linux下查看端口占用情况:
1.
查看哪个进程占用了819端口:
case9-sghfofo:/usr/local/cnbj/tomcat-bj/bin # lsof -i:859
运行后的结果:
command pid user fd type device size node name
java 24907 root 31u ipv4 248905027 tcp *:859 (listen)
由以上我们知道了859端口被进程号为24907的进程占用了, 是个java进程。
2.
查看进程号为24907的进程在哪里:
case9-sghfofo:/usr/local/cnbj/tomcat-bj/bin # ps -ef|grep 24907
root 13421 29276 0 20:08 pts/2 00:00:00 grep 24907
root 24907 1 0 11:43 pts/4 00:03:53 /usr/java/jdk1.6.0_13/bin/java -server -xx:permsize=256m -xx:maxpermsize=512m -xbootclasspath/p:java-net-socket.jar -djava.util.logging.manager=org.apache.juli.classloaderlogmanager -djava.util.logging.config.file=/usr/local/cnsh/tomcat-sh/conf/logging.properties -djava.endorsed.dirs=/usr/local/cnsh/tomcat-sh/bin/endorsed -classpath :/usr/local/cnsh/tomcat-sh/bin/bootstrap.jar -dcatalina.base=/usr/local/cnsh/tomcat-sh/bin -dcatalina.home=/usr/local/cnsh/tomcat-sh/bin -djava.io.tmpdir=/usr/local/cnsh/tomcat-sh/bin/temp -xmx512m -xms256m org.apache.catalina.startup.bootstrap start
由以上我们知道是目录为/usr/local/cnsh/tomcat-sh/bin/的tomcat占用了。
