Although there are many ways to install Linux on a machine, installing over the network with the help of a kickstart file is the most efficient option. The installation process can be automated requiring minimal human intervention. A kickstart file can be kept on a server and read by individual machines during the installation process. In the recipe, we will outline steps to install Linux on a number of Hadoop nodes over the network.
Before getting started, we need to verify that the DHCP server and FTP server are running correctly on the administrative machine.
Use the following command on the administrator machine to check if the DHCP server is working properly:
ps -ef | grep dhcp
If this command gives non-empty output, then it is working correctly, otherwise, we need to start the service with the following command:
sudo service dhcpd start
Similarly, the following command can be used to check the FTP server on the administrator machine...
