我将nginx更新到1.4.7，将php更新到5.5.12，之后我得到了502错误。在我更新之前，一切都很好。
nginx-error.log
2014/05/03 13:27:41 [crit] 4202#0: *1 connect() to unix:/var/run/php5-fpm.sock failed (13: Permission denied) while connecting to upstream, client: xx.xxx.xx.xx, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "xx.xx.xx.xx"
nginx.conf
user www www;
worker_processes 1;
location / {

index index.php index.html index.htm;

location ~ [^/]\.php(/|$) {

fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/home/user/public_html$fastcgi_script_name;
include fastcgi_params;
}
查看/etc/php5/php-fpm.conf即可
Pid = /var/run/php5-fpm.pid IS pid文件
在/etc/php5/fpm/pool.d/www.conf文件中
监听= /var/run/php5-fpm.SOCKET文件
如果你pid等于监听(pid = /var/run/php5-fpm. .Sock和listen = /var/run/php5-fpm.sock) ->错误设置
设置/etc/php5/fpm/pool.d/www.conf
user = nginx
group = nginx
listen.owner = nginx
listen.group = nginx
listen.mode = 0660
如果你已经尝试了这篇文章中的所有内容，但都没有成功地让PHP工作，这是为我的案例修复的:
确保在/etc/php5/fpm/pool.d/www.conf中没有注释这些行:
listen.owner = www-data
listen.group = www-data
listen.mode = 0660
确保/etc/nginx/fastcgi_params看起来像这样:
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param PATH_INFO $fastcgi_script_name;
fastcgi_param HTTPS $https if_not_empty;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
这两行在我的/etc/nginx/fastcgi_params中丢失了，请确保它们在那里!
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_script_name;
然后重新启动php5-fpm和nginx。应该能行。
