Installing Wordpress on CentOS 5.x

This is not the famous 5 minute installation, but it comes close. It takes other minor items into account, like php53 and the APC accelerator cache. I'll follow up soon with some backup scripts, but here's a baseline installation guide.

At the time of this blog entry, WordPress was up to version 3.3.2

Assumptions:
Server has a clean install of CentOS 5.x and access to the internet.

1. Login as root or su

2. Install Webserver and Database and other prerequisites
yum install httpd* mysqld* gcc* pcre-devel

3. Install php 5.3

4. Install a php accelerator

5. Start services and configure to start on boot

chkconfig httpd on && service httpd start
chkconfig mysqld on && service mysqld start

6. Lock down mysql
/usr/bin/mysqladmin -u root password 'yourpasswordhere'
7. Create an empty wordpress database and account in Mysql
mysql -u root -p yourpasswordhere
At the mysql prompt:
CREATE DATABASE mydbname CHARSET 'utf8';
GRANT select,insert,update,delete,create,drop,index,alter
ON mydbname.*
TO mywpuser@localhost IDENTIFIED BY 'wpuserpassword';
flush privileges;
quit;

8. Download wordpress
cd /temp
wget http://wordpress.org/latest.zip
unzip latest.zip
cd wordpress
cp -r * /var/www/html/


9. Create a Wordpress data directory and assign permissions
cd /var/www/html/wp-content
mkdir uploads
mkdir cache
cd ../
chown –R apache:apache *

10. Copy default config file

cp wp-sample-config.php wp-config.php

11.    Edit config file
nano wp-config.php
Modify the following vars:
DB_NAME
The database name created in Step 7
DB_USER
The username created in Step 7
DB_PASSWORD
The password created in Step 7
DB_HOST
Localhost
(or specify remote host if applicable)

12. Open up a web browser to start WordPress config
http://my.server.ip/wp-admin/install.php

Press on..
