linux下mysql中文乱码(中文问号)解决办法
http://www.111cn.net/sys/linux/53209.htm今天发现我mysql插入中文时老出现????号了,但保存英文是没有问题的,下面我来给各位同学介绍一下linux下mysql中文乱码解决方法。linux下则需要修改/etc/my.cnf,在[mysqld]下加入default-character-set = utf8,[client]下加入d
实现:
1.查看原编码
代码如下 | 复制代码 |
mysql> show variables like 'character%'; //执行编码显示,可以看到默认是latin1 +--------------------------+----------------------------+ | 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/ | +--------------------------+----------------------------+ |
2.修改/etc/my.cnf,分别在[client],[mysqld],[mysql]字段里添加default-character-set=utf8。注意[mysqld]字段与[mysql]字段是有区别的。这点在网上没人反馈过。
# vim /etc/my.cnf //添加default-character-set=utf8
代码如下 | 复制代码 |
[client] [mysqld] [mysql] |
default-character-set=utf8修改完成后,service mysql restart重启mysql服务器,使用SHOW VARIABLES LIKE ‘character%’;查看,发现数据库编码全已改成utf8
代码如下 | 复制代码 |
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/local/mysql/share/mysql/charsets/ | +--------------------------+----------------------------------------+ |
3.如果上面的都修改了还乱码,那剩下问题就一定在connection连接层上。解决方法是在发送查询前执行一下下面这句(直接写在SQL文件的最前面):
代码如下 | 复制代码 |
SET NAMES ‘utf8′; |
它相当于以下三指令:
代码如下 | 复制代码 |
SET character_set_client = utf8; SET character_set_results = utf8; SET character_set_connection = utf8; |

朋友的一个站点转到我这边。导入mysql时,mysql还是latin的编码,因此,虽然按上面的步骤,在/etc/my.cnf文件中[client],[mysqld],[mysql]字段里添加default-character-set=utf8,但站点部分中文是乱码。在将mysql编辑改为utf8再重新导入数据库后,就正常了。
估计是mysql是latin编码是,导入数据时,因为mysql无法识别,直接将数据保存成了???这种乱码的形式了
