+--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | latin1 | | character_set_connection | latin1 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | latin1 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+
4. Modify the character encoding of mysql database
To modify the character encoding, you must modify the mysql configuration file my.cnf, and then restart to take effect
Usually you need to modify the following places of my.cnf:
Under [client], add default-character-set=utf8, or character_set_client= utf8
[mysqld] Below, add character_set_server = utf8;
Because of the above configuration, mysql defaults to latin1. If it is only through the command line client, mysql will not work after restarting .
The following is the client command line modification method. It is not recommended to use
mysql> set character_set_client=utf8 ; mysql> set character_set_connection=utf8 ; mysql> set character_set_database=utf8 ; mysql> set character_set_database=utf8 ; mysql> set character_set_results=utf8 ; mysql> set character_set_server=utf8 ; mysql> set character_set_system=utf8 ; mysql> show variables like 'character%'; +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 8 rows in set (0.00 sec)
