nginx connect() to unix:/var/run/php-fpm.sock failed (11: Resource temporarily unavailable)_nginx

网站常出现502 bad gateway，程序没有问题。

根据nginx日志：

复制代码 代码如下:

connect() to unix:/var/run/php-fpm.sock failed (11: Resource temporarily unavailable)

发现phpfpm的listen是unix sock方式运行的，问题可能出在php fpm上。php fpm配置文件里有backlog，backlog是linux服务器在socket处理连接数的定义，phpfpm默认为-1，将-1改为4096，重启php fpm问题解决。
