GLPI is a web application and thus requires the basic components of LAMP/LEMP stack. In this demo, we are using LAMP Stack and thus;

Install and enable Remi repos as they provide some of the required PHP modules.

dnf install epel-release
dnf install

Enable Remi Repos for PHP 7.4.

dnf module reset php
dnf module enable php:remi-7.4

Execute the command below to install all GLPI LAMP stack requirements;

Note, GLPI requires PHP > 5.6, MySQL > 5.6 or MariaDB > 10.0.

dnf update
dnf install httpd mariadb-server php php-{curl,fileinfo,gd,json,mbstring,mysqli,session,zlib,simplexml,xml,cli,domxml,imap,ldap,openssl,xmlrpc,pecl-apcu} wget tar zip bzip2

Configure PHP for GLPI

Edit the PHP configuration file, php.ini and ensure the following settings are in place.

vim /etc/php.ini

Set the Maximum amount of memory;

memory_limit = 128M

Enable file uploads;

file_uploads = On

Set Maximum execution time;

max_execution_time = 30

Disable session initialization on request startup.

session.auto_start = 0

Disable the use of trans sid.

session.use_trans_sid = 0

Create GLPI Database and Database User

In this demo, we are using MariaDB as our database server.

Start and enable MariaDB to run on system boot;

systemctl enable --now mariadb

Run the initial security script.


Login to MariaDB and create GLPi database. Be sure to replace the databse name used here accordingly.

mysql -u root -p
create database glpidb;

Next, create GLPI database user and grant all rights on GLPI database.

grant all on glpidb.* to glpiadmin@localhost identified by 'myP@ssw0rd';

Reload the privileges table and exit the database.

flush privileges;

Download GLPI Installer

Navigate to GLPI downloads page or GLPI GitHub releases page and grab the latest stable release, which is v9.4.5 as of this writing. Get the link and pull it with wget command.


Install GLPI on CentOS 8

GLPI is a ready made application and its installation is as easy as extracting the archive contents to the GLPI web root directory. In this demo, our GLPI web root directory is set to /var/www/html/glpi.

tar xzf glpi-9.4.5.tgz -C /var/www/html/

Verify the GLPI web root directory;

ls /var/www/html/

Set the proper ownership and permissions on the GLPI web server configuration files.

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

Create Apache configuration file for GLPI.

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

Make the appropriate substitutions in the configuration file to suit your environment.

<VirtualHost *:80>
   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> /var/www/html/glpi/files>
           AllowOverride None
           Require all denied

To setup GLPI with TLS certificates install mod_ssl package.

dnf install mod_ssl

Edit the /etc/httpd/conf.d/ssl.conf configuration file and set the correct paths to the TLS certificate, the CA certificate, if any, and certificate key file.

vim +/SSLCertificateFile /etc/httpd/conf.d/ssl.conf

Note that the configs below are Self-Signed Certificates and hence, no CA certificate specified. Be sure to obtain your certificates from a trusted CA and make appropriate configs.

SSLCertificateFile /etc/pki/tls/certs/server.crt
SSLCertificateKeyFile /etc/pki/tls/private/server.key

Then enable HTTPS for GLPI by editing the GLPI Apache configuration file created above, You can as well enable HTTP-HTTPS redirection;

vim /etc/httpd/conf.d/glpi.conf
<VirtualHost *:80>
   DocumentRoot /var/www/html/glpi

   RewriteEngine On
   RewriteCond %{HTTPS} off
   RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
<VirtualHost *:443>
   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> /var/www/html/glpi/files>
           AllowOverride None
           Require all denied
   SSLEngine on
   SSLCertificateKeyFile /etc/pki/tls/private/server.key
   SSLCertificateFile /etc/pki/tls/certs/server.crt

Verify Apache configuration syntax.

httpd -t
Syntax OK

If you moved SSL/TLS files to the specified directories instead of copying them, you need to correct the SELinux contexts on those files by running the command below;

restorecon -RvF /etc/pki

Start and enable Apache to run on system boot.

systemctl enable --now httpd

If firewall is running, allow external access to Apache.

firewall-cmd --add-port={80,443}/tcp --permanent
firewall-cmd --reload

Configure other SELinux Permissions for GLPI

In our demo, SELinux is set on enforcing mode. Hence, run the commands below to set the SELinux permissions for GLPI.

setsebool -P httpd_unified 1
setsebool -P httpd_can_network_connect 1
setsebool -P httpd_graceful_shutdown 1
setsebool -P httpd_can_network_relay 1
setsebool -P nis_enabled 1
setsebool -P httpd_can_network_connect_db 1
setsebool -P httpd_can_sendmail on
