mysql免安装使用说明 1>把压缩文件mysql-noinstall-5.1.6-alpha-win32.zip解压到一个目录下,在环境变量中设置MYSQL_HOME,把%MYSQL_HOME%/bin 加入到 path。 2>创建my.ini配置文件,内容如下:[mysqld]#设置basedir指向mysql的安装路径basedir=.../mysqldatadir=.../mysql/data my.ini文件放在系统文件下面。 3>启动与停止mysqlmysqld.exe --install(安装windows服务,卸载使用mysqld.exe --remove )启动:net start mysql停止:net stop mysql 4>连接mysql格式: mysql -h主机地址 -u用户名 -p用户密码例1:连接到本机上的mysqlmysql -uroot -p例2:连接到远程主机上的mysqlmysql -h110.110.110.110 -uroot -pabcd123 5>退出mysql命令exit(回车)或者quit(回车) 6>修改密码格式:mysqladmin -u用户名 -p旧密码 password 新密码例:给root加个密码ab12。首先在DOS下进入目录mysqlbin,然后键入以下命令mysqladmin -uroot password ab12注:因为开始时root没有密码,所以-p旧密码一项就可以省略了。2、 例2:再将root的密码改为djg345。mysqladmin -uroot -pab12 password djg345下面的是mysql环境中的命令, 以分号作为命令结束 7>增加新用户格式:grant select on 数据库.* to 用户名@登录主机 identified by "密码";例1、增加一个用户test1密码为abc,让他可以在任何主机上登录, 并对所有数据库有查询、插入、修改、删除的权限。首先用以root用户连入mysql,然后键入以下命令:grant select,insert,update,delete on *.* to test1@"%"
Identified by "abc";例2、增加一个用户test2密码为abc,让其只可以在localhost上登录, 并可以对数据库mydb进行查询、插入、修改、删除的操作(localhost指本地主机, 即mysql数据库所在的那台主机),这样用户即使用知道test2的密码,也无法从internet上直接访问数据库,只能通过mysql主机上的web页来访问了。grant select,insert,update,delete on mydb.* to test2@localhost identified by "abc"; 8>显示数据库列表show databases;9>显示库中的数据表use mysql;//数据库名称show tables;10>显示数据表的结构describe 表名;11>建库create database 库名;12>建表use 库名;create table 表名( ...... 参考相关文章: http://www.ej38.com/showinfo/mysql-107727.html 安装配置 http://dev.mysql.com/doc/refman/5.1/zh/sql-syntax.html MySQL语法
