Deleted /tmp/ files and getting 502
I accidentally the files in my tmp folder and now I am getting a 502 error on all of the sites running on my server.
Getting the following error in my error.log
2017/06/23 12:21:00 [crit] 17256#0: *1 connect() to unix:/var/run/php/php7.0-fpm.sock failed (2: No such file or directory) while connecting to upstream, client: 220.127.116.11, server: boss-14-001.bareface.work, request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.0-fpm.sock:", host: "boss-14-001.bareface.work", referrer: "http://boss-14-001.bareface.work/"
I also get the following in my syslog
I am very new at this so if you can help, please be as clear as possible. As far as I can see I may have deleted php7.0-fpm.sock but not sure how to restore that.
