Zabbix Server Deployment

Zabbix Introduction

Zabbix is an enterprise-class open source solution that provides distributed system monitoring and network monitoring capabilities based on a web interface

The Zabbix consists of the Zabbix server and the optional Component Zabbix Agent two departments.

Zabbix server can provide monitoring of remote server/network status through Snmp,zabbix agent,ping, port monitoring, and other methods.

The Zabbix agent needs to be installed on the target server being monitored, and it mainly completes the collection of information such as hardware information or operating system-related memory, CPU, etc.

Main functions:

CPU load, memory usage, disk usage, network condition, port monitoring, log monitoring

Zabbix is comprised of two parts, Zabbix server and Zabbix agent

Zabbix support A lot of monitoring methods, agent,agent active, simple monitoring, SNMP,SNMP trap and so on

Item-iterm defines the items of the monitored data, such as the memory usage of the host being monitored

Collection-application defines the summary of some items, the relationship of directories and files

Trigger-trigger determine the definition of host State by the data obtained by the project

Image-graph The data obtained by the project and displayed graphically

Template-template to summarize items, collections, triggers, graphs into a template, directly linked to a class of hosts for batch definition

Host-host monitored objects, servers or other network devices

Host group-host Group A class of hosts can be defined to a primary group

Action-action trigger Auto-discovery or auto-registration state change triggered action

Auto-discovery-discovery Add monitoring hosts in bulk by defining auto-discovery conditions and combining actions

Autoenrollment-auto-registration Agent sends registration requests to server, server definition autoenrollment Add bulk add main clause

Low-level Autodiscover (low_discovery): A case where a type has multiple items can be simply defined by low-level Autodiscover

For example, the disk capacity monitoring, usually the disk will have multiple partitions, we can use a definition to monitor the disk all partitions on the

Maintenance (maintenace): Define when a host is in maintenance state

topology map: Direct topology of hosts

screen (screents): Multiple types displayed in a screent

IT Services (IT service): Sometimes a host outage may not affect the service, IT service defines the limits of service tolerance degree

Instrument panel (dashboard): Monitor the overall status display

Overview (Overview): Displays data or trigger status for all machines

Web: Monitoring Web servers by defining scenarios

Latest data: View the latest data from the host project

Event: Record of change in trigger state

Zabbix Server Installation

First, install the dependency package

Yum install gcc net-snmp-devel curl-devel perl-dbi php-gd php-mysql php-bcmath php-mbstring php-xm *gettext* *gd* *libpng * *freetype* *libgpeg* Gd-devel mysql-devel

Second, server-side deployment

1. Installing the Database

MySQL installation here is slightly ....

Deploy the MySQL database and set up the appropriate Zabbix user

CREATE database Zabbix character set UTF8;

Grant all on zabbix.* to [email protected] '% ' identified by ' zabbixpass ';

Flush privileges;

2. Installing Apache

Apache installation here is slightly ...

3. Compiling and installing PHP

When deploying zabbix2.4, the following PHP environments are required

PHP version 5.3.0 above, GD library in more than 2.0, libxml 2.6 or more; Zabbix need gettext.so and bcmath.so two modules

./configure--prefix=/usr/local/php \ PHP installation directory

--WITH-APXS2=/USR/LOCAL/APACHE/BIN/APXS \ Apache Extension Plugin

--WITH-LIBXML-DIR=/USR/LOCAL/LIBXML2 \ libxml2 is an XML C-language parser that supports not only C language, but also C + + PHP Ruby, etc.

--enable-sockets \ Support Socket

--WITH-MYSQL=MYSQLND \ Mysqlnd is a PHP extension that uses the PHP memory management system, which is quite efficient in terms of memory usage

--WITH-MYSQLI \ PHP Connection Database module

--WITH-GETTEXT=/USR/LIB64 \ GetText Module

--enable-bcmath \ Math Function Module

--enable-mbstring \ mbstring Library, string function module, solve the problem of coding

--WITH-PNG-DIR=/USR/LIB64 \ PNG Picture format

--WITH-JPEG-DIR=/USR/LIB64 \ JPEG Picture format

--with-freetype-dir=/usr/lib64 \ Font

--WITH-GD=/USR/LOCAL/GD \ GD is an open source image processing library that supports images in png/jpeg/gif and other formats.

