I am trying to setup a server where my git repo would be accessible with HTTP(S).

I am using gitolite and nginx (and gitlab for web interface but I doubt it makes any difference).

I have searched the whole afternoon and I think I'm stuck.

I have think I have understood that nginx needs fcgiwrap to work with gitolite, so I tried several configurations, but none of them work.

My repositories are at /home/git/repositories.

Here's the three nginx configurations I have tried.

1:

   location ~ /git(/.*) {
       gzip off;
       root /usr/lib/git-core;

       fastcgi_pass  unix:/var/run/fcgiwrap.socket;
       include /etc/nginx/fcgiwrap.conf;

       fastcgi_param SCRIPT_FILENAME /usr/lib/git-core/git-http-backend;
       fastcgi_param DOCUMENT_ROOT /usr/lib/git-core/;
       fastcgi_param SCRIPT_NAME git-http-backend;

       fastcgi_param GIT_HTTP_EXPORT_ALL "";
       fastcgi_param GIT_PROJECT_ROOT /home/git/repositories;
       fastcgi_param PATH_INFO $1;
       #fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
    }

Result:

> git clone http://myservername/projectname.git test/
Cloning into test...
fatal: http://myservername/projectname.git/info/refs not found: did you run git update-server-info on the server?

and

> git clone http://myservername/git/projectname.git test/
Cloning into test...
error: The requested URL returned error: 502 while accessing http://myservername/git/projectname.git/info/refs
fatal: HTTP request failed

2:

   location ~ /git(/.*) {
        fastcgi_pass  localhost:9001;
        include       /etc/nginx/fcgiwrap.conf;
        fastcgi_param SCRIPT_FILENAME     /usr/lib/git-core/git-http-backend;
        fastcgi_param GIT_HTTP_EXPORT_ALL "";
        fastcgi_param GIT_PROJECT_ROOT    /home/git/repositories;
        fastcgi_param PATH_INFO           $1;
    }

Result:

> git clone http://myservername/projectname.git test/
Cloning into test...
fatal: http://myservername/projectname.git/info/refs not found: did you run git update-server-info on the server?

and

> git clone http://myservername/git/projectname.git test/
Cloning into test...
error: The requested URL returned error: 502 while accessing http://myservername/git/projectname.git/info/refs
fatal: HTTP request failed

3:

location ~ ^.*\.git/objects/([0-9a-f]+/[0-9a-f]+|pack/pack-[0-9a-f]+.(pack|idx))$ {
    root /home/git/repositories/;
  }

  location ~ ^.*\.git/(HEAD|info/refs|objects/info/.*|git-(upload|receive)-pack)$ {
    root /home/git/repositories;

    fastcgi_pass unix:/var/run/fcgiwrap.socket;
    fastcgi_param SCRIPT_FILENAME   /usr/lib/git-core/git-http-backend;
    fastcgi_param PATH_INFO         $uri;
    fastcgi_param GIT_PROJECT_ROOT  /home/git/repositories;  
    include /etc/nginx/fcgiwrap.conf;
  }

Result:

> git clone http://myservername/projectname.git test/
Cloning into test...
error: The requested URL returned error: 502 while accessing http://myservername/projectname.git/info/refs
fatal: HTTP request failed

and

> git clone http://myservername/git/projectname.git test/
Cloning into test...
error: The requested URL returned error: 502 while accessing http://myservername/git/projectname.git/info/refs
fatal: HTTP request failed

Also note that with any of those configurations, when I try to clone with a project name that actually doesn't exist, I get a 502 error.

Does anyone already succeeded in doing this? What am I doing wrong?

Thanks.

UPDATE:

nginx error log file said:

2012/04/05 17:34:50 [crit] 21335#0: *50 connect() to unix:/var/run/fcgiwrap.socket failed (13: Permission denied) while connecting to upstream, client: 192.168.12.201, server: myservername, request: "GET /git/oct_editor.git/info/refs HTTP/1.1", upstream: "fastcgi://unix:/var/run/fcgiwrap.socket:", host: "myservername"

So I changed permissions for /var/run/fcgiwrap.socket, and now I have :

> git clone http://myservername/git/projectname.git test/
Cloning into test...
error: The requested URL returned error: 403 while accessing     http://myservername/git/projectname.git/info/refs
fatal: HTTP request failed

Here is the error.log file I have now:

2012/04/05 17:36:52 [error] 21335#0: *78 FastCGI sent in stderr: "Cannot chdir to script directory (/usr/lib/git-core/git/projectname.git/info)" while reading response header from upstream, client: 192.168.12.201, server: myservername, request: "GET /git/projectname.git/info/refs HTTP/1.1", upstream: "fastcgi://unix:/var/run/fcgiwrap.socket:", host: "myservername"

I keep on investigating.
