ip a 查看网卡名称

运行脚本：bash /init_ip.sh

网卡名称填写自己的，一般是ens33/ens160/eth0

ip地址：172.25.254.40

4.一定要关闭VMware dhcp功能

5.挂载镜像 mount /dev/sr0 /mnt

6.配置仓库方便下载

vim /etc/yum.repos.d/npm.repo

3.图形化生成kickstart自动安装脚本

3.1 下载kickstart工具

yum install system-config-kickstart

3.2 启动kickstart图形制作工具

system-config-kickstart

3.3 生成ks.cfg自动安装脚本

3.4 查看生成的ks.cfg文件

vim ks.cfg

检查ks.cfg是否有语法错误

ksvalidator ks.cfg

4.配置httpd，在浏览器中可以访问/mnt和ks.cfg目录

4.1 下载httpd

yum install httpd -y

4.2 编写/etc/httpd/conf.d/vhost.conf

vim /etc/httpd/conf.d/vhost.conf

 	allowoverride none 	require all granted    	servername 172.25.254.40 	documentroot /var/www/html 

 4.3 将需要共享的目录文件放到/var/www/html

返回到家目录

cd

复制ks.cfg

cp ks.cfg /var/www/html

创建镜像挂载目录的软链接到/var/www/html下

ln -s /mnt /var/www/html/mnt

4.4 重启httpd和关闭防火墙

systemctl restart httpd

systemctl stop firewall

setenforce 0

4.5访问172.25.254.40/ks.cfg和172.25.254.40/mnt

5.配置DHCP服务

5.1 下载dhcp服务

yum install dhcp -y

5.2 编写dhcp配置文件

编写时可以借助模版/usr/share/doc/dhcp*/dhcpd.conf.example

直接拷贝一份模版文件

\cp  -f   /usr/share/doc/dhcp*/dhcpd.conf.example   /etc/dhcp/dhcpd.conf

vim  /etc/dhcp/dhcpd.conf

# dhcpd.conf # # Sample configuration file for ISC dhcpd #  # option definitions common to all supported networks...  #公司域名，自己取的 option domain-name "caikeyou.org"; #对外分发的dns地址 option domain-name-servers 114.114.114.114;  default-lease-time 600; max-lease-time 7200;  # Use this to enble / disable dynamic dns updates globally. #ddns-update-style none;  # If this DHCP server is the official DHCP server for the local # network, the authoritative directive should be uncommented. #authoritative;  # Use this to send dhcp log messages to a different log file (you also # have to hack syslog.conf to complete the redirection). log-facility local7;  # No service will be given on this subnet, but declaring it helps the  # DHCP server to understand the network topology.  #subnet 10.152.187.0 netmask 255.255.255.0 { #}  # This is a very basic subnet declaration.  #IP网段和子网掩码 subnet 172.25.254.0 netmask 255.255.255.0 {   #dhcp地址池，分发地址的范围   range 172.25.254.80 172.25.254.90;   #网关   option routers 172.25.254.2;   #正常配置dhcp服务不用写，但是我们希望将下面的目录一起发送给请求主机，实现服务器的自动化部署   next-server 172.25.254.40;   filename "pxelinux.0"; } 

重启dhcp服务

systemctl enable --now dhcpd

6.搭建pxe网络安装环境实现服务器自动部署

6.1 下载环境

yum install syslinux.x86_64

共享pxelinux.0数据文件的网络服务

查看下载安装包

rpm -ql tftp-server

设置开机自启动

systemctl enable --now tftp

6.2 拷贝文件目录

复制挂载镜像目录/mnt下的isolinux

cp  /mnt/isolinux/*   /var/lib/tftpboot/

cp  /usr/share/syslinux/pxelinux.0  /var/lib/tftpboot/

cd   /var/lib/tftpboot/

mkdir   pxelinux.cfg

cp ioslinux.cfg   pxelinux.cfg/default

6.3 编辑/var/lib/tftpboot/pxelinux.cfg/default文件

vim pxelinux.cfg/default 

7.新建一台rhel7

按上下键选择项，然后按+-实现上下挪动，使顺序与下面一样
