WordPress Installation

WordPress is the most popular blogging system in use on the web. Here are the steps I followed to install it on my server.

After the initial setup of my new server, installation of a basic WordPress blog was simple. Create the database, configure Nginx, download, install and configure WordPress itself.

Database Creation

Create an account and a database for WordPress:

mysql -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 5340 to server version: 3.23.54
 
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
 
mysql> CREATE DATABASE illallangi_com;
Query OK, 1 row affected (0.00 sec)
 
mysql> GRANT ALL PRIVILEGES ON illallangi_com.* TO "illallangi_com"@"localhost"
    -> IDENTIFIED BY "password";
Query OK, 0 rows affected (0.00 sec)
  
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)

mysql> EXIT
Bye

Nginx Configuration

I created the /etc/nginx/conf.d/illallangi.com.conf file:

server {
    listen 80;
    server_name illallangi.com;
    client_max_body_size 64M;

    index index.php index.html;
    include /etc/nginx/default.d/*.conf;
    root  /var/www/illallangi.com/wordpress;

    location / {
        try_files $uri $uri/ /index.php?q=$request_uri;
    }
}

Restart the nginx service:

systemctl restart nginx

WordPress Install

Firstly I created a new directory for the site:

mkdir -p /var/www/illallangi.com

Then I downloaded and extracted the latest version of WordPress:

curl https://wordpress.org/wordpress-4.2.2.tar.gz | tar -zx --directory /var/www/illallangi.com/

WordPress Configuration

Create the wp-config.php file and configured it, stealing some code from a gist I found to do it on the command line (rather than editing the file in nano):

cp /var/www/illallangi.com/wordpress/wp-config-sample.php /var/www/illallangi.com/wordpress/wp-config.php
perl -pi -e "s/database_name_here/illallangi_com/g" /var/www/illallangi.com/wordpress/wp-config.php
perl -pi -e "s/username_here/illallangi_com/g" /var/www/illallangi.com/wordpress/wp-config.php
perl -pi -e "s/password_here/password/g" /var/www/illallangi.com/wordpress/wp-config.php
perl -i -pe'
    BEGIN {
      @chars = ("a" .. "z", "A" .. "Z", 0 .. 9);
      sub salt { join "", map $chars[ rand @chars ], 1 .. 64 }
    }
    s/put your unique phrase here/salt()/ge
  ' /var/www/illallangi.com/wordpress/wp-config.php

Themes and Plugins

All of these steps could have been completed through the WordPress web interface, but I like being able to do things on a command line, especially if I plan to script it later.

First I downloaded and installed my chosen theme, Tracks by Complete Themes:

curl -o /tmp/tracks.zip https://downloads.wordpress.org/theme/tracks.1.37.1.zip
unzip /tmp/tracks.zip -d /var/www/illallangi.com/wordpress/wp-content/themes

The default WordPress install includes two plugins, Akismet for comment spam protection and Hello Dolly as an example plugin. I remove unwanted plugins and themes to keep my install uncluttered. Manually upgrading the Akismet plugin to the latest version required a manual uninstall as well.

Removed old version of Akismet plugin and the Hello Dolly plugin:

rm -rf /var/www/illallangi.com/wordpress/wp-content/plugins/akismet
rm -f /var/www/illallangi.com/wordpress/wp-content/plugins/hello.php

Download and install akismet plugin:

curl -o /tmp/akismet.zip https://downloads.wordpress.org/plugin/akismet.3.1.3.zip
unzip /tmp/akismet.zip -d /var/www/illallangi.com/wordpress/wp-content/plugins

Download and install SyntaxHighlighter Evolved plugin:

curl -o /tmp/syntaxhighlighter.zip https://downloads.wordpress.org/plugin/syntaxhighlighter.zip
unzip /tmp/syntaxhighlighter.zip -d /var/www/illallangi.com/wordpress/wp-content/plugins

File and Directory Permissions

Set permissions on files:

find /var/www/illallangi.com/wordpress/ -type f -exec chmod 664 {} +
find /var/www/illallangi.com/wordpress/ -type d -exec chmod 775 {} +
chmod 660 /var/www/illallangi.com/wordpress/wp-config.php
chown -R apache.nobody /var/www/illallangi.com/wordpress

Next Steps

At this point the WordPress installation was complete. I pointed DNS for illallangi.com to the new server and browsed to it in Chrome. WordPress presented a final installation wizard, which created the initial database entries.

I could also have restored my database from backup at this point.
