How to make sure that a certain Port is not occupied by any other process
提问by Aravind
I am working on a Java EE Application in a Windows environment. (I am using Windows 7)
我正在 Windows 环境中开发 Java EE 应用程序。（我使用的是 Windows 7）
I am using Tomcat Server, unfortunately port number 8080 is busy (used by Oracle). Now I want to assign a different port to Tomcat.
我正在使用 Tomcat 服务器，不幸的是端口号 8080 正忙（由 Oracle 使用）。现在我想为 Tomcat 分配一个不同的端口。
So before changing inside conf/server.xml file, I want to make sure that a certain port is not occupied by any other process and it's free.
所以在更改 conf/server.xml 文件之前，我想确保某个端口没有被任何其他进程占用并且它是免费的。

You can use "netstat" to check whether a port is available or not.
您可以使用“netstat”来检查端口是否可用。
Use the netstat -anp | find "port number"command to find whether a port is occupied by an another process or not. If it is occupied by an another process, it will show the process id of that process.
使用该netstat -anp | find "port number"命令查看端口是否被其他进程占用。如果它被另一个进程占用，它将显示该进程的进程ID。
You have to put : before port number to get the actual output
您必须在端口号之前放置：才能获得实际输出
Ex
netstat -anp | find ":8080"
前任
netstat -anp | find ":8080"

It's netstat -ano|findstr port no
它是 netstat -ano|findstr port no
Result would show process id in last column
结果将在最后一列中显示进程 ID

netstat -ano|find ":port_no"will give you the list.
a: Displays all connections and listening ports.
n: Displays addresses and port numbers in numerical form.
o: Displays the owning process ID associated with each connection .
netstat -ano|find ":port_no"会给你名单。
a：显示所有连接和监听端口。
n：以数字形式显示地址和端口号。
o：显示与每个连接关联的拥有进程 ID。
example : netstat -ano | find ":1900"This gives you the result like this.
示例：netstat -ano | find ":1900"这会给你这样的结果。
UDP 107.109.121.196:1900 *:* 1324
UDP 127.0.0.1:1900 *:* 1324
UDP [::1]:1900 *:* 1324
UDP [fe80::8db8:d9cc:12a8:2262%13]:1900 *:* 1324
