Linux查看程序端口占用情况

Linux查看程序端口占用情况


首先使用netstat命令查看其占用的端口：

netstat -anp | grep 9082

tcp6       0      0 :::9082                 :::*                    LISTEN      14155/java

查到进程id之后，用ps命令查看进程的详情：

ps -ef | grep  14155

root     14155     1  0 10月30 ?      00:59:48 /usr/java/bin/java -Djava.util.logging.config.file=/usr/local/demo/apache-tomcat-7.0.77/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Xms128m -Xmx1024m -XX:PermSize=64M -XX:MaxPermSize=512M -Djava.endorsed.dirs=/usr/local/demo/apache-tomcat-7.0.77/endorsed -classpath /usr/local/demo/apache-tomcat-7.0.77/bin/bootstrap.jar:/usr/local/demo/apache-tomcat-7.0.77/bin/tomcat-juli.jar -Dcatalina.base=/usr/local/demo/apache-tomcat-7.0.77 -Dcatalina.home=/usr/local/demo/apache-tomcat-7.0.77 -Djava.io.tmpdir=/usr/local/demo/apache-tomcat-7.0.77/temp org.apache.catalina.startup.Bootstrap start
root     19552  9347  0 11:13 pts/0    00:00:00 grep 14155

或者 ps -aux | grep  14155

root     14155  0.1  2.1 4758652 341376 ?      Sl   10月30  59:48 /usr/java/bin/java -Djava.util.logging.config.file=/usr/local/demo/apache-tomcat-7.0.77/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Xms128m -Xmx1024m -XX:PermSize=64M -XX:MaxPermSize=512M -Djava.endorsed.dirs=/usr/local/demo/apache-tomcat-7.0.77/endorsed -classpath /usr/local/demo/apache-tomcat-7.0.77/bin/bootstrap.jar:/usr/local/demo/apache-tomcat-7.0.77/bin/tomcat-juli.jar -Dcatalina.base=/usr/local/demo/apache-tomcat-7.0.77 -Dcatalina.home=/usr/local/demo/apache-tomcat-7.0.77 -Djava.io.tmpdir=/usr/local/demo/apache-tomcat-7.0.77/temp org.apache.catalina.startup.Bootstrap start
root     19585  0.0  0.0 112720   952 pts/0    R+   11:13   0:00 grep 14155

可以看到，9092端口是被14155（进程编号）的进程所占用了，下面我们来关闭这个进程。

kill -9 14155
