PXE+KICKSTART部署過程基於centos7

部署過程基於centos7

環境準備

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
[root@localhost ~]# getenforce

準備安裝源

安裝DHCP服務

[root@localhost ~]# yum install dhcp ntpdate syslinux -y 
[root@localhost ~]# timedatectl set-timezone Asia/Shanghai
[root@localhost ~]# ntpdate time.windows.com
[root@localhost ~]# cp /etc/dhcp/dhcpd.conf /etc/dhcp/dhcpd.conf.bak_$(date +%Y-%m-%d-%H-%M)
[root@localhost ~]# vim /etc/dhcp/dhcpd.conf
default-lease-time 600;
max-lease-time 7200;
log-facility local7;
subnet 192.168.217.0 netmask 255.255.255.0 {
  range 192.168.217.10 192.168.217.100;
  option domain-name-servers 114.114.114.114;
  option routers 192.168.217.155;
  next-server 192.168.217.155;
  filename "pxelinux.0";
}
[root@localhost ~]# systemctl start dhcpd.service
[root@localhost ~]# systemctl enable dhcpd.service

安裝ftp

[root@localhost ~]# yum install -y vsftpd
[root@localhost ~]# mount /dev/cdrom /mnt
[root@localhost ~]# cp -rf /mnt/* /var/ftp/pub/
[root@localhost ~]# systemctl start vsftpd
[root@localhost ~]# systemctl enable vsftpd 

tftp安裝

[root@localhost ~]# yum install -y tftp-server tftp syslinux-tftpboot
[root@localhost ~]# cp /etc/xinetd.d/tftp /etc/xinetd.d/tftp.bak_$(date +%Y-%m-%d-%H-%M)
 [root@localhost ~]# vim /etc/xinetd.d/tftp
 
service tftp
{
socket_type = dgram
protocol    = udp
wait    = yes
user    = root
server  = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable = no #此處將yes該爲no
per_source  = 11
cps = 100 2
flags   = IPv4
}

配置tftp-server

[root@localhost ~]# cp -rf /usr/share/syslinux/* /var/lib/tftpboot
 
[root@localhost ~]# mkdir /var/lib/tftpboot/pxelinux.cfg
[root@localhost ~]# mkdir /var/lib/tftpboot/centos7
[root@localhost ~]# cp /mnt/images/pxeboot/vmlinuz /var/lib/tftpboot/centos7
[root@localhost ~]# cp /mnt/images/pxeboot/initrd.img /var/lib/tftpboot/centos7
[root@localhost ~]# touch /var/lib/tftpboot/pxelinux.cfg/default
[root@localhost ~]# chmod 755 /var/lib/tftpboot/pxelinux.cfg/default
 
 
[root@localhost ~]# vim /var/lib/tftpboot/pxelinux.cfg/default

適當的給權限，

[root@localhost ~]# chmod 777 /var/ftp/pub/ks.cfg 

啓動相應服務

[root@localhost ~]# systemctl restart tftp
[root@localhost ~]# systemctl restart vsftpd
[root@localhost ~]# systemctl restart dhcpd
