[Help]Domjudge on CentOS
Dear admin, I am a student at University of Information Technology, I'm going to use Domjudge to organize our contest (ACM), I followed your Admin Manual Installation Guide, but I always get error when install Domjudge: -- Before, I get error about jsoncpp-devel. Then, I add --disable-submitclient in configure line. This was not happened. -- After, when I run make, I get error about symbol in /usr/lib/libm.so. File in wrong format. -- Then, I followed Install again, I check url /share/domjudge/www/jury => it a white page. I think I have some mistake when install, but I sure that I followed all of you tutorial. So, can you help me to install this? I'm using CentOS 6.7 with Kloxo installed.

I don't understand your last sentence. Do you mean that adding --disable-submitclient fixed the error?
-- After, when I run make, I get error about symbol in /usr/lib/libm.so. File in wrong format.
What is the exact error message? Which version of DOMjudge are you using?
-- Then, I followed Install again, I check url /share/domjudge/www/jury => it a white page.
First of all, you should browse to http://localhost/domjudge or something similar depending on what setup for apache you used. Did you install the apache.conf snippet and configure apache? Then, the best place to look for clues is in the apache error log files.
I think I have some mistake when install, but I sure that I followed all of you tutorial. So, can you help me to install this? I'm using CentOS 6.7 with Kloxo installed.
We have no experience with Kloxo, so I don't know whether domjudge will work with that instead of plain apache2. Best, Jaap
Thank for your reply, -- Before, I get error about jsoncpp-devel. Then, I add
--disable-submitclient in configure line. This was not happened.
I don't understand your last sentence. Do you mean that adding --disable-submitclient fixed the error?
Yes, it fixed error about jsoncpp-devel in CentOS.
-- After, when I run make, I get error about symbol in /usr/lib/libm.so. File in wrong format.
What is the exact error message? Which version of DOMjudge are you using?
Error is /usr/lib/libm.so file in wrong format!
-- Then, I followed Install again, I check url /share/domjudge/www/jury => it a white page.
First of all, you should browse to http://localhost/domjudge or something similar depending on what setup for apache you used. Did you install the apache.conf snippet and configure apache? Then, the best place to look for clues is in the apache error log files.
Because I followed your document, and as your document, I must go to jury folder on my browser, but after I installed domjudge, I can't find out /jury folder in /domjudge (it located in /share/domjudge/www/jury). I sure that apache was install and configure (I can run my site well).
I think I have some mistake when install, but I sure that I followed all of you tutorial. So, can you help me to install this? I'm using CentOS 6.7 with Kloxo installed.
We have no experience with Kloxo, so I don't know whether domjudge will work with that instead of plain apache2.
Because this is a VPS provided by my school's cloud system, so I can't choose OS, it was install CentOS with Kloxo bby default!

Ok, but what is context? Please copy-paste the *exact error output* of make with at least a couple of lines around it. Without the precise file and other possible details, there is very little we can say about this. And what version of DOMjudge do you use?

This is not /domjudge on your filesystem, but a URL as served by your webserver. You should first make sure that your webserver is configured properly and you can view some webpage served from it. Then you have to configure it to include the DOMjudge website tree. The admin manual describes how to do that for Apache, but at least I have no experience with Kloxo (I've never even heard of it before). So unless someone else knows this or you can switch to using Apache, I'm afraid you'll have to figure that out yourself or via other resources.

Then it might be best to try to contact someone at your school who has more experience with configuring this VPS/Kloxo, show them the Apache2 configuration snippet (in etc/apache.conf) and ask if there is a way to configure that in your system. Best, Jaap

Hi Linh, LaTeX is only needed to (re)generate the documentation, but DOMjudge will work fine without that. So you can safely ignore these errors. Jaap On 24-11-15 07:58, Vũ Linh Nguyễn wrote:

Dear Sir,

Indeed, it is noted in the admin manual that jsoncpp-devel is not available on CentOS. You can work around that by disabling the submit client by passing the option --disable-submitclient to configure, or you can try to install the JSONcpp library from source if you want to be able to use the submit client.

Hi Linh,
LaTeX is only needed to (re)generate the documentation, but DOMjudge will work fine without that. So you can safely ignore these errors.

Is the path /home/....... readable for the webserver user? It should probably have world-readable and executable permissions. Also for any subdirs on the path to your DOMjudge directory. (This is more about generic Apache configuration than DOMjudge configuration. You might want to try and Google some on that as there are many results you can find for configuring Apache and problems with that; this might be quicker than waiting for our replies.) Cheers, Thijs

So can I change port of domjudge? Default port is 80, right?
It's no problem for DOMjudge to run on any port you'd like. This is just a matter of changing your Apache configuration (look for the "Listen" directive somewhere under /etc/httpd), and make sure you update the URL in your judgehosts' restapi.secrets file to also include the correct port number. Cheers, Thijs

Dear Sir, I solved this problem, now I can run contest throughly! Everything is OK. But I have a question: I run domserver and judgehost on a same server. So when I start judgedaemon on server, problems submitted will be compiled. So I want to ask that if I can create many judgedaemon on this server? And how can I do this? Because some problems has longer executive time. I only can remote connect to VPS via ssh, and my server is: -- 16CPU Xeon -- Ram 12GB. So can you give me some suggestion for my contest!

Did you enable cgroups as described in the manual? https://www.domjudge.org/docs/admin-manual-3.html#ss3.17 With cgroups (and after the creation of multiple run users), you can start multiple judgedaemons on one machine.

You have to increase the value of MEMRESERVED in the java compile script. It may be necessary that you increase the global memory limit if that's too small. With 64 bit java, it's very difficult to setup without cgroups. Last time, I checked, I had to use 1.3GB for MEMRESERVED with a total memory limit of 2GB to make it work.

Yes, that documentation is a bit debian specific. You have to find out how to change the kernel command line options on CentOS. As a starting point read this: http://serverfault.com/questions/405558/how-do-i-set-the-default-kernel-para...

Again, the documentation is a debian specific. However, it does not really matter, how you create the chroot. So look for other alternatives like https://github.com/dozzie/yumbootstrap Make sure that you install the same java packages inside and outside of the chroot. Cheers, Tobi

Yes, that documentation is a bit debian specific. You have to find out how to change the kernel command line options on CentOS. As a starting point read this:

Again, the documentation is a debian specific. However, it does
not
really matter, how you create the chroot. So look for other alternatives like https://github.com/dozzie/yumbootstrap
Make sure that you install the same java packages inside and outside of the chroot.

Hi, *Vũ Linh Nguyễn <linhnv2110@gmail.com> [15/12/13]:
The output when I login with admin is:
exec: java: not found
The problem is: how can I make chroot work? I setup chroot, and edit CHROOTORIGINAL in chrootstartstop.sh and start it (when I started chrootstartstop.sh, my domjudge directory has etc lib lib64 usr folder like chroot folder), I think chroot must work, but I still can't submit java code.
To check your java installation in the chroot: Did you try (without the use of DOMjudge) - to compile a simple java program outside of the chroot - and to execute the resulting class file in the chroot Best, Tobi
Dear Sir, First: I use chroot /chroot directory to enter chroot environment, then I test java -version and javac -version => it's work. Outside chroot: I compile java with javac hello.java --> java hello => Output: Hello World. Inside chroot: I do as same as. Now I will try to compile java outside chroot, and run it inside chroot! I will reply you later! Thanks for your support Best regard, Linh On Sun, Dec 13, 2015 at 6:10 PM, Tobias Werth <Tobias.Werth@fau.de> wrote:
