docker+mysql基本搭建过程，及修改时间

[root@32c64-0425445 ~]# ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
或者
[root@32c64-0425445 ~]# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
或者
[root@32c64-0425445 ~]# systemctl enable ntpd
[root@32c64-0425445 ~]# systemctl start ntpd
或者
[root@32c64-0425445 ~]# timedatactl set-timezone Asia/Shanghai

若想改回UTC时间 删除/etc/localtime便可

[root@bms-e4e3 ~]# docker search mysql
