php 解决：502 bad gateway

写好上线没什么想法，活动开始，网站慢慢被更多人知道，访问的越来越多，每天最高16W的访问量，突然投诉多了，说：502 bad gateway

搞了一天多时间，最后终于试出来了：网上有关502的解决方法太多了，我都去试了，帖子抄袭太多，看了很多很多，试了很多很多

最后就找到一篇帖子解决了，我这种情况的问题：http://www.digitalwhores.net/ubuntu-2/error-502-connect-to-unixvarrunphp5-fpm-sock-failed-11-resource-temporarily-unavailable-while-connecting-to-upstream/   当然它的端口和我的端口值不一样

ERROR 502 – connect() to unix:/var/run/php5-fpm.sock failed (11: Resource temporarily unavailable) while connecting to upstream

Once again, i’m struggling with nginx + php-fpm

sudo nano /etc/php5/fpm/pool.d/www.conf

search for

listen = /var/run/php5-fpm.sock

and replace it for

listen = 127.0.0.1:7777

On the *.conf files of sites-enabled (/etc/nginx/sites-enabled/)
replace (or comment)

fastcgi_pass unix:/var/run/php5-fpm.sock;

with

fastcgi_pass 127.0.0.1:7777;
