Network Install Linux System

Network boot installation Detailed steps: (Two ways vsftp and NFS)

2. Installing the Software

   Yum install TFTP tftp-server vsftpd DHCP xinetd syslinux-y

4. Modify xinetd to open tftp

   Vim/etc/xinetd.d/tftp

   Disable = no----find this line and modify Yes to No

6. Mount the mounting media.

   Because my installation media is placed on the physical machine windows, I set the media to a shared folder and then use the command below to mount the Windows shared folder to the Linux directory.

   Mount.cifs-o username= "Administrator", password= "111111"//192.168.80.135/ax4sp2/mnt/winf/

8. Create a new DVD directory in the FTP pub directory, and then loop the installation media to the FTP Pub/dvd directory

   Mkdir/var/ftp/pub/dvd

   cd/mnt/winf/

   Mount-o Loop centos.iso/var/ftp/pub/dvd/

   cd/var/ftp/pub/dvd/

   LS-----View the files that are mounted.

   Documents highavailability isolinux Packages resilientstorage Server

   EFI images loadbalancer repodata scalablefilesystem TRANS. TBL

10. Copy isolinux The following file to Tftpboot

    CD isolinux/

    CP./*/var/lib/tftpboot/-arf

12. Copy pxelinux.0 to Tftpboot

    cd/var/lib/tftpboot/

    cp/usr/share/syslinux/pxelinux.0./-arf

14. Create a new pxelinux.cfg directory, copy the Pxelinux.cfg file to the directory and rename it to default
    

    mkdir pxelinux.cfg

    CD pxelinux.cfg/

    Cp/var/ftp/pub/dvd/isolinux/isolinux.cfg Default

16. Configure DHCP

    Vim/etc/dhcp/dhcpd.conf

    Write the following: write the IP address according to the actual situation

    Subnet 192.168.1.0 netmask 255.255.255.0----network segment, mask

    {

    Range 192.168.1.2 192.168.1.254;----Range

    FileName "pxelinux.0";

    Next-server 192.168.1.104;-----The native server address

    }

18. Start the service:

    /ETC/INIT.D/DHCPD restart

    /etc/init.d/xinetd restart

    /ETC/INIT.D/VSFTPD restart

    Chkconfig TFTP on

20. Boot Select network installation, you can install the system.

Note the point:

1. If you use NFS installation, you need to edit the exports file and put the media in.

   Mkdir/iso

   Mount-o Loop Centos.iso/iso

   Vim/etc/exports---Edit enter the following content
   

   /iso * (RO)

   Then, start the NFS service

   /etc/init.d/rpcbind restart

   /etc/init.d/nfs restart

   Then power on select Network installation, prompted to choose the installation method when the NFS access to know.

2. The 22nd line of the default file in the/var/lib/tftpboot/pxelinux.cfg/directory can also be added to the Ks.cfg file address to automatically install the system.

   The following format: Append ks=nfs:192.168.1.11:/opt/ks.cfg initrd=initrd.img Adding this content on line 22 allows for automatic installation of the system.
