How to Install WordPress with Nginx in a Docker Container
================================================================================
Hi all, today we'll learn how to install WordPress running Nginx Web Server in a Docker Container. WordPress is an awesome free and open source Content Management System running thousands of websites throughout the globe. [Docker][1] is an Open Source project that provides an open platform to pack, ship and run any application as a lightweight container. It has no boundaries of Language support, Frameworks or packaging system and can be run anywhere, anytime from a small home computers to high-end servers. It makes them great building blocks for deploying and scaling web apps, databases, and back-end services without depending on a particular stack or provider.
Today, we'll deploy a docker container with the latest WordPress package with necessary prerequisites ie Nginx Web Server, PHP5, MariaDB Server, etc. Here are some short and sweet steps to successfully install a WordPress running Nginx in a Docker Container.
### 1. Installing Docker ###
Before we really start, we'll need to make sure that we have Docker installed in our Linux machine. Here, we are running CentOS 7 as host so, we'll be running yum manager to install docker using the below command.
# yum install docker
![Installing Docker](http://blog.linoxide.com/wp-content/uploads/2015/03/installing-docker.png)
# systemctl restart docker.service
### 2. Creating WordPress Dockerfile ###
We'll need to create a Dockerfile which will automate the installation of the wordpress and its necessary pre-requisites. This Dockerfile will be used to build the image of WordPress installation we created. This WordPress Dockerfile fetches a CentOS 7 image from the Docker Registry Hub and updates the system with the latest available packages. It then installs the necessary softwares like Nginx Web Server, PHP, MariaDB, Open SSH Server and more which are essential for the Docker Container to work. It then executes a script which will initialize the installation of WordPress out of the box.
# nano Dockerfile
Then, we'll need to add the following lines of configuration inside that Dockerfile.
FROM centos:centos7
MAINTAINER The CentOS Project <cloud-ops@centos.org>
RUN yum -y update; yum clean all
RUN yum -y install epel-release; yum clean all
RUN yum -y install mariadb mariadb-server mariadb-client nginx php-fpm php-cli php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-magickwand php-magpierss php-mbstring php-mcrypt php-mssql php-shout php-snmp php-soap php-tidy php-apc pwgen python-setuptools curl git tar; yum clean all
ADD ./start.sh /start.sh
ADD ./nginx-site.conf /nginx.conf
RUN mv /nginx.conf /etc/nginx/nginx.conf
RUN rm -rf /usr/share/nginx/html/*
RUN /usr/bin/easy_install supervisor
RUN /usr/bin/easy_install supervisor-stdout
ADD ./supervisord.conf /etc/supervisord.conf
RUN echo %sudo ALL=NOPASSWD: ALL >> /etc/sudoers
ADD http://wordpress.org/latest.tar.gz /wordpress.tar.gz
RUN tar xvzf /wordpress.tar.gz
RUN mv /wordpress/* /usr/share/nginx/html/.
RUN chown -R apache:apache /usr/share/nginx/
RUN chmod 755 /start.sh
RUN mkdir /var/run/sshd
EXPOSE 80
EXPOSE 22
CMD ["/bin/bash", "/start.sh"]
![Wordpress Dockerfile](http://blog.linoxide.com/wp-content/uploads/2015/03/Dockerfile-wordpress.png)
### 3. Creating Start script ###
After we create our Dockerfile, we'll need to create a script named start.sh which will run and configure our WordPress installation. It will create and configure database, passwords for wordpress. To create it, we'll need to open start.sh with our favorite text editor.
# nano start.sh
After opening start.sh, we'll need to add the following lines of configuration into it.
#!/bin/bash
__check() {
if [ -f /usr/share/nginx/html/wp-config.php ]; then
exit
fi
}
__create_user() {
# Create a user to SSH into as.
SSH_USERPASS=`pwgen -c -n -1 8`
useradd -G wheel user
echo user:$SSH_USERPASS | chpasswd
echo ssh user password: $SSH_USERPASS
}
__mysql_config() {
# Hack to get MySQL up and running... I need to look into it more.
yum -y erase mariadb mariadb-server
rm -rf /var/lib/mysql/ /etc/my.cnf
yum -y install mariadb mariadb-server
mysql_install_db
chown -R mysql:mysql /var/lib/mysql
/usr/bin/mysqld_safe &
sleep 10
}
__handle_passwords() {
# Here we generate random passwords (thank you pwgen!). The first two are for mysql users, the last batch for random keys in wp-config.php
WORDPRESS_DB="wordpress"
