1. Upstream timed out (110: Connection timed out) while reading response header from upstream

这种情况主要在下面两种情况下发生:

• a. Nginx 作为 proxy，需要适当的调整 proxy timeout 的值。

location / {        ...        proxy_connect_timeout 70;        proxy_read_timeout 150;        proxy_send_timeout 150; ... }

• b. Nginx作为 php-fpm 等其他的有上游服务，需要适当的调整 fastcgi_read_timeout 选项值

location ~* .php$ {        include         fastcgi_params;        fastcgi_index   index.php;        fastcgi_read_timeout 150;        fastcgi_pass    127.0.0.1:9000;        fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;    }

2、open() “/usr/local/nginx/html/favicon.ico” failed (2: No such file or directory)

只需要关闭 favicon.ico 的 log：

location  /favicon.ico {        log_not_found off;        access_log off;    }
