How to Install WordPress on AlmaLinux 9

---

WordPress is a Content Management System (CMS), a platform you can use to build and maintain a website without any knowledge of coding. This software enables you to customize just about every aspect of your site.

Prerequisites:

---

WordPress requires LAMP stack installed and running

For detailed installation, refer to LAMP Stack on Almalinux 9

Update Firewall Settings

---

The below commands will open or allow the HTTP (port 80) and HTTPS (port 443) and then reload the firewall configuration to effect.

firewall-cmd --permanent --zone=public --add-service=http

firewall-cmd --permanent --zone=public --add-service=https

firewall-cmd --reload

Output:

[root@server ~]# firewall-cmd --permanent --zone=public --add-service=http
success
[root@server ~]# firewall-cmd --permanent --zone=public --add-service=https
success
[root@server ~]# firewall-cmd --reload
success

Secure MariaDB Installation

---

Next, we secure our MariaDB installation and setup a root password for MariaDB

mysql_secure_installation

Output:

[root@server ~]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password:
Re-enter new password:

Creating the new Database

---

Log into MySQL with the following command,

mysql -u root -p

First, we'll create a new database,

CREATE DATABASE wordpress;

Next, create a new MySQL user account that we will use to operate on WordPress's new database, with the username "admin"

CREATE USER `admin`@`localhost` IDENTIFIED BY '<Enter Strong Password here>';

Link the user and DB together by granting our user access to the database,

GRANT ALL ON wordpress.* TO `admin`@`localhost`;

Flush the privileges so that MySQL knows about the user permissions we just added,

FLUSH PRIVILEGES;

Exit out of the MySQL command prompt by typing,

exit

Output:

MariaDB [(none)]> CREATE DATABASE wordpress;
Query OK, 1 row affected (0.002 sec)

MariaDB [(none)]> CREATE USER `admin`@`localhost` IDENTIFIED BY 'STRONG PASSWORD HERE';
Query OK, 0 rows affected (0.003 sec)

MariaDB [(none)]> GRANT ALL ON wordpress.* TO `admin`@`localhost`;
Query OK, 0 rows affected (0.002 sec)

MariaDB [(none)]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.002 sec)

MariaDB [(none)]> exit

Download and Extract WordPress

---

Download the WordPress by using the curl command,

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

Install tar command to extract wordpress file using below command,

dnf install tar -y 

Extract the wordpress file using below command,

tar xf wordpress.tar.gz

Copy the extracted WordPress directory into the /var/www/html directory

cp -r wordpress /var/www/html

File Permissions

---

Change permissions and change file SELinux security context

chown -R apache:apache /var/www/html/wordpress

chcon -t httpd_sys_rw_content_t /var/www/html/wordpress -R

Allow Apache to access the internet to allow WordPress to download plugins and updates directly from WordPress.org,

setsebool -P httpd_can_network_connect true
