Obrigado pela ajuda, laurent!
Acabei deixando essa configuração no nginx:
upstream gitlab {
server unix:/home/gitlab/gitlab/tmp/sockets/gitlab.socket;
}
server {
listen 80 default; # e.g., listen 192.168.1.1:80;
#server_name thinkstation-ubuntu; # e.g., server_name source.example.com;
root /home/gitlab/gitlab/public;
# individual nginx logs for this gitlab vhost
access_log /var/log/nginx/gitlab_access.log;
error_log /var/log/nginx/gitlab_error.log;
location / {
# serve static files from defined root folder;.
# @gitlab is a named location for the upstream fallback, see below
try_files $uri $uri/index.html $uri.html @gitlab;
}
# if a file, which is not found in the root folder is requested,
# then the proxy pass the request to the upsteam (gitlab unicorn)
location @gitlab {
proxy_read_timeout 300; # https://github.com/gitlabhq/gitlabhq/issues/694
proxy_connect_timeout 300; # https://github.com/gitlabhq/gitlabhq/issues/694
proxy_redirect off;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://gitlab;
}
}
E isso funciona! A configuração final é:
Host do Windows7: Interface somente de host criada, ip 192.168.56.1, encaminhamento de porta configurado: host 8888 para guest 80
Convidado do servidor Ubuntu 12.04: executando nginx, eth0 como NAT do VirtualBox, eth1 com somente host, com ip estático 192.168.56.101
Ubuntu 12.04 Desktop: eth0 como Virtualbox NAT, eth1 com Host-only com ip estático 192.168.56.102, acessando diretamente 192.168.56.101 nginx, ssh, todos os serviços.
Obrigado!
