Preface

The server is the Linux-Centos7 system, yesterday there was a very strange situation, tomcat has been closed, still shows that its port 8080 is occupied, and finally located to occupy the port of the process, to solve the problem, the following words do not say much, let's take a look at the detailed introduction.

1. View the processes occupying the port netstat-lnp | grep 8080

[root@izbp109iqt20o2h73tpcuvz java] # netstat-lnp | grep 8080tcp6 0 0: 8080: * LISTEN 4486/java

As you can see, it is 4486 of a java process that occupies port 8080.

two。 View process information ps 4486

[root@izbp109iqt20o2h73tpcuvz java] # ps 4486 PID TTY STAT TIME COMMAND 4486? Sl 1:16 / usr/local/java/jdk1.8.0_152/jre/bin/java-Djava.util.logging.config.file=/usr/local/j

3. Forced killing process kill-9 4486

[root@izbp109iqt20o2h73tpcuvz java] # kill-9 4486 [root@izbp109iqt20o2h73tpcuvz java] # netstat-lnp | grep 8080 [root@izbp109iqt20o2h73tpcuvz java] #

After killing the process, check the port occupancy again and find that there is no port occupancy. The problem is solved.

The complete operation record is as follows:

[root@izbp109iqt20o2h73tpcuvz java] # netstat-lnp | grep 8080tcp6 0 0:: 8080: * LISTEN 4486/java [root@izbp109iqt20o2h73tpcuvz java] # ps 4486 PID TTY STAT TIME COMMAND 4486? Sl 1:16 / usr/local/java/jdk1.8.0_152/jre/bin/java-Djava.util.logging.config.file=/usr/local/j [root@izbp109iqt20o2h73tpcuvz java] # kill-9 4486 [root@izbp109iqt20o2h73tpcuvz java] # netstat-lnp | grep 8080 [root@izbp109iqt20o2h73tpcuvz java] #
