Hi,
I want to install centreon with this configuration :
- Centreon server with centreon-central
- Database on remote mariadb server
All are in Debian 12.
For the centreon central, the install is :
apt update
apt upgrade
apt update && apt install lsb-release ca-certificates apt-transport-https software-properties-common wget gnupg2 curl
ip a
apt update
apt upgrade
apt autoremove
echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" | tee /etc/apt/sources.list.d/sury-php.list
wget -O- https://packages.sury.org/php/apt.gpg | gpg --dearmor | tee /etc/apt/trusted.gpg.d/php.gpg > /dev/null 2>&1
echo "deb https://packages.centreon.com/apt-standard/ $(lsb_release -sc)-25.10-stable main" | tee -a /etc/apt/sources.list.d/centreon-25.10-stable.list
echo "deb https://packages.centreon.com/apt-plugins-stable/ $(lsb_release -sc) main" | tee /etc/apt/sources.list.d/centreon-plugins.list
wget -O- https://apt-key.centreon.com | gpg --dearmor | tee /etc/apt/trusted.gpg.d/centreon.gpg > /dev/null 2>&1
apt update
apt install -y centreon-central
systemctl enable php8.2-fpm apache2 centreon cbd centengine gorgoned centreontrapd snmpd snmptrapd
ss -ltnpI have the 80 listen socket.
On the remote database server :
MariaDB [(none)]> CREATE DATABASE centreon_db;
Query OK, 1 row affected (0.000 sec)
MariaDB [(none)]> CREATE USER 'centreon_user'@'IP_CENTRAL' IDENTIFIED BY '<REDACTED>';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON centreon_db.* TO 'centreon_user'@'IP_CENTRAL' WITH GRANT OPTION;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.001 sec)
All telnet tests are OK.
When I want to start the Web installer, I’ve a blank page :
Logs are :
- Apache 2 : HTTP 200 => OK
