1：系统和软件：
root@ubuntu1:/home/ubuntu1# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.3 LTS
Release: 14.04
Codename: trusty2：下载gitlab安装包：
https://about.gitlab.com/downloads/archives/注：下载相应的系统对应的版本。
3：安装需要的openssh和mail服务：
sudo apt-get install openssh-server
sudo apt-get install postfix 注：邮件选择：No configuration！之后自己配置！
4：安装“gitlab-ce_7.10.4~omnibus-1_amd64.deb”，[内含Ruby、Redis，Nginx和PostgreSQL]：
sudo dpkg -i gitlab-ce_7.10.4~omnibus-1_amd64.deb5：配置访问域名端口和邮箱：
sudo vim /etc/gitlab/gitlab.rb
#unicorn端口冲突--配置9090，默认8080！
unicorn['port'] = 9090
#配置gitlab的域名或ip和端口
external_url 'http://192.168.1.110:8080'
#配置邮件
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "eg.smtp.163.com"
gitlab_rails['smtp_port'] =25
gitlab_rails['smtp_user_name'] = "your email"
gitlab_rails['smtp_password'] = "your passwd"
gitlab_rails['smtp_domain'] = "eg.smtp.163.com"
gitlab_rails['smtp_authentication'] = :login
gitlab_rails['smtp_enable_starttls_auto'] = true
#163邮箱，修改gitlab配置的发信人
gitlab_rails['gitlab_email_from'] = "your email"
user["git_user_email"] = "your email"
注：若nginx有权限问题问题则将nginx.conf中启动用户修改成root.
6：GitLab进行重加载gitlab.rb配置启动：
sudo gitlab-ctl reconfigure7：检测GitLab状态：
sudo gitlab-ctl status
run: logrotate: (pid 16722) 2161s; run: log: (pid 3316) 45362s
run: nginx: (pid 3297) 45364s; run: log: (pid 3296) 45364s
run: postgresql: (pid 3180) 45383s; run: log: (pid 3179) 45383s
run: redis: (pid 3081) 45389s; run: log: (pid 3080) 45389s
run: sidekiq: (pid 3272) 45370s; run: log: (pid 3271) 45370s
run: unicorn: (pid 3244) 45372s; run: log: (pid 3243) 45372s注：若状态都为down，则使用，启动：
sudo gitlab-ctl start
ok: run: logrotate: (pid 14246) 1s
ok: run: nginx: (pid 14249) 0s
ok: run: postgresql: (pid 14257) 0s
ok: run: redis: (pid 14265) 1s
ok: run: sidekiq: (pid 14269) 0s
ok: run: unicorn: (pid 14273) 1s8：检查GitLab的日志：
sudo gitlab-ctl tail9：请求git的web版：http://192.168.1.110:8080/
由于GitLab包自带了Ruby、Redis，Nginx和PostgreSQL，所以也就不需要考虑太多兼容性的问题。
直接Web登录GitLab所在的服务器，并使用帐号root，密码5iveL!fe来登录GitLab{此密码为默认}。
首次登录GitLab会强行让你重置密码，然后就可以进入GitLab了。
10:停止服务
sudo gitlab-ctl stop
ok: down: logrotate: 0s, normally up
ok: down: nginx: 1s, normally up
ok: down: postgresql: 0s, normally up
ok: down: redis: 1s, normally up
ok: down: sidekiq: 0s, normally up
ok: down: unicorn: 1s, normally up问题1：注：错误码对应解释网易服务器smtp机器要求身份验证帐号和发信帐号必须一致，如果用户在发送邮件时，身份验证帐号和发件人帐号是不同的，因此拒绝发送。修改gitlab.rb，修改发信人和身份验证帐号一致，163发信OK。
问题2：Nginx默认监听80端口，unicorn默认监听8080端口，如使用此两个端口请修改配置！

gitlab: Thank you for installing GitLab!
gitlab: Configure and start GitLab by running the following command:
gitlab:
gitlab: sudo gitlab-ctl reconfigure
gitlab:
gitlab: GitLab should be reachable at http://dubbo
gitlab: Otherwise configure GitLab for your system by editing /etc/gitlab/gitlab.rb file
gitlab: And running reconfigure again.
