Setting up Wordpress sites on EC2

Refer:

Step 1: Install the Apache Web Server

To install the Apache Web Server, type:
yum install httpd

Start the Apache Web Server:
service httpd start

To test your Web Server, open a browser and access your web site: http://ec2-50-17-14-16.compute-1.amazonaws.com (Use your actual public DNS name). You should see a standard Amazon place holder page.

Step 2: Install PHP

To install PHP, type:
yum install php php-mysql

Restart the Apache Web Server:
service httpd restart

Create a page to test your PHP installation:
cd /var/www/html
vi test.php

1. Type i to start the insert mode
2. Type <?php phpinfo() ?>
3. Type :wq to write the file and quit vi

Open a browser and access test.php to test your PHP installation: http://ec2-50-17-14-16.compute-1.amazonaws.com/test.php (Use your actual public DNS name).

Step 3: Install MySQL

To install MySQL, type:
yum install mysql-server

Start MySQL:
service mysqld start

Create your “blog” database:
mysqladmin -uroot create blog

Secure your database:
mysql_secure_Installation

Answer the wizard questions as follows:

1. Enter current password for root: Press return for none
2. Change Root Password: Y
3. New Password: Enter your new password
4. Remove anonymous user: Y
5. Disallow root login remotely: Y
6. Remove test database and access to it: Y
7. Reload privilege tables now: Y

Step 4: Install WordPress

To install WordPress, type:
cd /var/www/html
wget http://wordpress.org/latest.tar.gz
tar -xzvf latest.tar.gzcd

This will uncompress WordPress in its own “wordpress” directory. I like having WordPress in a separate directory, but would rather rename it to “blog”:
mv wordpress blog

Create the WordPress wp-config.php file:
cd blog
mv wp-config-sample.php wp-config.php
vi wp-config.php

1. Type i to start insert mode.
2. Modify the database connection parameters as follows:
   define(‘DB_NAME’, ‘blog’);
   define(‘DB_USER’, ‘root’);
   define(‘DB_PASSWORD’, ‘YOUR_PASSWORD’);
   define(‘DB_HOST’, ‘localhost’);
3. Type :wq to write the file and quit vi

Open a Browser and access your blog: http://ec2-50-17-14-16.compute-1.amazonaws.com/blog (Use your actual public DNS name). This should trigger the WordPress configuration process.
