Seven test PXE boot installation<\/p>\n
1, the client set boot from the network (in fact, do not set the local network can not be found naturally go to find), you can see the installation interface<\/p>\n
2, select the language <\/p>\n
3, OK<\/p>\n
4. Select the keyboard (us) OK<\/p>\n
5, select the media location (NFS Directory) OK<\/p>\n
6, configure the network (the default can) OK<\/p>\n
7, Setting Up NFS Services (NFS server name: 192.168.1.10 ## NFS server address
\n CentOS directroy: \/ mnt ## ISO stowed position) OK<\/p>\n
8, where the installation interface appears normal, prove no problem (with CD-ROM to install a pattern)<\/p>\n
## This is the realization of the PXE boot installation, you want to have unattended configuration Kickstart!<\/p>\n
Eight, install the desktop environment<\/p>\n
## The following operation is performed directly in the virtual machine, the non-terminal connection! (Not necessary)<\/p>\n
yum grouplist | grep -iP “(x window system|desktop)”<\/p>\n

\n\u00b7 Boot Loader Options<\/p>\n
Mounting Type
\n install a new boot loader: Check the
\n installation options
\n Boot Record (MBR) on the primary boot loader installation
\n\u00b7 partition information
\n master boot record
\n to clear the Master Boot Record: Check the
\n partition
\n to remove all existing partitions: Check the
\n disk label
\n to initialize the disk label : check the
\n layout
\n add partition (with the same real machine installed)
\n\u2022 network configuration
