CentOS8.5下安装部署开源监控系统Zabbix 6.0LTS

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

截图略

下面参考Zabbix官方安装向导说明文档进行安装部署

二、安装MySQL8.0

dnf install mysql-server

(图片可点击放大查看)

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;

最后验证远程登录

mysql -uroot -p -h 192.168.31.47

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@'%';

(图片可点击放大查看)

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

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


#配置文件中填入数据库密码
DBPassword= Zabbix@2022

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 {
        }
    }

3、启动服务

systemctl restart zabbix-server zabbix-agent nginx php-fpm
systemctl enable zabbix-server zabbix-agent nginx php-fpm
firewall-cmd --permanent --zone=public --add-port=80/tcp
firewall-cmd --permanent --zone=public --add-port=10051/tcp
firewall-cmd --permanent --zone=public --add-port=10050/tcp
firewall-cmd --reload
