mysql修改字符集


mysql 默认client server 字符集是 latinl，为防止有乱码，全部都改为utf-8

1.查看mysql的字符集

mysql> show variables like '%char%';

+--------------------------+----------------------------------+

| Variable_name | Value |

+--------------------------+----------------------------------+

| character_set_client | latinl |

| character_set_connection | latinl |

| character_set_database | utf8 |

| character_set_filesystem | binary |

| character_set_results | utf8 |

| character_set_server | latinl |

| character_set_system | utf8 |

| character_sets_dir | /usr/local/mysql/share/charsets/ |

+--------------------------+----------------------------------+

8 rows in set (0.02 sec)

2.编辑参数文件 my.cnf,里面加入以下参数,修改后重启服务

[root@zw oradata]# vi /etc/my.cnf

[client]

default-character-set=utf8

[mysqld]

character-set-server=utf8

3.再次查看mysql的字符集

mysql> show variables like '%char%';

+--------------------------+----------------------------------+

| 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/local/mysql/share/charsets/ |

+--------------------------+----------------------------------+

可以看到现在都是utf-8了
