net_buffer_length = 2K
thread_stack = 64K?3、安装MySQL5的服务，服务名自己定义为MySQL5.1）、在DOS窗口下进入D:\mysql-5.0.67-win32\bin目录2）、执行安装MySQL服务名的命令：D:\mysql-5.0.67-win32\bin>mysqld --install MySQL5 --defaults-file=D:\mysql-5.0.67-win32\my-small.ini
Service successfully installed.?3）、启动MySQL5服务D:\mysql-5.0.67-win32\bin>net start mysql5
MySQL5 服务正在启动 .
MySQL5 服务无法启动。?4）、登陆MySQL5服务器D:\mysql-5.0.67-win32\bin>mysql -uroot -pEnter password:Welcome to the MySQL monitor.?

+------+------+
2 rows in set (0.00 sec)?13）、删除表mysql> drop table ttt;
Query OK, 0 rows affected (0.00 sec)?查看数据库中剩余的表：mysql> show tables;
Empty set (0.00 sec)??三、更改MySQL5数据库root用户的密码?1、使用mysql数据库mysql> use mysql
Database changed?2、查看mysql数据库中所有的表mysql> show tables;
