Permission Denied for fastcgi_pass using PHP7

I'm running LEMP with PHP7.0.

I've got this in my server block

fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;

But when I open the site, it returns a 502 Bad Gateway. Below is the error log.

*1 connect() to unix:/var/run/php/php7.0-fpm.sock failed (13: Permission denied) while connecting to upstream, client: xxx.xxx.xxx.xxx, server: example.com, request: "GET / HTTP1.1", upstream: "fsatcgi://unix:/var/run/php/php7.0-fpm.sock:", host: "example.com"

It says Permission Denied. What's wrong here? I've checked but I can't seem to find what needs to be given what kind of permission.

Thank you.

Solution 1:

I got it working.

The php user was www-data but the nginx user was nginx.

Check php here: /etc/php/7.0/fpm/pool.d/www.conf

listen.owner = www-data
listen.group = www-data
listen.mode = 0660

Nginx user was at /etc/nginx/nginx.conf

Solution 2:

I have fixed same issue by taking following steps.

Open your www.conf files (Example : sudo nano /etc/php-fpm.d/www.conf) Lastly, find the lines that set the listen.owner and listen.group and change their values from "nobody" to "nginx":

listen.owner = nginx
listen.group = nginx
listen.mode = 0660

Lastly, find the lines that set the user and group and change their values from "apache" to "nginx":

user = nginx
group = nginx

Restart php-fpm (sudo service php-fpm restart)
