Introduction

Zabbix is ​​an enterprise-level open source solution that provides distributed system monitoring and network monitoring capabilities based on a WEB interface.

Zabbix can monitor various network parameters to ensure the safe operation of the server system; and provide a flexible notification mechanism to allow system administrators to quickly locate/solve various existing problems.

Zabbix consists of two parts, Zabbix server and the optional component Zabbix agent.

Zabbix server can provide remote server/network status monitoring, data collection and other functions through SNMP, Zabbix agent, ping, port monitoring and other methods. It can run on Linux, Solaris, HP-UX, AIX, Free BSD, Open BSD, OS X and other platforms.

Similar products include Grafana, Nagios, Ganglia, Open-Falcon, etc.

Server Installation and Deployment

Refer to https://www.zabbix.com/download?zabbix=4.4&os_distribution=centos&os_version=8&db=mysql for installation and connection instructions

The latest Zabbix-4.4 version is installed here.

This experiment address description

Server: 192.168.143.130
Agent: 192.168.143.130,131

1. Choose a platform

Select the Zabbix version/OS type/OS version/Database type, etc.

Then different installation and connection instructions will be given according to the user's selection. Here we take Zabbix4.4, Centos7, MySQL database as an example.

2. Install according to the above selection

a. Install Zabbix source

rpm -Uvh https://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm #Load the source of zabbix yum clean all
ls /etc/yum.repos.d/
... zabbix.repo #Add this file

b. Install Zabbix server, frontend, agent

# yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-agent (zabbix components, may need to be executed multiple times due to network speed issues)

Error 1. Delta RPMs disabled because /usr/bin/applydeltarpm not installed.

This indicates that deltarpm is not installed. Run the command to view the package information.

yum provides '*/applydeltarpm' #Check the location of the dependent package, the prompt is as follows deltarpm-3.6-3.el7.x86_64: Create deltas between rpms #Prompts the package to be installed deltarpm-3.6-3.el7.x86_64
Repo: @base
Matched from:
Filename : /usr/bin/applydeltarpm

Execute the installation command

yum -y install deltarpm #安裝命令

If it still happens, it means that it is caused by network problems (the speed is too slow), then try multiple times (each time you download, the progress will increase and enter the cache)

c. Initialize the database and import the table structure

Initialize the database (MySQL version is 5.7)

create database zabbix character set utf8 collate utf8_bin;
CREATE USER 'zabbix'@'localhost' IDENTIFIED BY 'sj...sg';
CREATE USER 'zabbix'@'%' IDENTIFIED BY 'sj...sg';
GRANT ALL PRIVILEGES ON zabbix.* TO 'zabbix'@'%';
GRANT ALL PRIVILEGES ON zabbix.* TO 'zabbix'@localhost;

Importing data structures

# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

d. Modify the DB configuration file of zabbix server

vim /etc/zabbix/zabbix_server.conf
DBHost=192.168.143.130
DBPassword=xxx
DBPort=10306
DBSocket=/tmp/mysql.sock

e. Modify the PHP configuration file on the front end of the zabbix server

vim /etc/httpd/conf.d/zabbix.conf, uncomment and set the correct time zone (Asia/Shanghai)
php_value date.timezone Europe/Riga

f. Start the Zabbix server and Agent process. Set it to start automatically at boot.

Start the service

# systemctl restart zabbix-server zabbix-agent httpd

The actual call is

/usr/sbin/zabbix_server -c /etc/zabbix/zabbix_server.conf
/usr/sbin/zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf
/usr/sbin/httpd

Set up auto-startup

# systemctl enable zabbix-server zabbix-agent httpd

Process open port description

zabbix_agentd 10050
zabbix_server 10051
httpd 80

After the above steps, zabbix is ​​running.

Configure Zabbix frontend (frontend entry configuration)

http://192.168.143.130/zabbix
