iptables

Turn off iptables:

/etc/init.d/iptables stop

If it helps - fix iptables rules or uninstall iptables (not recommended).

How to fix iptables rules - check iptables manual or better - consult specialist.



DB settings

Something went wrong.jpg

If you get such error - that means GUI cannot connect to DB.

Check /home/mor/config/database.yml and correct DB settings in [production] section.




Apache cannot start

Apache log /var/log/httpd/error_log shows:

No space left on device: mod_rewrite: could not create rewrite_log_lock Configuration Failed

Checking your disk shows that you have plenty of space. The problem is that apache didn't shut down properly, and it's left myriads of semaphore-arrays left, owned by my apache-user. Run:

ipcs -s | grep apache | perl -e 'while (<STDIN>) { @a=split(/\s+/); print `ipcrm sem $a[1]`}'

Restart Apache:

/etc/init.d/httpd restart

Reason for this problem: unknown

Upgrade DB by running appropriate fix script.

Error 503 when opening GUI


After you perform upgrade on server, you get 503 error when opening GUI.
In server /var/log/httpd/error_log
You see a lot of:

[error] (13)Permission denied: mod_fcgid: couldn't bind unix domain socket /etc/httpd/logs/fcgidsock/8060.11    


[warn] (13)Permission denied: mod_fcgid: spawn process /var/www/html/billing/dispatch.fcgi error


This means that permission are mixed up, solution:

chmod 555 /etc/httpd/logs (this is a symlink to /var/httpd/logs)
