Does Linux check whether tomcat port is occupied?
Mine: linux needs to use the command of netstat-ano|grep port number to check whether the tomcat port is occupied.
Generally, the port used by tomcat is in the configuration file under the installation directory, which is located in Tomcat's installation directory /conf/server.xml file. The general code is as follows:
connector port = 8080 protocol = HTTP/ 1. 1 connection time out = 20000 redirect port = 8443/>
TCP8080 port is tomcat's stat-plantup|grep8080, so you can see whether Tomcat's port is open or occupied.
Then use fuser-v8080/tcp to find out which program or process is occupied by tomcat's port.
