Linux下經過進程名查詢佔用的端口

一、首先根據名稱用ps命令查看進程ID：

ps -ef | grep zookeeper 

jim      10997  1959  0 12月14 pts/2  00:00:01 /usr/lib/jvm/java-8-oracle/bin/java -Dzookeeper.log.dir=. -Dzookeeper.root.logger=INFO,CONSOLE -cp /home/jim/opt/zookeeper-3.4.9/bin/../build/classes:/home/jim/opt/zookeeper-3.4.9/bin/../build/lib/*.jar:/home/jim/opt/zookeeper-3.4.9/bin/../lib/slf4j-log4j12-1.6.1.jar:/home/jim/opt/zookeeper-3.4.9/bin/../lib/slf4j-api-1.6.1.jar:/home/jim/opt/zookeeper-3.4.9/bin/../lib/netty-3.10.5.Final.jar:/home/jim/opt/zookeeper-3.4.9/bin/../lib/log4j-1.2.16.jar:/home/jim/opt/zookeeper-3.4.9/bin/../lib/jline-0.9.94.jar:/home/jim/opt/zookeeper-3.4.9/bin/../zookeeper-3.4.9.jar:/home/jim/opt/zookeeper-3.4.9/bin/../src/java/lib/*.jar:/home/jim/opt/zookeeper-3.4.9/bin/../conf: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /home/jim/opt/zookeeper-3.4.9/bin/../conf/zoo.cfg

10997爲進程ID

後面是啓動路徑和對應的進程名

1.一、對於在Java虛擬機中運行的進程，好比tomcat的守護進程，能夠直接用jsp命令查看：

jps -l | grep zookeeper

10997 org.apache.zookeeper.server.quorum.QuorumPeerMain

已經知道進程的確切名稱，能夠用pidof查看： 

pidof Name    

不過這個通常少用，由於真的很難查 

二、查到進程ID以後，使用netstat命令查看其佔用的端口：

netstat -anp | grep 10997 

tcp6       0      0 :::43125                :::*                    LISTEN      10997/java      
tcp6       0      0 :::2181                 :::*                    LISTEN      10997/java

紅色的爲佔用的端口，LISTEN爲佔用的類型，綠色粗體爲進程ID
