在启动Apache的时候遇到占用80端口,导致服务不能启动,于是CMD查占用80端口的进程..
直接命令杀死进程:
1.查进程:
netstat -b -n –a
-b 为列出进程,必须-b在前,不能是-a在前不然报错.
-n为端口号
查到是peer.exe 进程PID 632
2.杀占用80的进程
CMD下杀进程的命令ntsd.
ntsd –c q –p 632
632为我查到的进程 peer.exe(fs2you网络硬盘的程序)的id
截图:
CMD输出:
C:/Documents and Settings/Administrator>netstat -n -b -a
Active Connections
Proto Local Address Foreign Address State PID TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 632 [peer.exe]
TCP 0.0.0.0:135 0.0.0.0:0 LISTENING 1236 ^C C:/Documents and Settings/Administrator>ntsd -c q -p 632
C:/Documents and Settings/Administrator>
杀完之后apache启动正常...

xp下还有两个好东东tasklist和tskill。tasklist能列出所有的进程，和相应的信息。tskill能查杀进程，语法很简单：tskill 程序名！！
NETSTAT [-a] [-b] [-e] [-n] [-o] [-p proto] [-r] [-s] [-v] [interval]
-a 显示所有连接和监听端口。 -b 显示包含于创建每个连接或监听端口的 可执行组件。在某些情况下已知可执行组件 拥有多个独立组件，并且在这些情况下 包含于创建连接或监听端口的组件序列 被显示。这种情况下，可执行组件名 在底部的 [] 中，顶部是其调用的组件， 等等，直到 TCP/IP 部分。注意此选项 可能需要很长时间，如果没有足够权限 可能失败。 -e 显示以太网统计信息。此选项可以与 -s 选项组合使用。 -n 以数字形式显示地址和端口号。 -o 显示与每个连接相关的所属进程 ID。 -p proto 显示 proto 指定的协议的连接；proto 可以是 下列协议之一: TCP、UDP、TCPv6 或 UDPv6。 如果与 -s 选项一起使用以显示按协议统计信息，proto 可以是下列协议之一: IP、IPv6、ICMP、ICMPv6、TCP、TCPv6、UDP 或 UDPv6。 -r 显示路由表。 -s 显示按协议统计信息。默认地，显示 IP、 IPv6、ICMP、ICMPv6、TCP、TCPv6、UDP 和 UDPv6 的统计信息； -p 选项用于指定默认情况的子集。 -v 与 -b 选项一起使用时将显示包含于 为所有可执行组件创建连接或监听端口的 组件。 interval 重新显示选定统计信息，每次显示之间 暂停时间间隔(以秒计)。按 CTRL+C 停止重新 显示统计信息。如果省略，netstat 显示当前 配置信息(只显示一次)
