最近部署Zabbix发现网上很多的资料都是过期的，不适合现在的环境。后来经过不断的查找资料，按照本文的步骤，搭建成功。本文用详细的图文资料将所有步骤记录下来，方便后期查阅。

一、 CentOS8.5操作系统初始环境准备

Centos8于2021年年底停止了服务，在使用yum源安装时候会出现下面错误

错误：Failed to download metadata for repo ‘AppStream’: Cannot prepare internal mirrorlist: No URLs in mirrorlist”

解决办法

1、替换成vault源

cd /etc/yum.repos.d/
sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*

2、更新yum源为阿里云镜像源

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
yum clean all
yum makecache

二、安装MySQL8.0

dnf install mysql-server

vim /etc/my.cnf.d/charset.cnf
cat /etc/my.cnf.d/charset.cnf
# set default charaset
# for the case of 4 bytes UTF-8, specify [utf8mb4]
[mysqld]
character-set-server = utf8mb4

systemctl enable --now mysqld

systemctl restart mysqld
mysql_secure_installation

设置MySQL root用户可以远程登录

firewall-cmd --add-service=mysql --permanent
firewall-cmd --reload

mysql -uroot -p -h 127.0.0.1
use mysql;
update user set host= '%' where user = 'root';
flush privileges;

三、安装Zabbix6.0

rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-6.0-1.el8.noarch.rpm
dnf install zabbix-server-mysql zabbix-web-mysql zabbix-nginx-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent

四、zabbix数据库初始化

mysql -uroot -p
create database zabbix character set utf8mb4 collate utf8mb4_bin;
create user zabbix@'%' identified by 'Zabbix@2022';
grant all privileges on zabbix.* to zabbix@'%';

zcat /usr/share/doc/zabbix-sql-scripts/mysql/server.sql.gz | mysql -uzabbix -p zabbix

vim /etc/zabbix/zabbix_server.conf 


#配置文件中填入数据库密码
DBPassword= Zabbix@2022

cat /etc/zabbix/zabbix_server.conf | grep DBPassword

五、启动Zabbix-Server及相关组件

1、编辑配置文件 /etc/nginx/conf.d/zabbix.conf, 取消如下两行的注释

vi /etc/nginx/conf.d/zabbix.conf 
         listen          80;
#        server_name     zabbix.walkingcloud.cn;

2、/etc/nginx/nginx.conf 中下面一段注释掉后重启nginx服务

server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;
        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;
        location / {
        }
        error_page 404 /404.html;
            location = /40x.html {
        }
        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
