Automatic installation of virtual machines with script files under Linux

The hardware needs to be configured, including CPU, memory, NIC, disk, mirror, etc. These in the previous study we can automatically create through the script. After configuring the hardware, start the installation, there are many options we need to manually select, so we can also create automatic answer script. This allows us to implement a virtual machine configuration installation via an instruction that is fully automated and unattended.

1. Build a good yum source;

2. Install kickstart;

Start System-config-kickstart

3. Install the DHCPD. Because to achieve the full automatic control, so to be shared through the network, and can be installed together with many computers!

4. After installation, you need to modify the DHCP configuration file to start the DHCP service.
cp/usr/share/doc/dhcp-4.2.5/dhcpd.conf.example/etc/dhcp/dhcpd.conf---Copy the DHCP service configuration file example to its configuration file, and then modify it

5. Create a script file for the virtual machine

Start making automated installation scripts when you're ready for the above work
Perform the following actions to open the graphical interface for making kickstart, and automatically generate the corresponding script file by selecting it
System-config-kickstart

after generating the ks.cfg file, put him in the shared directory and add permission, put the cloth to/var/www/html out!

And this file can be added at the back with some of what you want.

Last write script file to execute install virtual machine

#！ /bin/bash

Virt-install \

--name \

--ram 1024 \

--file/var/lib/libvirt/images/$1.qcow2,bus=virtio \

--network source=br0,model=virtio \

--extra-args "Ks=http://172.25.254.50/ks.cfg" \ (configured script file)

--vcpus 1 &

Execute, OK.