GD is typically used to create graphs, graphs, thumbnails, and other image-related processing operations

Make && make install

Add php.ini File

CP Php.ini-development/usr/local/php/lib/php.ini

Modify PHP Related parameters

Vim php.ini

Max_execution_time = 300

Max_input_time = 300

Memory_limit = 128M

Post_max_size = 32M

Date.timezone = Asia/shanghai

Note: The GD library needs to be deployed separately, downloaded and then compiled and installed (the location of the test installation is/USR/LOCAL/GD)

4. Installing the Zabbix Software

A. Adding Zabbix users

ID Zabbix && groupadd zabbix && useradd Zabbix | | echo "Zabbix is exist!"

B. Download the package

wget http://nchc.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/2.4.6/zabbix-2.4.6.tar.gz

C. Import initial data: Install sequential Import

Mysql-uroot-p Zabbix <schema.sql

Mysql-uroot-p Zabbix <images.sql

mysql-uroot-p Zabbix <data.sql

d. Compiling the installation

./configure \

--prefix=/usr/local/zabbix \

--with-mysql \ Use MySQL to do database server

--with-net-snmp \ Support SNMP

--with-libcurl \ Support curl, user Web monitoring

--enable-server \ Installing Zabbix server

--enable-agent \ Install Zabbix agent

--enable-proxy Installing Zabbix proxy

Make && make install

5. Modify the configuration file

Vim/usr/local/zabbix/etc/zabbix_server.conf

Logfile=/tmp/zabbix_server.log//log file location

dbhost=127.0.0.1//Database IP

Dbname=zabbix//Database

Dbuser=zabbix//user

Dbpassword=zabbixpass//password

dbport=3306//Database Password

listenip=192.168.36.130//zabbix listening IP, default listening port 10051

Vim/usr/local/zabbix/etc/zabbix_agentd.conf

Logfile=/tmp/zabbix_agentd.log//log file location

server=192.168.36.130//zabbix Server IP

serveractive=192.168.36.130//Open Active monitoring

HOSTNAME=SLAVE30 host name or IP on//agent side

Enableremotecommands=1//Allow remote command execution

6. Configure the Zabbix paging file by defining a new virtual host or by using alias aliases

CD zabbix-2.203/frontends/

CP-RF Php/home/httpd/zabbix #虚拟主机目录

7. The client browses the Http://IP/zabbix and then installs the prompt to step through the installation action

8. Start Zabbix

/usr/local/zabbix/sbin/zabbix_server//Start server side

/USR/LOCAL/ZABBIX/SBIN/ZABBIX_AGENTD//Start Client

9.NETSTAT-UNLTP | grep Zabbix//See if it starts

10. Add a startup script

Enter the Zabbix source directory under MISC/INIT.D to select the appropriate system

CP zabbix_agentd/etc/init.d/

CP zabbix_server/etc/init.d/

chmod +x zabbix*

11. Modify the page display font

You can replace the Zabbix font with the new C:\Windows\Fonts on Win7

[[Email protected]_server ~]# cd/var/www/zabbix/php/fonts//zabbix page file directory

[[Email protected]_server fonts]# ls

Dejavusans.ttf_bak Simsunb.ttf

[Email protected]_server fonts]# MV Simsunb.ttf Dejavusans.ttf

Problem

1.configure:error:not found Mysqlclient library

Workaround: Yum Install Mysql-devel

2.configure:error:unable to find LIBGD. (A|SO) >= 2.1.0 anywhere UNDER/USR/LOCAL/GD2

Workaround: Install gd2.1.1 or above and specify the installation directory of GD when compiling PHP

3. Garbled characters appear in the report

Workaround: Remove the "Chinese italic" file from C:\Windows\Fonts into the/var/www/zabbix/php/fonts (Zabbix's page file directory)

the name of the font Stkaiti.ttf

Cd/var/www/zabbix/php/include

Sed-i ' s/dejavusans/ stkaiti/g ' defines.inc.php

4.Zabbix Discoverer processes more than 75% busy use Zabbix when the discovery function is turned on, there is this alarm!

Workaround:

Cat zabbix_server.conf | Grep-ni startdiscoverers

166:### option:startdiscoverers

172:startdiscoverers=5 # #原来为1, modified to 5, the problem can be resolved, specific changes to how much, according to their own system performance to determine

5. Cannot explore the item, can be deleted in the database, find the Ts_delete field of the Item_discovery table is not 0 row

Use zabbix;delete from item_discovery where ts_delete>0;

6. What is the difference between configuration files zabbix_agent.conf and zabbix_agentd.conf?

zabbix_agent.conf is launched in a super-service (XINETD) manner .

zabbix_agentd.conf is initiated in a way that is independent of the process.
