How to Install WordPress with Nginx on Rocky Linux 10 with SSL

Last week I was browsing the internet for the best WordPress setup and came across three kinds of setup LAMP (Linux, Apache, MySql and Php), LEMP (Linux, Nginx, MySql and Php) and WordPress with OpenLitespeed.

Being an IT guy I know that Nginx and OpenLitespeed are the fastest. So, I shortlisted WordPress with OpenLitespeed and LEMP setups. I thought to first try both and then finalize the one I will stick to.

Although, i will also share a tutorial on how to install WordPress with OpenLitespeed on Rocky Linux or on Ubuntu soon.

WordPress with OpenLitespeed

I quickly purchased a VPS from OVHCloud and tried setting up WordPress with OpenLitespeed. It worked well and I found out that QUIC and WordPress LiteSpeed cache plugin works together to provide the best performance WordPress setup. When I scanned my website on PageSpeed I was getting a score of 97 and 98 on Mobile and Desktop which was freaking awesome. But the worst part for me was QUIC credits. If the credits are over, you either have to pay for more credits or end up having a normal performing website.

WordPress with LEMP

Then I thought to try LEMP setup. I quickly reinstalled Rocky Linux 10 on my VPS and started configuring LEMP setup. As the setup completed, I was surprised that without doing much of the tuning, I managed to get PageSpeed score of 98 and 99 for Mobile and Desktop and the best part is that I don’t have to pay a single penny other than hosting to keep my WordPress setup highly stable and blazing fast.

So for me, LEMP stands as the best WordPress setup and here is the complete tutorial that you can follow to install yourself

Prerequisites

Point your DNS to your server’s IP
A VPS with Rocky Linux 10 Installed
A sudo user

Step 1 – Installing nano editor

Before we begin lets first install nano editor which will help us in editing the configuration file

sudo dnf update -y
sudo dnf install nano -y

Step 2 – Install Nginx

Now let’s install Nginx on our server and start its services. To install Nginx and start its services, run the given below commands one by one

sudo dnf install nginx -y

sudo systemctl start nginx
sudo systemctl enable nginx

With this Nginx has been installed and started. Let’s proceed to the third step

Step 3 – Install and configure Firewall

The third step is to install and configure firewall so that our server allows the incoming traffic from http and https ports.

sudo dnf install firewalld -y

Now that the firewall is installed, lets start and enable it

sudo systemctl start firewalld
sudo systemctl enable firewalld

Lets add rules to allow incoming traffic from http and https ports.

sudo firewall-cmd --zone=public --add-service=http --permanent
sudo firewall-cmd --zone=public --add-service=https --permanent
sudo firewall-cmd --reload

With this our firewall is installed and configured. Now lets proceed to fourth step

Step 4 – Install and Configure MariaDB

Fourth step is to install and configure MariaDB which will be the database for WordPress

sudo dnf install mariadb-server -y

Start and Enable MariaDB services

sudo systemctl start mariadb
sudo systemctl enable mariadb

Lets first secure our database, then we will go ahead with creating database

sudo mysql_secure_installation

Enter current password for root (enter for none): (Just hit enter key)
Switch to unix_socket authentication [Y/n]: (Press N and hit enter key)
Change the root password? [Y/n]: (Press Y and hit enter key)
Enter New Password:
Confirm New Password: 
Note:- Make sure to enter a strong and memorable password here

Remove anonymous users? [Y/n]: (Press Y and hit enter key)
Disallow root login remotely? [Y/n]: (Press Y and hit enter key)
Remove test database and access? [Y/n]: (Press Y and hit enter key)
Reload privilege tables now? [Y/n]: (Press Y and hit enter key)

Now to create database lets first login to mysql

sudo mysql -u root -p

Now execute the scripts below to setup complete database. Make sure to go through the “Note” I have added below before running the scripts.

