1. Introduction to zabbix
百度百科: Zabbix is an interface-based enterprise-level open source solution that WEBprovides distributed and network monitoring capabilities. 系统监视It is an enterprise-level highly integrated open source monitoring software, which can be used to monitor the availability and performance of equipment, servers, databases, etc., to ensure the 服务器系统safe operation of databases. And provide a flexible notification mechanism to 系统管理员quickly locate/solve various problems.
zabbix consists of 2 parts, zabbix server and optional component zabbix agent. It can provide monitoring of remote server/network status through methods such as SNMPzabbix agent, port monitoring, etc. It can run on Linux, Solaris, HP-UX, AIX, Free BSD, Open BSD, OS X and other platforms.ping数据收集

1. Zabbix deployment
1. Zabbix environment
| IP | CPU name | Role |
|---|---|---|
| 192.168.200.182 | zabbix_server | monitoring server |
| 192.168.200.183 | web001 | business host |
2. Install the zabbix installation package
Install zabbix_server
1. Set zabbix_server hostname
[root@zabbix_server ~]#hostnamectl set-hostname zabbix_server 或者 hostname zabbix_server #设置完成后需要退出终端然后重新打开，新的主机名就生效了
2. Turn off the firewall and selinux
[root@zabbix_server ~]# systemctl stop firewalld.service #停止防火墙服务
[root@zabbix_server ~]# systemctl disable firewalld.service
[root@zabbix_server ~]# setenforce 0 #临时关闭selinux
setenforce: SELinux is disabled
[root@zabbix_server selinux]# vim /etc/selinux/config #编辑配置文件为`SELINUX=disabled` 即可永久关闭selinux
3. Prepare zabbix-repo
4. Click download to jump here
5. Select the platform of your Zabbix server
6. Install the Zabbix package
- Install and configure Zabbix for your platform
[root@zabbix_server ~]# rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
获取https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
- Uninstall the rpm package
[root@zabbix_server ~]# yum remove -y zabbix-release.noarch
- The picture above is the official warehouse, the download speed is very slow, it is not recommended to use.
When foreign mirrors are not available, you can use the zabbixYUM source provided by Ali or other domestic YUM sources.
Enter the Ali mirror station address: https://developer.aliyun.com/mirror/?spm=a2c6h.25603864.0.0.3d501929Ml2fFi
pull down to find zabbix
- Configure zabbix YUM repository
[root@zabbix_server ~]# cd /etc/yum.repos.d
[root@zabbix_server yum.repos.d]# ls
CentOS-Base.repo CentOS-Base.repo.bak epel.repo epel-testing.repo vscode.repo zabbix.repo
[root@zabbix_server yum.repos.d]# vim zabbix.repo

8 Configure the database for Zabbix server
- Edit the configuration file /etc/zabbix/zabbix_server.conf
and remove the comments from the following configurations
[root@zabbix_server ~]# vim /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=123456
9 Configure PHP for Zabbix frontend
1. Edit the configuration file /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf uncomment and set the correct timezone for you.
[root@zabbix_server ~]# vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf
php_value[date.timezone] = Asia/Shanghai #只需将这行配置好就是行了，其它的不变

6.1 First backup, so as not to misuse /etc/yum.repos.d/CentOS-Base.repo
[root@web001 ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
Select the /etc/yum.repos.d/CentOS-Base.repo file of your corresponding version, and put it into /etc/yum.repos.d/ Please make a corresponding backup before operation
For example, your own centos version is 7, so use the content of version 7.
vim /etc/yum.repos.d/CentOS-Base.repo

# The mirror system uses the connecting IP address of the client and the

# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
