[求助] 首字节加载慢 + connect() to unix:/tmp/php-71-cgi.sock failed

d40355

hi，我的wdcp下运行了discuz程序，近期发现首字节waiting ttfb加载比较慢，有时最高能到10几秒的等待时间，上了CDN打开速度是很快，不过ttfb还在。
如何能破解首字节等待太久的问题啊……

另外

connect() to unix:/tmp/php-71-cgi.sock failed (11: Resource temporarily unavailable)
后台nginx错误日志里面这个问题
网上搜了好些方法（有的说listen = /tmp/php-71-cgi.sock改成127.0.0.1 同时他提到会导致phpmyadmin打不开），我还没敢尝试……不知道哪个适用wdcp

求赐教。跪谢
以下是我的配置%
