Where is a log file of passenger

Question

My rails application doesn't response for the address I configured in nginx (No data response. Error 324 (net::ERR_EMPTY_RESPONSE)). Now I'm trying to figure out what the problem could be. Nginx log has per request:

libc++abi.dylib: terminate called throwing an exception 2013/10/21 15:15:30 [alert] 54636#0: worker process 54723 exited on signal 6

If I look into application log - there is no changes, looks, like passenger didn't request something from the app. So I though about another log files, where I could gather some information.

Where does passenger locate its log file?

Is there any special? Or does passenger use one of the application logs?

In Linux, you can find your log files under

/var/log/nginx/access.log
/var/log/nginx/error.log

I had to restart my Ubuntu server before I could actually see what Passenger was writing to these files, FWIW... – croceldon Sep 21 '22 at 16:17

Thank you. This helped me find my passenger-error.html file that had the log message I needed to view. – Kody_06 Jan 19 '22 at 15:22

Old question, just for the records:

By default Passenger log messages are written to the Nginx global error log.

This exert comes from a recent version. It may not apply before Passenger 5.0.5.

This is totally applicable to versions before 5.0.5. It is applicable to all versions. – Hongli Aug 31 '15 at 03:28

Passenger prints its own logs not only to the terminal, but also to a log file. During startup, Passenger tells you what log file it used. This is typically log/passenger.XXXX.log. see

https://www.phusionpassenger.com/docs/tutorials/quickstart/ruby/

mine was[3000 was port number for the app] less {app_dir}/log/passenger.3000.log

if the passenger crashes, it shows on the console & passenger.xxxx.log the directory where the log files are

[ pid=2659 ] Crash log files will be dumped to /var/tmp/passenger-crash-log.1583439070.ZfMXhF <--- ******* LOOK HERE FOR DETAILS!!! *******
