nginx 报错 upstream timed out (110: Connection timed out)解决方案

一、nginx 作PHP的web接口服务器，在线上发现时不时经常崩溃。504，导致接口访问无响应回复。

    查看日志：

[error] 11618#0: *324911 upstream timed out (110: Connection timed out) while reading response header from upstream, 
client:

解决方法：

[root@m2 vhosts]# cat nginx.conf
server {
    	listen 80;
        server_name zabbix.gree.com;
        access_log /roobo/logs/nginx/zabbix.gree.com_access.log main;
        error_log /roobo/logs/nginx/zabbix.gree.com_error.log error ;
    	root /roobo/webserver/zabbix;
    	index index.html index.htm index.php;

    	location / {
        	try_files $uri $uri/ /index.php$is_args$args;
    	}
    	location ~ \.php$ {
        	try_files $uri =404;
        	include fastcgi.conf;
        	fastcgi_pass 10.7.19.195:9000;
        }

       #error Connection timed out and 504 error
       large_client_header_buffers 4 16k;
       client_max_body_size 30m;
       client_body_buffer_size 128k;
       fastcgi_connect_timeout 300;
       fastcgi_read_timeout 300;
       fastcgi_send_timeout 300;
       fastcgi_buffer_size 64k;
       fastcgi_buffers   4 32k;
       fastcgi_busy_buffers_size 64k;
       fastcgi_temp_file_write_size 64k;
}

在server标签内增加k下内容

       #error Connection timed out and 504 error
       large_client_header_buffers 4 16k;
       client_max_body_size 30m;
       client_body_buffer_size 128k;
       fastcgi_connect_timeout 300;
       fastcgi_read_timeout 300;
       fastcgi_send_timeout 300;
       fastcgi_buffer_size 64k;
       fastcgi_buffers   4 32k;
       fastcgi_busy_buffers_size 64k;
       fastcgi_temp_file_write_size 64k;

再重启nginx服务。
