mysql乱码问题解决方法

修改数据库mysql字符编码为UTF8

 

Mysql数据库是一个开源的数据库，应用非常广泛。以下是修改mysql数据库的字符编码的操作过程。

步骤1：查看当前的字符编码方法

mysql> show variables like'character%';

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

|Variable_name           |Value                     |

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

|character_set_client    |latin1                    |

| character_set_connection |latin1                    |

| character_set_database   |latin1                    |

| character_set_filesystem |binary                    |

|character_set_results   |latin1                    |

|character_set_server    |latin1                    |

|character_set_system    |utf8                      |

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

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

8 rows in set (0.00 sec)

 字符编码为latin1时，用户在给数据表插入一条字符类型（char）的记录，在显示此记录时可能会无法正常显示字符类型的数据，故此处我们将mysql字符编码修改为UTF8。操作如下：

步骤2：修改my.cnf配置文件，修改后如下：

[client]

#password      = your_password

port           = 3306

socket         = /var/lib/mysql/mysql.sock

default-character-set=utf8     #设置默认编码为UTF8

 

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

user=mysql

default-character-set=utf8

init_connect='SET NAMES utf8'

 

# Default to using old password format for compatibility withmysql 3.x

# clients (those using the mysqlclient10 compatibilitypackage).

old_passwords=1

 

[mysqld_safe]

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

步骤3，重启mysql数据库。

步骤4，重新连接mysql数据库，并查看mysql的字符编码。

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)
