(1)nginx+php

nginx+php-fpm打开速度如果很慢的话要检查下nginx的错误日志，我就发现“an upstream response is buffered to a temporary file /var/cache/nginx/fastcgi_temp/3/26/0000014263 while reading upstream”很多这样的错误，原来是因为fascgi缓存设置太小导致的，参照网上的方案修改：nginx配置：

fastcgi_buffers 32 8k;


client_max_body_size 500m;

client_body_buffer_size 1024k;

问题解决。参考：http://rickie622.blog.163.com/blog/static/2123881120116185123407/
