实现的目的是：批量安装centos 7操作系统

详细操作

第一部分在kickstart服务上操作

1、关闭selinux

[root@localhost ~]# vim /etc/selinux/config

SELINUX=disabled //修改为disabled
#SELINUXTYPE=targeted //注释掉

2、配置防火墙允许：TCP 80 端口和 UDP 69 端口或者关闭防火墙

[root@localhost ~]# yum -y install firewalld //centos 7一般上面都没有安装包，它是用来启动防火墙服务的，类似于service iptables start

[root@localhost html]# firewall-cmd --zone=public --add-port=80/tcp --permanent //httpd服务需要此端口
[root@localhost html]# firewall-cmd --zone=public --add-port=69/udp --permanent //tftp服务需要此端口

参数详解：

--zone 作用域

--add-port=80/tcp 添加端口，格式为：端口/ 通讯协议

--permanent 永久生效，没有此参数，重启失效

[root@localhost ~]# systemctl start firewalld //启动防火墙服务

3、安装httpd服务

[root@localhost ~]# yum -y install httpd //安装httpd服务

[root@localhost ~]# systemctl start httpd //启动httpd服务

[root@localhost ~]# systemctl enable httpd //将httpd服务加入开机自动启动

4、挂在系统安装镜像到httpd服务器站点根目录

[root@localhost ~]# mkdir /var/www/html/os/ //创建挂载目录
[root@localhost ~]# mount /dev/cdrom /var/www/html/os/ //挂载系统镜像

5、安装tftp服务

[root@localhost ~]# yum -y install tftp tftp-server xinetd//安装

[root@localhost ~]# vim /etc/xinetd.d/tftp //编辑

disable = no //修改

[root@localhost ~]# systemctl start xinetd //启动

[root@localhost ~]# systemctl enable xinetd //将xinetd服务加入开机自动启动

[root@localhost ~]# cp /var/www/html/os/images/pxeboot/vmlinuz /var/lib/tftpboot/
[root@localhost ~]# cp /var/www/html/os/images/pxeboot/initrd.img /var/lib/tftpboot/
[root@localhost ~]# mkdir -p /var/lib/tftpboot/pxelinux.cfg
[root@localhost ~]# cp /var/www/html/os/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
[root@localhost ~]# vim /var/lib/tftpboot/pxelinux.cfg/default

[root@localhost ~]# chmod -R 644 /var/lib/tftpboot/pxelinux.cfg/default //设置文件文件权限
[root@localhost ~]# yum -y install syslinux //安装引导程序

[root@localhost ~]# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/ //拷贝引导文件到tftp服务根目录下

6、[root@localhost ~]# yum -y install dhcp //安装dhcp服务

ddns-update-style interim; //设置DHCP服务器模式

subnet 172.16.1.0 netmask 255.255.255.0 { //配置网段
range 172.16.1.100 172.16.1.200; //配置dhcp服务器的租用地址范围
option domain-name-servers 222.222.222.222; //配置dns
option domain-name "internal.example.org";
option routers 172.16.1.254; // 配置网关
option broadcast-address 10.5.5.31;
default-lease-time 600; //默认租约时间
max-lease-time 7200; //最大租约时间
next-server 172.16.1.90; // tftp服务器地址
filename "pxelinux.0"; //tftp服务器根目录下的文件名

[root@localhost ~]# vim /etc/sysconfig/dhcpd //

DHCPDARGS=ens33 //设置dhcp服务器模式

[root@localhost ~]# dhcpd //测试dhcp服务配置是否正确
[root@localhost ~]# systemctl start dhcpd //启动dhcpd服务
[root@localhost ~]# systemctl enable dhcpd //
7、配置kickstart自动安装文件

注意：在安装kickstart之前先编辑下面的文件，亲一定要写否则会报错例如：下面的这个图
