Nginx Upstream timed out (110: Connection timed out)

在Nginx错误日志中,有大量的下列信息:

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

发生有两种情形:

  1. nginx proxy

需要适当的调整proxy_read_timeout值。

location / {
        ...
        proxy_read_timeout 150;
        ...
    }
  1. Nginx作为php-fpm等等其他的有上游服务

在这种情况下,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;
}
