I hope you can read it carefully and be able to achieve something!

I found that I could not start the jar package when I used the startup script of the written jar package on a machine in the production environment. Then I used the java command to start the jar package separately. The following error occurred

Root@aly-gz-web-1:/etc/init.d# java-Dfile.encoding=UTF-8-Xmx2048M\-Dcom.sun.management.jmxremote\-Dcom.sun.management.jmxremote.port=30113\-Dcom.sun.management.jmxremote.authenticate=false\-Dcom.sun.management.jmxremote.ssl=false\-jar / data/appdata/kjyl_1000020/kjly.jarError: Exception thrown by the agent: java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: aly-gz-web-1: aly-gz -web-1: Name or service not known this error is caused because the server cannot find the ip corresponding to the current hostname

Then I went to check the local / etc/hosts file and found that there was a problem with the mapping between the public network IP of the machine and the hostname of the machine in the hosts file, and then modified it to normal, as follows:

# Editing / etc/hosts file vim / etc/hosts# with problem 154.188.27.71 aly-gz-web-100# modified (correct hostname) 154.188.27.71 aly-gz-web-1

Finally, the jar package startup script is executed and started successfully.
