Here’s a step-by-step guide to install WordPress on Ubuntu (20.04/22.04) using a LAMP stack (Linux, Apache, MySQL, PHP):

---

✅ Step 1: Update Your System

Open your terminal and run:

sudo apt update && sudo apt upgrade -y

---

✅ Step 2: Install Apache Web Server

sudo apt install apache2 -y

Enable and start Apache:

sudo systemctl enable apache2
sudo systemctl start apache2

---

✅ Step 3: Install MySQL (Database Server)

sudo apt install mysql-server -y

Secure MySQL:

sudo mysql_secure_installation

Follow the prompts to set root password and remove test users/databases.

---

✅ Step 4: Create a MySQL Database for WordPress

Log into MySQL:

sudo mysql -u root -p

Then run:

CREATE DATABASE wordpress;
CREATE USER 'wpuser'@'localhost' IDENTIFIED BY 'your_strong_password';
GRANT ALL PRIVILEGES ON wordpress.* TO 'wpuser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

---

✅ Step 5: Install PHP and Required Extensions

sudo apt install php php-mysql php-curl php-gd php-xml php-mbstring php-xmlrpc php-soap php-intl php-zip libapache2-mod-php -y

Restart Apache to apply PHP:

sudo systemctl restart apache2

---

✅ Step 6: Download and Configure WordPress

Navigate to /tmp:

cd /tmp

Download WordPress:

curl -O https://wordpress.org/latest.tar.gz

Extract the archive:

tar -xvzf latest.tar.gz

Move WordPress to the web root:

sudo rsync -av wordpress/ /var/www/html/

---

✅ Step 7: Set Permissions

sudo chown -R www-data:www-data /var/www/html/
sudo find /var/www/html/ -type d -exec chmod 755 {} \;
sudo find /var/www/html/ -type f -exec chmod 644 {} \;

---

✅ Step 8: Configure Apache for WordPress

Create a virtual host file:

sudo nano /etc/apache2/sites-available/wordpress.conf

Paste this:

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html
    ServerName your_domain_or_IP

    <Directory /var/www/html>
        AllowOverride All
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Enable the site and rewrite module:

sudo a2ensite wordpress.conf
sudo a2enmod rewrite
sudo systemctl restart apache2

---

✅ Step 9: Configure WordPress

Rename the sample config:

cd /var/www/html
sudo mv wp-config-sample.php wp-config.php

Edit it:

sudo nano wp-config.php

Update the database settings:

define( 'DB_NAME', 'wordpress' );
define( 'DB_USER', 'wpuser' );
define( 'DB_PASSWORD', 'your_strong_password' );
define( 'DB_HOST', 'localhost' );

Save and exit.
