Shell: one click deployment PXE

        shell Scripts can bring us a lot of convenience , Here I write a one click deployment pex Of shell Script

One 、 Front operation

  Add a network card and change it to net1 Pattern

  Two 、 Modify some parameters of the script

Check the name of your new network card , I am here ens36

And change the ip It's worth it and dhcp In the configuration file IP Value and /var/lib/tftpboot/pxelinux.0/default Direction in ftp The address is OK , All changed to the same

If you really don't understand it, you can see that my other blog has detailed instructions ：

         After configuration, you need to configure unattended , The previous blog here also explains in detail how to configure , You can directly follow kickstart That section starts to configure

PXE&&kickstart Principle and configuration _IT.cat The blog of -CSDN Blog

         After configuring unattended, we can ks.cfg Keep the file , In the future, you don't need to configure the unattended operation alone again, just pull the file directly

  verification

The verification method is also detailed in my last blog It is mainly to create virtual machines and unattended file storage locations

Here is a direct demonstration of the process after execution

 

Just wait here , It will take a long time , Be patient
