配置文件中zabbix-mysql挂载了当前路径下的mysql_data文件夹到容器中的/var/lib/mysql，这样容器中的mysql的数据文件可以在linux主机中查看，即使容器停止并删除，数据文件任然保存在linux主机上
注意：搭建前相应的容器停止并删除，否则可能不会在linux主机上显示容器内的mysql数据文件

挂载路径写相对路径，可以将整个文件夹整体拷贝到其他机器，方便迁移
当重新使用docker-compose加载镜像启动容器时，不会覆盖之前映射的linux主机文件夹，而是直接使用，如下进行测试
在mysql_data文件夹下新建一个test.txt文件，写入一些字符串
[root@centos71 mysql_data]# touch test.txt
[root@centos71 mysql_data]# vim test.txt
[root@centos71 mysql_data]# ls
auto.cnf client-cert.pem ibdata1 ibtmp1 private_key.pem server-key.pem zabbix
ca-key.pem client-key.pem ib_logfile0 mysql public_key.pem sys
ca.pem ib_buffer_pool ib_logfile1 performance_schema server-cert.pem test.txt
停止并删除容器，新建的test.txt文件仍然存在
[root@centos71 zabbix]# docker ps -a

重新使用docker-compose文件启动容器（因为之前的容器已经删除，所以从image启动新容器），test.txt文件仍然存在
