前言

zabbix可以用来监控MySQL数据库可用性和性能，保证数据库的安全运营。并提供灵活的通知机制快速定位/解决存在的各种问题。

⛳️ 1.部署Zabbix服务器

1.zabbix镜像下载
docker pull techerwang/dbhub:jemzabbix62

2.创建一个新的bridge网络
[root@jeames ~]# docker network create --driver bridge --subnet=172.18.12.0/16 --gateway=172.18.1.1 mynet3.创建容器
dockerrm -f jemzabbix6

docker run -d --name jemzabbix6 -h jemzabbix6 \
-p 225:22 -p 23306:3306 -p 280:80 -p 20051:10051 \
--net=mynet --ip 172.18.0.3 \
-v /sys/fs/cgroup:/sys/fs/cgroup \
--privileged=true \
techerwang/dbhub:jemzabbix62 /usr/sbin/init

--查看创建的容器
[root@jeames ~]# docker ps --format "table {{.ID}}\t{{.Names}}\t{{.Status}}" | grep -i jemzabbix6
9b658b6e1a38   jemzabbix6    Up About a minute

--设置容器开机自启动
[root@jeames ~]# docker update --restart=always jemzabbix6

--进入容器
[root@jeames ~]# docker exec -it jemzabbix6 bash[root@jemzabbix6 /]# cat /etc/redhat-release 
CentOS Linux release 8.2.2004 (Core)

⛳️ 2.Zabbix登陆使用

IP加端口号，端口号默认为80，可修改，后期下一步执行即可
默认用户名密码：Admin/zabbix

在这里插入图片描述

⛳️ 3.安装MySQL

本次采用yum在线rpm在线安装MySQL8.0

#repo下载[root@mysql8030 ~]# rpm -Uvh https://repo.mysql.com//mysql80-community-release-el8.rpm

⛳️ 4.安装Agent2

dnf install zabbix-agent2 zabbix-agent2-plugin-mongodb

[root@mysql8030 zabbix]# systemctl restart zabbix-agent2[root@mysql8030 zabbix]# systemctl enable zabbix-agent2[root@mysql8030 zabbix]# systemctl state zabbix-agent2       
Unknown operation state.

Sep 11 05:57:57 mysql8030 zabbix_agent2[1212]: Press Ctrl+C to exit.

⛳️ 5.配置agent参数文件

[root@mysql8030 ~]# vi /etc/zabbix/zabbix_agent2.confServer=172.18.0.3
ServerActive=172.18.0.4
Hostname=mysql8030
Timeout=10

参数说明：
server改成zabbix服务端的IP地址，Zabbix-server 地址，多个用","隔开
serveractive改成zabbix服务端的IP地址，主动检查本主机数据发送给 Zabbix-server
hostname改成本机的主机名，或本机的IP地址，被监控的主机名，需要和后续 server 端监控的主机名保持一致

sed -i "s/Server=127.0.0.1/Server=172.18.0.3/g" /etc/zabbix/zabbix_agent2.conf
sed -i "s/ServerActive=127.0.0.1/ServerActive=172.18.0.4/g" /etc/zabbix/zabbix_agent2.conf

##重启进程生效[root@mysql8030 ~]# systemctl restart zabbix-agent2

⛳️ 6.Zabbix Server添加主机

配置-->主机-->创建主机中操作
Zabbix6 自带MySQL模版，无须再使用第三方，也不用自己写监控脚本，
而且模板zabbix-agent2比zabbix-agent，功能更强大，应用也更简单

##主机server进程[root@jemzabbix6 ~]# netstat -anp | grep 10051##客户端服务器进程[root@mysql8030 ~]# netstat -anp | grep 10050
tcp        000.0.0.0:10050           0.0.0.0:*               LISTEN      301/zabbix_agentd   
tcp6       00 :::10050                :::*                    LISTEN      301/zabbix_agentd  

说明：
1.主机名称和zabbix-agent2.conf文件中Hostname匹配即可
2.agent配置要监控的MySQL服务器IP,端口默认为10050

##zabbix测试是否监控到数据，以下在Zabbix Server端操作
--是否连接mysql
[root@jemzabbix6 ~]# mysql -uroot -p -h172.18.0.4#查看Server日志LogFile=/var/log/zabbix/zabbix_server.log
[root@jemzabbix6 ~]# tail -n 50 /var/log/zabbix/zabbix_server.log#Web监控界面中文乱码处理1.在windows下面文件夹C:\Windows\Fonts找一个简体字文件例如simkai.ttf
2.复制到zabbix server的文件夹/usr/share/zabbix/fonts
3.注意：zabbix5的文件夹位置为/usr/share/zabbix/assets/fonts
4.覆盖原来的graphfont.ttf文件即可

[root@jeames ~]# docker cp simkai.ttf jemzabbix6:/[root@jemzabbix6 fonts]# pwd
/usr/share/zabbix/assets/fonts
[root@jemzabbix6 fonts]# cd /[root@jemzabbix6 /]# cp simkai.ttf /usr/share/zabbix/assets/fonts[root@jemzabbix6 fonts]# rm -rf graphfont.ttf5.找到zabbix 字符配置，切换即可,刷新页面，无需重启
find / -name defines.inc.php
/usr/share/zabbix/include/defines.inc.php

define('ZBX_GRAPH_FONT_NAME',           'graphfont'); // font file name
替换graphfont为simkai即可
