Using sources¶
Prerequisites¶
CentOS¶
Most CentOS users will find easier to install Centreon Web by using packages provided by Centreon.
CentOS and RHEL environments do not possess as standard on archives all the dependencies necessary for the installation of Centreon. You should add the RPM Forge and Software Collections repositories.
el7 system:
$ wget http://repository.it4i.cz/mirrors/repoforge/redhat/el7/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.3-1.el7.rf.x86_64.rpm
$ wget https://repository.it4i.cz/mirrors/repoforge/RPM-GPG-KEY.dag.txt
Use your favorite text editor and delete the first line of the RPM-GPG-KEY.dag.txt file. The first line should contain:
"-----BEGIN PGP PUBLIC KEY BLOCK-----"
Then perform the following commands:
$ rpm --import RPM-GPG-KEY.dag.txt
$ rpm -Uvh rpmforge-release-0.5.3-1.el7.rf.x86_64.rpm
$ yum install centos-release-scl
You can now install the necessary prerequisites:
$ yum update
$ yum upgrade
$ yum install httpd24-httpd gd fontconfig-devel libjpeg-devel libpng-devel gd-devel perl-GD perl-DateTime \
openssl-devel perl-DBD-MySQL mysql-server mysql-devel rh-php71-php rh-php71-php-mysql rh-php71-php-gd \
rh-php71-php-ldap rh-php71-php-xml rh-php71-php-mbstring rh-php71-php-snmp \
perl-Config-IniFiles 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 perl-Net-SNMP net-snmp-perl fping cpp gcc gcc-c++ libstdc++ glib2-devel \
rh-php71-php-pear nagios-plugins
Additional commands are necessary to configure the environment correctly:
$ usermod -U apache
$ 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:
$ pear config-set http_proxy http://my_proxy.com:port
Then execute:
$ pear upgrade-all
Debian Stretch / Ubuntu 18.04¶
Add the php 7.1 repository: For Debian Stretch:
$ apt-get install 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:
Note
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 php7.1 php7.1-opcache libapache2-mod-php7.1 php7.1-mysql php7.1-curl php7.1-json \
php7.1-gd php7.1-mcrypt php7.1-intl php7.1-mbstring php7.1-xml php7.1-zip php7.1-fpm php7.1-readline \
php7.1-sqlite3 php-pear sudo tofrodos bsd-mailx lsb-release mariadb-server libconfig-inifiles-perl \
libcrypt-des-perl libdigest-hmac-perl libdigest-sha-perl libgd-perl php7.1-ldap php7.1-snmp php-db php-date
Activate the modules:
$ a2enmod proxy_fcgi setenvif proxy rewrite
$ a2enconf php7.1-fpm
$ a2dismod php7.1
$ systemctl restart apache2 php7.1-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/bash 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
Suse¶
Packages¶
Install the following prerequisites:
$ yast -i gcc gcc-c++ make automake apache2 php5 php5-mysql apache2-mod_php5 php5-pear \
php5-ldap php5-snmp php5-gd php5-soap php5-intl php5-posix php5-gettext php5-mbstring mysql \
libmysqlclient-devel perl-DBD-mysql mysql-community-server rrdtool perl-Config-IniFiles \
net-snmp perl-Net-SNMP perl-SNMP gd libjpeg-devel libpng-devel fontconfig-devel \
freetype2-devel sudo mailx fping iputils dos2unix cron dejavu nagios-plugins
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 is tested and approved only for the 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 is tested and approved only for the stream multiplexer Centreon Broker.
Install this Stream Multiplexers before continuing with the installation.
Warning
Centreon Web is not compatible with Nagios monitoring engine.

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
Macro modifications¶
Macros may not have been properly replaced. Run the following commands to correct their values:
$ sed -i -e 's/_CENTREON_PATH_PLACEHOLDER_/centreon/g' /usr/share/centreon/www/index.html
$ sed -i -e 's/@PHP_BIN@/\/usr\/bin\/php/g' /usr/share/centreon/bin/centreon
$ sed -i -e 's/@PHP_BIN@/\/usr\/bin\/php/g' /usr/share/centreon/bin/export-mysql-indexes
$ sed -i -e 's/@PHP_BIN@/\/usr\/bin\/php/g' /usr/share/centreon/bin/generateSqlLite
$ sed -i -e 's/@PHP_BIN@/\/usr\/bin\/php/g' /usr/share/centreon/bin/import-mysql-indexes
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/7.1/cli/conf.d or /etc/php/7.1/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.
Configuration¶
Note
To get the IP address of your Centreon server, uses the command:
# ip addr
Log in to Centreon web interface via the URL: http://[SERVER_IP]/centreon. The Centreon setup wizard is displayed. Click on Next.
The Centreon setup wizard checks the availability of the modules. Click on Next.
Click on Next.
Click on Next.
Provide the information on the admin user, then click on Next.
By default, the localhost server is defined and the root password is empty. If you use a remote database server, change these entries. In this case, you only need to define a password for the user accessing the Centreon databases, i.e., Centreon. Click on Next.
Note
If the “Add innodb_file_per_table=1 in my.cnf file under the [mysqld] section and restart MySQL Server.” error message appears, perform the following operations:
Log in to the root user on your server.
Modify this file:
/etc/my.cnf
Add these lines to the file:
[mysqld] innodb_file_per_table=1
Restart the mysql service:
# systemctl restart mysqlClick on Refresh.
Note
If you use a deported MySQL v8.x DBMS, you may have the following error message: error. Please have a look to this procedure to solve this issue.
The Centreon setup wizard configures the databases. Click on Next.
You will now be able to install the Centreon server modules.
Click on Install.
Once installation is complete, click on Next.
At this point, an advertisement informs you of the latest Centreon news and products. If your platform is connected to the internet, the information you receive will be up to date. If you are not online, only information on the current version will be displayed.
The installation is complete. Click on Finish.
You can now log in.