CREATE DATABASE wordpress DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_520_ci;
GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpressuser'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
EXIT;

Note:- Make sure to change the given below as per your need

“wordpress” – This is the name of your WordPress database. You can change it as per your wish
“wordpressuser” – This is the user name of your database user who will have access to your database. You can change it as per your wish
“password” – This is database’s password. Change it to something stronger

With this we have setup our database. Now lets proceed to step five

Step 5 – Install PHP 8.5

At the time of publishing this post, PHP 8.5 was the latest release and so I have installed the same. Execute the commands below one by one to install PHP 8.5 on your server

sudo dnf install epel-release -y
sudo dnf install https://rpms.remirepo.net/enterprise/remi-release-10.rpm -y
sudo dnf module reset php -y
sudo dnf module enable php:remi-8.5 -y
sudo dnf install php-fpm php-curl php-gd php-imagick php-intl php-mbstring php-xml php-zip php-mysqli php-mysqlnd php-bcmath -y

By default PHP use apache as user and group, since we are using nginx lets configure PHP to use nginx user and group.

sudo nano /etc/php-fpm.d/www.conf

scroll down a bit and you will find

user = apache
group = apache

change both parameters to

user = nginx
group = nginx

press ctrl+x, y, hit enter

Now lets restart php-fpm service for the changes to effect

sudo systemctl restart php-fpm

With this, PHP 8.5 has been installed on your server. Let’s proceed to sixth step

Step 6 – Configuring Nginx

Now the next step is to configure Nginx configuration file. For that we will create a new .conf file with our domain name

sudo nano /etc/nginx/conf.d/your_domain.conf

Note:- Make sure to change “your_domain” to your real domain name

Now copy and paste the given below to your_domain.conf file

server {
    listen 80;
    listen [::]:80;
    server_name your_domain.com www.your_domain.com;
    root /var/www/html/your_domain;
    index index.html index.htm index.php;

    location / {
        try_files $uri $uri/ /index.php$is_args$args;
    }

    location = /favicon.ico { log_not_found off; access_log off; }
    location = /robots.txt { log_not_found off; access_log off; allow all; }
    location ~* \.(css|gif|ico|jpeg|jpg|js|png)$ {
        expires max;
        log_not_found off;
    }
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/run/php-fpm/www.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

Note:- Make sure to change “your_domain” to your real domain name

Now lets compile and test whether nginx configuration is correct

sudo nginx -t

Now lets restart nginx

sudo systemctl restart nginx

With this our Nginx configuration is completed.

Step 7 – Downloading and Configuring WordPress

Next step is to download the latest WordPress from official source to our /tmp folder and configure it

cd /tmp
sudo curl -LO https://wordpress.org/latest.tar.gz
sudo tar xzvf latest.tar.gz -C /var/www/html/
cd /var/www/html/
sudo mv wordpress/ your_domain
cd your_domain
sudo cp wp-config-sample.php wp-config.php
sudo nano wp-config.php

Fill the database details as per step 4 in the given below fields

define('DB_NAME', 'wordpress');

/** MySQL database username */
define('DB_USER', 'wordpressuser');

/** MySQL database password */
define('DB_PASSWORD', 'password');

...

define('FS_METHOD', 'direct');

Press ctrl+x, y and hit enter to save.

Let’s assign correct permission to our WordPress folder

sudo chown -R nginx:nginx /var/www/html/your_domain

Step 8 – Disabling SELinux

To allow the WordPress and other plugins to work properly, we will have to disable SELinux. Open the SELinux configuration file and make the following changes

sudo nano /etc/selinux/config

Scroll down and find

SELINUX=permissive

change the parameter to

SELINUX=disabled

Press ctrl+x,y, and hit enter key.

Step 9 – Configuring SSL

The final step is to configure SSL. I have used LetsEncrypt SSL which is free and offers good amount of encryption. Lets first install certbot which will configure SSL and also renews it automatically.

sudo dnf install certbot python3-certbot-nginx -y

Now lets get our certificate

sudo certbot --nginx -d your_domain.com -d www.your_domain.com

Note: Make sure to change your_domain with your real domain

It will ask for your email address, enter it and press enter key

Then press “Y” and hit enter in both the prompts, one is to accept the terms and conditions and other is to join LetsEncrypt’s email subscription.

Restart your VPS

sudo reboot

Now on any browser, open “https://your_domain.com” and finalize the setup.

Note: Make sure to change your_domain with your real domain
