安装源：

git clone https://gitlab.com/gitlab-org/gitlab-ce.git -b 7-10-stable gitlab

安装文档：

在github上：gitlabhq/doc/install/installation.md

执行：sudo -u git -H bundle install --deployment --without development test mysql aws

报错信息如下：

Errno::ECONNRESET: Connection reset by peer - SSL_connect (http://rubygems.org/)

解决：修改gem source

修改运行目录中的Gemfile文件的第一行：

source "https://ruby.taobao.org/"

重新安装ruby，执行遇到以下问题：

ERROR:  Error installing bluecloth:

ERROR: Failed to build gem native extension.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby

extconf.rb

mkmf.rb can't find header files for ruby at

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h

可以通过安装ruby-devel来解决。但是在ubuntu系统下要用以下命令：

apt-get install ruby-full

然后又出现以下错误：

git@test1host:~/gitlab$ bundle install --deployment --without development test mysql aws
Fetching source index from https://ruby.taobao.org/
Using rake 10.4.2

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.

解决：更新gcc，更换ubuntu官方源，apt-get重新安装gcc并安装g++。
