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

这种情况主要在厦门两种情况下发生:

1. nginx proxy

需要适当的调整proxy_read_timeout值。

location / { ... proxy_read_timeout 150; ... }

1 2 3 4 5

location / {         ...         proxy_read_timeout 150;         ...     }

2. 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; }

1 2 3 4 5 6 7

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; }
