We are showing how to configure gorgone to manage that architecture: ```text Central server <- Rebound server <- Distant Poller ``` In our case, we have the following configuration (need to adatp to your configuration). Central server: address: 10.30.2.203 Rebound server: id: 1024 (It must be unique. It's an arbitrary number) address: 10.30.2.67 rsa public key thumbprint: NmnPME43IoWpkQoam6CLnrI5hjmdq6Kq8QMUCCg-F4g Distant Poller: id: 6 (configured in Centreon interface as zmq*. You get it in the Centreon interface) address: 10.30.2.179 rsa public key thumbprint: nJSH9nZN2ugQeksHif7Jtv19RQA58yjxfX-Cpnhx09s The Distant Poller is already installed and Gorgone also. We configure the file /etc/centreon-gorgone/config.d/40-gorgoned.yaml: ```yaml name: distant-server description: Configuration for distant server gorgone: gorgonecore: id: 6 privkey: "/var/lib/centreon-gorgone/.keys/rsakey.priv.pem" pubkey: "/var/lib/centreon-gorgone/.keys/rsakey.pub.pem" modules: name: action package: gorgone::modules::core::action::hooks enable: true command_timeout: 30 whitelist_cmds: true allowed_cmds: ^sudo\s+(/bin/)?systemctl\s+(reload|restart)\s+(centengine|centreontrapd|cbd)\s*$ ^(sudo\s+)?(/usr/bin/)?service\s+(centengine|centreontrapd|cbd|cbd-sql)\s+(reload|restart)\s*$ ^/usr/sbin/centenginestats\s+-c\s+/etc/centreon-engine/centengine\.cfg\s*$ ^cat\s+/var/lib/centreon-engine/[a-zA-Z0-9\-]+-stats\.json\s*$ ^/usr/lib/centreon/plugins/.*$ ^/bin/perl /usr/share/centreon/bin/anomalydetection --seasonality >> /var/log/centreon/anomalydetection\.log 2>&1\s*$ ^/usr/bin/php -q /usr/share/centreon/cron/centreon-helios\.php >> /var/log/centreon-helios\.log 2>&1\s*$ ^centreon ^mkdir ^/usr/share/centreon/www/modules/centreon-autodiscovery-server/script/runsavediscovered_host ^/usr/share/centreon/bin/centreon -u \"centreon-gorgone\" -p \S+ -w -o CentreonWorker -a processQueue$ name: engine package: gorgone::modules::centreon::engine::hooks enable: true command_file: "/var/lib/centreon-engine/rw/centengine.cmd" name: pull package: "gorgone::modules::core::pull::hooks" enable: true target_type: tcp target_path: 10.30.2.67:5556 ping: 1 ``` We have installed a CentOS 7 server. We install Gorgone daemon: ```shell yum install http://yum.centreon.com/standard/20.04/el7/stable/noarch/RPMS/centreon-release-20.04-1.el7.centos.noarch.rpm yum install centreon-gorgone ``` We configure the file /etc/centreon-gorgone/config.d/40-gorgoned.yaml: ```yaml name: rebound-server description: Configuration for rebound-server gorgone: gorgonecore: id: 1024 privkey: "/var/lib/centreon-gorgone/.keys/rsakey.priv.pem" pubkey: "/var/lib/centreon-gorgone/.keys/rsakey.pub.pem" externalcomtype: tcp externalcompath: "*:5556" authorized_clients: key: nJSH9nZN2ugQeksHif7Jtv19RQA58yjxfX-Cpnhx09s modules: name: proxy package: "gorgone::modules::core::proxy::hooks" enable: true name: pull package: "gorgone::modules::core::pull::hooks" enable: true target_type: tcp target_path: 10.30.2.203:5556 ping: 1 ``` The Central server is already installed and Gorgone also.
