Nginx 502 Bad Gateway

joodle

After i rebooted my server, i get the nginx error: 502 Bad Gateway

How can i fix that?

MrAndroid

maybe php-cgi / php-fpm is not running?

service php-cgi start service php-fpm start

joodle

i started php-cgi but still showing that error

Here is a small error log:

2012/09/14 20:17:30 [crit] 810#0: *24 connect() to unix:/var/run/www/php.sock failed (2: No such file or directory) while connecting to upstream, client: XXXXXX, server: XXXXXX, request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://unix:/var/run/www/php.sock:", host: "XXXXX"

@joodle PHP-FPM permissions to that file? http://www.ruby-forum.com/topic/4236563

joodle

@AsadHaider i dont use php-fpm

giang

Try to create folder /var/run/www/ and set permision to www-data:www-data

Try this:D

mkdir /var/run/www/; chown -R www-data:www-data /var/run/www

Then restart php-cgi.

AsadHaider

I was right with the permissions part :P

php-cgi works fine for me, so why should i choose php-fpm?

It's far better, for one.

William

yea, and it runs as own process

I got this problem with LEA's script too :P That's why I could figure out how to fix it. This only happens on Ubuntu OS :D

I did test php-fpm and php-cgi on my VPS, php-cgi processed Wordpress faster than php-fpm a little bit (about .2s)

you must use temp folder for php socket it's better, edit php-cgi config and change this line "unix:/var/run/www/php.sock" to this:

unix:/tmp/php.sock and chown tmp directory : chown -R www-data:www-data /tmp

then restart nginx + php-cgi :)

Probably because php-fpm needs more time to spawning process / children. Try static instead of dynamic or ondemand

chown the whole tmp directory to www-data? Not a great idea...

tmp folder is 777 already?
