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>
 
 
 
 
=Zabbix server # First run=
 
 
Now you can, at least, run the web-installer.
 
 
see [[Zabbix server configuration]]
 
 
 
 
 
=Zabbix agents=
 
 
Now you should configure your zabbix agents to use the current server. See [[Zabbix agent setup]]

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:

vim /etc/vim/vimrc

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
