WordPress on AWS EC2

1. Make a SSH connection

2. Setup a mySql 

mysql -u root -p
CREATE USER 'wordpress-user'@'localhost' IDENTIFIED BY 'your_strong_password';
CREATE DATABASE `wordpress-db`;
GRANT ALL PRIVILEGES ON `wordpress-db`.* TO "wordpress-user"@"localhost";
FLUSH PRIVILEGES;
exit

3. Prepare wordpress

wget https://wordpress.org/latest.tar.gz
tar -xzf latest.tar.gz
rm latest.tar.gz
cd wordpress
cp wp-config-sample.php wp-config.php

4. Edit wp-config.php

vim wp-config.php

define('DB_NAME', 'wordpress-db');
define('DB_USER', 'wordpress-user');
define('DB_PASSWORD', 'your_strong_password');

Add this line above where it says /* That's all, stop editing! Happy blogging. */.

define( 'WP_ALLOW_MULTISITE', true );
define( 'DISALLOW_FILE_EDIT', true );
define( 'WP_POST_REVISIONS', 3 );
define( 'COOKIE_DOMAIN', $_SERVER[ 'HTTP_HOST' ] );
define( 'FORCE_SSL_ADMIN', false );

Visit https://api.wordpress.org/secret-key/1.1/salt/ to randomly generate a set of key values that you can copy and paste into your wp-config.php file.

Example (don't use these!):

define( 'AUTH_KEY',         't`DK%X:>xy|e-Z(BXb/f(Ur`8#~UzUQG-^_Cs_GHs5U-&Wb?pgn^p8(2@}IcnCa|' );
define( 'SECURE_AUTH_KEY',  'D&ovlU#|CvJ##uNq}bel+^MFtT&.b9{UvR]g%ixsXhGlRJ7q!h}XWdEC[BOKXssj' );
define( 'LOGGED_IN_KEY',    'MGKi8Br(&{H*~&0s;{k0<S(O:+f#WM+q|npJ-+P;RDKT:~jrmgj#/-,[hOBk!ry^' );
define( 'NONCE_KEY',        'FIsAsXJKL5ZlQo)iD-pt??eUbdc{_Cn<4!d~yqz))&B D?AwK%)+)F2aNwI|siOe' );
define( 'AUTH_SALT',        '7T-!^i!0,w)L#JK@pc2{8XE[DenYI^BVf{L:jvF,hf}zBf883td6D;Vcy8,S)-&G' );
define( 'SECURE_AUTH_SALT', 'I6`V|mDZq21-J|ihb u^q0F }F_NUcy`l,=obGtq*p#Ybe4a31R,r=|n#=]@]c #' );
define( 'LOGGED_IN_SALT',   'w<$4c$Hmd%/*]`Oom>(hdXW|0M=X={we6;Mpvtg+V.o<$|#_}qG(GaVDEsn,~*4i' );
define( 'NONCE_SALT',       'a|#h{c5|P &xWs4IZ20c2&%4!c(/uG}W:mAvy<I44`jAbup]t=]V<`}.py(wTP%%' );

5. Move files to the root folder

sudo mv * /var/www/html
cd ..
rm -r wordpress

6. Fix file permissions

sudo chown -R apache:apache /var/www/html

9. Exit ssh

exit

10. Install the wordpress over http. Install the cloudflare & SSL Insecure Content Fixer plugins. Turn on https.

11. Switch on SSL for wp-admin

vim /var/www/html/wp-config.php

define( 'FORCE_SSL_ADMIN', true );

P.S. Your WordPress installation is automatically configured using the public DNS address for your EC2 instance. If you stop and restart the instance, the public DNS address changes (unless it is associated with an Elastic IP address) and your blog will not work anymore because it references resources at an address that no longer exists (or is assigned to another EC2 instance). A more detailed description of the problem and several possible solutions are outlined in http://codex.wordpress.org/Changing_The_Site_URL.
