RHEL6 semi-automatic network installation

Operating System: RHEL6 sometimes does not need to deploy so many servers, but only a few servers, but it does not have a fully automated Kickstart environment, and does not want to go to the next step on each platform, you can use semi-automatic functions. The ks. cfg file is indispensable: # platform = x86, AMD64, or IntelEM64T # version = DEVEL # Firewallconfigurationfirewal

Operating System: RHEL6

Sometimes there is no need to deploy so many servers, just a few servers, but there is no fully-automated Kickstart environment. If you don't want to perform the next step on each platform, you can use semi-automated deployment.

RHEL6 automatically responds to file download:

Free in http://linux.linuxidc.com/

The username and password are both www.linuxidc.com

The specific download directory is available for installation on/July 15,/July 28,/RHEL6 semi-automatic network.

The partition is the LVM used, which may be convenient for future applications. The root password is 123456. The above script also adds some optimization parameters in the script after installation, which can be modified based on the actual situation.

To put it simply, how can we implement semi-automatic functions? At least one http server should have a yum source to ensure smooth network access. When the disc starts, press the Tab key on the menu interface to add the ks file path:

Use "ks =" to write the specific path. It can be ftp or http. We recommend that you use http because it is easier to deploy. After you press enter, the installation is automatically completed. You don't have to worry about the next step. If no DHCP is available, you may need to specify the IP address first.
