First, set up an unattended server to install software (PXE + DHCP+TFTP+ Kickstart+ FTP) IP:172.168.1.200

System version: CentOS Linux release 7.4.1708 (Core)

Close selinux,firewalld

[root@localhost] # axel-n 100 http://mirror.nsc.liu.se/centos-store/7.4.1708/isos/x86_64/CentOS-7-x86_64-Minimal-1708.iso

[root@localhost ~] # mount CentOS-7-x86_64-Minimal-1708.iso / media/

[root@localhost ~] # yum-y install vsftpd tftp tftp-server xinetd system-config-kickstart syslinux

Second, modify the configuration file

[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 / tftpboot # modify disable = no # modify per_source = 11 cps = 100 2 flags = IPv4}

[root@localhost ~] # cp/ usr/share/doc/dhcp-4.2.5/dhcpd.conf.example / etc/dhcp/dhcpd.conf

[root@localhost ~] # > / etc/dhcp/dhcpd.conf

[root@localhost ~] # vim / etc/dhcp/dhcpd.conf

Subnet 172.168.1.0 netmask 255.255.255.0 {range 172.168.1.100 172.168.1.199 option domain-name-servers 172.168.1.1 option domain-name "internal.example.org"; option routers 172.168.1.1 option broadcast-address 172.168.1.255mit.defaultmurf LeaseMutual time 600 makesleaseMAXMAXMAXEMAXEMAXEMAXMAXEMAXE 7200 ExtMutual server 172.168.1.200 sectional filename "pxelinux.0";} III, configure tftp to share files.

[root@localhost ~] # mkdir / tftpboot

[root@localhost ~] # mkdir / tftpboot/pxelinux.cfg

[root@localhost ~] # cp / usr/share/syslinux/pxelinux.0 / tftpboot/

[root@localhost ~] # cp / media/images/pxeboot/initrd.img / tftpboot/

[root@localhost ~] # cp / media/images/pxeboot/vmlinuz / tftpboot/

[root@localhost ~] # cp / media/isolinux/isolinux.cfg / tftpboot/pxelinux.cfg/default

Modify default, specify the way to install the operating system and the ks.cfg file path (modify the first line and 64 lines do not change) 1 default linux # the first line is changed to this way 64 append initrd=initrd.img inst.repo= ftp://172.168.1.200/pub inst.ks= ftp://172.168.1.200/ks.cfg # 64 lines are modified to configure the unattended package

[root@localhost yum.repos.d] # pwd

/ etc/yum.repos.d

[root@localhost yum.repos.d] # vim server.repo

[centos7] name=my-centos7baseurl= file:///var/ftp/pubenabled=1gpgcheck=0

[root@localhost ~] # cd / var/ftp/pub/

[root@localhost] # cp-r / media/*.

[root@localhost ~] # cp anaconda-ks.cfg / var/ftp/ks.cfg

[root@localhost ~] # egrep-v "^ # | ^ $" / var/ftp/ks.cfg

[root@localhost ~] # systemctl enable vsftpd xinetd dhcpd

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