我将Puma作为上游应用服务器运行,Riak作为后台数据库集群运行。当我发送一个请求,映射减少了大约25K用户的数据块,并从Riak返回到应用程序,我在Nginx日志中得到一个错误:
upstream timed out (110: Connection timeout) while reading 来自upstream的响应头
如果我直接查询我的上游没有nginx代理,同样的请求,我得到所需的数据。
一旦代理被放入Nginx超时就会发生。
**nginx.conf**
http {
keepalive_timeout 10m;
proxy_connect_timeout 600s;
proxy_send_timeout 600s;
proxy_read_timeout 600s;
fastcgi_send_timeout 600s;
fastcgi_read_timeout 600s;
include /etc/nginx/sites-enabled/*.conf;
}
**virtual host conf**
upstream ss_api {
server 127.0.0.1:3000 max_fails=0 fail_timeout=600;
}
server {
listen 81;
server_name xxxxx.com; # change to match your URL
location / {
# match the name of upstream directive which is defined above
proxy_pass http://ss_api;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_cache cloud;
proxy_cache_valid 200 302 60m;
proxy_cache_valid 404 1m;
proxy_cache_bypass $http_authorization;
proxy_cache_bypass http://ss_api/account/;
add_header X-Cache-Status $upstream_cache_status;
}
}
Nginx有一堆超时指令。我不知道我是不是错过了什么重要的东西。任何帮助将高度赞赏....
