Zabbix server setup - requirements
Contents
System installation
Requirements
You should already have:
- DNS server
- DHCP server
- Internet access
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/vimrcEnable 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.d/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
[...]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].
cp /etc/apache2/apache.conf /etc/apache2/conf-available/zabbix.conf
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 # Web installer
Now you can, at least, run the web-installer.
Go to http://yourserver/zabbix
Installation
Welcome screen:
Installation check:
Database configuration:
During the installation Zabbix already setup a database for us! :)
- Db host: localhost
- Db Port: 3306 (default)
- Db name: zabbix
- Db user: zabbix
- Db password: your password (mine is zabbix)
Zabbix server details
You can, if you want, name your installation. In my case I will not have any proxy or other zabbix server so I didn't used that option.
Confirmation
First login
Default credentials are:
- Username = Admin
- Password = zabbix
Notice the big 'A' for Admin.
Zabbix agents
Now you should configure your zabbix agents to use the current server. See Zabbix agent setup
Zabbix server configuration
Login to your zabbix server: http://myServer/zabbix
Add host
You have to had a host (= machine with a zabbix agent) on the server side in order to monitor it.
1. Go to the Configuration > "Add host" menu
- Click on Configuration Menu
- Click on Hosts submenu
- Click on Create Host button at right side
2. Now fill the following details of remote host
- Hostname: Hostname of Remote system
- Visible name: Name to be display in zabbix
- Group: Select the desired group for you host
- You should use Linux at least
- You can create your own groups and classification as well
- Agent interface: Fill the info of Zabbix agent running on host
- Select the DNS option instead of IP. So if we move the client for any reason that will NOT impact the monitoring. :)
- Status: Select initial status
IMPORTANT !! The name of the hostname must match the real hostname - as return by the `hostname` command !!
3. Set some monitoring templates to apply
Click on the "Templates" tab
To get the list of templates, just type template in the search area. Select, at least:
- Template OS Linux
- (if your client is NOT a Linux) Template Zabbix agent
Don't forget to click the "ADD" button!
The Linux OS includes the Zabbix agent template. :)
4. Automatic host inventory
Click on the "host inventory" tab
Enable the Automatic option. Click "save" at the bottom of the page.
Setup host discovery
Discovery settings
Go to menu Configuration > Discovery, then click on "Local Network". Fill the form:
- Set the correct LAN settings
- Adjust the time from 3600 to 900 (check every 15 minutes)
- Enable the following Checks:
- ICMP ping
- zabbix agent
- SSH
- SNMP with the following params:
- version: SNMPv2
- port range: 161 (default)
- community: vehco
- SNMP OID: SNMPv2-MIB::sysName.0
- Use a search by IP @ filter
- Enable discovery
Create actions
Go to menu Configuration > Actions
1. Select the actions' group Discovery:
2. Edit the Auto discovery. Linux server action:
- Enable the action
On the "configuration" tab...
Add a "Host IP" filter with your correct LAN as a 4th filter
View Graph in Zabbix
Graphs are always attracted the new users, Below screenshot will help you to how to view graphs in zabbix. If you have just added the host, you need to wait for few time, so that zabbix can collect some data from remote host to show on graph.
