- 通过应用找占用的端口
1. 查找进程的pid
[root@F6-test-web1 ~]# ps -aux | grep passport
root 17408 0.5 2.5 4770388 828124 ? Sl 10:02 4:13 java -Xms1g -Xmx1g -Xmn512m -server -jar -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005 -Dspring.profiles.active=local-test /home/opt/f6-passport-8076/passport.jar
root 26856 0.0 0.0 112708 972 pts/2 S+ 22:00 0:00 grep --color=auto passport
2. 通过pid查找占用的端口
[root@F6-test-web1 ~]# netstat -anop | grep 17408
