In this tutorial we’ll show you how to install WordPress on Debian 12 OS.

Step 1: Update Operating System

Update your Debian 12 operating system to make sure all existing packages are up to date:

# apt update && apt upgrade

Also, install necessary packages:

# apt install nano wget unzip

Step 2: Install Nginx web server on Debian 12

To install Nginx, run the following command:

# apt install nginx

You can start the Nginx service and configure it to run on startup by entering the following commands:

# systemctl start nginx
# systemctl enable nginx

Verify the status of the Nginx service using systemctl status command:

# systemctl status nginx

● nginx.service - A high performance web server and a reverse proxy server
     Loaded: loaded (/lib/systemd/system/nginx.service; enabled; preset: enabled)
     Active: active (running)
       Docs: man:nginx(8)
    Process: 674 ExecStartPre=/usr/sbin/nginx -t -q -g daemon on; master_process on; (code=exited, status=0/SUCCESS)
    Process: 873 ExecStart=/usr/sbin/nginx -g daemon on; master_process on; (code=exited, status=0/SUCCESS)
   Main PID: 875 (nginx)
      Tasks: 2 (limit: 2273)
     Memory: 4.5M
        CPU: 402ms
     CGroup: /system.slice/nginx.service
             ├─875 "nginx: master process /usr/sbin/nginx -g daemon on; master_process on;"
             └─876 "nginx: worker process"

Step 3: Install PHP and PHP extensions for WordPress

You can install PHP and other supporting packages using the following command:

# apt install php php-curl php-fpm php-bcmath php-gd php-soap php-zip php-curl php-mbstring php-mysqlnd php-gd php-xml php-intl php-zip

Verify if PHP is installed.

php -v

Output:

PHP 8.2.7 (cli) (built: Jun  9 2023 19:37:27) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.2.7, Copyright (c) Zend Technologies
    with Zend OPcache v8.2.7, Copyright (c), by Zend Technologies

After installing all the packages, edit the php.ini file:

# nano /etc/php/8.2/fpm/php.ini

Change the following settings per your requirements:

max_execution_time = 300
memory_limit = 512M
post_max_size = 128M
upload_max_filesize = 128M

To implement the changes, restart the php-fpm service:

# systemctl restart php8.2-fpm

Step 4: Install MariaDB Database Server

You can install MariaDB with the following command:

# apt install mariadb-server mariadb-client

Start the database server daemon, and also enable it to start automatically at the next boot with the following commands:

# systemctl start mariadb
# systemctl enable mariadb

Verify the status of the MariaDB service using systemctl status command:

# systemctl status mariadb

Output:

● mariadb.service - MariaDB 10.11.3 database server
     Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; preset: enabled)
     Active: active (running)
       Docs: man:mariadbd(8)
             https://mariadb.com/kb/en/library/systemd/
   Main PID: 959 (mariadbd)
     Status: "Taking your SQL requests now..."
      Tasks: 12 (limit: 2273)
     Memory: 256.5M
        CPU: 6.621s
     CGroup: /system.slice/mariadb.service
             └─959 /usr/sbin/mariadbd

Once the database server is installed, run the following command to secure your MariaDB server:

# mysql_secure_installation

You will then be asked several configuration questions, which you must answer Y to each of them.

Remove anonymous users? [Y/n]: Y
Disallow root login remotely? [Y/n]: Y
Remove test database and access to it? [Y/n]:  Y
Reload privilege tables now? [Y/n]:  Y

Restart the database server for the changes to take effect.

# systemctl restart mariadb

Step 5: Create a New Database for WordPress

To do this, log in to your MariaDB server using the following command:

# mysql -u root -p

Run the following commands to create a new database and user:

MariaDB [(none)]> CREATE DATABASE wordpress_db;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON wordpress_db.* TO 'wordpress_user'@'localhost' IDENTIFIED BY 'password';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> EXIT

Note: Make sure to replace 'password' with a strong password of your choice.

Step 6: Download WordPress

We will now download the latest version of WordPress from the WordPress Official site.

Use the following command to download WordPress:

# wget https://wordpress.org/latest.zip

Extract file into the folder /var/www/html/ with the following command,

# unzip latest.zip -d /var/www/html/

Next, navigate to the  /var/www/html/wordpress/ directory:

# cd /var/www/html/wordpress

WordPress comes with a configuration sample file. Make a copy of this file:

# cp wp-config-sample.php wp-config.php

Next, edit the WordPress configuration file and define your database settings:

# nano wp-config.php

Change the following lines that match your database settings:

/** The name of the database for WordPress */
define( 'DB_NAME', 'wordpress_db' );

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

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

/** MySQL hostname */
define( 'DB_HOST', 'localhost' );

Save the file when you are finished.

Change the permission of the website directory:

# chown -R www-data:www-data /var/www/html/wordpress/

Step 7: Configure Nginx Web Server for WordPress

Navigate to /etc/nginx/conf.d directory and run the following command to create a configuration file for your installation:

# nano /etc/nginx/conf.d/wordpress.conf

Add the following content:

server {
  listen 80;

    server_name  your-domain.com www.your-domain.com;
    root   /var/www/html/wordpress;
    index  index.php;

    access_log /var/log/nginx/your-domain.com.access.log;
    error_log /var/log/nginx/your-domain.com.error.log;

    client_max_body_size 100M;

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

    location ~ \.php$ {
         include snippets/fastcgi-php.conf;
         fastcgi_pass unix:/var/run/php/php8.2-fpm.sock;
         include fastcgi_params;
         fastcgi_intercept_errors on;
    }
}

Save the file and Exit.

