Respected, I’m facing php7.0-fpm.sock failed error from a long time on Ubuntu 16.04.5 LTS (NGINX). Six websites are active on this server.
Kindly check below detailed logs.
php7.0-fpm.log:
2018/09/04 06:25:04 [error] 18209#18209: *362673 connect() to unix:/run/php/php7.0-fpm.sock failed (11: Resource temporarily unavailable) while connecting to upstream, client: 162.158.126.43, server: [domain_name_hidden].com, request: “GET / HTTP/1.1”, upstream: “fastcgi://unix:/run/php/php7.0-fpm.sock:”, host: “[domain_name_hidden].com”

Getting 502 Bad Gateway error while opening websites link.
If reboot the server then websites are working for a limited period (Approximately 5-7 hours). Another fix, I need to restart the PHP FPM through the following command: sudo service php7.0-fpm restart
Please help. Thank you!

I have changed root from unix:/run/php/php7.0-fpm.sock to unix:/var/run/php/php7.0-fpm.sock in Nginx Conf and Sites-available files for the testing purpose. I’ll update soon if the error appears again.
Here’s a summary of what fixed this error: In /etc/php/7.0/fpm/pool.d/www.conf change the lines as below: listen = /var/run/php/php7.0-fpm.sock In /etc/nginx/sites-available/your_site.conf: Under “location ~ .php$ {” change the line to: fastcgi_pass unix:/var/run/php/php7.0-fpm.sock; Restart nginx: sudo service nginx restart Everything should then work.
I had this same problem and seemed to have fixed it.
Details:
Like chinmayrajyaguru, I changed
unix:/run/php/php7.0-fpm.socktounix:/var/run/php/php7.0-fpm.sock. However, I changed/etc/php/7.2/fpm/pool.d/www.conf.Upon doing that (and without restarting nginx or php-fpm), I refreshed the page which was displaying the 502 error and it immediately went back to normal.
To the best of my knowledge, you need to make sure the unix socket path is the same in your nginx site config and the php-fpm pool config.
Hope this helps anyone with this issue. I will post again if this isn’t a permanent fix.
