设置Mysql数据库的默认编码为utf8

1 次投票sunny 分享于 26 天 前, 2 条回复, 104 次浏览 Share | mysql的默认编码为latin1，存储中文时总会出现乱码，每次改过了，下次又忘了该怎么配，把它记录下来，也分享给各位。

进入mysql，查看默认编码：

$ mysql -uroot -proot

$ show variables like character%'

显示字符编码：

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

| 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/ |

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

现暂停mysql服务：

$sudo /etc/init.d/mysql stop

修改 /etc/mysql/my.cnf

$ sudo chmod 777 /etc/mysql/my.cnf

$ vim /etc/mysql/my.cnf

在client下面加上：

default-character-set=utf8

在mysqld下面加上：

default-character-set=utf8

init_connect='SET NAMES utf8'

保存，退出wq

重启mysql服务：

$sudo /etc/init.d/mysql start

发现出错：

Warning: World-writable config file '/etc/mysql/my.cnf' is ignored

/usr/bin/mysqladmin: connect to server at 'localhost' failed

error: 'Access denied for user 'luoping'@'localhost' (using password: NO)'

原因为：/etc/mysql/my.cnf 权限太高，搜索了一番，有人说许改为600，但是我发觉不行，查看了/etc/mysql/文件夹里的其他文件，权限是755，所以修改权限

$sudo chmod 755 /etc/mysql/my.cnf

重启mysql服务，OK

再次查看数据库编码

$ mysql -uroot -proot

$ show variables like character%'

显示字符编码：

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

| 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/ |

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

0 支持# 1 楼jerry 回复于 25 天 前貌似用windows的同学容易有这个数据库默认的编码问题。





0 支持# 2 楼aoner 回复于 20 天 前windows上更容易点吧，安装的时候有提示，可以自己选择编码，不用像linux安装完了在改配置文件
