd-sysv-generator(8)
|
||
Main PID: 23430 (code=exited, status=203/EXEC)
|
||
|
||
Jan 31 10:00:02 server1.centos7-test.com systemd[1]: Started MySQL Server.
|
||
Jan 31 10:00:02 server1.centos7-test.com systemd[1]: Starting MySQL Server...
|
||
Jan 31 10:00:02 server1.centos7-test.com systemd[1]: mysql.service: main process exited, code=exited, status=203/EXEC
|
||
Jan 31 10:00:02 server1.centos7-test.com systemd[1]: Unit mysql.service entered failed state.
|
||
Jan 31 10:00:02 server1.centos7-test.com systemd[1]: mysql.service failed.
|
||
|
||
#### 2. 在升级之前将所有配置文件和数据库转移 ####
|
||
|
||
转移数据库的存储路径和 MySQL 的配置文件
|
||
|
||
root@server1 [~]# cp -Rf /var/lib/mysql /var/lib/mysql-old
|
||
|
||
root@server1 [/var/lib/mysql]# cat /etc/my.cnf
|
||
[mysqld]
|
||
default-storage-engine=MyISAM
|
||
innodb_file_per_table=1
|
||
max_allowed_packet=268435456
|
||
open_files_limit=10000
|
||
|
||
root@server1 [~]#mv /etc/my.cnf /etc/my.cnf-old
|
||
|
||
#### 3. 从服务器上删除和卸载 MySQL 所有的 RPM 包 ####
|
||
|
||
运行以下命令来禁用 MySQL RPM 的目标（target）。通过运行此命令，cPanel 将不再处理 MySQL 的更新，并在系统上将这些 RPM 版本标记为已卸载。
|
||
|
||
/scripts/update_local_rpm_versions --edit target_settings.MySQL50 uninstalled
|
||
/scripts/update_local_rpm_versions --edit target_settings.MySQL51 uninstalled
|
||
/scripts/update_local_rpm_versions --edit target_settings.MySQL55 uninstalled
|
||
/scripts/update_local_rpm_versions --edit target_settings.MySQL56 uninstalled
|
||
|
||
现在运行以下命令：
|
||
|
||
/scripts/check_cpanel_rpms --fix --targets=MySQL50,MySQL51,MySQL55,MySQL56
|
||
|
||
移除服务器上所有已有的 MySQL RPM 来为 MariaDB 的安装清理环境。请看下面的输出：
|
||
|
||
root@server1 [/var/lib/mysql]# /scripts/check_cpanel_rpms --fix --targets=MySQL50,MySQL51,MySQL55,MySQL56
|
||
[2016-01-31 09:53:59 +0000]
|
||
[2016-01-31 09:53:59 +0000] Problems were detected with cPanel-provided files which are RPM controlled.
|
||
[2016-01-31 09:53:59 +0000] If you did not make these changes intentionally, you can correct them by running:
|
||
[2016-01-31 09:53:59 +0000]
|
||
[2016-01-31 09:53:59 +0000] > /usr/local/cpanel/scripts/check_cpanel_rpms --fix
|
||
[2016-01-31 09:53:59 +0000]
|
||
[2016-01-31 09:53:59 +0000] The following RPMs are unneeded on your system and should be uninstalled:
|
||
[2016-01-31 09:53:59 +0000] MySQL55-client-5.5.47-1.cp1148
|
||
[2016-01-31 09:53:59 +0000] MySQL55-devel-5.5.47-1.cp1148
|
||
[2016-01-31 09:53:59 +0000] MySQL55-server-5.5.47-1.cp1148
|
||
[2016-01-31 09:53:59 +0000] MySQL55-shared-5.5.47-1.cp1148
|
||
[2016-01-31 09:53:59 +0000] MySQL55-test-5.5.47-1.cp1148
|
||
[2016-01-31 09:53:59 +0000] compat-MySQL50-shared-5.0.96-4.cp1136
|
||
[2016-01-31 09:53:59 +0000] compat-MySQL51-shared-5.1.73-1.cp1150
|
||
[2016-01-31 09:53:59 +0000] Removing 0 broken rpms:
|
||
[2016-01-31 09:53:59 +0000] rpm: no packages given for erase
|
||
[2016-01-31 09:53:59 +0000] No new RPMS needed for install
|
||
[2016-01-31 09:53:59 +0000] Disabling service monitoring.
|
||
[2016-01-31 09:54:01 +0000] Uninstalling unneeded rpms: MySQL55-test MySQL55-server MySQL55-client compat-MySQL51-shared compat-MySQL50-shared MySQL55-shared MySQL55-devel
|
||
[2016-01-31 09:54:04 +0000] Removed symlink /etc/systemd/system/multi-user.target.wants/mysql.service.
|
||
[2016-01-31 09:54:04 +0000] Restoring service monitoring.
|
||
|
||
通过这些步骤，我们已经卸载了现有的 MySQL RPM，并做了标记来防止 MySQL的更新，服务器的环境已经清理，然后准备安装 MariaDB。
|
||
|
||
开始安装吧，我们需要根据 CentOS 和 MariaDB 的版本为 MariaDB 创建一个 yum 软件库。下面是我的做法！
|
||
|
||
### 安装步骤： ###
|
||
|
||
#### 第1步：创建 YUM 软件库。####
|
||
|
||
root@server1 [~]# vim /etc/yum.repos.d/MariaDB.repo
|
||
[mariadb]
|
||
name = MariaDB
|
||
baseurl = http://yum.mariadb.org/10.0/centos7-amd64/
|
||
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
|
||
gpgcheck=1
|
||
root@server1 [/etc/yum.repos.d]# cat /etc/yum.repos.d/MariaDB.repo
|
||
[mariadb]
|
||
name = MariaDB
|
||
baseurl = http://yum.mariadb.org/10.0/centos7-amd64/
|
||
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
|
||
gpgcheck=1
|
||
|
||
#### 第2步：打开 /etc/yum.conf 并修改如下行： ####
|
||
|
||
**删除这一行：**
|
||
|
||
exclude=courier* dovecot* exim* filesystem httpd* mod_ssl* mydns* mysql* nsd* php* proftpd* pure-ftpd* spamassassin* squirrelmail*
|
||
|
||
**替换为：**
|
||
|
||
exclude=courier* dovecot* exim* filesystem httpd* mod_ssl* mydns* nsd* proftpd* pure-ftpd* spamassassin* squirrelmail*
|
||
|
||
**重要**
|
||
|
||
需要确保我们已经从 exclude 列表中移除了 MySQL 和 PHP。
|
||
|
||
#### 第3步：运行以下命令来安装 MariaDB 和相关的包。 ####
|
||
|
||
root@server1 [~]#yum install MariaDB-server MariaDB-client MariaDB-devel php-mysql
|
||
|

