MySQL修改数据库时区

--查看数据库时区设置
mysql> show variables like "%time_zone%";
+------------------+--------+
| Variable_name    | Value  |
+------------------+--------+
| system_time_zone | UTC    |
| time_zone        | SYSTEM |
+------------------+--------+

--修改当前会话时区，退出msql后 time_zone 会恢复成修改前的值
mysql> set time_zone = '+8:00';
Query OK, 0 rows affected (0.00 sec)

mysql> show variables like "%time_zone%";
+------------------+--------+
| Variable_name    | Value  |
+------------------+--------+
| system_time_zone | UTC    |
| time_zone        | +08:00 |
+------------------+--------+

—-修改全局会话时区
mysql> set global time_zone = '+8:00';

mysql> set time_zone = '+8:00';

mysql> flush privileges;
