Installing Dependencies

To install WordPress, you must required to have PHP and MySQL or mariaDB
Installing PHP

This is for Ubuntu/Debian Distro.

sudo apt update
sudo apt install php php-cli php-fpm php-json php-common php-mysql php-zip php-gd php-mbstring php-curl php-xml php-pear php-bcmath
If the above command returns package not found or similar error do this step else go to next step, then you need to add the PPA, you can add them by sudo add-apt-repository ppa:ondrej/php;sudo apt update and now repeat the above step
Now remove the apache2 server which is installed when installing PHP, by sudo apt purge apache2*
Check the PHP Version by running php -v

Installing MYSQL Database

If you don't have MYSQL installed refer this blog by digitalocean
Downloading Wordpress


Navigate to the required directory, where do you want to save wordpress. here I use /home/illuminate/php_sites
Download the latest Wordpress by wget https://wordpress.org/latest.tar.gz
extract the tar file by tar -xzvf latest.tar.gz
Delete the tar file after extraction completed
go to the wordpress/ by cd wordpress

Creating DB for Wordpress


If you have successfully installed mysql, create a seperate user and db for wordpress
Login to mysql by mysql -u adminusername -p and now Enter the password
replace the databasename with the database name you want.

CREATE DATABASE databasename;
use databasename;
CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
GRANT ALL ON *.* TO 'username'@'localhost';
flush privileges;

After the above steps successful, exit the mysql by pressing ctrl+d

Editing the Caddyfile


Now add the entry to serve Wordpress

example.com {
    root * /home/illuminate/php_sites/wordpress
    php_fastcgi unix//run/php/php8.0-fpm.sock
    file_server
    encode gzip

    @disallowed {
        path /xmlrpc.php
        path *.sql
        path /wp-content/uploads/*.php
    }

    rewrite @disallowed '/index.php'
}


Now relaod the caddy server.
and its done.

Configuring Wordpress


When you visit the domain configured in caddyfile, it will ask to configure if not configured.
Enter the database credentials as we created.
If it fails to write wp-config.php file, then copy the configuration from web
create a wp-config.php file inside the directory where wp-content, wp-admin, wp-content are present, for me its /home/illuminate/php_sites/wordpress
paste the contents copied into the file, save and begin the installation.
