4.1 首次登陆系统
登陆系统有这么难吗？并不难啊！虽然说是这样说，然而很多人第一次登陆 Linux的感觉都是“接下来我要干啥？”如果是以图形接口登陆的话，或许还有很多好玩的 事物， 但要是以命令行登陆的话，面对着一片黑压压的屏幕，还真不晓得要干嘛呢！ 为了让大家更了解如何正确的使用Linux， 正确的登陆与离开系统还是需要说明的！
4.1.1 首次登陆CentOS 7.x图形接口
开机就开机呀！怎么还有所谓的登陆与离开呀？不是开机就能够用计算机了吗？ 开什么玩笑，在Linux系统中由于是多用户多任务的环境，所以系统随时都有很多不同 的用户所下达的任务在进行， 因此正确的开关机可是很重要的！不正常的关机可能会 导致文件系统错乱，造成数据的毁损呢！这也是为什么通常我们的Linux主机都会加挂 一个不断电系统啰！
如果在第三章一切都顺利的将CentOS 7.x完成安装并且重新开机后， 应该就会出 现如下的等待登陆的图形画面才对。画面中1号箭头显示目前的日期与时间，2号箭头则 是辅助功能、语系、音量与关机钮， 3号箭头就是我们可以使用帐号登陆的输入框框， 至于4号箭头则是在使用特别的帐号登陆时才会用到的按钮。
