Using sources
Prerequisites
Most CentOS users will find easier to install Centreon Web by using packages.
To install Centreon you will need to set up the official software collections repository supported by Redhat.
Software collections are required for installing PHP 7 and associated libraries (Centreon requirement).
Install the software collections repository using this command:
yum install -y centos-release-scl
The repository is now installed.
You can now install the necessary prerequisites:
yum update
yum install -y \
rh-php72 \
rh-php72-php-zip \
rh-php72-php-xml \
rh-php72-php-fpm \
rh-php72-php-process \

rh-php72-php-pdo \
rh-php72-php-intl \
rh-php72-php-pear \

net-snmp-libs \
dmidecode \
lm_sensors \
net-snmp-perl \
fping \
cpp \
gcc \
gcc-c++ \
libstdc++ \
glib2-devel
Additional commands are necessary to configure the environment correctly:
usermod -U apache
/opt/rh/rh-php72/root/bin/pear channel-update pear.php.net
If you can’t access the Internet directly but have to pass via a proxy, perform the following command:
/opt/rh/rh-php72/root/bin/pear config-set http_proxy http://my_proxy.com:port
Then execute:
/opt/rh/rh-php72/root/bin/pear upgrade-all
Add the php 7.2 repository:
For Debian Stretch
apt-get install wget apt-transport-https lsb-release ca-certificates
wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" >> /etc/apt/sources.list.d/php.list
apt-get update
For Ubuntu 18.04
It is necessary to add sudo in front of the following commands:
$ apt-get install software-properties-common
$ add-apt-repository ppa:ondrej/php
$ apt update
Install the following prerequisites:
apt-get install \
php7.2 \
php7.2-opcache \
libapache2-mod-php7.2 \
php7.2-mysql \
php7.2-curl \
php7.2-json \
php7.2-gd \
php7.2-mcrypt \
php7.2-intl \

lsb-release \
mariadb-server \
libconfig-inifiles-perl \
libcrypt-des-perl \
libdigest-hmac-perl \
libdigest-sha-perl \
libgd-perl
Activate the modules:
a2enmod proxy_fcgi setenvif proxy rewrite
a2enconf php7.2-fpm
a2dismod php7.2
systemctl restart apache2 php7.2-fpm
Additional commands are necessary to configure the environment correctly:
groupadd -g 6000 centreon
useradd -u 6000 -g centreon -m -r -d /var/lib/centreon -c "Centreon Admin" -s /bin/sh centreon
To finish, you should install SNMP MIBs. Because of a license problem the MIB files are not available by default in Debian. To add them, change the /etc/apt/sources.list file and add the non-free category.
Execute the following commands:
apt-get update
apt-get install snmp-mibs-downloader
Then modify the SNMP configuration file /etc/default/snmpd by adding:
export MIBDIRS=/usr/share/snmp/mibs
export MIBS=ALL
And commenting:
#mibs ALL
Restart SNMP service:
service snmpd restart
service snmptrapd restart

On some OpenSuse distributions, the default settings of the mine type are not valid to function with the Centreon web interface. Edit the /etc/mime.types file and find the lines:
text/x-xsl xsl
text/x-xslt xslt xsl
Replace them by:
text/xml xsl
text/xml xslt xsl
Save the file and restart Apache:
/etc/init.d/apache2 restart
Monitoring engine (Centreon Engine)
You can install it following the procedure in documentation. Don’t forget to install the Nagios plugins if you have not already done so.
Stream Multiplexer (Centreon Broker)
Install this Stream Multiplexers before continuing with the installation.
Centreon
Download the latest version of Centreon here.
Extract the Centreon archive:
tar zxf centreon-web-YY.MM.x.tar.gz
cd centreon-web-YY.MM.x
The installation script allows customized configuration; this process will show you the best paths to use. Furthermore quick yes/no questions can be replied to by [y] most of the time.
If centreon sources have been downloaded from github, run those commands:
composer install --no-dev --optimize-autoloader npm install npm run build
Run the installation script:
./install.sh -i

PHP dependencies installation
First, you need to install PHP dependency installer composer. Composer can be downloaded here (it is also available in EPEL repository).
Once composer is installed, go to the centreon directory (usually /usr/share/centreon/) and run the following command:
composer install --no-dev --optimize-autoloader
Javascript dependencies installation
First, you need to install javascript runtime nodejs. Installation instructions are available here.
Once nodejs is installed, copy the JSON files to the installation folder:
cp /usr/local/src/centreon-web-YY.MM.x/package* /usr/share/centreon/
Then go to the centreon directory (usually /usr/share/centreon/) and run the following commands:
npm install
npm run build
rm -rf node_modules
Any operating system
SELinux should be disabled; for this, you have to modify the file /etc/sysconfig/selinux and replace enforcing by disabled:
SELINUX=disabled
After saving the file, please reboot your operating system to apply the changes.
Timezone and mandatory PHP parameters have to be set: go to /etc/php/7.2/cli/conf.d or /etc/php/7.2/apache2/conf.d
directory and create a file named centreon.ini which contains the following lines:
date.timezone = Europe/Paris
max_execution_time = 300
session.use_strict_mode = 1
session.gc_maxlifetime = 7200
After saving the file, please don't forget to restart apache server.
The Mysql database server should be available to complete installation (locally or not). MariaDB is recommended.
After this step you should connect to Centreon to finalize the installation process.
Web installation
Conclude installation by performing web installation steps.
