mac下修改mysql的默认字符集为utf8

 

1,检查默认安装的mysql的字符集

 

mysql> show variables like '%char%';+--------------------------+--------------------------------------------------------+| 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/local/mysql-5.5.23-osx10.6-x86_64/share/charsets/ |+--------------------------+--------------------------------------------------------+8 rows in set (0.00 sec)

character_set_database和character_set_server依然是latin1的字符集，也就是说mysql后续创建的表都是latin1字符集的，不是utf8，会造成一些麻烦。所以有必要修改my.cnf，在修改my.cnf之前一定要关闭mysql进程，不然会遇到mysql的sock不能连接的问题。

2，关闭mysqld后台进程

系统偏好设置里面控制mysqld，避免了去找mysqld安装位置的麻烦。

点击 Stop MySQL Server

3，修改mysql配置文件/etc/my.cnf

sudo cp /usr/local/mysql/support-files/my-medium.cnf /etc/my.cnfsudo vi /etc/my.cnf[client]部分加入：default-character-set=utf8[mysqld]部分加入：character-set-server=utf8

退出并保存：

按住ctrl键再连按两次z键

修改完毕之后再启动mysql

4，检查结果：

mysql> show variables like '%char%';+--------------------------+--------------------------------------------------------+| 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/local/mysql-5.5.23-osx10.6-x86_64/share/charsets/ |+--------------------------+--------------------------------------------------------+8 rows in set (0.00 sec)修改完毕＃
