mysql中文乱码解决方法:将mysql数据库编码统一utf8

查看数据库编码:

show variables like ‘character%‘;

 

编辑/etc/my.cnf

[mysql]
default-character-set=utf8
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
default-character-set = utf8
character_set_server = utf8
#lower_case_table_names=1  忽略大小写
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
default-character-set = utf8
[mysql.server]
default-character-set = utf8
[client]
default-character-set = utf8

  

 

修改完成后,service mysql restart重启mysql服务就生效。注意:[mysqld]字段与[mysql]字段是有区别的。  

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):
SET NAMES ‘utf8‘;

它相当于下面的三句指令:

SET character_set_client = utf8;
SET character_set_results = utf8;
SET character_set_connection = utf8;

执行show variables like ‘character%‘ 跟下面一样说明修改成功

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)
