mysql修改编码utf8

 

摘要:使用apt-get 命令安装的mysql默认不是utf8、在这里记录一下如何将编码修改成utf8。

Linux学习笔记之——ubuntu中mysql修改编码utf8

一:查看mysql版本

1.1 mysql –V

在终端界面输入上面命令、显示如下:

mysql  Ver  14.14 Distrib  5.5 . 35 , fordebian-linux-gnu (x86_64) using readline  6.2

1.2 status

a) 登录mysql

mysql –uroot –ppassword

b) 输入如下命令:

status
#会有如下显示:
--------------

--------------

1.3 selectversion();

a) 登录mysql

mysql –uroot –ppassword

b) 输入如下命令:

select version();
#会有如下显示:

+-------------------------+
| version()               |
+-------------------------+
|  5.5 . 35 -0ubuntu0. 12.04 . 2 |
+-------------------------+
1 row in set ( 0.00 sec)

二:查看mysql编码

2.1 登录mysql

a) 输入命令:

mysql  –uroot  –p

b) 输入密码:

password

2.2 查看mysql编码

show variables like  '%character%' ;
#会有如下显示:
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | utf8                       |
| character_set_connection | utf8                       |
|character_set_database   | latin1                     |
| character_set_filesystem | binary                     |
| character_set_results    | utf8                       |
|character_set_server     | latin1                     |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set ( 0.00 sec)

三:修改mysql编码

上面步骤中可以看出红色的部分的编码——latin1

3.1 修改mysql的配置文件——/etc/mysql/my.cnf:

a) 打开mysql配置文件:

vim/etc/mysql/my.cnf

b) 在[client]下追加:

default -character-set=utf8

c) 在[mysqld]下追加:

character-set-server=utf8

d) 在[mysql]下追加:

default -character-set=utf8

e) 保存并退出

3.2 重启mysql服务

下面两个任何一个都可以:

servicemysql restart
/etc/init.d/mysqlrestart

3.3 查看mysql编码是否修改成功

a) 登录mysql

b) 输入:

show variables like  '%character%' ;
#会有如下显示:
+--------------------------+----------------------------+
| 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/ |
+--------------------------+----------------------------+

则修改成功!
