How to kill a process running on particular port in Linux?
提问by veer7
I tried to close the tomcat using ./shutdown.shfrom tomcat /bindirectory. But found that the server was not closed properly. And thus I was unable to restart
My tomcat is running on port 8080.
我尝试使用./shutdown.shfrom tomcat/bin目录关闭tomcat 。但是发现服务器没有正常关闭。因此我无法重新启动
我的 tomcat 正在端口上运行8080。
I want to kill the tomcat process running on 8080. I first want to have the list of processes running on a specific port (8080) in order to select which process to kill.
我想杀死正在运行的 tomcat 进程8080。我首先想要在特定端口 (8080) 上运行的进程列表，以便选择要杀死的进程。

Use the command
使用命令
sudo netstat -plten |grep java
used grep javaas tomcatuses javaas their processes.
使用grep java作为tomcat用途java作为他们的流程。
It will show the list of processes with port number and process id
它将显示带有端口号和进程 ID 的进程列表
tcp6 0 0 :::8080 :::* LISTEN
1000 30070621 16085/java
the number before /javais a process id. Now use killcommand to kill the process
前面的数字/java是进程 ID。现在使用kill命令杀死进程
kill -9 16085
-9implies the process will be killed forcefully.
-9意味着该进程将被强行杀死。

This fuser 8080/tcpwill print you PID of process bound on that port.
这fuser 8080/tcp将打印绑定在该端口上的进程的 PID。
And this fuser -k 8080/tcpwill kill that process.
这fuser -k 8080/tcp将终止该过程。
Works on Linux only. More universal is use of lsof -i4(or 6 for IPv6).
仅适用于 Linux。更普遍的是使用lsof -i4（或 6 用于 IPv6）。

This prints to stdout the process ids of everything running on <port_number>:
这将打印到 stdout 上运行的所有进程的进程 ID <port_number>：
fuser -n tcp <port_number>
It also prints some stuff to stderr, so:
它还会向 stderr 打印一些内容，因此：
fuser -n tcp <port_number> 2> /dev/null
We can then supply these process ids to the killcommand:
然后我们可以将这些进程 ID 提供给kill命令：
sudo kill $(fuser -n tcp <port_number> 2> /dev/null)
You could also put this in a function if you do it a lot:
如果你经常这样做，你也可以把它放在一个函数中：
function killport() {
sudo kill $(fuser -n tcp 2> /dev/null)
}

Linux: You can use this command if you know the port :
Linux：如果您知道端口，则可以使用此命令：
netstat -plten | grep LISTEN | grep 8080
AIX:
艾克斯：
netstat -Aan | grep LISTEN | grep 8080
You then take the first column (example: f100050000b05bb8) and run the following command:
然后获取第一列（例如：f100050000b05bb8）并运行以下命令：
rmsock f100050000b05bb8 tcpcb
kill process.
杀死进程。

To know the pid of service running on particular port :
要知道在特定端口上运行的服务的 pid：
netstat -tulnap | grep :*port_num*
you will get the description of that process. Now use kill or kill -9 pid. Easily killed.
您将获得该过程的描述。现在使用 kill 或 kill -9 pid。轻松杀死。
e.g
例如
netstat -ap | grep :8080
netstat -ap | grep :8080
tcp6 0 0 :::8080 :::* LISTEN 1880/java
Now:
现在：
kill -9 1880
Remember to run all commands as root
请记住将所有命令作为 root

You can use the lsof command. Let port number like here is 8090
您可以使用 lsof 命令。让这里的端口号是 8090
lsof -i:8090
This command returns a list of open processes on this port.
此命令返回此端口上打开的进程列表。
Something like…
就像是…
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
ssh 75782 eoin 5u IPv6 0x01c1c234 0t0 TCP localhost:8090 (LISTEN)
To free the port, kill the process using it(the process id is 75782)…
要释放端口，请使用它杀死进程（进程 ID 为 75782）...
kill -9 75782
This one worked for me. here is the link from the original post: link

try like this,
试试这样
sudo fuser -n tcp -k 8080

To list any process listening to the port 8080:
列出任何侦听端口 8080 的进程：
lsof -i:8080
To kill any process listening to the port 8080:
杀死任何监听端口 8080 的进程：
kill $(lsof -t -i:8080)
or more violently:
或更猛烈地：
kill -9 $(lsof -t -i:8080)
(-9corresponds to the SIGKILL - terminate immediately/hard killsignal: see List of Kill Signalsand What is the purpose of the -9 option in the kill command?. If no signal is specified to kill, the TERM signal a.k.a. -15or soft killis sent, which sometimes isn't enough to kill a process.).
（-9对应于SIGKILL - terminate immediately/hard kill信号：请参阅杀死信号列表和kill 命令中 -9 选项的用途是什么？。如果没有指定信号kill，则 TERM 信号又名-15或soft kill发送，有时不足以杀死一个过程。）。

lsof -i tcp:8000This command lists the information about process running in port 8000kill -9 [PID]This command kills the process
lsof -i tcp:8000该命令列出运行在 8000 端口的进程信息kill -9 [PID]此命令终止进程

In Windows, it will be netstat -ano | grep "8080"and we get the following message TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 10076
在 Windows 中，它将是netstat -ano | grep "8080"，我们收到以下消息TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 10076
WE can kill the PID using taskkill /F /PID 10076
我们可以使用杀死PID taskkill /F /PID 10076
