Zabbbix Self contained Item Enough to meet the monitoring needs of ordinary small companies , For large companies, you can also set custom Item, Automatically generate reports , Also have API Can be integrated with other systems .
Two 、 choice zabbix The advantages of
zabbix It can meet the requirements of the idealized monitoring system
● Support custom monitoring scripts , Provide the value to be output
●zabbix The stored database table structure is slightly complex, but the logic is clear
●zabbix There is Concept of template , It's convenient to put - Deploy group monitoring items ( For example, we have many zabbix Server side , If we were in a machine a It defines 100 Monitoring content , We're working on the machine b If so many monitoring contents need to be defined in, we don't need to redefine them , Just put the machine a Export the monitoring template of to the machine b Can )
●zabbix each individual item That is to say Monitoring item , You can see the history , And web Friendly interface
●zabbix Yes Powerful Trigger( trigger ) Define the rules , Complex alarm logic can be defined
●zabbix Provides ack Alarm acknowledgement mechanism

●zabbix_ proxy, proxy server
●zabbix_ database, The storage system ,mysql, pgsq|
●Zabbix_ web, web GUI Graphical interface

●Zabbix_ sender, Command line tools , Test direction server send data
●Zabbix_ java_ gateway, java gateway
Four 、zabbix Installation
zabbix The official download : download Zabbix
1、 Prepare a new machine , Environment initialization
zabbix The machine memory should be large enough ,4G Just fine .
Know the name of the device and take it out ip Address
Turn off firewall :
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
systemctl disable --now firewalld
selinux close , also iptables All three links allow data opening
2、 obtain zabbix Download source
rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
At Alibaba cloud's open source mirror zabbix5.0 Download the installation package
Once the download is complete , We can see in our repo There is one in the warehouse zabbix file
And then we vim Open this document , It is found that the default download path is zabbix official , That is, the Internet , Download too slow
So we need to zabbix.repo Source changed to Alibaba , use sed Command to replace the contents of the document
sed -i 's#http://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#' /etc/yum.repos.d/zabbix. repo
Then open the file here to check whether the modification is successful
And then modify zabbix-fronted Front end source , take 0 Change to 1
then yum clean all Empty the old yum cache
3、 download zabbix
yum install zabbix-server-mysql zabbix-agent -y
Installation tools , Multiple versions of software can be used on the machine , And it will not affect the dependent environment of the whole system .
yum install centos-release-scl -y
4、 install zabbix Front end environment
yum install zabbix-web-mysql-scl zabbix-apache-conf-scl -y( If it's installed scl Tools )
Generate the files in the following directory
5、 install zabbix The required database
Just use our own mariadb
yum install mariadb-server -y
6、 Configuration database , Boot up
systemctl enable --now mariadb
7、 Initialize database , Set the password
First, make sure that the database is turned on
systemctl status mariadb
netstat -tunlp Make sure 3306 Open port
Enter the command to start the initialization operation mysql_secure_installation
Then the following options will appear :

Third : Set your password .
Fourth : Enter the password you set again .
The fifth : Remove anonymous users ?# We choose Y, Remove him .
The sixth : prohibit root Remote login ?# We selected N, Convenient for testing .
The seventh : Whether to remove the test database and execute ?# We selected Y
The eighth : Whether to refresh the authorization table ?# We selected Y
Then enter the password to enter the database : mysql -uroot -p
8、 Add database users and zabbix Required database information
Access to database
And then create a zabbix database , Character encoding set to utf-8
create database zabbix character set utf8 collate utf_bin;
Create a zabbix User and set password
create user [email protected] identified bu 'chaoge666';
Authorize the user
grant all privileges on zabbix.* to [email protected];
Refresh authorization table flush privileges;
Exit database .
9、 Use zabbix-mysql Command to import database information
First, check whether the file exists
ls /usr/share/doc/zabbix-server-mysql*/create.sql.gz
Then use the command to import the compressed file into the database
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
#mysql -u user name -p( password ) zabbix( This zabbix It's not a code , But specified zabbix This library )
Enter the database to check whether the import is successful
use zabbix
show tables; Check whether the table is successful
10、 modify zabbix_server The configuration file , Change database password
Get into zabbix_server Configuration file for
In the document /DBpassword Find the line that needs to be modified
