This howto will outline how to install Apache httpd, MariaDB and multiple WordPress -stable and -development instances on your Centos (or other) Linux desktop so you can work anywhere, regardless of internet connection or not. These instructions can be easily adapted to any Linux system if you have enough specific knowledge of how your distro is setup.
- Note: these links may change in the future, if they become dead, please report it.
- Download WordPress -stable branch zip archive, do not use Yum to install WordPress.
- Root or sudo access to the Centos system
Doing the Work
Basic description of what will be done and what is expected.
- Edit
/etc/hostsas root: - Create web directories as root:
- Install httpd, MariaDB and PHP and configure them as root:
- Add Maria database container as root:
- Download WordPress into the Documentroot and configure
wp-config.phpas root: - As root, make sure MariaDB and httpd are started and and your web directories are all owned by the user/group your web server runs as (Warning: DO NOT DO THIS ON PRODUCTION SERVERS), in our case “apache”.
Next, the commands below will affect everything under:
/var/www/local_dev - Restart httpd and MariaDB
- Check the running status of mariadb and httpd:
- Check the VirtualHosts config in httpd:
- Check the /etc/hosts file:
- http://wiki.centos.org
- http://wordpress.org
- http://codex.wordpress.org
- http://wordpress.org/extend/plugins
- http://wordpress.org/extend/themes

Make sure it looks something like this: # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 yourhostname localhost.localdomain localhost ::1 yourhostname localhost6.localdomain6 localhost6 127.0.0.1 local_dev 127.0.0.1 wordpress1 127.0.0.1 wordpress2 |
cd /var/www/; mkdir -p local_dev wordpress1 wordpress2
yum install httpd mariadb-server mariadb-bench php56u
