Install GLPI on CentOS 8 / RHEL 8 / Rocky Linux 8

Let’s now dive into the installation of GLPI on CentOS 8 / RHEL 8 Linux distribution.The process involves installation of dependent packages such as database server.

Step 1: Install MariaDB Database server

GLPI requires a relational database to store its data. Let’s install MariaDB on our CentOS /RHEL 8 system using our guide below.

• Install MariaDB on RHEL / CentOS 8

Confirm MariaDB service is in running state:

$ systemctl status mariadb
● mariadb.service - MariaDB 10.3 database server
   Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled; vendor preset: disabled)

After installation of Database, Create GLPI database and account.

$ mysql -u root -p
CREATE USER 'glpi'@'%' IDENTIFIED BY 'glpiDBSecret';
GRANT USAGE ON *.* TO 'glpi'@'%' IDENTIFIED BY 'glpiDBSecret';
CREATE DATABASE IF NOT EXISTS `glpi` ;
GRANT ALL PRIVILEGES ON `glpi`.* TO 'glpi'@'%';
FLUSH PRIVILEGES;
exit

Check the database connection.

$ mysql -uglpi -pglpiDBSecret glpi

Step 2: Install GLPI on CentOS 8|RHEL 8|Rocky Linux 8

Now we install the dependencies required and GLPI. Start by resetting PHP module

sudo dnf module reset -y  php

List available PHP AppStream modules.

$ dnf module list php
Last metadata expiration check: 0:18:12 ago on Wed 16 Aug 2023 10:47:30 AM UTC.
CentOS Stream 8 - AppStream
Name                                   Stream                                    Profiles                                                     Summary
php                                    7.2 [d]                                   common [d], devel, minimal                                   PHP scripting language
php                                    7.3                                       common [d], devel, minimal                                   PHP scripting language
php                                    7.4                                       common [d], devel, minimal                                   PHP scripting language
php                                    8.0                                       common [d], devel, minimal                                   PHP scripting language

Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled

We’ll enable and use PHP 8.0

sudo dnf module install -y  php:8.0

Now install PHP and other dependencies.

sudo dnf install php php-{mysqlnd,gd,intl,ldap,apcu,opcache,zip,xml}

Install, start and enable httpd service.

sudo dnf -y install httpd vim wget unzip
sudo systemctl enable --now httpd php-fpm

If you have firewalld service, allow http port.

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

Turn on some SELinux booleans required.

sudo setsebool -P httpd_can_network_connect on
sudo setsebool -P httpd_can_network_connect_db on
sudo setsebool -P httpd_can_sendmail on

Download GLPI tarball:

VERSION=$(curl --silent "https://api.github.com/repos/glpi-project/glpi/releases/latest" | grep '"tag_name"' | sed -E 's/.*"([^"]+)".*/\1/')
wget https://github.com/glpi-project/glpi/releases/download/${VERSION}/glpi-${VERSION}.tgz

Extract downloaded archive file.

tar xvf glpi-${VERSION}.tgz

Move the glpi directory /var/www/html directory:

sudo mv glpi /var/www/html

Set directory permissions

sudo chmod -R 755 /var/www/html/glpi
sudo chown -R apache:apache /var/www/html/glpi

Configure SELinux:

sudo dnf -y install policycoreutils-python-utils
sudo semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/html/glpi(/.*)?"
sudo restorecon -Rv /var/www/html/glpi

Step 3: Configure Web Server for GLPI

Initial installation from the web browser is only allowed via local access (from the GLPI server). Add your IP address to allow remote installation.

Create Apache httpd configuration file:

sudo vim /etc/httpd/conf.d/glpi.conf

Add add the

<VirtualHost *:80>
   ServerName glpi.example.com
   DocumentRoot /var/www/html/glpi

   ErrorLog "/var/log/httpd/glpi_error.log"
   CustomLog "/var/log/httpd/glpi_access.log" combined

   <Directory> /var/www/html/glpi/config>
           AllowOverride None
           Require all denied
   </Directory>
   <Directory> /var/www/html/glpi/files>
           AllowOverride None
           Require all denied
   </Directory>
</VirtualHost>

Then access GLPI web console to complete GLPI installation on CentOS 8 / RHEL 8.

http://ServerIP_or_Hostname/glpi/

Step 4: Configure GLPI on Web Browser

You can also access the installer on http://server_ip/glpi/install/install.php. Follow next installation steps to complete setup. If using DNS name then it can be accessed on http://glpi.example.com

Select Language and Accept License.

Choose install.

All compatibility checks of your environment with the execution of GLPI should pass.

Provide database access credentials for Data population.

Select glpi existing database in your next screen.

Initialization should finish in few seconds.

Follow other prompts to get to the last page with access credentials.

Default initial logins / passwords are:

• glpi/glpi for the administrator account
• tech/tech for the technician account
• normal/normal for the normal account
• post-only/postonly for the postonly account

Login and change the default login credentials.

To this stage, GLPI is installed on CentOS 8|RHEL 8|Rocky Linux 8. The remaining bit is on customization and building up a database with all your company inventory – computer, servers, software, printers, cameras, alarms e.t.c.

Check official documentation on GLPI configuration to manage your Infrastructure assets.
