Answer 1

你如果用的是mysql，就不需要安装postgresql的东西。

# For MySQL (note, the option says "without ... postgres")
sudo -u git -H bundle install --deployment --without development test postgres aws

https://github.com/gitlabhq/gitlabhq/blob/master/doc/install/installation.md

upstream gitlab {
  server unix:/home/git/gitlab/tmp/sockets/gitlab.socket;
}

server {
  listen 10.10.11.111:80 default_server;         # e.g., listen 192.168.1.1:80; In most cases *:80 is a good idea
  server_name 'git.abc.com';     # e.g., server_name source.example.com;
  server_tokens off;     # don't show the version number, a security best practice
  root /home/git/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_pass http://gitlab;

打开你的Gemfile文件，添加

gem 'pg'

然后

bundle install
