现在就迫不及待的来开始我们自己的GitLab服务器的搭建吧。由于我们是个人用户的探索，所有我们选择免费的GitLab Community Edition进行演示；
1.首先，我们应当明确GitLab只支持Unix的发布版（故，我在Mac虚拟机中安装Ubuntn）：
2.其次，对硬件的要求如CPU（建议双核）、内存（建议2G）、存储、数据库和阅读器等，由于目前的电脑配置基本都满足，并且我们只是进行搭建服务器的演示操作，所以没必要要过量的纠结；如果在实际的开发的场景中，请参考官方文档：https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/install/requirements.md；
安装进程中，提示配置General type of mail configuration选择Internet Site，提示配置System mail name输入xxx.com便可：

5.配置和启动GitLab 第1启动的时候，会履行如安装依赖包，初始化数据库等等操作；

6.阅读主机和登录 接下来我们在阅读器中输入localhost，就能够访问GitLab服务了，以下图：
第1次访问的时候，你将会跳转到密码重置页面来初始化管理员账户密码。输入你的密码后你将会被跳转到登录页面，默许的账户名称root。登录完成以后，你可以根据你的意愿修改用户名。
