Introduction: In this tutorial, we will guide you through the process of installing WordPress on a CentOS 7 server. Before starting, ensure that you meet the following prerequisites:
Prerequisites:
- A server with Linux CentOS 7.
- LAMP Stack (Linux, Apache, MySQL, PHP) installed. If not, follow our LAMP Stack installation tutorial.
- Root access to your server.
- SSH tools:
- For Windows: PuTTY
- For Linux/macOS: OpenSSH (available by default)
We will use the following information from the LAMP Stack tutorial in this WordPress installation:
- Main Domain: example.com
- Sub Domain: holu.example.com
- MySQL root password: holuP455##
Let's get started!
Step 1: Create a MySQL Database with a User and Password Step 1.1: Login to MySQL (as root):
mysql -u root -p
Step 1.2: Create users (and passwords): For example.com:
CREATE USER 'example'@'localhost' IDENTIFIED BY '#TH15exmp#';
For holu.example.com:
CREATE USER 'holu'@'localhost' IDENTIFIED BY '#TH15holu#';
Step 1.3: Create the database: For example.com:
CREATE DATABASE exampledb;
For holu.example.com:
CREATE DATABASE holudb;
Step 1.4: Grant the user access rights: This command will give both users full access to their respective databases:
GRANT ALL PRIVILEGES ON exampledb.* TO 'example'@'localhost' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON holudb.* TO 'holu'@'localhost' WITH GRANT OPTION;
To save the changes, run:
FLUSH PRIVILEGES;
Now exit MySQL with:
quit
Step 2: Install and Configure WordPress Step 2.1: Download and Extract WordPress:
cd /tmp
wget https://wordpress.org/latest.tar.gz
tar -xvf latest.tar.gz
cd wordpress
Step 2.2: Copy the WordPress Files to the Public_HTML Directory and Grant Apache Access:
For example.com:
mkdir -p /var/www/html/example.com/public_html
cp -r * /var/www/html/example.com/public_html
chown -R apache:apache /var/www/html/example.com/public_html
find /var/www/html/example.com/public_html -type d -exec chmod 755 {} \;
find /var/www/html/example.com/public_html -type f -exec chmod 644 {} \;
For holu.example.com:
mkdir -p /var/www/html/holu.example.com/public_html
cp -r * /var/www/html/holu.example.com/public_html
chown -R apache:apache /var/www/html/holu.example.com/public_html
find /var/www/html/holu.example.com/public_html -type d -exec chmod 755 {} \;
find /var/www/html/holu.example.com/public_html -type f -exec chmod 644 {} \;
Step 2.3: Configure WordPress to Access your website from the browser (example.com and holu.example.com). If you see the standard WordPress page, the installation was successful.
- Click "Let's go" to configure the database settings.
- Set the website details, username, and password.
- If successful, you'll be redirected to the login page.
Repeat Step 2.3 for holu.example.com and any other websites you want to add.
Optional: Fixes for Potential Errors
- Database Error: If you encounter a database error, you can fix it by editing the MySQL configuration, as explained in the tutorial.
- Cannot Write wp-config.php Error: If you face a "Cannot write wp-config.php" error, check and grant Apache user access to your public_html directory.
Conclusion: Your CentOS 7 server is now ready to host WordPress websites. You can add more websites following the same steps. Enjoy your WordPress hosting!
