for start you can change max_children for your php-fpm.
what happens if you remove/rename .htaccess ?
Hello,
Thank you for your support parzival
I increased the max from 8 to 20 for all the websites. Now I am getting max_children error for NextCloud Website only. Should I increase max_children even more?
[18-Sep-2020 20:06:32] WARNING: [pool NEXTCLOUD.WEBSITE] server reached max_children setting (20), consider raising it
I also increased the MaxRequestWorkers located at /etc/apache2/mods-enabled/mpm_event.conf from 150 to 250 after getting this error
[mpm_event:error] [pid 758:tid 139953702136896] AH00484: server reached MaxRequestWorkers setting, consider raising the MaxRequestWorkers setting
[mpm_event:error] [pid 758:tid 139953702136896] AH10159: server is within MinSpareThreads of MaxRequestWorkers, consider raising the MaxRequestWorkers setting
I have multiple users with different permissions, .htaccess is controlling users permissions. I am afraid deleting the .htaccess will severely affect the site.
I appreciate the support.

Nasser
For sure, you can play with those settings, but from my personal experience, blindly increasing default settings might, in some cases, result in unstable system. First thing to do is to try and get rid off the errors and then when you finally find out whats wrong, try to optimise your VPS.
Are you still getting .htaccess not being readable? When I said to remove .htaccess I ment to rename it to .htaccess.bak for testing. Just to make sure if its the htaccess thats making funny things. And that did happened before.
I know that changing things on live server is never good idea but its not always possible to have spare VPS to play with before going into production.

That’s correct. I will not increase max_children any more because I not sure how to calculate the optimal value for my VPS.
I have renamed the file to .htaccess.bak, then I restarted the server and added users with different permissions. I didn’t had any problems.
However, I am still getting the error on the /var/log/apache2/domains/DOMAIN.error.log

I am not sure how to fix this…
does your “data” folder has x bit set? just go to :
/home/USER/web/NEXTCLOUD.WEBSITE/public_html/
and do : ls -l in console , post results here.
I believe this is pure permission problem and nothing more.
This is the result
root@XXXXXXXXXX:~# cd /home/USER/web/NEXTCLOUD.WEBSITE/public_html/
root@XXXXXXXXXX:/home/USER/web/NEXTCLOUD.WEBSITE/public_html# ls -l

can you go to :
/home/USER/web/NEXTCLOUD.WEBSITE/public_html/
and do : chmod 755 data/
When I change the permission to 755 it reverte to 770.
I see, its default behaviour. I forgot to re-read the whole thread.
Ok, this is a bit different.
can you check if apache has acces to that folder:
su - www-data -s /bin/bash -c “cd /home/USER/web/NEXTCLOUD.WEBSITE/public_html/data/; ls -la”
cat you put whole line :
su - www-data -s /bin/bash -c “cd /home/USER/web/NEXTCLOUD.WEBSITE/public_html/data/; ls -la”
and not just : cd /home/USER/web/NEXTCLOUD.WEBSITE/public_html/data/; ls -la
the reason for this is to see if there is something wrong with default installation.
Also on my setup I have these permissions on folders starting at home folder:
home/ root.root
/home/user/ root.root permission 755
/home/user/web/ user.user permission 751
home/user/web/website.com/ user.user permission 751
/home/user/web/website.com/public_html/ user.www-data permission 751
Thank you for your support parzival. Here is the output
root@ADMIN:~# su - www-data -s /bin/bash -c ‘cd /home/USER/web/NEXTCLOUD.WEBSITE/public_html/data/; ls -la’ -bash: line 0: cd: /home/USER/web/NEXTCLOUD.WEBSITE/public_html/data/: Permission denied total 20

Ok. I think we are getting somewhere. It seems that www-data user aka apache cant reach your data directory.
can you do :
ls -l /home/USER/web/NEXTCLOUD.WEBSITE/
I really appreciate your support.

and ls -l /home/USER/web/
is something like
drwxr-x–x USER USER NEXTCLOUD.WEBSITE
right?

I think you have two solutions for your problem, and I hope others will chime in:
- You can add www-data user to your USER group like:
usermod -a -G USER www-data - use setfacl like this:
cd /home/USER/web/NEXTCLOUD.WEBSITE/public_html/
setfacl --modify user:www-data:x data/ <— this is copy/paste line. user in this line is a statement so dont change user with your username. LIke I said just copy/paste this line.
Note: I hope some hestia admin will see this before we do something stupid. Personally I cant think of a single reason that we can mess things up, but it would be nice if someone made, perhaps, more elegant solution for this problem.

parzival thank you for your support. I used the second solution.
I will keep monitoring but should I rename .htaccess.bak to .htaccess or no need for that?
You should be able to use .htaccess, and It would be nice to report if everything works like it should.
Thank you parzival, I am no longer getting the error. I believe the problem has been fixed.
I have also increased the max_children again from 20 to 40. After the increase I have noticed improvement in performance and speed. Now the preview of the large PDF files is showing up instantly.
I really appreciate the support from you and everyone here.
