mac下修改mysql默认字符集为utf8

标签：mac mysql

1、首先检查默认安装的字符集

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-5.6.23-osx10.8-x86_64/share/charsets/ |
+--------------------------+--------------------------------------------------------+
8 rows in set (0.00 sec)

2、查看是否有my.cnf文件在/etc/目录下

ls -al /etc/

cp /usr/local/mysql/support-files/my-default.cnf /etc/

3、修改/etc/my-default.cnf文件名为my.cnf，并修改里面的配置

cat /etc/my.cnf

ls -l /etc/my.cnf

如果改为(666)(rw- rw- rw-)则修改以后配置文件不会生效。下面详细讲解为什么不会生效。

sudo chmod 664 /etc/my.cnf

4、修改配置文件内容

vi /etc/my.cnf

[client]
default-character-set=utf8

character-set-server=utf8

5、重新查看编码集

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-5.6.23-osx10.8-x86_64/share/charsets/ |
+--------------------------+--------------------------------------------------------+
8 rows in set (0.00 sec)

出现问题详解：

一开始我输入的命令为

<span style="color:#ff0000;">chmod a+w /etc/my.cnf</span>

直到我关闭了数据库服务，再进入数据库的时候，数据库出现一个错误

<span style="color:#ff0000;">World-writable config file '/etc/my.cnf' is ignored</span>

一下子我就懂了，打开数据库服务，修改成664后，再重启数据库，再查看编码已经成功修改。
