where is the output log found on a Linux headless server?
I'm running Unity Pro 4.1.3 (Unity editor is on my Windows 7 laptop), and have built a Linux x86_64 architecture binary for use on my Amazon EC2 Fedora 64-bit server.
I've uploaded both the executable (with chmod +x on it so it executes) and the data folder into my home folder. I'm using the following command line to instantiate the server (the server app is called "zone1"):
xvfb-run --auto-servernum --server-args='-screen 0 640x480x24:32' ./zone1 -batchmode -nographics
The output is as follows:
Set current directory to /home/ec2-user/unity
Found path: /home/ec2-user/unity/zone1
Mono path[0] = '/home/ec2-user/unity/zone1_Data/Managed'
Mono path[1] = '/home/ec2-user/unity/zone1_Data/Mono'
Mono config path = '/home/ec2-user/unity/zone1_Data/Mono/etc'
/usr/bin/xvfb-run: line 166: 23189 Aborted DISPLAY=:$SERVERNUM XAUTHORITY=$AUTHFILE "$@" 2>&1
I've looked in /var/log and found nothing. I've also looked for an output.txt in the zone1_Data folder (as it is when I run the windows version on a windows server). No joy. Is there a log file somewhere that will tell me what is going on, or is it just this console output?
After some further investigation, I have some more information, as well as a workaround.
First of all, apparently Unity 4.1 no longer requires the use of xvfb-run. This simplifies the command line somewhat, and probably also eliminates some overhead/dependencies that could cause issues.
Secondly, I've discovered that the linux command line also takes an optional "-logfile " argument (although it is implied that it only works on Windows on http://docs.unity3d.com/Documentation/Manual/CommandLineArguments.html). So I can now work around the original problem and view the logfile as follows:
./zone1 -batchmode -nographics -logfile zone1_output_log.txt
This effectively answers my original question, although I'm still curious as to where the default location of the logfile is in linux. Anyone know?
You can find the log here:
~/.config/unity3d
Thanks for your answer, but I have no such folder. Also, I am no longer using Fedora, and have switched the server over to Ubuntu. Not sure if that makes a difference.
In any case, I'm able to manually place my log using the '-logfile' argument, so this isn't really an issue.
Odd that it's not there for you as it's there for me on both Debian 7 (wheezy) and Ubuntu 12.04 LTS (Precise Pangolin)
Just to be clear '~' is your home directory and the '.config' folder will be hidden as it beings with a '.'.
Thanks for the clarification, but I'm already aware about '~' being an alias for my home dir, and '.' prefix "hidden" files, being an old school unix ad$$anonymous$$ for 20+ years.
I'm also running 12.04 LTS.
Perhaps it's not there because I'm using the '-logfile' argument. I spent some time modifying my config files to start the server without it, but it didn't create that folder, so I just changed it back.
I'd say just don't worry about this. It's preferable to use a specific logfile location of my choice anyway. It's not worth the effort to troubleshoot.
For some reason this is both true and false. There is a log file there, but it does not contain "all the logs" I don't know why, but if you pass the command line -logfile then you get "all the logs messages"
