我正在尝试设置Nginx,Unicorn和Rails应用程序以一起工作.
Nginx和Nnicorn正在运行,我使用ps命令进行了检查.
但是当我尝试访问我的页面时,我却遇到了502 Bad Gateway
Nginx错误日志包含以下行:
2015/03/18 19:53:26 [error] 14319#0: *1 connect() to
unix:/var/sockets/unicorn.mypage.sock failed (11: Resource temporarily
unavailable) while connecting to upstream
可能是什么问题?
我的/etc/nginx/conf.d/default.conf
upstream app {
server unix:/var/sockets/unicorn.mypage.sock fail_timeout=0;
}
server {
listen 80;
server_name mypage.com;
# Application root,as defined previously
root /home/rails/mypage/public;
location ^~ /assets/ {

location @app {

working_directory "/home/rails/mypage"

stdout_path "/home/rails/mypage/log/unicorn.log"

最佳答案
它看起来像套接字问题,但是套接字关闭时通常是(111:连接被拒绝),所以我认为这是应用程序问题(高负载,执行缓慢等).
尝试减少积压,然后再次查看日志以获取详细信息:
listen "/var/sockets/unicorn.mypage.sock",backlog: 64
:backlog => number of clients
