Hi, I am running CentOS Linux release 7.8.2003 (Core) with php72u-fpm-7.2.30-1.el7.ius.x86_64 version. I am facing the below permission denied issue. I also did the below steps #cd /run #chown -Rc nginx.nginx php-fpm changed ownership of ‘php-fpm/php-fpm.pid’ from root:root to nginx:nginx changed ownership of ‘php-fpm’ from root:root to nginx:nginx #systemctl restart php-fpm again changes it from nginx.nginx to root.root user. nginx error logs > 2020/04/30 03:09:28 [crit] 17175#0: *154570 connect() to > unix:/run/php-fpm/www.sock failed (13: *Permission denied*) while > connecting to upstream, client: 49.207.54.161, server: _, request: "GET / > HTTP/1.1", upstream: "fastcgi://unix:/run/php-fpm/www.sock:", host: > "35.128.212.112" > 2020/04/30 03:09:28 [error] 17175#0: *154570 open() > "/var/www/drupal/web/50x.html" failed (2: No such file or directory), > client: 49.207.54.161, server: _, request: "GET / HTTP/1.1", upstream: > "fastcgi://unix:/run/php-fpm/www.sock", host: "35.128.212.112" > 2020/04/30 03:09:35 [crit] 17176#0: *154573 connect() to > unix:/run/php-fpm/www.sock failed (13: Permission denied) while connecting > to upstream, client: 49.207.54.161, server: _, request: "GET / HTTP/1.1", > upstream: "fastcgi://unix:/run/php-fpm/www.sock:", host: "35.128.212.112" > 2020/04/30 03:09:35 [error] 17176#0: *154573 open() > "/var/www/drupal/web/50x.html" failed (2: No such file or directory), > client: 49.207.54.161, server: _, request: "GET / HTTP/1.1", upstream: > "fastcgi://unix:/run/php-fpm/www.sock", host: "35.128.212.112" > 2020/04/30 03:09:49 [crit] 17175#0: *154575 connect() to > unix:/run/php-fpm/www.sock failed (13: Permission denied) while connecting > to upstream, client: 14.98.153.6, server: _, request: "GET / HTTP/1.1", > upstream: "fastcgi://unix:/run/php-fpm/www.sock:", host: "35.128.212.112" > 2020/04/30 03:09:49 [error] 17175#0: *154575 open() > "/var/www/drupal/web/50x.html" failed (2: No such file or directory), > client: 14.98.153.6, server: _, request: "GET / HTTP/1.1", upstream: > "fastcgi://unix:/run/php-fpm/www.sock", host: "35.128.212.112" > 2020/04/30 03:09:50 [crit] 17175#0: *154575 connect() to > unix:/run/php-fpm/www.sock failed (13: Permission denied) while connecting > to upstream, client: 14.98.153.6, server: _, request: "GET / HTTP/1.1", > upstream: "fastcgi://unix:/run/php-fpm/www.sock:", host: "35.128.212.112" > 2020/04/30 03:09:50 [error] 17175#0: *154575 open() > "/var/www/drupal/web/50x.html" failed (2: No such file or directory), > client: 14.98.153.6, server: _, request: "GET / HTTP/1.1", upstream: > "fastcgi://unix:/run/php-fpm/www.sock", host: "35.128.212.112" > 2020/04/30 03:10:46 [crit] 17176#0: *154578 connect() to > unix:/run/php-fpm/www.sock failed (13: Permission denied) while connecting > to upstream, client: 184.22.107.148, server: _, request: "GET / HTTP/1.1", > upstream: "fastcgi://unix:/run/php-fpm/www.sock:", host: "35.128.212.112" > 2020/04/30 03:10:46 [error] 17176#0: *154578 open() > "/var/www/drupal/web/50x.html" failed (2: No such file or directory), > client: 184.22.107.148, server: _, request: "GET / HTTP/1.1", upstream: > "fastcgi://unix:/run/php-fpm/www.sock", host: "35.128.212.112" Please let me know if you need any additional information.
