I had to integrate websites that used Nginx and php into other web servers. This content describes the process of resolving errors that occurred during Web server consolidation.

 

 

First, I checked the versions of Nginx and php.

Before integrating the web server, I matched the same version of Nginx and php. However, when I checked the php version, php was activating the existing version, and I upgraded the version in a new way.

 

How to upgrade PHP version:

The same version of Nginx and php were matched, but the same error occurred. So I reinstalled php-fpm. But the result was same.

// Check package name
# yum list php*fpm

// Remove
# yum remove php70w-fpm -y

// Reinstall
# yum install php70w-fpm -y

 

And I check the path of php-fpm again,

NGINX: connect() to unix:/var/run/php7.2-fpm.sock failed (2: No such file or directory)

 

Finally, it was resolved through LISTEN value modification and permission setting.

/etc/php-fpm.d/www.conf

[www]
;user = apache
user = nginx
;group = apache
group = nginx

;listen = 127.0.0.1:9000
listen = /var/run/php-fpm/php-fpm.sock

;listen.owner = nobody
listen.owner = nginx
;listen.group = nobody
listen.group = nginx
listen.mode = 0660

# systemctl restart nginx php-fpm
