Howto Nginx + git-http-backend + fcgiwrap (Debian Squeeze)
- by brainsqueezer
I am trying to setup git-http-backend with Nginx but after 24 hours wasting time and reading everything I could I think this config should work but doesn't.
server {
listen 80;
server_name mydevserver;
access_log /var/log/nginx/dev.access.log;
error_log /var/log/nginx/dev.error.log;
location / {
root /var/repos;
}
location ~ /git(/.*) {
gzip off;
root /usr/lib/git-core;
fastcgi_pass unix:/var/run/fcgiwrap.socket;
include /etc/nginx/fastcgi_params2;
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 /var/repos;
fastcgi_param PATH_INFO $1;
#fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
}
}
Content of /etc/nginx/fastcgi_params2
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
fastcgi_param REMOTE_USER $remote_user;
# required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
but config seems not working
$ git clone http://mydevserver/git/myprojectname/
Cloning into myprojectname...
warning: remote HEAD refers to nonexistent ref, unable to checkout.
and I can request an unexistant project and I will get the same answer
$ git clone http://mydevserver/git/thisprojectdoesntexist/
Cloning into thisprojectdoesntexist...
warning: remote HEAD refers to nonexistent ref, unable to checkout.
If I change root to /usr/lib I will get a 403 error and this will be reported to nginx error log:
2011/11/23 15:52:46 [error] 5224#0: *55 FastCGI sent in stderr: "Cannot get script
name, is DOCUMENT_ROOT and SCRIPT_NAME set and is the script executable?" while
reading response header from upstream, client: 198.168.0.4, server: mydevserver,
request: "GET /git/myprojectname/info/refs HTTP/1.1", upstream:
"fastcgi://unix:/var/run/fcgiwrap.socket:", host: "mydevserver"
My main trouble is with the correct root value with this configuration. Maybe there are some permissions problems.
Notes:
/var/repos/ is owned by www-data and contains folders bit git bare repos.
All this works perfectly using ssh.
If I go with my browser to http://mydevserver/git/myproject/info/refs it is answered by git-http-backend asking me to send a command.
/var/run/fcgiwrap.socket has 777 permissions.
