[misterzik]

Getting 500 on prod server running ubuntu, apache, php 7.0 ..

Here is the virtual host info, mod_rewrite is enable,

Did you already try the "usual suspects" for 500 errors? https://learn.getgrav.org/troubleshooting/internal-server-error

[misterzik]

Yup already tried, thanks for your response tho, I am on a virtual host environment running apache and Ubuntu.

I am afraid the problem might be that I'm using PHP 7.0, anyone using 7 successfully?

[flaviocopes]

We're all (dev team) using PHP 7 since its pre-releases, no issue with it.

Is there something in the PHP error log?

[misterzik]

Thanks for the reply @flaviocopes

Ok looks like a permissions problem on the cache folder, see https://learn.getgrav.org/troubleshooting/permissions

[misterzik]

Thanks a lot! indeed was permission problems and corrupted dependencies. After trying again the permison part, nothing changed.

#!/bin/sh
chown myuser:staff .
chown -R myuser:staff *
find . -type f | xargs chmod 664
find ./bin -type f | xargs chmod 775
find . -type d | xargs chmod 775
find . -type d | xargs chmod +s
umask 0002

Since you point at the cache folder, i went ahead and chmod -R 0777 cache/ just for kicks, and i was able to advanced to the next screen-shot, in the page - Issues Found Please Review and Resolve before continuing... I was able to see the dependencies that got corrupted, and re-installed them succesfully.

After that i am still getting the error page and now it says;

/var/www/web.org/public_html/cache exists but is not writeable

/var/www/web.org/public_html/logs exists but is not writeable

/var/www/web.org/public_html/images exists but is not writeable

/var/www/web.org/public_html/assets exists but is not writeable

/var/www/web.org/public_html/user/data exists but is not writeable

/var/www/web.org/public_html/backup exists but is not writeable

/var/www/web.org/public_html/tmp exists but is not writeable

The only way so far i have found to by pass this error is to set those folder to find . -type d -exec chmod -R 0777 {} \; for time being, instead of 775 like it says on the site. I strongly feel this is not secure, i will try to lower permission on directory folders after installation to see if it works.

[misterzik]

I was able to figure it out, The problem was a server misconfiguration. But for sakes of other people time, i was given an ssh account with a non-root user but added to the sudo groups.

I created the bash script as instructed on the documentation and ran it.
nano perms.sh then;

#!/bin/sh
chown MyUser:MyUser .
chown -R MyUser:MyUser *

find . -type f | xargs chmod 664
find ./bin -type f | xargs chmod 775
find . -type d | xargs chmod 775
find . -type d | xargs chmod +s

umask 0002

After running it and heading to the site, i will get 500 error, all php mods were enable, as well has .htaccess. The problem for me was, i was giving a non-global user.

To find which user apache was running on, i did ps aux | egrep '(apache|httpd)' to then find my global user was www-data .....

So changed back the script to the proper user, and website its working great now! thanks!

Hello,

I had a similar error and it was because of file permissions.

In the documentation, on permissions page I found that the following line was confusing, I didn't get the humour:
chown -R joeblow:staff .

I would rather prefer something more direct like
chown -R myuser:www-data .
or
chown -R myuser:http .

Many thanks!
