2. Install cobbler services;

[[email protected] apps]# yum install -ycobbler httpd tftp-server xinetd dhcp rsync

 

3. Start related services and check the configuration;

Based on the above prompts, we will solve the problem one by one:

1) edit the/etc/cobbler/settings file, find the server option, and change it to the actual IP address of the server (about 384 lines ).

384 rver: 10.0.1.7

2) edit the/etc/cobbler/settings file, find the next_server option, and change it to the actual IP address of the server (About 272 lines ).

272 xt_server: 10.0.1.7

3) execute cobblerget-loaders and the system automatically downloads the loader program to complete the restoration.

[[Email protected] apps] # cobblerget-loaders

4) edit/etc/xinetd. d/rsync and change the disable field configuration in the file to yes to No.

[[Email protected] apps] # Vim/etc/xinetd. d/rsync

Service rsync

{

Disable = No

Flags = IPv6

Socket_type = stream

Wait = No

User = root

Server =/usr/bin/rsync

Server_args = -- daemon

Log_on_failure + = userid

}

5) The system prompts that debmirror is not installed. If it is not a Debian system, you can ignore it.

6) The system prompts you to install pykickstart.

[[Email protected] apps] # Yum install-ypykickstart

7) modify the default cobbler password and change the/etc/cobbler/settings file.

[[Email protected] apps] # OpenSSL passwd-1-salt 'random-phrase-Here '123'

$1 $ random-p $ mzxq/sx848sxgvfwjcozm0
[[Email protected] apps] # Vim/etc/cobbler/settings (Row 3)

101 default_password_crypted: "$1 $ random-p $ mzxq/sx848sxgvfwjcozm0"

8) the system prompts you to install CMAN.

[[Email protected] apps] # Yum install-ycman

 

4. Restart cobbler and check the configuration file.

[[email protected] apps]#/etc/init.d/cobblerd restartStopping cobbler daemon:                                   [  OK  ]Starting cobbler daemon:                                   [  OK  ][[email protected] apps]# cobbler checkThe following are potential configurationitems that you may want to fix: 1 : debmirror package is not installed, itwill be required to manage debian deployments and repositories Restart cobblerd and then run ‘cobblersync‘ to apply changes.

 

5. Import the installation file;

[[email protected] apps]# lsCentOS-6.5-x86_64-bin-DVD1.iso  epel-release-6-8.noarch.rpm[[email protected] apps]#mount -o loop -tiso9660 CentOS-6.5-x86_64-bin-DVD1.iso /mnt[[email protected] apps]# cobbler import--path=/mnt --name=CentOS-6.5-x86_64-bin-DVD1

 

6. Configure the DHCP service;

Edit/etc/cobbler/settings to modify 242 Behavior 1 as follows:

[[email protected] apps]# vim/etc/cobbler/settings242 manage_dhcp: 1

 

Edit/etc/cobbler/DHCP. template to modify the cobbler DHCP management template

[[Email protected] apps] # Vim/etc/cobbler/DHCP. modify the template as follows: Subnet 10.0.1.0 netmask quota 255.255.0 {Option routers 10.0.1.254; optiondomain-name-servers 202.106.0.20; Option subnet-mask quota 255.255.0; range dynamic-BOOTP 10.0.1.100 10.0.1.120; default-lease-time 21600; max-lease-time 43200; next-server $ next_server; [[email protected] apps] #/etc/init. d/xinetd restartstopping xinetd: [OK] Starting xinetd: [OK]

7. Synchronize cobbler configurations;
