| |

| |
| − | ==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>

This page describe the server requirements to install Zabbix monitoring.
You can skip that part if you already have a running server.
Requirements
You network must contain | provide:
The server must have:
O.S installation
On dedicated hardware you need to install Ubuntu Server 14.04 LTS using an USB key.
System configuration
Update sources.list and install key packages
Edit your sources.list
apt-get install vim
vim /etc/apt/sources.list
Put the following:
### Custom repositories list
#
# May 2014 - Guillaume Diaz
# This is an ajdustement of the default "debootstrap" sources.list
# This is required to provided update, security and advanced tools to all our clients
#
#########################
# Ubuntu 14.04 LTS [Trusty]
#########################
# Official repositories
deb http://se.archive.ubuntu.com/ubuntu/ trusty main restricted universe multiverse
deb http://se.archive.ubuntu.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu trusty-security main restricted universe multiverse
# Official updates
deb http://se.archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse
# Canonical partners
#deb http://archive.canonical.com/ubuntu trusty partner
# Community partners
#deb http://extras.ubuntu.com/ubuntu trusty main
Update your package list:
apt-get update && apt-get upgrade
Linux utilities
Now, you can install the basic programs:
# NFS is a bit low, and if you're using many client it might result in time faults.
# You must install NTP to overcome this !!
apt-get install ntp ntpdate
# Basic set of utilities
apt-get install unzip zip htop python3 sysv-rc-conf mc
# Network tools
apt-get install curl
# Advanced APT manager (require to add repository from command line)
apt-get install software-properties-common python-software-properties
# SSH server
apt-get install openssh-server openssh-client
Adjust bash and vim configuration
Edit your VIM configuration:
Enable dark background + set nu + set ruler
Edit your bash configuration files to adjust the alias and enable auto-completion:
vim /etc/bash.bashrc
vim /home/<username>/.bashrc
vim /root/.bashrc
Setup network interfaces
Even though you're using the NetBoot process you still have to register some interfaces! More important, the NetBoot disable the loopback "lo" - so you should better add that one back!
# Adjust "xxxx" by your distribution name
vim /etc/network/interfaces
Add:
auto lo
iface lo inet loopback
# Ethernet default interface
auto eth0
iface eth0 inet dhcp
# Intel NUC ethernet interface is named em1
auto em1
iface em1 inet dhcp
