My server info.

#######################################
Server IP 	: 10.66.100.15
Disk 		: 25 GB
RAM		: 1GB
vCPU 		: 2
Service 	: WordPress
Web 		: Apache
Database 	: Mariadb
Php 		: 8.0
#######################################

Step #01: Must be server update and upgrade.

root@wordpress:~# lsb_release -a
root@wordpress:~# apt-get update && apt-get upgrade -y

Install web service and database nariadb.

root@wordpress:~# apt-get install -y apache2 apache2-utils mariadb-server
root@wordpress:~# systemctl enable apache2
root@wordpress:~# systemctl start apache2
root@wordpress:~# systemctl enable mariadb
root@wordpress:~# systemctl start mariadb

Setup mysql root password.

root@wordpress:~# mysql_secure_installation

Note : Default root password is blank then setup root password.

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.

You already have your root account protected, so you can safely answer 'n'.

Switch to unix_socket authentication [Y/n] y
Enabled successfully!
Reloading privilege tables..
 ... Success!


You already have your root account protected, so you can safely answer 'n'.

Change the root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

Step #02: Install some package and php.

root@wordpress:~# add-apt-repository -y ppa:ondrej/php
root@wordpress:~# apt update
root@wordpress:~# apt-get install -y php8.0 php8.0-mysql libapache2-mod-php8.0 php8.0-cli php8.0-cgi php8.0-gd

Test php is working fine. Create one tech.php file.

root@wordpress:~# nano /var/www/html/tech.php

Insert below line into this file.

<?php
phpinfo(); //PHP code goes here
?>

Then browse your server ip address.

http://10.66.100.15/tech.php

Step #03: Download latest WordPress and setup permission.

root@wordpress:~# wget -c http://wordpress.org/latest.tar.gz
root@wordpress:~# tar -xzvf latest.tar.gz
root@wordpress:~# rsync -av wordpress/* /var/www/html/
root@wordpress:~# chmod -R 755 /var/www/html/
root@wordpress:~# chown -R www-data:www-data /var/www/html/
root@wordpress:~# rm -rf /var/www/html/index.html

Create database using mysql terminal.

root@wordpress:~# mysql -u root -p

Then run below command.

MariDB [(none)]> create database wp_db character set utf8 collate utf8_bin;
MariDB [(none)]> grant all privileges on wp_db.* TO 'wp_db_user'@'localhost' identified by 'wp_db_pass@123';
MariDB [(none)]> flush privileges;
MariDB [(none)]> \q

copy wp-config-sample.php file name as wp-config.php

root@wordpress:~# mv /var/www/html/wp-config-sample.php /var/www/html/wp-config.php

Open wp-config.php file using any editor

root@wordpress:~# vi /var/www/html/wp-config.php

Insert database info into this file wp-config.php

define('DB_NAME', 'wp_db');
define('DB_USER', 'wp_db_user');
define('DB_PASSWORD', 'wp_db_pass@123');
define('DB_HOST', 'localhost');
define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');

Then save and exit. Type press Esc type :wq then press Enter for save this config file.

Now restart some package.

root@wordpress:~# systemctl restart apache2.service
root@wordpress:~# systemctl restart mysql.service

Open default web config file then add your server ip address.

root@wordpress:~# nano /etc/apache2/sites-available/000-default.conf

as like below config.

<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
ServerName 10.66.100.15
<Directory /var/www/html/>
AllowOverride All
</Directory>

Now setup rewrite config and restart apache service.

root@wordpress:~# a2enmod rewrite
root@wordpress:~# service apache2 restart
root@wordpress:~# touch /var/www/html/.htaccess
root@wordpress:~# chown :www-data /var/www/html/.htaccess
root@wordpress:~# chmod 664 /var/www/html/.htaccess

Now setup rewrite config and restart apache service.

http://10.66.100.15/
