Nginx Bad Gateway

[Alex12345678910]

Hi,

Someone decided to chmod -r the entire server yesterday. we have restored all the web and database permissions and these are now working.

When we try and login to the server we get a 502 bad gateway nginx... whne we look at the logs we see:

2015/10/07 08:09:25 [crit] 6197#0: *177 connect() to unix:/var/run/sw-engine.sock failed (13: Permission denied) while connecting to upstream, client: 31.53.107.164, server: , request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/sw-engine.sock:", host: "212.48.87.9:8443"

Any ideas on how to repair or fix permissions for this?

Thanks

Hi Alex12345678910,

first, please have a look at: [IMPORTANT]: READ THIS FIRST TO FIND QUICK SOLUTION FOR THE EXISTING ISSUE/QUESTION

You will find as well a link to the Odin - Knowledge-Base, where you have a search option. Searching would point to for example:

[HUB] Troubleshooting "502 Bad Gateway" error ( KB - article 124 377 )
and
[HUB] Unable to login to Plesk ( KB - article 126 564 )
​

Investigations should be done with the help of logs. Please visit and bookmark:

Odin / Parallels Plesk Panel for Linux services logs and configuration files ( KB - article: 111 283 )​

Services

• Stop: /etc/init.d/psa stop
• Start: /etc/init.d/psa start
• Restart: /etc/init.d/psa restart

Please use these commands and report further issues.


Sometimes, it is as well a good idea to change the log - level, to get more informations in psa - log - files:

How to enable/disable debug logging in Plesk 11.5 and up? ( KB - article 120 101 )​

Another way to find, solve and/or repair issues, is to use the "bootstrapper repair utility" ( for Plesk 12.5, you should use the "Plesk Self Repair Utility" ) :

/usr/local/psa/bootstrapper/pp12.0.18-bootstrapper/bootstrapper.sh repair​

If you experience issues/problems and need help with the investigations, please consider to post the corresponding - log - file(s).
