maas-http service changing perms on system nginx paths

[Joshua McClintock]

I see this option set in /var/lib/maas/http/nginx.conf:

    # LP: #1796224 - Use a different path otherwise this will
    # conflict with the system's nginx daemon.
    client_body_temp_path /var/lib/maas/http/body;

However, there are 4 other paths which need to be added as well.

   proxy_temp_path /var/lib/maas/http/proxy;
   fastcgi_temp_path /var/lib/maas/http/fastcgi;
   scgi_temp_path /var/lib/maas/http/scgi;
   uwsgi_temp_path /var/lib/maas/http/uwsgi;

Here is what happens if they aren't.

1. Correct perms on system nginx

root@node:/var/lib/nginx# ls -la
total 28
drwxr-xr-x 7 root root 4096 Oct 2 16:18 .
drwxr-xr-x 50 root root 4096 Nov 27 10:13 ..
drwx------ 2 www-data root 4096 Oct 2 16:18 body
drwx------ 2 www-data root 4096 Oct 2 16:18 fastcgi
drwx------ 9 www-data root 4096 Mar 10 14:49 proxy
drwx------ 2 www-data root 4096 Oct 2 16:18 scgi
drwx------ 2 www-data root 4096 Oct 2 16:18 uwsgi

2. Restart maas-http service and perms get changed on the other 4 dirs

root@node:/var/lib/nginx# service maas-http restart
root@node:/var/lib/nginx# ls -la
total 28
drwxr-xr-x 7 root root 4096 Oct 2 16:18 .
drwxr-xr-x 50 root root 4096 Nov 27 10:13 ..
drwx------ 2 www-data root 4096 Oct 2 16:18 body
drwx------ 2 nobody root 4096 Oct 2 16:18 fastcgi
drwx------ 9 nobody root 4096 Mar 10 14:49 proxy
drwx------ 2 nobody root 4096 Oct 2 16:18 scgi
drwx------ 2 nobody root 4096 Oct 2 16:18 uwsgi

3. Restart system nginx and they go back to normal

root@node:/var/lib/nginx# service nginx restart
root@node:/var/lib/nginx# ls -la
total 28
drwxr-xr-x 7 root root 4096 Oct 2 16:18 .
drwxr-xr-x 50 root root 4096 Nov 27 10:13 ..
drwx------ 2 www-data root 4096 Oct 2 16:18 body
drwx------ 2 www-data root 4096 Oct 2 16:18 fastcgi
drwx------ 9 www-data root 4096 Mar 10 14:49 proxy
drwx------ 2 www-data root 4096 Oct 2 16:18 scgi
drwx------ 2 www-data root 4096 Oct 2 16:18 uwsgi
