Why is the PHP-FPM socket missing?

Question

PHP

Hello! For some reason, installing PHP7.0-FPM causes a 503 Service Unavailable error on all sites.
In the Apache error logs I see:

[Tue Dec 06 11:04:38.773138 2016] [proxy:error] [pid 1586] (2)No such file or directory: AH02454: FCGI: attempt to connect to Unix domain socket /run/php/php7.0-fpm .sock (*) failed
[Tue Dec 06 11:04:38.773250 2016] [proxy_fcgi:error] [pid 1586] [client 127.0.0.1:49379] AH01079: failed to make connection to backend: httpd-UDS

As my ISP told me, the errors indicate no socket from PHP7. How to fix this error?

Answer 1

edit config /etc/php/7.0/fpm/pool.d/www.conf
listen = /run/php/php7.0-fpm.sock
