In web development, Joomla stands as a robust and versatile Content Management System (CMS). It allows you to build dynamic websites and online applications with ease. This comprehensive guide will walk you through the process of installing and setting up Joomla 2.5.3 on CentOS 6\/RHEL 6. This version of Joomla, released on March 15, 2012, is a security release that addresses two high-priority issues: Privilege Escalation and Password Change.<\/p>\n
This tutorial is applicable not only to CentOS 6\/RHEL 6 but also to other versions such as CentOS 5.1, CentOS 5.2, CentOS 5.3, CentOS 5.4, CentOS 5.5, CentOS 5.6, CentOS 5.7, CentOS 6.x, and RHEL 5.x. Whether you’re a seasoned webmaster or a beginner, this guide will provide you with the knowledge you need to get your Joomla site up and running.<\/p>\n
The first step in installing Joomla 2.5.3 is to download the stable package from the official Joomla download sites. You can do this using the wget command. Here is the command you need to run:<\/p>\n
\r\nwget http:\/\/joomlacode.org\/gf\/download\/frsrelease\/16804\/73116\/Joomla_2.5.3-Stable-Full_Package.zip\r\n<\/pre>\nThis command will download the Joomla 2.5.3 Stable Package to your server.<\/p>\n
\r\n[root@rhel6 ~]# wget http:\/\/joomlacode.org\/gf\/download\/frsrelease\/16804\/73116\/Joomla_2.5.3-Stable-Full_Package.zip\r\n--2012-03-24 03:59:13-- http:\/\/joomlacode.org\/gf\/download\/frsrelease\/16804\/73116\/Joomla_2.5.3-Stable-Full_Package.zip\r\nResolving joomlacode.org... 206.123.111.164\r\nConnecting to joomlacode.org|206.123.111.164|:80... connected.\r\nHTTP request sent, awaiting response... 302 Found\r\nLocation: http:\/\/downloads.joomlacode.org\/frsrelease\/7\/3\/1\/73116\/Joomla_2.5.3-Stable-Full_Package.zip [following]\r\n--2012-03-24 03:59:14-- http:\/\/downloads.joomlacode.org\/frsrelease\/7\/3\/1\/73116\/Joomla_2.5.3-Stable-Full_Package.zip\r\nResolving downloads.joomlacode.org... 206.123.111.167\r\nConnecting to downloads.joomlacode.org|206.123.111.167|:80... connected.\r\nHTTP request sent, awaiting response... 200 OK\r\nLength: 7984960 (7.6M) [application\/zip]\r\nSaving to: \u00e2Joomla_2.5.3-Stable-Full_Package.zip\r\n\r\n100%[==========================================================>] 7,984,960 55.7K\/s in 2m 41s\r\n\r\n2012-03-24 04:01:55 (48.5 KB\/s) - Joomla_2.5.3-Stable-Full_Package.zip\r\n<\/pre>\nStep 2: Unzip the Package<\/h2>\n
Once the download is complete, you need to unzip the package into your web server’s document root. Here is the command to do that:<\/p>\n
\r\nunzip Joomla_2.5.3-Stable-Full_Package.zip -d \/var\/www\/html\/joomla253\r\n<\/pre>\nThis command will extract all the files from the Joomla package into a directory named joomla253 in your web server’s document root.<\/p>\n
Step 3: Create a Database for Joomla 2.5.3<\/h2>\n
Joomla needs a database to store all its data. Therefore, the next step is to create a database for Joomla 2.5.3. Here are the commands to do that:<\/p>\n
[root@rhel6 ~]# mysql -u root -p\r\nEnter password:\r\nWelcome to the MySQL monitor. Commands end with ; or \\g.\r\nYour MySQL connection id is 2\r\nServer version: 5.1.47 Source distribution\r\n\r\nCopyright (c) 2000, 2010, Oracle and\/or its affiliates. All rights reserved.\r\nThis software comes with ABSOLUTELY NO WARRANTY. This is free software,\r\nand you are welcome to modify and redistribute it under the GPL v2 license\r\n\r\nType 'help;' or '\\h' for help. Type '\\c' to clear the current input statement.\r\n\r\nmysql> create database joomla253db;\r\nQuery OK, 1 row affected (0.00 sec)\r\n\r\nmysql> CREATE USER 'joomla253user'@'localhost' IDENTIFIED BY 'joomla253password';\r\nQuery OK, 0 rows affected (0.01 sec)\r\n\r\nmysql> GRANT ALL PRIVILEGES ON joomla253db.* to joomla253user@localhost;\r\nQuery OK, 0 rows affected (0.00 sec)\r\n\r\nmysql> SHOW GRANTS FOR 'joomla253user'@'localhost';\r\n+----------------------------------------------------------------------------------------------------------------------+\r\n| Grants for joomla253user@localhost |\r\n+----------------------------------------------------------------------------------------------------------------------+\r\n| GRANT USAGE ON *.* TO 'joomla253user'@'localhost' IDENTIFIED BY PASSWORD '*F421F24167FCE0B4DAE4130DFB268C7897CF0C3D' |\r\n| GRANT ALL PRIVILEGES ON `joomla253db`.* TO 'joomla253user'@'localhost' |\r\n+----------------------------------------------------------------------------------------------------------------------+\r\n2 rows in set (0.01 sec)\r\n\r\nmysql> exit\r\nBye<\/pre>\nThese commands will create a new database named joomla253db, create a new user named joomla253user with the password joomla253password, grant all privileges on the joomla253db database to the joomla253user, and then exit the MySQL shell.<\/p>\n
Step 4: Copy and AllowWritable to configuration.php<\/h2>\n
Next, you need to copy the sample configuration file and make it writable. Here are the commands to do that:<\/p>\n
\r\ncp \/var\/www\/html\/joomla253\/installation\/configuration.php-dist \/var\/www\/html\/joomla253\/configuration.php\r\nchmod 777 \/var\/www\/html\/joomla253\/configuration.php\r\n<\/pre>\nThese commands will copy the sample configuration file to the main Joomla directory and then change the permissions of the configuration file to make it writable.<\/p>\n
Step 5: Turn Off Output Buffering on PHP<\/h2>\n
