步驟
0：selinux,iptables
1 安裝包
2 啟服務
3 修改配置文件;reload,restart
4 測試
網卡模式不要橋接：

}
實驗：tftp服務
1 yum install tftp-server
2 systemctl start tftp.socket
3 systemctl enable tftp
實驗：實現CENTOS7 PXE安裝
0 selinux ,firewall 關閉
1 安裝包
yum install dhcp tftp-server httpd syslinux
systemctl enable dhcpd httpd tftp.socket
systemctl start httpd
2 準備YUM源
