MYSQL创建utf-8格式的数据库
先mysql进入：

GBK: create database test2 DEFAULT CHARACTER SET gbk COLLATE gbk_chinese_ci;

UTF8: CREATE DATABASE `test2` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

eg：

[root@linuxtest test]# mysql -u root -p
Enter password:

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> CREATE DATABASE `test` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
Query OK, 1 row affected (0.06 sec)

mysql> show databases;
