Large-scale deployment of unattended Centos7

Given a network architecture diagram, you can communicate with each other if there is any problem during the installation process. I have been tossing for several days. 1. install DHCP, tftp, and HTTP. [Root @ test ~] # Yuminstalldhcptftp-serverhttpd2. modify DHCP, tftp, HTTP configuration file [root @ test ~] #

Specify a network architecture

If you have any problems during the installation process, you can communicate with each other. I have been involved for several days.
1. install DHCP, tftp, and HTTP.

[Root @ test ~] # Yum install dhcp tftp-server httpd

2. modify DHCP, tftp, and HTTP configuration files

[Root @ test ~] # Cp/usr/share/doc/dhcp-4.2.5/dhcpd. conf. example/etc/dhcp/dhcpd. conf
Cp: overwrite '/etc/dhcp/dhcpd. Conf '? Y

After modification, the content of the DHCP file is as follows:

Start DHCP service

Install syslinux to generate pxelinux.0, [root @ test ~] # Yum install syslinux

Configure the tftp service

[Root @ test ~] # Rpm-ql tftp-server
/Etc/xinetd. d/tftp
/Usr/lib/systemd/system/tftp. service
/Usr/lib/systemd/system/tftp. socket
/Usr/sbin/in. tftpd

Configure HTTP service

After modifying the configuration, restart HTTP

[Root @ test conf. d] # systemctl restart httpd. service

Disable selinux and iptables

 

 

Ks file is also modified through the anaconda-ks.cfg, the content is as follows:

 

 

In this case, set the network of the client to start. the following page is displayed:

 

 

 

The above Error is displayed because two nework items are written in the ks file.

 

After waiting, press the up/down key to display the following:

 

The reason for the above problem is that in the default file under the/var/lib/tftpboot/pxelinux. cfg Directory

Menu linux

Append... inst. stage2 =... ks =... delete all stage2 =...

After the installation, the system will automatically restart (at this time, you can adjust the startup sequence in the BIOS). remember to set it to shutdown after the installation.
