【Mysql】修改mysql时区

首先需要查看mysql的当前时区,用time_zone参数 mysql> show global variables like '%zone%'; +------------------+--------+ | Variable_name    | Value  | +------------------+--------+ | system_time_zone | CST    |      ---系统时间，北京时间 | time_zone        | SYSTEM |       ----mysql所用的时区，这里是调用系统时区，也就是北京时间 +------------------+--------+ 2 rows in set (0.17 sec) 验证下： mysql> select now(); +---------------------+ | now()               | +---------------------+ | 2018-11-30 17:11:55 | +---------------------+ 1 row in set (0.18 sec) 修改为utc时区 mysql> set time_zone='+0:00'; mysql> select now(); +---------------------+ | now()               | +---------------------+ | 2018-11-30 09:12:06 | +---------------------+ 1 row in set (0.18 sec) 修改为东八区 mysql> set time_zone='+8:00'; Query OK, 0 rows affected (0.24 sec)   mysql> select now(); +---------------------+ | now()               | +---------------------+ | 2018-11-30 17:21:40 | +---------------------+ 1 row in set (0.72 sec) 永久修改可以通过修改my.cnf 在 [mysqld] 之下加 default-time-zone=timezone 来修改时区。如： default-time-zone = '+8:00' 修改完了记得记得重启msyql 注意一定要在 [mysqld] 之下加 ，否则会出现 unknown variable 'default-time-zone=+8:00' 注意：时区这个对timestamp类型的才有影响，datetime 是没影响的，如： mysql> select * from uc_smallfeature_sharerecords(时间戳是timestamp类型); +------+---------------------+-------------+----------+--------+----------+ | id   | create_time         | destination | platform | userid | username | +------+---------------------+-------------+----------+--------+----------+ | 3425 | 2018-12-25 19:42:51 | 123213      | 123      | 123    | 123      | +------+---------------------+-------------+----------+--------+----------+ mysql> select * from uc_push_token（时间戳是datetime类型）; +---------+-----------+-------+---------------------+---------------------+ | user_id | push_type | token | create_time         | update_time         | +---------+-----------+-------+---------------------+---------------------+ |       1 |         0 |       | 2018-12-25 19:40:49 | 2018-12-25 19:40:49 | +---------+-----------+-------+---------------------+---------------------+ mysql> show global variables like '%zone%'; +------------------+--------+ | Variable_name    | Value  | +------------------+--------+ | system_time_zone | UTC    | | time_zone        | +08:00 | +------------------+--------+ 2 rows in set (0.00 sec) mysql> set global time_zone='+0:00'; Query OK, 0 rows affected (0.00 sec) 重连查询： mysql> select * from uc_smallfeature_sharerecords;（timestamp类型的变了） +------+---------------------+-------------+----------+--------+----------+ | id   | create_time         | destination | platform | userid | username | +------+---------------------+-------------+----------+--------+----------+ | 3425 | 2018-12-25 11:42:51 | 123213      | 123      | 123    | 123      | +------+---------------------+-------------+----------+--------+----------+ 1 row in set (0.00 sec) mysql> select * from uc_push_token;（datetime类型的不会变） +---------+-----------+-------+---------------------+---------------------+ | user_id | push_type | token | create_time         | update_time         | +---------+-----------+-------+---------------------+---------------------+ |       1 |         0 |       | 2018-12-25 19:40:49 | 2018-12-25 19:40:49 | +---------+-----------+-------+---------------------+---------------------+
