mysql编码修改

查看mysql指定数据库编码

mysql> show create database php;
+----------+-------------------------------------------------------------+
| Database | Create Database                                             |
+----------+-------------------------------------------------------------+
| php      | CREATE DATABASE `php` /*!40100 DEFAULT CHARACTER SET gbk */ |
+----------+-------------------------------------------------------------+
1 row in set (0.00 sec)
mysql> show create database mysql;
+----------+----------------------------------------------------------------+
| Database | Create Database                                                |
+----------+----------------------------------------------------------------+
| mysql    | CREATE DATABASE `mysql` /*!40100 DEFAULT CHARACTER SET utf8 */ |
+----------+----------------------------------------------------------------+
1 row in set (0.00 sec)

查看数据库服务和客户端字符集，mysql默认编码是gbk的：

永久生效，修改my.ini文件

[client]

#password = your_password

port = 3306

socket = /tmp/mysql.sock

default-character-set=utf8 //加上这一行，重启mysql服务

mysql> status
Server characterset:    latin1
Db     characterset:    latin1
Client characterset:    utf8
Conn.  characterset:    utf8

修改某个数据库编码

mysql> alter database res_gul character set utf8;

mysql> use res_gul
mysql> status
Server characterset:    latin1
Db     characterset:    utf8
Client characterset:    utf8
Conn.  characterset:    utf8

设置数据库编码 /etc/my.cnf

[mysqld]

default-character-set=utf8

...

[client]

default-character-set=utf8

重启数据库后生效

mysql> status
Server characterset:    utf8
Db     characterset:    utf8
Client characterset:    utf8
Conn.  characterset:    utf8
