1，承接上一随笔，因为我用的是rmp的两种反式。
rpm -ivh MySQL-server-4.0.14-0.i386.rpm
rpm -ivh MySQL-client-4.0.14-0.i386.rpm
我发现在我的linux下/etc/目录下面没有我my.cnf文件。这听说是我用了这种方式安装mysql的问题
于是：
[root@iZ945sgm0ugZ etc]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
并在my.cnf的[client]下加了一行default-character-set=utf8
[client] #password = your_password default-character-set=utf8 port = 3306 socket = /var/lib/mysql/mysql.sock
且我还在［mysqld］下面加character-set-server=utf8
[mysqld] character-set-server=utf8
重新启动：
[root@iZ945sgm0ugZ etc]# /etc/init.d/mysql stop Shutting down MySQL... [ OK ] [root@iZ945sgm0ugZ etc]# /etc/init.d/mysql start Starting MySQL.. [ OK ]
乱码问题解决，ok
2，通过mysql的sql指令来设置
1，开启mysql服务，
2，输入指令，查看当前编码
mysql> show variables like 'collation_%'; +----------------------+-------------------+ | Variable_name | Value | +----------------------+-------------------+ | collation_connection | utf8_general_ci | | collation_database | latin1_swedish_ci | | collation_server | latin1_swedish_ci | +----------------------+-------------------+ 3 rows in set (0.00 sec) mysql> show variables like 'character_set_%'; +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | latin1 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 8 rows in set (0.00 sec)
mysql> set character_set_database=utf8; Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_server=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_client=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_connection=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_database=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_results=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_server=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_system=utf8;
Query OK, 0 rows affected (0.01 sec)
最终需要设置为：
mysql> show variables like 'collation_%'; +----------------------+-----------------+ | Variable_name | Value | +----------------------+-----------------+ | collation_connection | utf8_general_ci | | collation_database | utf8_general_ci | | collation_server | utf8_general_ci | +----------------------+-----------------+ 3 rows in set (0.00 sec) mysql> show variables like 'character_set_%'; +--------------------------+----------------------------+ | 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)
