There are many reasons for the problem, and the title does not explain the specific problem.

Here I only talk about my operation, the problems encountered and their solutions, hoping to play a role in attracting jade.

Start tomcat with the following error:

Error: exception thrown by the agent: java.rmi.server.exportexception: port already in use: 7800; nested exception is:

Java.net.bindexception: address already in use

The configuration files such as ${tomcat_home} / conf/server.xml,context.xml,web.xml were checked and no configuration of port 7800 was found.

So google search, an article gave me a hint:

So the answer is found in the ${tomcat_home} / bin/catalina.sh startup file.

Java_opts= "- server-xms2048m-xmx2048m-xx:permsize=512m-xx:maxpermsize=512m-dcom.sun.management.jmxremote-dcom.sun.management.jmxremote.pwd.file=/opt/app/appcode/jmxremote.password-dcom.sun.management.jmxremote.ssl=false-dcom.sun.management.jmxremote.authenticate=false-dcom.sun.management.jmxremote.port=7803"