MYSQL_PASSWORD=`pwgen -c -n -1 12`
WORDPRESS_PASSWORD=`pwgen -c -n -1 12`
# This is so the passwords show up in logs.
echo mysql root password: $MYSQL_PASSWORD
echo wordpress password: $WORDPRESS_PASSWORD
echo $MYSQL_PASSWORD > /mysql-root-pw.txt
echo $WORDPRESS_PASSWORD > /wordpress-db-pw.txt
# There used to be a huge ugly line of sed and cat and pipe and stuff below,
# but thanks to @djfiander's thing at https://gist.github.com/djfiander/6141138
# there isn't now.
sed -e "s/database_name_here/$WORDPRESS_DB/
s/username_here/$WORDPRESS_DB/
s/password_here/$WORDPRESS_PASSWORD/
/'AUTH_KEY'/s/put your unique phrase here/`pwgen -c -n -1 65`/
/'SECURE_AUTH_KEY'/s/put your unique phrase here/`pwgen -c -n -1 65`/

}
__httpd_perms() {
chown apache:apache /usr/share/nginx/html/wp-config.php
}
__start_mysql() {
# systemctl start mysqld.service
mysqladmin -u root password $MYSQL_PASSWORD
mysql -uroot -p$MYSQL_PASSWORD -e "CREATE DATABASE wordpress; GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpress'@'localhost' IDENTIFIED BY '$WORDPRESS_PASSWORD'; FLUSH PRIVILEGES;"
killall mysqld
sleep 10
}
__run_supervisor() {
supervisord -n
}
# Call all functions
__check
__create_user
__mysql_config
__handle_passwords
__httpd_perms
__start_mysql
__run_supervisor
![Start Script](http://blog.linoxide.com/wp-content/uploads/2015/03/start-script.png)
After adding the above configuration, we'll need to save it and then exit.
### 4. Creating Configuration files ###
Now, we'll need to create configuration file for Nginx Web Server named nginx-site.conf .
# nano nginx-site.conf
Then, we'll add the following configuration to the config file.
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log;
#error_log /var/log/nginx/error.log notice;
#error_log /var/log/nginx/error.log info;
pid /run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
index index.html index.htm index.php;
# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include
# for more information.
include /etc/nginx/conf.d/*.conf;
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
root /usr/share/nginx/html;
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root /usr/share/nginx/html;
try_files $uri =404;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
}
![Nginx configuration](http://blog.linoxide.com/wp-content/uploads/2015/03/nginx-conf.png)
Now, we'll create supervisord.conf file and add the following lines as shown below.
# nano supervisord.conf
Then, add the following lines.
[unix_http_server]
file=/tmp/supervisor.sock ; (the path to the socket file)
[supervisord]
logfile=/tmp/supervisord.log ; (main log file;default $CWD/supervisord.log)
logfile_maxbytes=50MB ; (max main logfile bytes b4 rotation;default 50MB)
logfile_backups=10 ; (num of main logfile rotation backups;default 10)
loglevel=info ; (log level;default info; others: debug,warn,trace)
pidfile=/tmp/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
nodaemon=false ; (start in foreground if true;default false)
minfds=1024 ; (min. avail startup file descriptors;default 1024)
minprocs=200 ; (min. avail process descriptors;default 200)
; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[supervisorctl]
serverurl=unix:///tmp/supervisor.sock ; use a unix:// URL for a unix socket
[program:php-fpm]
command=/usr/sbin/php-fpm -c /etc/php/fpm
stdout_events_enabled=true
stderr_events_enabled=true
[program:php-fpm-log]
command=tail -f /var/log/php-fpm/php-fpm.log
stdout_events_enabled=true
stderr_events_enabled=true
[program:mysql]
command=/usr/bin/mysql --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib/mysql/plugin --user=mysql --log-error=/var/log/mysql/error.log --pid-file=/var/run/mysqld/mysqld.pid --socket=/var/run/mysqld/mysqld.sock --port=3306
stdout_events_enabled=true
stderr_events_enabled=true
[program:nginx]
command=/usr/sbin/nginx
stdout_events_enabled=true
stderr_events_enabled=true
[eventlistener:stdout]
command = supervisor_stdout
buffer_size = 100
events = PROCESS_LOG
result_handler = supervisor_stdout:event_handler
![Supervisord Configuration](http://blog.linoxide.com/wp-content/uploads/2015/03/supervisord.png)
After adding, we'll save and exit the file.
### 5. Building WordPress Container ###
Now, after done with creating configurations and scripts, we'll now finally use the Dockerfile to build our desired container with the latest WordPress CMS installed and configured according to the configuration. To do so, we'll run the following command in that directory.
# docker build --rm -t wordpress:centos7 .
![Building WordPress Container](http://blog.linoxide.com/wp-content/uploads/2015/03/building-wordpress-container.png)
### 6. Running WordPress Container ###
Now, to run our newly built container and open port 80 and 22 for Nginx Web Server and SSH access respectively, we'll run the following command.
# CID=$(docker run -d -p 80:80 wordpress:centos7)
![Run WordPress Docker](http://blog.linoxide.com/wp-content/uploads/2015/03/run-wordpress-docker.png)
To check the process and commands executed inside the container, we'll run the following command.
# echo "$(docker logs $CID )"
TO check if the port mapping is correct or not, run the following command.
# docker ps
![docker state](http://blog.linoxide.com/wp-content/uploads/2015/03/docker-state.png)
### 7. Web Interface ###
Finally if everything went accordingly, we'll be welcomed with WordPress when pointing the browser to http://ip-address/ or http://mywebsite.com/ .
