1. 安装Mysql
# sudo apt-get install mysql-server libmysql-ruby1.8
2. 在安装mysq的主机上用root用户创建一个链接，确保使用utf8字符集
# mysql -uroot -p"root的密码"
mysql> GRANT ALL PRIVILEGES ON *.* TO 'shenli'@'localhost'
IDENTIFIED BY 'shenli' WITH GRANT OPTION;
mysql> CREATE DATABASE shenli_db_name CHARACTER SET='utf8';
3. 设置所有的数据库变更
A) 继续运行上述2中得mysql 命令
mysql> set names utf8;
mysql> \q
B) 运行下面的命令来打开my.cnf (windows系统中是my.ini)
# sudo vi /etc/mysql/my.cnf
C) 添加下面的，并保存
[client]查找这个标记，添加下面的
default-character-set=utf8
[mysqld]
default-character-set=utf8
skip-character-set-client-handshake
E) 重新启动MySQL
# sudo /etc/init.d/mysql restart（windows中，如果开启了服务，可以使用net restart mysql命令来重启）
4. 查看更改结果
# mysql -uroot -p"root的密码”
mysql> status;
