In this post, we will go over how to perform a manual installation of latest Drupal 7.22 version on RHEL, CentOS and Fedora using LAMP setup.

What is LAMP?

LAMP stack is an open source web development software used to run web application. Wherein Linux is an Operating system, Apache is a Web Server, MySQL is a database and PHP is an object-oriented programming language. Please follow below link to install LAMP stack.

  1. Setup LAMP (Linux, Apache, MySQL, PHP) on RHEL, CentOS & Fedora

Drupal Requirement:

  1. Apache 2.x (Recommended)
  2. PHP 5.2.5 or higher (5.3 recommended)
  3. MySQL 5.0.15 or higher with PHP Data Objects (PDO)

In this post, I have used hostname as “drupal.tecmint.com” and IP address is “192.168.50.2“. These settings may differ at your environment, so please make changes as appropriate.

Installing Drupal 7.22 on RHEL, CentOS & Fedora

This installation method guide you how to install latest Drupal 7.22 using LAMP setup on RHEL, CentOS and Fedora.

Step 1: Download Drupal 7.22

Navigate and go to the directory from where we’ll be serving Drupal site. By default in most of *nix, server’s document root will be “/var/www/html“. Download Drupal with any download utility. Here, I’ll be using wget command.

[root@tecmint www]# wget http://ftp.drupal.org/files/projects/drupal-7.22.tar.gz

Step 2: Extract Compressed Drupal

Extract Drupal package which will create drupal-7.22 directory. After successfully extract, remove compressed version of Drupal.

[root@tecmint www]# tar -zxvf drupal-7.22.tar.gz

Remove source file and change ownership of directory with user and group Apache recursively with below command.

[root@tecmint drupal]# chown -R apache:apache /var/www/drupal

Step 3: Apache Configuration

Open Apache configuration file with editor.

[root@tecmint ~]# vi /etc/httpd/conf/httpd.conf

Search directive as below and change it appropriate.

ServerAdmin admin@tecmint.com

ServerName drupal.tecmint.com:80

Step 4: Restart httpd (Apache) Service

Restart Apache service.

[root@tecmint ~]# service httpd restart

To make httpd service started automatically in next boot with below command.

[root@tecmint ~]# chkconfig --level 35 httpd on

Verify your httpd is running and listening request on port 80

[root@tecmint ~]# netstat -antp | grep httpd

tcp     0      0 :::80            :::*          LISTEN 1705/httpd

Step 5: Create the settings.php file

Make a copy of sample configuration file which resides under Drupal directory ‘sites/default/default.settings.php’. Copy default file re-name it be ‘settings.php‘.

[root@tecmint drupal-7.22]# cp sites/default/default.settings.php sites/default/settings.php

Cautions: Don’t delete or rename default ‘default.settings.php‘ file as Drupal installer requires both files.

Now make a “settings.php” file and “default” directory writable by installer.

[root@tecmint drupal-7.22]# chmod a+w sites/default/settings.php
[root@tecmint drupal-7.22]# chmod a+w sites/default/

Note: Do not forget to change permissions back after you have run the installation script. Permissions should be as.

[root@tecmint drupal-7.22]# chmod 644 settings.php
[root@tecmint drupal-7.22]# chmod 755 ../default

Step 6: Create the MySQL Database

Set root password for MySQL login and creating database using following commands.

[root@tuxbox ~]# mysqladmin -u root password 'redhat'

Login with root credential in MySQL.

[root@tecmint ~]# mysql -u root -p

Create database called “drupal” in MySQL.

mysql> create database drupal;
Query OK, 1 row affected (0.05 sec)

Grant privileges on “drupal” database for “drupal” user in MySQL.

mysql> grant all on drupal.* to drupal@'localhost' identified by 'redhat';
Query OK, 0 rows affected (0.22 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

Restart MySQL Service.

[root@tecmint ~]# service mysqld status
[root@tecmint ~]# service mysqld restart
[root@tecmint ~]#chkconfig --level 35 mysqld on

Step 7: Iptables (Firewall) Configuration

Please open port 80 on firewall or disable iptables.

[root@tecmint html]# iptables -A INPUT -p tcp --dport 80 -j ACCEPT
[root@tecmint html]# service iptables save
[root@tecmint html]# service iptables restart

    Requirements problem

    Web server Apache/2.2.15 (CentOS)
    OK PHP 5.3.3
    OK PHP register globals Disabled
    Error PHP extensions Disabled

    Drupal requires you to enable the PHP extensions in the following list (see the system requirements page for more information):

    dom
    gd
    pdo

    Error Database support Disabled

    Your web server does not appear to support PDO (PHP Data Objects). Ask your hosting provider if they support the native PDO extension. See the system requirements page for more information.

    OK PHP memory limit 128M

    Error File system

    The directory sites/default/files is not writable. An automated attempt to create this directory failed, possibly due to a permissions problem. To proceed with the installation, either create the directory and modify its permissions manually or ensure that the installer has the permissions to create it automatically. For more information, see INSTALL.txt or the online handbook.

    Warning Unicode library Standard PHP

    Operations on Unicode strings are emulated on a best-effort basis. Install the PHP mbstring extension for improved Unicode support.

    OK Settings file The ./sites/default/settings.php file exists.

    Error Settings file The settings file is not writable.

    The Drupal installer requires write permissions to ./sites/default/settings.php during the installation process. If you are unsure how to grant file permissions, consult the online handbook.

    Check the error messages and proceed with the installation.
