Environment:
VMware 12 Virtual Machines
Centos 7 (firewall off and SELinux)
Epel Yum Source
Note:
The default password for the newly installed operating system is admin123
Install operating system default settings file:/VAR/LIB/COBBLER/KICKSTARTS/SAMPLE_END.KS
Cobbler log file:/var/log/cobbler/cobbler.log
Installation steps:
1. Download and install Epel yum source
Command: RPM-IVH
2. Install Cobbler cobbler-web DHCP tftp-server pykickstart httpd rsync xinetd Tree
Yum Install cobbler cobbler-web dhcp tftp-server pykickstart httpd rsync xinetd tree-y

Modify the following three places:
4. Cobbler Check Inspection
You may get an error after executing the command:
Start the following two services:
To perform the check command again:
Cobbler Check
5. Modify the initial password of the root user of the installation system and generate the password using the following command (the 5th after the Cobbler Check command is executed quite a step)
OpenSSL passwd-1-salt ' admin123 ' admin123 '--admin123 for system login username root password
$1$ADMIN123$EIY6RKQOARONGZVRTEO41/--encrypted key
Replace this key in the/etc/cobbler/settings file
default_password_crypted: "$1$admin123$eiy6rkqoarongzvrteo41/"--this is the root user password
6, download the boot operating system files (equivalent to the 2nd after executing the Cobbler check command in step 4)

7. Start RSYNCD Service (equivalent to the 3rd after Cobbler check execution in step 4)
Systemctl Start Rsyncd.service
8. Open the TFTP service (equivalent to the 1th after executing the Cobbler check command in step 4)
Modify the Disable=yes in the/etc/xinetd.d/tftp file to Disable=no

10. Load System image (I use ISO file here)
Mount-t Iso9660-o loop/root/iso/centos-7-x86_64-minimal-1611.iso/mnt
Cobbler Import--path=/mnt/--name=centos-7-x86_64--arch=x86_64

Restart Cobblerd, httpd service
Systemctl Restart Cobblerd.service
Systemctl Restart Httpd.service
