Docker 官方镜像构建你的zabbix 5.x
环境准备
Docker CE版本，以及mysql zabbix nginx镜像准备好，这些镜像都可以去使用docker pull去官方仓库拉取下来

#注：不要下载最新版本的mysql，不然后面server 无法在mysql上进行注册，会报 “MySQL server is not available. ” 错误

先启动一个单独的数据库mysql用于保存zabbix数据
#注： 启动命令中不要添加 MYSQL_DATABASE="zabbix" 参数，不然后期同样在server上注册不上，会报user表为空的错误。同时--restart=always写在-d mysql:5.7的前面，要不然容器启动失败

5 rows in set (0.01 sec)定义了数据库名zabbix，数据库用户zabbix，密码zabbix，在本地目录/home/zabbix/data中持久化保存mysql容器运行中的数据，确保容器退出运行后，数据不会丢失，最后两条是定义了数据库的字符集为utf8，解决了mysql数据库保存中文的问题
然后启动Zabbix Server实例，并关联这个实例到已创建的MySQL实例

#zabbix server数据库配置信息如下：
#指定数据库主机
bash-5.0$ cd /etc/zabbix/
bash-5.0$ grep DBHost zabbix_server.conf
DBHost=mysql-server
#指定密码
bash-5.0$ grep DBPassword zabbix_server.conf
DBPassword=zabbix启动zabbix server服务，并关联这个服务到上面已经启动的mysql数据库实例上，确保zabbix的数据可以保存到mysql数据库，如果想要数据持久化根据生产环境实际情况灵活决定是否挂载，上面我没有挂载，即没有使用卷持久化。
最后启动Zabbix web 接口，并将它与MySQL服务器实例和Zabbix Server实例关联
[root@www ~]# docker run --name zabbix-web-nginx-mysql -t \
> -e DB_SERVER_HOST="mysql-server" \
> -e MYSQL_DATABASE="zabbix" \
> -e MYSQL_USER="zabbix" \

> -e PHP_TZ="Asia/Shanghai" \
> --link mysql-server:mysql \
> --link zabbix-server-mysql:zabbix-server\
> -p 8080:8080 \

#web端数据库信息配置如下：
bash-5.0$ cat /etc/zabbix/web/zabbix.conf.php
link mysql-server:mysql 连接数据库实例，mysql-server必须要与第一步的--name mysql-server完全一致
--link zabbix-server-mysql:zabbix-server 连接zabbix服务器实例，zabbix-server-mysql必须要与第二步的--name zabbix-server-mysql完全一致
打开zabbix web界面
可以看到大功告成！
最后将这三个容器的启动命令记录一下：
docker run --name mysql-server -t \
-p 3306:3306 \
-e MYSQL_USER="zabbix" \
-e MYSQL_PASSWORD="zabbix" \
-e MYSQL_ROOT_PASSWORD="zabbix" \

-e MYSQL_USER="zabbix" \
-e MYSQL_PASSWORD="zabbix" \
-e MYSQL_ROOT_PASSWORD="zabbix" \

--link mysql-server:mysql \
