Erro 502 Bad Gateway help

[四弦]

Hello,
Where did you PHP install?
You can edit /path/to/php_dir/etc/php-fpm.conf,or sometimes there will be a
dir called 'www.conf.d',if it is,please change in the directory,and edit
www.conf which is in the www.conf.d.
You will find a option called 'listen' in the configuration file below,make
sure the option's content is '127.0.0.1:8080',if not,you can edit it as
'127.0.0.1:8080'.You can also edit the nginx configuration file,change the
option 'fastcgi_pass'.
But I recommend use socket to connect php-fastcgi,it is faster.To do
this,just change the php-fpm.conf or www.conf likes follow:
[www]
...
user=www
group=www
...
listen = /dev/shm/php-cgi.sock
listen.owner = www
listen.group = www
listen.mode = 0660



'...'just stands for something omitted.
And then change the 'fastcgi_pass' option to
'unix:/dev/shm/php-cgi.sock',restart nginx and PHP,all done!

P.S:My mother tongue isn't English,if there is something you couldn't
understand,please let my konw,thanks!
