Help with Nginx reverse proxy

thatix

Hi, all

Since wikipedia is inaccessible from my country, I am wondering if it is possible to reverse proxy it for private use. However, I am bumping into a 500 internal server error.

I am using

w.domain.tld for zh.wikipedia.org

m.w.domain.tld for zh.m.wikipedia.org

up.w.domain.tld for upload.wikimedia.org

Here is my nginx config

    server {
listen 80;
    server_name w.domain.tld ;
    return 301 https://$host$request_uri;
    }
     server {
server_name w.domain.tld;
listen 443;
    ............. #my ssl config
    location / {
proxy_pass https://zh.wikipedia.org;
    proxy_cookie_domain zh.wikipedia.org w.domain.tld;
    proxy_redirect https://zh.wikipedia.org/ /;
    proxy_redirect https://zh.m.wikipedia.org/ https://m.w.domain.tld/;
    proxy_set_header X-Real_IP $remote_addr;
    proxy_set_header User-Agent $http_user_agent;
    proxy_set_header Accept-Encoding ''; 
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
proxy_set_header X-Forwarded-Proto https;
proxy_set_header Host "zh.wikipedia.org";
proxy_set_header Referer "https://zh.wikipedia.org$request_uri";
    subs_filter_types text/css text/xml text/javascript;
subs_filter zh.wikipedia.org w.domain.tld;
    subs_filter upload.wikimedia.org up.w.domain.tld;
    subs_filter zh.m.wikipedia.org m.w.domain.tld;
sub_filter_once off; 
    }

The config of server block for other two domains corresponding to zh.m.wikipedia.org and upload.wikimedia.org are pretty similar.
No matter what it always shows a 500 error(while nothing appeared in error.log),at the same time ,another similar copy of the config works fine with google.
(I have been tring to sort it out for serveral days and still no clue)

Running nginx 1.2.1 with nginx_substitutions_filter module (which replace my domain instead of wikipedia's domain on any files )

Any thoughts or ideas really appreciated

Kindly

Though reverse proxying is more convenient, since you can transparently use it on all your devices, it can break if the website structure changes etc.

I would recommend you to setup SSH tunnel with SOCKS proxy to some VPS. Then you can have one browser for a regular use, and another browser for restricted websites using your SOCKS proxy.

Is it possible to forward all https links/connections/requests into http on nginx? I have a chat script that stop working when on https maybe because there are links/content in the script on http so they are blocked when accessing on http and chat stop loading.

That's exactly why I want to set this up, under particular circumstances, it would be very inconvenient to use a forward proxy(i.e. someone else's computer or a computer at school)

The strange thing is that a similar configuration works for Google.

Still have no idea on this

Alright guys, I have finally fixed this sh*t.

proxy_cookie_domain should be wikipedia.org instead of zh.wikipedia.org otherwise you will get a 500 error.

Once cookie domain is corrected , a wikipedia mirror site is up

Works pretty fine on a 128MB box thanks to @tragic
