解决docker中mysql时区问题_杨园亮的博客-CSDN博客

问题
数据库插入的时间统统相差8个小时。

//初步怀疑服务器时间不对。date看下时间是对的
//然后怀疑代码问题，检查代码后没有问题
//最后怀疑mysql的问题。
--docker exec -it mysql /bin/bash
--mysql -uroot -p 
--show variables like '%time_zone%'
    +------------------+--------+
    | Variable_name    | Value  |
    +------------------+--------+
    | system_time_zone | UTC    |
    | time_zone        | SYSTEM |
    +------------------+--------+
//可见使用的是系统时区

//改文件
-- docker cp mysql:/etc/mysql/my.cnf ./my.cnf
-- vim my.cnf 最后一行加上
default-time-zone = '+8:00'
-- docker cp ./my.cnf mysql:/etc/mysql/my.cnf
-- docker container mysql restart

vi 命令不可用
