As the title says, I have a server where nginx was originally installed by the root user. I now want to run nginx as a non-root user, a new user that I added to both the sudo the www-data groups.
When I try to run nginx from this new user, I get the following message:
nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (13: Permission denied)
2016/08/09 22:07:52 [warn] 17609#0: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1
2016/08/09 22:07:52 [emerg] 17609#0: open() "/var/log/nginx/access.log" failed (13: Permission denied)
I’m confused why this is an issue—I changed the owner and group of /var/log/nginx/ to www-data. The nginx master process user is root, which I believe is correct, and the sub-processes are running (or trying to run) as www-data. The file permissions for error.log and 'access.log` are 755. What am I missing?

I received some advice that solved my problem and seems to be sound counsel. I’m now starting the server from the non-root account using sudo and all is well. One little trick!
Your Nginx web-user isnt permitted to access the logs. Modify the permissions with:
sudo chown -R www-data:www-data /var/log/nginx;
sudo chmod -R 755 /var/log/nginx;
possible right answer is: sudo nginx -t try nginx self check from sudo user.
