Troubleshooting of MySQL Chinese garbled characters in Ubuntu 9.04

Source: Internet

MySQL is installed with the source in Ubuntu 9.04. By default, mysql shell is used to log on to create a database, create a table, and insert Chinese data. The select statement is used to identify Chinese, but garbled characters are displayed when JDBC is used. The solution is as follows (back up data first ):

Modify/etc/mysql/my. cnf
Sudo gedit/etc/mysql/my. cnf

Add the following two lines to the [client] and [mysqld] segments in the my. cnf file:
[Client]
Default-character-set = utf8
[Mysqld]
Default-character-set = utf8

Mysql service needs to be restarted
Disable:
Sudo mysqladmin shutdown-u root-p
Enter the mysql root User Password.
Enable:
Sudo mysqld_safe-user = mysql &

Check the current mysql encoding.
Sudo mysql-u root-p

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/|
+ -------------------------- + ---------------------------- +

Now, both mysql shell and JDBC can display Chinese characters normally. But the previous data is still not good, http://ubuntuone.cn so before this back up data, modify the encoding and then import.
