Hello,
I followed your tutorial here
the problem is when I try to access my site vma.example.com it’s always shows 502 bad gateway error. Here’s the error log:
2014/04/04 04:11:09 [error] 6926#0: *5 connect() failed (111: Connection refused) while connecting to upstream, client: 121.54.44.134, server: vma.example.com, request: “GET / HTTP/1.1”, upstream: “fastcgi://127.0.0.1:9000”, host: “vma.example.com”