Restart the Nginx web server.

# systemctl restart nginx

The post How to Install WordPress on Debian 12 appeared first on LinuxTuto.

In this tutorial we’ll show you how to setup a LAMP (Linux, Apache, MySQL/MariaDB, PHP) stack and install WordPress on AlmaLinux 9 OS.

Step 1: Update Operating System

Update your AlmaLinux 9 operating system to make sure all existing packages are up to date:

$ sudo dnf update && sudo dnf upgrade -y

Also, install:

$ sudo dnf install nano wget unzip

Step 2: Install Apache web server on AlmaLinux 9

You can install Apache via dnf package manager by executing the following command.

$ sudo dnf install httpd

You can start the httpd service and configure it to run on startup by entering the following commands:

$ sudo systemctl start httpd
$ sudo systemctl enable httpd

Verify the status of the httpd service using systemctl status command:

$ sudo systemctl status httpd

Output:

● httpd.service - The Apache HTTP Server
     Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)
     Active: active (running)
       Docs: man:httpd.service(8)
   Main PID: 10643 (httpd)
     Status: "Total requests: 0; Idle/Busy workers 100/0;Requests/sec: 0; Bytes served/sec:   0 B/sec"
      Tasks: 213 (limit: 5738)
     Memory: 28.9M
        CPU: 198ms
     CGroup: /system.slice/httpd.service
             ├─10643 /usr/sbin/httpd -DFOREGROUND
             ├─10644 /usr/sbin/httpd -DFOREGROUND
             ├─10645 /usr/sbin/httpd -DFOREGROUND
             ├─10646 /usr/sbin/httpd -DFOREGROUND
             └─10647 /usr/sbin/httpd -DFOREGROUND

If firewalld is enabled consider allowing HTTP and HTTPS services:

$ sudo firewall-cmd --permanent --add-service={http,https}
$ sudo firewall-cmd --reload

You can test to make sure everything is working correctly by navigating to:

http://your-IP-address

If everything is configured properly, you should be greeted by the default Apache2 Page, as seen below.

Step 3: Install PHP and PHP extensions for WordPress

You can install PHP and other supporting packages using the following command:

$ sudo dnf install php php-curl php-bcmath php-gd php-soap php-zip php-curl php-mbstring php-mysqlnd php-gd php-xml php-intl php-zip

Verify if PHP is installed.

php -v

Output:

PHP 8.0.13 (cli) (built: Nov 16 2021 18:07:21) ( NTS gcc x86_64 )
Copyright (c) The PHP Group

Step 4: Install MariaDB and create a database

You can install MariaDB with the following command:

$ sudo dnf install mariadb-server mariadb

Start the database server daemon, and also enable it to start automatically at the next boot with the following commands:

$ systemctl start mariadb
$ systemctl enable mariadb

Verify the status of the MariaDB service using systemctl status command:

$ sudo systemctl status mariadb

Output:

● mariadb.service - MariaDB 10.5 database server
     Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled; vendor preset: disabled)
     Active: active (running)
       Docs: man:mariadbd(8)
             https://mariadb.com/kb/en/library/systemd/
   Main PID: 13088 (mariadbd)
     Status: "Taking your SQL requests now..."
      Tasks: 11 (limit: 5738)
     Memory: 73.5M
        CPU: 390ms
     CGroup: /system.slice/mariadb.service
             └─13088 /usr/libexec/mariadbd --basedir=/usr

Once the database server is installed, run the following command to secure your MariaDB server:

$ sudo mysql_secure_installation

Use the following options for the prompt.

Enter current password for root (enter for none): Just press the Enter
Set root password? [Y/n]: Y
New password: Enter your password
Re-enter new password: Repeat your password
Remove anonymous users? [Y/n]: Y
Disallow root login remotely? [Y/n]: Y
Remove test database and access to it? [Y/n]:  Y
Reload privilege tables now? [Y/n]:  Y

Restart the database server for the changes to take effect.

$ sudo systemctl restart mariadb

Login to MariDB shell using the following command:

$ sudo  mysql -u root -p

To create a database, database user, and grant all privileges to the database user run the following commands:

MariaDB [(none)]> CREATE DATABASE wordpress_db;
MariaDB [(none)]> CREATE USER 'wordpress_user'@'localhost' IDENTIFIED BY 'PaSSw0rd';
MariaDB [(none)]> GRANT ALL ON wordpress_db.* TO 'wordpress_user'@'localhost';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> EXIT

Step 5: Download WordPress on AlmaLinux 9

We will now download the latest version of WordPress from the WordPress Official site.

Use the following command to download WordPress:

$ sudo wget https://wordpress.org/latest.zip

Extract file into the folder /var/www/html/ with the following command,

$ sudo unzip latest.zip -d /var/www/html/

Change the permission of the website directory:

$ sudo chown -R apache:apache /var/www/html/wordpress/
$ sudo chcon -t httpd_sys_rw_content_t /var/www/html/wordpress -R
