centos7.2 Installing the Cobbler and installing the system

system CentOS7.2

To learn the CentOS6.5 system can look at this predecessor's link, here no longer introduce

In fact, centos6.5 with 7.2 words, that is centos6.5 more than one rsync, and centos7.2 do not need to configure rsync, the other operations are the same

Let's put more of that part down.

and the centos6.5 system (I'm using the VMware Workstation virtual way) will prompt a

We need you to hit the carriage return here.

Start the operation on centos7.2 below

1. Turn off SELinux

Sed-in ' s/selinux=enforcing/selinux=disabled/'/etc/selinux/configsetenforce 0

2. Turn off the firewall

Systemctl Disable Firewalld.servicesystemctl stop firewalld.servicesystemctl is-enabled firewalld.service

3. Install Epel-release, 163 source

Yum-y install Epel-release cd/etc/yum.repos.d/; Wget Http://mirrors.163.com/.help/CentOS7-Base-163.repo; Cd

4. View Cobbler Package

Yum Search All Cobbler

5. Installing Cobbler

Yum-y Install Cobbler Cobbler-web

6. Install DHCP httpd xinetd

Yum-y Install DHCP httpd xinetd

7. Add Cobbler httpd dhcp xinetd to boot

Chkconfig cobblerd onchkconfig httpd onchkconfig dhcpd onchkconfig xinetd on

8. Configuring the Environment

Back up a profile first in case of a contingency

Cp/etc/cobbler/settings{,.bak}

next_server:10.0.0.103

server:10.0.0.103

manage_dhcp:0#设置为1时, the DHCP Manager that opens cobbler is not turned on, because the test is not turned on and there is nothing to configure the DHCPD configuration file

manage_rsync:1#设置为1时, turn on the Cobbler Rsync manager

9. Generate the password string (this password is the root password after the installation of the system)

Format:

OpenSSL passwd-1-salt "any character" "Password"

OpenSSL passwd-1-salt "Cobbler" "CentOS"

$1$cobbler$dwl2fhtharta2hj5veuzk.

Vim/etc/cobbler/settings

default_password_crypted: "$1$cobbler$dwl2fhtharta2hj5veuzk."

10. Enable xinetd

Change the value of disable to "no"

And the last one is for the Debian system. I don't need to install it.

14. Mount the disk, import the system image, the centos7.2 system is imported here

Cobbler Import--path=/mnt/--name=centos7.2

If you have a problem, check it with cobbler and you can speed up the wrong time.

The KS file used above is the default, and the system that is installed is also minimized.

After doing this, you can install the system without the need for human intervention.

Here's a hint.

Sometimes you may need to install a system in bulk to copy the name of the label to the first line of the boot file.

The location of the boot program is
