Method 1: modify dynamically in mysql command line mode
1. View mysql's current time and current time zone
Select curtime (); # or select now ()
Show variables like 'time_zone%'; 2 rows in set (0.00 sec)
# time_zone indicates that mysql uses the time zone of system, while system_time_zone indicates that system uses CST time zone
2. Modify the time zone
Set global time_zone ='+ 8 set time_zone 00 hours; # # modify the global time zone of mysql to Beijing time, that is, our East 8 Zone flush privileges; ='+ 8 set time_zone 00 hours; # # modify the current session time zone effective immediately
Method 2: modify the time zone by modifying the my.cnf configuration file
Default-time_zone ='+ 8VR 00'
The modification is complete and restart the database server.
Method 3: with the help of PHP's mysql_connect () function (temporarily solve the time zone problem)
Mysql_query ("SET time_zone ='+ 8 00'")
This changes the time zone without rebooting. However, some system functions of mysql still cannot be used, such as: now (). This sentence is still incomprehensible.
