zabbix monitoring system

1, zabbix overview

Zabbix is an enterprise class distributed open source monitoring solution.

Zabbix software can monitor the health and integrity of many network parameters and servers. Zabbix uses a flexible alarm mechanism that allows users to configure email based alarms for almost any event. This allows users to respond quickly to server problems. Zabbix provides excellent reporting and data visualization based on stored data. These features make Zabbix an ideal choice for capacity planning.

Zabbix supports active polling and passive capture (trapping). All Zabbix reports, statistics and configuration parameters can be accessed through the Web-based front-end page. The Web-based front-end page ensures that you can access the network status and server health you monitor anywhere. After proper configuration, Zabbix can play an important role in monitoring the IT infrastructure. Whether for a small number of users The same applies to small organizations with servers or large enterprises with a large number of servers.

2, zabbix function

zabbix distributed system monitoring

Zabbix is a highly mature and perfect network monitoring solution. A software package contains a variety of functions.

data acquisition

Availability and performance inspection;
Support SNMP (including active polling and passive capture), IPMI, JMX and VMware monitoring;
Custom check;
Collect the required data according to the user-defined time interval;
Perform data collection through Server/Proxy and Agents.

Flexible threshold definition

You can refer to the backend database to define a very flexible alarm threshold, that is, trigger

Highly configurable alarms

You can send alarm notification according to the increment plan, receiver and media type;

Using macro variables can make alarm notification more efficient and useful;

Automatic operations include remote execution commands.

Real time graphics

Using the built-in graphics function, the monitoring items can be drawn into graphics in real time.

Web monitoring function

Zabbix can track the click operation of the simulated mouse on the Web site to check the function and response time of the Web site.

3, zabbix build

//800 always_populate_raw_post_data = -1
//877 date.timezone = Asia/Shanghai

systemctl start php-fpm
systemctl enable php-fpm
netstat -natp | grep 9000

4. Test connection database

vim /usr/share/nginx/html/info.php


systemctl restart php-fpm.service
systemctl restart nginx

Real machine access

vim /usr/share/nginx/html/info.php
if ($link) echo 'Connection succeeded';
else echo 'connection failed';
==Real machine access==

mysql -uroot -p123456
create database zabbix character set utf8 collate utf8_bin;
grant all privileges on *.* to 'zabbix'@'%' identified by '123456';
flush privileges;
vim /usr/share/nginx/html/info.php
if ($link) echo 'zabbix success';
else echo 'zabbix fail';

==Real machine access==

5. Deploy zabbix server

rpm -i

#Multiple installations
yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent

cd /usr/share/doc/zabbix-server-mysql-4.0.32/
zcat create.sql.gz | mysql -uzabbix -p zabbix
mysql -u zabbix -p 123456
use zabbix;
show tables;

#Edit zabbix server configuration file
vim /etc/zabbix/zabbix_server.conf

#Define log file location and name
//38 LogFile=/var/log/zabbix/zabbix_server.log  

#Define the log file size. 0 means unlimited size
//49 LogFileSize=0

cp -r /usr/share/zabbix/ /usr/share/nginx/html
chown -R zabbix.zabbix /etc/zabbix
chown -R zabbix.zabbix /usr/share/nginx
chown -R zabbix.zabbix /usr/lib/zabbix
chmod -R 755 /etc/zabbix/web
chmod -R 777 /var/lib/php/session

systemctl start zabbix-server.service
systemctl enable zabbix-server.service

netstat -napl | grep 10051
systemctl restart php

==Real machine access==

Link: ZABBIX conf.php
Extraction code: yipx

cd /etc/zabbix/web
 Compressed package
chmod +x zabbix.conf.php
systemctl restart php-fpm.service
systemctl start zabbix-service.service
 Restart login

6. Configure proxy zabbix (

systemctl stop firewalld.service
setenforce 0

rpm -i

yum -y install zabbix-agent
vim /etc/zabbix/zabbix_agentd.conf
//98 Server= address to monitoring end
//139  ServerActive= pointing to the monitoring server
//150 Hostname=test modify hostname

systemctl start zabbix-agent.service
systemctl enable zabbix-agent.service
netstat -natp | grep 10050

7. Configure automatic email Publishing

First, select the mailbox and start the pop3 and smtp services
QQ mailbox opening mode

Configure on server


yum -y install mailx

vim /etc/mail.rc

#Last line add
set from=QQ
set smtp-auth-user=QQ
set smtp-auth-password=Authorization code
set smtp-auth=login

#Test whether it can be sent normally
echo 'hello wbw' | mail -s 'test' QQ
#Write the shell script for sending mail. Be sure to write it in this directory
cd /usr/lib/zabbix/alertscripts/

#send mail

messages=`echo $3 | tr '\r\n' '\n'`
subject=`echo $2 | tr '\r\n' '\n'`
echo "${messages}" | mail -s "${subject}" $1 >>/tmp/mailx.log 2>&1

#Create log file
touch /tmp/mailx.log

chown -R zabbix.zabbix  /tmp/mailx.log
chmod +x /usr/lib/zabbix/alertscripts/
chown -R zabbix.zabbix /usr/lib/zabbix/

#Test script
. /usr/lib/zabbix/alertscripts/ QQ "zabbix" "hello world"

8. Web page configuration monitoring mechanism


By default

Server restart zabbix service

systemctl restart zabbix-*

The proxy restarts the ssh service to see if the mail can be received

systemctl restart sshd
