7.9 upgrade won't start

I have too problem with upgrading to sonarqube 7.9 (from 6.7…). I get basically the same log messages as in the previous post, but also “max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]”. I have increased, ulimit -n says “65535” but ElasticSearch doesn’t see that. You also write about MySQL, I have MySQL installed, but I don’t just want to uninstall it?


If your logs say that SonarQube/Elasticsearch doesn’t have access to enough processes, then that’s actually the problem. I know from personal experience that getting this set correctly can be tricky, but it’s really a Linux sysadmin thing at this point.

Regarding MySQL, you don’t have to uninstall it from your system, you just can’t use it with SonarQube anymore.
