we are trying to setup open on demand on ubuntu 22.04 .My question in short is : do we need to apt install a lua interpreter ?
In long , we are facing some issues, we believe are related to proxy handling in the apache2 setup which appears to me handled by lua scripts from /opt/ood/mod_ood_proxy/lib. I’m not yet sure these scripts are correctly running.
But, what I do not know is how to debug such issues; I would expect to see some errors in the apache2 logs in /var/log/apache2 , but I do not see such things as “cannot find lua interpreter” or so ;
Is there some apache2 options to change to raise the log level ? Or maybe such error is raised somewhere else ?
My question is really general and more related to apache2 I believe;
When, for example mod_lua is running, for example when running node_proxy.lua , where these processes logging ? Actually there is a LogLevel lua_module:info in the apache2 conf script and there I would expect these logs to appear somewhere. Are these expected to be in the logs located in /var/log/apache2/ ?
