| |
| − |
| |
| − |
| |
| − | Source: https://www.zabbix.com/documentation/2.2/manual/installation/install_from_packages
| |
| − |
| |
| − |
| |
| − |
| |
| − | ==Add Zabbix repository==
| |
| − |
| |
| − | <syntaxhighlight lang="bash">
| |
| − | wget http://repo.zabbix.com/zabbix/2.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_2.2-1+trusty_all.deb
| |
| − | dpkg -i zabbix-release_2.2-1+trusty_all.deb
| |
| − | apt-get update
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − |
| |
| − | ==Install Zabbix server==
| |
| − |
| |
| − | <syntaxhighlight lang="bash">
| |
| − | apt-get install zabbix-server-mysql zabbix-frontend-php
| |
| − |
| |
| − | # install Java Gateway too
| |
| − | apt-get install zabbix-java-gateway
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − |
| |
| − | During installation you have to set:
| |
| − | * MySQL administrator password
| |
| − | * Allow the automatic DB configuration: reply '''yes'' to "Configure DB for zabbix-server-mysql with dbconfig-common?"
| |
| − | * Enter your administrator password
| |
| − | * Set the MySQL zabbix password. As this will only be used inside a LAN (in my case) I put '''zabbix''' as password
| |
| − |
| |
| − |
| |
| − | The ''Zabbix server'' application will now use the MySQL login: '''zabbix''' and the password I set earlier ('''zabbix''').
| |
| − |
| |
| − |
| |
| − | -NOTE-
| |
| − |
| |
| − | Zabbix server also required some specific SNMP libraries:
| |
| − |
| |
| − | <syntaxhighlight lang="bash">
| |
| − | apt-get install libnet-snmp-perl python-netsnmp
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − |
| |
| − | ==Install zabbix-agent on zabbix-server==
| |
| − |
| |
| − | It's recommended to monitor your zabbix-server as well with the other servers. Therefore you should install a local ''zabbix-agent''.
| |
| − |
| |
| − |
| |
| − | See installation notes: [[Zabbix agent setup]]
| |
| − |
| |
| − |
| |
| − |
| |
| − | ==Allow remote connections to MySQL==
| |
| − |
| |
| − | See [[MySQL server]]
| |
| − |
| |
| − |
| |
| − |
| |
| − | ==Set timezone and PHP settings==
| |
| − |
| |
| − | Edit the configuration file
| |
| − |
| |
| − | <syntaxhighlight lang="bash">
| |
| − | vim /etc/apache2/conf.d/zabbix
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − |
| |
| − | Find the following lines and edit them as follows. If the lines doesn’t exists, add them.
| |
| − | <syntaxhighlight lang="bash">
| |
| − | [...]
| |
| − | php_value max_execution_time 300
| |
| − | php_value memory_limit 128M
| |
| − | php_value post_max_size 16M
| |
| − | php_value upload_max_filesize 2M
| |
| − | php_value max_input_time 300
| |
| − | php_value date.timezone Asia/Kolkata
| |
| − | [...]
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | Adjust your timezone !! To get the right value see: http://www.php.net//manual/en/timezones.php
| |
| − |
| |
| − | Save and close the file.
| |
| − |
| |
| − |
| |
| − | ==Set Apache2 V.Host==
| |
| − |
| |
| − | Last step: you have to copy this configuration to your local Apache2 server [zabbix has installed one for you].
| |
| − |
| |
| − | <syntaxhighlight lang="bash">
| |
| − | cp /etc/apache2/apache.conf /etc/apache2/conf-available/zabbix.conf
| |
| − | a2enconf zabbix.conf
| |
| − | service apache2 reload
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − |
| |
| − |
| |
| − | ==Restart zabbix server==
| |
| − |
| |
| − | To restart zabbix you have to restart 2 processes:
| |
| − | * BACKEND: Zabbix-server
| |
| − | * FRONTEND: Apache2
| |
| − |
| |
| − |
| |
| − | <syntaxhighlight lang="bash">
| |
| − | service apache2 restart
| |
| − | service zabbix-server restart
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − |
| |
