Zabbix server setup - requirements

Revision as of 10:16, 27 October 2014 by WikiFreak (talk | contribs)


System installation

Requirements

You should already 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


Firewall script

See Firewall to get more details.


SNMP client

See SNMP client



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



Zabbix server # installation

Source: https://www.zabbix.com/documentation/2.2/manual/installation/install_from_packages


Add Zabbix repository

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


Install Zabbix server

apt-get install zabbix-server-mysql zabbix-frontend-php

# install Java Gateway too
apt-get install zabbix-java-gateway


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: 

apt-get install libnet-snmp-perl python-netsnmp


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 

vim /etc/apache2/conf-available/zabbix


Find the following lines and edit them as follows. If the lines doesn’t exists, add them. 

[...]
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
#php_value date.timezone Europe/Stockholm
[...]

Adjust your timezone !! To get the right value see: http://www.php.net//manual/en/timezones.php

Save and close the file.


Enable Apache2 V.Host

Last step: you have to enable Zabbix configuration 

cd /etc/apache2/conf-available/
a2enconf zabbix.conf
service apache2 reload



Restart zabbix server

To restart zabbix you have to restart 2 processes:

  • BACKEND: Zabbix-server
  • FRONTEND: Apache2


service apache2 restart
service zabbix-server restart


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