|
||
#### 第4步：重新启动，并确保 MySQL 服务已启动。####
|
||
|
||
root@server1 [~]# systemctl start mysql
|
||
root@server1 [~]#
|
||
root@server1 [~]#
|
||
root@server1 [~]# systemctl status mysql
|
||

|
||
|
||
#### 第5步：运行 mysql_upgrade 命令。 ####
|
||
|
||
它将检查所有数据库中的所有表与当前安装的版本是否兼容，并在必要时会更新系统表，以赋予当前版本新增加的权限或能力。
|
||
|
||
|
||
root@server1 [~]# mysql_upgrade

#### 第6步：再次重新启动 MySQL 的服务，以确保一切都运行完好。 ####
|
||
|
||
root@server1 [~]# systemctl restart mysql
|
||
root@server1 [~]#
|
||
root@server1 [~]# systemctl status mysql
|
||
● mysql.service - LSB: start and stop MySQL
|

|
||
Jan 31 10:04:11 server1.centos7-test.com systemd[1]: Started LSB: start and stop MySQL.
|
||
|
||
#### 第7步：运行 EasyApache，重建 Apache/PHP 以支持 MariaDB，并确保所有 PHP 的模块保持不变。####
|
||
|
||
root@server1 [~]#/scripts/easyapache --build
|
||
|
||
**重要**
|
||
|
||
如果你在安装 MariaDB 之后忘记重建 Apache/PHP，将会报如下库错误：
|
||
|
||
root@server1 [/etc/my.cnf.d]# php -v
|
||
php: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory
|
||
|
||
#### 第8步：现在验证安装的程序和数据库。 ####
|
||
|
||
root@server1 [/var/lib/mysql]# mysql
|
||
