问题
Similar to this, I am trying to host a squid proxy behind nginx:
example.com
- the main site
relay.example.com
- the squid server.
So far, when I try to use the squid proxy, it will complain about accessing an illegal page, for example, if I try to access http://www.google.com
, I get an Invalid URL error saying that the URL /http://www.google.com
(note the preceding /). Could anyone suggest why this is happening, or a fix for nginx or perhaps in the squid config?
upstream @squid {
server localhost:3128;
}
server {
listen 80;
server_name relay.example.com;
location / {
proxy_pass http://@squid/$scheme://$host$uri;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Request-URI $request_uri;
proxy_redirect off;
}
}

The log from squid gives:
1423083723.857 0 127.0.0.1 NONE/400 3530 GET /http://www.google.com/ - HIER_NONE/- text/html
And nginx for the same request:
12.34.56.78 - - [04/Feb/2015:16:02:03 -0500] "GET http://www.google.com/ HTTP/1.1" 400 3183 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:35.0) Gecko/20100101 Firefox/35.0" "-"
回答1:
in nginx:
proxy_pass http://@squid;
in squid:
http_port 3128 vhost
and that's all you need for fix this https://imgur.com/qtgrZI9 error

I had this same problem, solved it by setting squid to run in transparent mode, like this:
http_port 3128 transparent
