linux 释放9090端口

因部署web服务，发现9090端口被系统占用

执行 sudo lsof -i :9090

[root@localhost ~]# sudo lsof -i :9090
COMMAND PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
systemd   1 root  120u  IPv6  95684      0t0  TCP *:websm (LISTEN)

然后执行 systemctl list-sockets

发现是系统cockpit.service占用的该端口

执行  systemctl stop cockpit.socket 关闭该服务

[root@localhost ~]# systemctl stop cockpit.socket
[root@localhost ~]# sudo lsof -i :9090
[root@localhost ~]# 

端口释放成功
