I am trying to configure a CentOs server in DigitalOcean. I have followed all those steps mentioned in their website.This is the link of various steps to configure server. DigitalOcean. I followed all but unfortunately no getting expected result. I have followed till end of step Install Systemd Unit File in this link. Is there any problem in setting JAVA_HOME? I followed answer in this link. But not getting expected result. Every time I check tomcat status , I get this

tomcat.service - Apache Tomcat Web Application Container

And in cataliina.out trace is

OpenJDK 64-Bit Server VM warning: If the number of processors is expected to increase from one, then you should configure the number of parallel GC threads appropriately using -XX:ParallelGCThreads=N
  • Can you add the output of journalctl -u tomcat.service to the question? – Haxiel Jan 20 at 7:55
  • @Haxiel I updated my question. Can you please check? – Avijit Barua Jan 20 at 8:24
  • Thanks, but it looks like the logs are being written elsewhere, and not to the systemd journal. Can you look for the directory /opt/tomcat/logs in your system and see if you can find any information there? There should be a log file with the name catalina, which is Tomcat's standard log. – Haxiel Jan 20 at 8:32
  • @Haxiel, Yes , there it is ! – Avijit Barua Jan 20 at 8:34
  • Since the server is failing to start, that log should contain some error messages for you to check further. You can also post the logs from the last startup here, so that we can check. – Haxiel Jan 20 at 8:36
