RHEL7(Centos7)下使用shell脚本一键部署服务(三)
更新内容:增加了一键部署PXE+kickstart无人值守安装服务，经测试，无任何问题。欢迎大家测试和提出意见，写作不易，还望支持。
目前可以完成的功能
1、一键配置yum源
2、配置IP地址
3、搭建NFS服务
4、搭建DHCP服务
5、搭建DNS服务
6、一键部署PXE+kickstart无人值守安装服务

与centos7系统几乎通用(只需修改几处小地方)
一键部署PXE+kickstart无人值守安装服务运行结果如下：
重新创建一台虚拟机，测试是否可用。
记得网卡模式调成仅主机模式
出现这个页面之后只需要就证明已经成功了，只需喝杯茶，等待一会，系统就安装成功了。
