Switch to UTF-8 charset in Mysql on Ubuntu 对于Ubuntu的Mysql中, 选择UTF-8编码

对于Ubuntu的Mysql中, 选择UTF-8编码

 

当在Ubuntu中安装Mysql时, 默认的编码集可能是latin-1. 既然Ubuntu使用UTF-8作为大多数东西的编码集, 这样(latin-1)做就有点奇怪了. 但实际上很容易设置.

 

Mysql的配置文件 /etc/mysql/my.cnf 有神奇的一行:

 

!includedir /etc/mysql/conf.d/

这就使得它包含的设置都位于 conf.d 的子目录下. 不推荐去直接改变 my.cnf文件, 因为它会导致一些问题, 当在升级 Ubuntu/Mysql 到一个新的版本时.

 

创建一个新文件: /etc/mysql/conf.d/utf8_charset.cnf 有下面这些内容

Mysql 5.1

[mysqld]
default-character-set=utf8

[client]
default-character-set=utf8

Mysql 5.5

[mysqld]
character-set-server=utf8
collation-server=utf8_general_ci

[client]
default-character-set=utf8

重启mysql, 然后你将会拥有UTF-8的编码集:

$ mysql -u root -p -e "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/ |
+--------------------------+----------------------------+
