| 80端口被NT kernel & System 占用pid 4 | |||
前段时间停止了Apache，结果在打开的时候发现无法打开，80端口被占用，于是win+r 运行cmd 输入netstat -ano 加载中... 可以看到80端口被PID4占用，于是打开任务管理器-进程-查看，选择列，勾选PID 可以看到pid 4 的被NT kernel & System 占用 加载中... 在网上找了很久找到解决方案 http://www.cameroncooke.com/2009/01/25/windows-7-uses-port-80-and-makes-it-impossible-to-install-apache-solution/comment-page-1/#comments 原文： 翻译如下： 该进程是Http.sys。它是http API的驱动组件，Http栈服务器。如果该端口被Http.sys占用，说明一些正在使用http.sys的应用程序在运行。这就是阻止Apache运行的原因，因为Http.sys占用着80端口。我们提供了一种应用程序的机制来帮助控制端口共享，但是我需要调查导致你遇到这种困难的是什么特殊应用程序。如果你能提供给我们“netsh http show servicestate”这条命令的输出结果，我就能找出是哪个应用程序在使用Http.sys。在你禁用Http.sys之前，请按照下面的步骤来运行命令： 1. sc config http stat = demand 2. reboot 3. run the command(netsh http show servicestat)as administrator 在你使用这个命令之前，你可以按照下面步骤禁用http.sys： 1. net stop http 2. Sc config http start= disabled 于是运行net stop http 加载中... 按y 确定 加载中... 在运行 Sc config http start= disabled 加载中... 好了，现在启动Apache，可以启动了。 在查看一下netstat -ano 发现pid 4占用了445端口 |

| Mysql导出表结构及表数据 mysqldump用法 | |||
命令行下具体用法如下： mysqldump -u用戶名 -p密码 -d 数据库库名 表名 脚本名;
1、导出数据库为dbname的表结构（其中用戶名为root,密码为dbpasswd,生成的脚本名为db.sql）
mysqldump -uroot -pdbpasswd -d dbname >db.sql;
2、导出数据库库为dbname某张表为(test)结构
mysqldump -uroot -pdbpasswd -d dbname test>db.sql;
3、导出数据库库为dbname所有表结构及表数据库（不加-d）
mysqldump -uroot -pdbpasswd dbname >db.sql;
4、导出数据库库为dbname某张表为(test)结构及表数据库（不加-d）
mysqldump -uroot -pdbpasswd dbname test>db.sql;
5、导出数据库库为dbname某张表为(test)数据
mysqldump -uroot -pdbpasswd dbname test>db.sql;
6、指定条件导出数据库为dbname某张表为(test)数据（加-w）
mysqldump -uroot -pdbpasswd dbname test -w " 条件可带变量 ">db.sql;
