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 + + 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...

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.