![Wordpress Start](http://blog.linoxide.com/wp-content/uploads/2015/03/wordpress-start.png)
Now, we'll go step wise through the web interface and setup wordpress configuration, username and password for the WordPress Panel.
![Wordpress Welcome](http://blog.linoxide.com/wp-content/uploads/2015/03/wordpress-welcome.png)
Then, use the username and password entered above into the WordPress Login page.
![wordpress login](http://blog.linoxide.com/wp-content/uploads/2015/03/wordpress-login.png)
### Conclusion ###
We successfully built and run WordPress CMS under LEMP Stack running in CentOS 7 Operating System as the docker OS. Running WordPress inside a container makes a lot safe and secure to the host system from the security perspective. This article enables one to completely configure WordPress to run under Docker Container with Nginx Web Server. If you have any questions, suggestions, feedback please write them in the comment box below so that we can improve or update our contents. Thank you ! Enjoy :-)

Its Now Worth Try Installing PHP 7.0 on CentOS 7.x / Fedora 21
================================================================================
PHP is a well known general purpose, server side web scripting language. A vast majority of online websites are coded in this language. PHP is ever evolving, feature rich, easy to use and well organized scripting language. Currently PHP development team is working on next major release of PHP, named PHP 7. The current production PHP version is PHP 5.6, as you might already know that PHP 6 was aborted in the past, the supporters of PHP 7 did not want the next important PHP version to be confused with that branch that was killed long time in the past. So it has been decided to name the next major release of PHP as PHP 7 instead of 6. PHP 7.0 is supposed to be released in November this year.
Here are some of the prominent features in next major PHP release.
- In order to improve performance and memory footprints PHPNG feature has been added to this new release.
- JIT engine has been included to dynamically compile Zend opcodes into native machine code in order to achieve faster processing. This feature will allow subsequent calls to the same code so that it may run much faster.
- AST (Abstract Syntax Tree) is a newly added feature which will enhance support for php extensions and userland applications.
- Asynchronous Programming feature will add support for parallel tasks within the same request.
- New version will support for stand alone multi-threading web server so that it may handle many simultaneous requests using a single memory pool.
### Installing PHP 7 on Centos / Fedora ###
Lets see how we can install PHP7 on Centos 7 and Fedora 21. In order to install PHP7 we will need to first clone php-src repository. Once cloning process is complete, we will configure and compile it. Before we proceed, lets ensure that we do have followings installed on our Linux system otherwise PHP compile process will return errors and abort.
- Git
- autoconf
- gcc
- bison
All of the above metioned prerequisits can be installed using Yum package manager. The following single command should take care of this:
yum install git autoconf gcc bison
Ready to start PHP7 installation process ? Lets first create PHP7 directory and make it your working directory.
mkdir php7
cd php7
Now clone php-src repo, run following command on the terminal.
git clone https://git.php.net/repository/php-src.git
The process should complete in few min, here is sample output which you should see at the completion of this task.
[root@localhost php7]# git clone https://git.php.net/repository/php-src.git
Cloning into 'php-src'...
remote: Counting objects: 615064, done.
remote: Compressing objects: 100% (127800/127800), done.
remote: Total 615064 (delta 492063), reused 608718 (delta 485944)
Receiving objects: 100% (615064/615064), 152.32 MiB | 16.97 MiB/s, done.
Resolving deltas: 100% (492063/492063), done.
Lets configure and compile PHP7, run following commands on the terminal to start the configuration process:
cd php-src
./buildconf
Here is sample output for ./buildconf command.
[root@localhost php-src]# ./buildconf
buildconf: checking installation...
buildconf: autoconf version 2.69 (ok)
rebuilding aclocal.m4
rebuilding configure
rebuilding main/php_config.h.in
Proceed further with the configuration process using following command:
./configure \
--prefix=$HOME/php7/usr \
--with-config-file-path=$HOME/php7/usr/etc \
--enable-mbstring \
--enable-zip \
--enable-bcmath \
--enable-pcntl \
--enable-ftp \
--enable-exif \
--enable-calendar \
--enable-sysvmsg \
--enable-sysvsem \
--enable-sysvshm \
--enable-wddx \
--with-curl \
--with-mcrypt \
--with-iconv \
--with-gmp \
--with-pspell \
--with-gd \
--with-jpeg-dir=/usr \
--with-png-dir=/usr \
--with-zlib-dir=/usr \
--with-xpm-dir=/usr \
--with-freetype-dir=/usr \
--with-t1lib=/usr \
--enable-gd-native-ttf \
--enable-gd-jis-conv \
--with-openssl \
--with-mysql=/usr \
--with-pdo-mysql=/usr \
--with-gettext=/usr \
--with-zlib=/usr \
--with-bz2=/usr \
--with-recode=/usr \
--with-mysqli=/usr/bin/mysql_config
It will take a sweet amount to time, once completed, you should see output like this:
creating libtool
appending configuration tag "CXX" to libtool
Generating files
configure: creating ./config.status
creating main/internal_functions.c
creating main/internal_functions_cli.c

Build complete.
Don't forget to run 'make test'.
Thats all, its time to install PHP7 now, run following to install it.
make install
Sample output for successful install process should look like:
