(For interactive linguistic analysers’ malfunctioning, see the bottom of the page)
This is the server with the web address gtweb.uit.no. It runs the interactive services of Giellatekno and Divvun, most notably machine translation, corpus search (Korp) and the grammatical analysis on http://giellatekno.uit.no (running cgi-bin scripts).
On gtweb-01, two httpd services are used. nginx is the primary system
for serving all projects, however apache/httpd is used to run certain CGI
and MT scripts which Nginx does not have support for. This is done via
reverse proxy. apache/httpd thus doesn’t run on port 80, rather
nginx does, and certain requests are passed off to apache
internally.
Try (e.g.) http://jorgal.uit.no (write “ja” and translate, the answer should be “og”). If you get no answer, the system is malfunctioning.
Check whether apy runs and look at the log:
ssh gtweb # log into gtweb
sudo journalctl -u apy -n100 # 100 last lines
When things are working, you should get strings in some Saami language. When things are not working, you could e.g. get a message saying that the disc is full. This is the most likely error, as the disc has only 111GB space (TODO: ask IT to get a bigger one). When the disc is full other things could go wrong. Have a look at that:
systemctl --state=failed
If the disc is full, at least the following files may be removed (followed by a restart of apy:
sudo rm -rf /var/cache/apy/* # remove files (be careful with sudo and -rf!
sudo systemctl restart apy # restart apy
On gtweb-01, if for some reason the processes do not restart via chkconfig, inspect via
ps aux
or
top
to find out what is or isn’t running.
Once missing processes have been identified, the proper order that all services should be started in (given dependencies between them) is:
For this use the command
sudo service NAME start
, or alternatively restart, if necessary.
sudo service mysqld start
sudo service nginx start
sudo service httpd start
etc...
For further documentation on this, see the various sections in common httpdserver.
Restart is still not documented (but see above), but have a look at the page for installing mt on gtweb
The following documentation was taken from the old victorio documentation, but may be relevant for gtweb-01 as well: (TODO: check)
Updates to the code require restart of the httpd-server. Sometimes updates to the localisation require that too. The restart is otherwise harmless, but may distrub someone who is playing the came (although that is not very probable).
Restarting the server (requires sudo rights):
sudo /etc/init.d/httpd restart
Earlier, there was a memory leak problem, which should not be among us anymore. However if victorio is very slow, check the memory by writing:
ps aux | grep http
If the result indicates memory use too close to 100, this is a clear problem indication. The answer is to restart the apache web server, and thereafter, if need, to restart mysqld.
If the webserver takes too much memory, you may also want to stop apache first, and then myql, and then starting them again:
sudo /etc/init.d/httpd stop
sudo /etc/init.d/mysqld stop
sudo /etc/init.d/httpd start
sudo /etc/init.d/mysqld start
sudo service eXist-db start
A server reboot should not affect the web servers. After the reboot, the web servers are automatically running again.
Eventual malfunctioning here is due to errors in the pipeline being used by the analysers. The documentation is found on the cgi-bin documentation page
The jorgal.uit.no page may give the message Oversettelse ikke tilgjengelig!
This command should help:
ssh -t gtweb
sudo systemctl restart apy
