0 卸载 Zabbix

yum remove -y $(yum list installed | grep zabbix | awk '{print $1}')

1 准备工作

1.1 关闭防火墙

sudo systemctl stop firewalld.service
sudo systemctl disable firewalld.service

1.2 关闭SELinux

sudo vim /etc/selinux/config

SELINUX = disabled

1.3 重启服务器

sudo reboot

1.4 安装MySQL

2 配置 Zabbix yum 源

阿里云镜像

https://mirrors.aliyun.com/zabbix/zabbix

2.1 安装zabbix的软件仓库配置包

sudo rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
sudo yum clean all

2.2 安装 Software Collections 仓库

sudo yum install -y centos-release-scl

/etc/yum.repo.d/CentOS-SCLo-scl-rh.repo

# CentOS-SCLo-rh.repo
#
# Please see http://wiki.centos.org/SpecialInterestGroup/SCLo for more
# information

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-SCLo

2.3 修改 Zabbix 仓库配置文件

查看原始zabbix.repo文件

sudo cat /etc/yum.repos.d/zabbix.repo

全改为阿里云的镜像

sudo sed -i 's/http:\/\/repo.zabbix.com/https:\/\/mirrors.aliyun.com\/zabbix/g' /etc/yum.repos.d/zabbix.repo

打开 /etc/yum.repos.d/zabbix.repo 文件，启用zabbix-web仓库

vim /etc/yum.repos.d/zabbix.repo

[zabbix-frontend] 中的 enabled=0改为 enabled = 1

最终的zabbix.repo

[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/$basearch/
enabled=1
gpgcheck=1

3 安装 Zabbix

sudo yum install -y zabbix-server-mysql zabbix-agent zabbix-web-mysql-scl zabbix-apache-conf-scl

3.1 遇到报错Requires: libmysqlclient.so.18

Error: Package: zabbix6.0-server-mysql-6.0.29-1.el7.x86_64 (epel)
           Requires: libmysqlclient.so.18(libmysqlclient_18)(64bit)
Error: Package: zabbix6.0-server-mysql-6.0.29-1.el7.x86_64 (epel)
           Requires: libmysqlclient.so.18()(64bit)
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

原因可能是安装MySQL时没有安装mysql-community-embedded-compat-8.0.36-1.el7.x86_64.rpm，这个软件包提供了 MySQL 8.0 与早期版本的 MySQL 和 MariaDB 之间的兼容性库。

解决办法：

rpm -ivh mysql-community-libs-compat-8.0.36-1.el7.x86_64.rpm

3.2 遇到报错 Requires: rh-php72

Error: Package: zabbix-web-deps-scl-5.0.6-1.el7.noarch (zabbix-frontend)
Requires: rh-php72-php-gd
Error: Package: zabbix-web-deps-scl-5.0.6-1.el7.noarch (zabbix-frontend)

Requires: rh-php72
Error: Package: zabbix-web-mysql-scl-5.0.6-1.el7.noarch (zabbix-frontend)
Requires: rh-php72-php-mysqlnd

解决办法

# 1. 卸载旧PHP
yum remove php* -y

# 2. 安装rh
yum install centos-release-scl-rh

# 3. 查询php
yum search php

# 4.安装
yum -y install rh-php72
scl enable rh-php72 bash

# 5.查看版本
php -v

4 配置 Zabbix

4.1 创建 zbbix 数据库

mysql -uroot -p123456
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user zabbix@localhost identified by '123456';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> set global log_bin_trust_function_creators = 1;
mysql> quit;

4.2 导入 zabbix 建表语句

zcat /usr/share/doc/zabbix-server-mysql-5.0.42/create.sql.gz | mysql -uroot -p123456 zabbix

导入数据库架构后禁用log_bin_trust_function_creators选项。

mysql -uroot -p123456 -e"set global log_bin_trust_function_creators = 0;"

4.3 配置 zabbix-server

sudo vim /etc/zabbix/zabbix_server.conf

DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=123456

4.4 配置 zabbix-agent

sudo vim /etc/zabbix/zabbix_agentd.conf

Server=centos702
# ServerActive=127.0.0.1
# Hostname=Zabbix server

4.5 配置zabbix-web时区

sudo vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf

php_value[date.timezone] = Asia/Shanghai

5 启动、停止 Zabbix

5.1 zabbix-agent

开机自启

systemctl enable zabbix-server httpd rh-php72-php-fpm

启动

systemctl restart zabbix-server httpd rh-php72-php-fpm

停止

systemctl stop zabbix-server httpd rh-php72-php-fpm

5.1.1 启动报错 Can’t open PID file

Can't open PID file /run/zabbix/zabbix_server.pid (yet?) after start: No such file or directory

查看日志

tail -n 100 /var/log/zabbix/zabbix_server.log

2091:20240621:133938.283 [Z3001] connection to database 'zabbix' failed: [2059] Authentication plugin 'caching_sha2_password' cannot be loaded: /usr/lib64/mysql/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory
  2091:20240621:133938.283 Cannot connect to the database. Exiting...

这个错误通常发生在尝试连接MySQL数据库时，特别是当数据库服务器使用的是MySQL 8.0及以上版本，因为从MySQL 8.0开始，默认的用户密码认证插件变成了'caching_sha2_password'。而你尝试使用的客户端或连接库可能还没有更新来支持这个新的认证插件。

解决办法

mysql -uroot -p123456 -e"ALTER USER 'zabbix'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';"
mysql -uroot -p123456 -e"FLUSH PRIVILEGES;"
