Nginx 错误汇总

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 300;
        proxy_read_timeout 300;
        proxy_send_timeout 300;
        ...
    }

• 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;
    }
