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-common \
rh-php72-php-pdo \
rh-php72-php-intl \
rh-php72-php-pear \
rh-php72-php-json \
rh-php72-php-mysqlnd \
rh-php72-php-ldap \
rh-php72-php-gd \
rh-php72-php-cli \
rh-php72-php-mbstring \
rh-php72-php-snmp \
openssl \
perl-DBD-MySQL \
perl-Sys-Syslog \
httpd24-httpd \
perl-DBI \
perl-DBD-MySQL \
rrdtool \
perl-rrdtool \
perl-Crypt-DES \
perl-Digest-SHA1 \
perl-Digest-HMAC \
net-snmp-utils \
perl-Socket6 \
perl-IO-Socket-INET6 \
net-snmp \
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

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

Prerequisites check

If the Prerequisites installation step has been run successfully you should have no problem during this stage. Otherwise repeat the Prerequisites installation process:

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.
