Mysql 字符集问题2

修改mysql字符编码成为UTF8

关键字: mysql 编码

 

安装后

/etc/init.d/mysql start (stop) 为启动和停止服务器

/etc/mysql/ 主要配置文件所在位置 my.cnf

/var/lib/mysql/ 放置的是数据库表文件夹,这里的mysql相当于windows下mysql的date文件夹

 

启动mysql后,以root登录mysql

isher@isher-ubuntu:~$ mysql -u root

>show variables like 'character%'; #执行编码显示

+--------------------------+----------------------------+

| 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/ |

+--------------------------+----------------------------+

 

在某些时候,我们续要修改mysql默认数据库的编码,以保证某些迁移的程序可以正常显示,编辑my.cnf文件进行编码修改,windows可以直接用Mysql Server Instance Config Wizard 进行设置

 

在linux下修改3个my.cnf的1个/etc/mysql/my.cnf文件

 

找到客户端配置[client] 在下面添加

default-character-set=utf8 默认字符集为utf8

在找到[mysqld] 添加

default-character-set=utf8 默认字符集为utf8

init_connect='SET NAMES utf8' (设定连接mysql数据库时使用utf8编码,以让mysql数据库为utf8运行)

 

修改好后,重新启动mysql 即可,查询一下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/ |

+--------------------------+----------------------------+

 

 

 

此方法用于标准mysql版本同样有效,对于/etc/my.cnf文件,需要从mysql/support-files的文件夹cp my-large.cnf一份到/etc/my.cnf
