mysql> show variables like 'character_set_%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |

8 rows in set (0.00 sec)

ctrl+c 退出到终端

#whereis mysql

#find / -name 'my.cnf'

找到哦啊my.cnf在/etc/mysql/my.cnf

#vim /etc/mysql/my.cnf

在【client】下面加入

default-character-set=utf8

在【mysqld】下面加入

default-character-set=utf8

：wq

退出后

#/etc/init.d/mysql restart

提示

root@debian:/# /etc/init.d/mysql restart
Stopping MySQL database server: mysqld
.
Starting MySQL database server: mysqld.
Checking for corrupt, not cleanly closed and upgrade needing tables..

这个只是个提示，告诉你在做什么。不管它

再次进去mysql

#mysql -u root -p

#

输入

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/ |
+--------------------------+----------------------------+

修改成功。再次查询数据。就好了

注意 如果修改后不能启动报错

试试把default-character-set=utf8改为character_set_server=utf8 改成后面这个,只需要mysqld下面的.client就不需要加了

5.5后的需要用改成这几个参数

[client] 下面加

default-character-set=utf8

[mysqld]
default-storage-engine=INNODB
character-set-server=utf8
collation-server=utf8_general_ci
