ProcessWire is an award winning Open Source Content Management System(CMS) and Content Management Framework written in PHP. ProcessWire has been developed by Ryan Cramer since 2003. From 2003 to 2007 it was developed under the name Dictator CMS. From 2007–2010 it was developed as ProcessWire 1.x, and from 2010 to now, it has been developed as ProcessWire 2.x.

In this tutorial let us build a basic website using ProcessWire On CentOS 6.4. This how-to was tested on CentOS 6.4, although it will work on many RPM based distro’s. My test box hostname and IP address are and


Your server should have installed with following prerequisites. For more details about the software requirements visit this page.

First you have to install and configure LAMP server. Visit any one of the following links to setup LAMP server.

- Install LAMP (Apache, MariaDB, PHP) Server On CentOS 6.4.

- Install LAMP (Apache, MySQL, PHP) Server On CentOS 6.4.

Now install the following prerequisites too.

# yum install php-mcrypt php-pdo php-cli php-mysql php-gd php-xml libtool-ltdl mhash mcrypt -y

Create Database and User for ProcessWire

For instance, here i am going to create a database called “processdb” and database user called “processuser” with password “centos” for ProcessWire. You can define database and user as per your liking.

# mysql -u root -p
Enter password: 
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 3
Server version: 5.5.31-MariaDB MariaDB Server

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> create database processdb;
Query OK, 1 row affected (0.02 sec)

MariaDB [(none)]> GRANT ALL ON processdb.* TO processuser@localhost IDENTIFIED BY 'centos';
Query OK, 0 rows affected (0.01 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> exit

Firewall and SELinux Settings

Allow the apache default port “80″ through iptables/router. Edit file /etc/sysconfig/iptables,

# vi /etc/sysconfig/iptables

Add the following lines.

-A INPUT -p udp -m state --state NEW --dport 80 -j ACCEPT 
-A INPUT -p tcp -m state --state NEW --dport 80 -j ACCEPT

Now restart the iptables service.

# /etc/init.d/iptables restart

I don’t want to mess up with SELinux, so here i disabled it.

Edit file /etc/selinux/config,

# vi /etc/selinux/config

Set the SELINUX value as “disabled”.


Restart the system to take effect the saved changes.

Getting ProcessWire

Download the latest version here. I downloaded and saved it in my current directory.

Extract it using command:

# unzip

Move the extracted files to apache root folder.

# cp -fr ProcessWire-master/. /var/www/html/

Change to the /var/www/html/ directory. Rename the folder “site-default” to “site” and set read/write permissions for the following files/folders as shown below.

# cd /var/www/html/
# mv site-default/ site/
# chmod -R 777 site/assets/
# chmod -R 777 site/config.php

Rename the file “.htaccess.txt” to “.htaccess” in the processwire directory.

# mv htaccess.txt .htaccess
