Re: [VuFind-Tech] Help needed with solr-log-rotation

[Ere M. <ere...@he...>]

I'd suggest configuring Solr to rotate the logs, so you won't need 
logrotate at all. Solr can use SLF4J (up to version 4.2.1) or a 
selectable logging facility (from 4.3), and you can configure it to 
rotate logs. Without any configuration it seems logging will go to 
standard output, which means that in VuFind everything ends up in 
wherever JETTY_CONSOLE points to, but setting up SLF4J lets Solr logging 
output to go somewhere else.

I don't usually run VuFind's default Solr, but it seems to have a sample 
logging.properties file in solr/jetty/etc. You could modify (a copy of) 
it and add a line like this:

java.util.logging.FileHandler.count = 10

This means rotation keeps 10 files. Note that the default log directory 
in logging.properties is ./logs, so create it or change 
java.util.logging.FileHandler.pattern as necessary. Then specify the 
logging configuration when starting Solr like this (or modify your 
startup script accordingly):

JAVA_OPTIONS="-Djava.util.logging.config.file=solr/jetty/etc/logging.properties" 
./vufind.sh start

Hope this helps, but if I was unclear, feel free to ask for clarification!
