How To Install WordPress with LEMP on CentOS 7

To install WordPress on a CentOS 7 server with the LEMP stack, follow these steps.

Step 1 : Install LEMP Stack

If you haven't installed the LEMP stack yet, please follow the instructions in the CentOS 7 Guides to set it up.

Step 2 : Create a Database

First, log in to your MySQL/MariaDB server:

sudo mysql

Create a new database for WordPress:

CREATE DATABASE wordpress_db;

Create a new user and grant them permissions on the database:

CREATE USER 'wordpress_user'@'localhost' IDENTIFIED BY 'your_password';
GRANT ALL PRIVILEGES ON wordpress_db.* TO 'wordpress_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Step 3 : Download and Install WordPress

Create the WordPress directory:

sudo mkdir -p /var/www/html/example.devtutorial.io

Navigate to the directory and download WordPress:

cd /var/www/html/example.devtutorial.io
sudo wget https://wordpress.org/latest.tar.gz

Extract the WordPress archive:

sudo tar -xzvf latest.tar.gz

Move the extracted files to the desired location:

sudo mv wordpress/* .

Set the correct permissions:

sudo chown -R nginx:nginx /var/www/html/example.devtutorial.io
sudo chmod -R 755 /var/www/html/example.devtutorial.io

Step 4 : Configure Nginx for example.devtutorial.io

Create a new Nginx server block configuration file:

sudo nano /etc/nginx/conf.d/example.devtutorial.io.conf

Add the following configuration:

server {
    listen 80;
    server_name example.devtutorial.io;
    root /var/www/html/example.devtutorial.io;
    index index.php index.html index.htm;


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

    location ~ \.php$ {
        fastcgi_pass unix:/var/run/php-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $request_filename;
        include fastcgi_params;
    }
}

Step 5 : Test Configuration and Restart Nginx

Test the Nginx configuration:

sudo nginx -t

Restart Nginx to apply the changes:

sudo systemctl restart nginx

Step 6 : Configure SELinux (if enabled)

If SELinux is enabled, run the following command:

sudo semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/example.devtutorial.io(/.*)?'
sudo restorecon -Rv /var/www/html/example.devtutorial.io

Step 7 : Complete the WordPress Installation via Browser

Open your browser and navigate to:

http://example.devtutorial.io

Select your preferred language and click "Let's go!".

Fill in the database details:

- Database Name: wordpress_db

- Username: wordpress_user

- Password: your_password

- Database Host: localhost

- Table Prefix: wp_

Click "Run the installation".

Fill in the site information and click "Install WordPress".

Step 8 : After installation, log in to WordPress with your credentials.

Step 9 :Once logged in, you will be redirected to the WordPress dashboard where you can start customizing your site.
