Hi folks! Is it possible when using s6-svscan/s6-supervise to somehow arrange so that a daemon’s stdout is sent to one logdir and stderr to another logdir?
Or must I use s6-rc in order to achieve this? My premises are the following: I want to run nginx under s6, on a mainstream Linux distro such as Debian/Ubuntu/CentOS. My plan is currently to use s6 only for nginx and not any other daemons. I want to collect the web server access logs in order to generate visitor statistics[1]. One tricky aspect of logging that is specific to web servers is that they emit two different categories of messages: a) Errors and warnings b) Info about page requests[2] For many other kinds of daemons, one only needs to arrange for logging stderr and then call it a day. With web servers it’s not quite so simple. I am very interested to hear from others on the list what your thoughts are about this scenario. The reason I’m weary about s6-rc is that I think it might not play so well with the distros I mentioned earlier. If this concern is not correct, please let me know. [1] An alternative to collecting access logs could be to use Google Analytics instead, but I want to avoid that since I don’t feel comfortable about handing over my visitors’ personal data over to Google. [2] I.e. lines like this '10.131.214.101 - - [20/Nov/2017:18:52:17 +0000] "GET / HTTP/1.1" 401 188 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:47.0) Gecko/20100101 Firefox/47.0"'
