-- httpd dhcp tftp cobbler cobbler-web pykickstart 安裝

Centos7鏡像阿裡雲網址:http://mirrors.aliyun.com/epel/

[[email protected] ~]# rpm -ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm

[[email protected] ~]# yum -y install httpd dhcp tftp cobbler cobbler-web pykickstart  xinetd

[[email protected] ~]# systemctl start cobblerd.service xinetd.service httpd.service

[[email protected] ~]# systemctl enable cobblerd.service xinetd.service httpd.service

[[email protected] conf.d]# cobbler check

The following are potential configuration items that you may want to fix:

1 : The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work.  This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.

2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.

3 : change 'disable' to 'no' in /etc/xinetd.d/tftp

4 : Some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely.  Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements.

5 : enable and start rsyncd.service with systemctl

6 : debmirror package is not installed, it will be required to manage debian deployments and repositories

7 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one

8 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

Restart cobblerd and then run 'cobbler sync' to apply changes.

[[email protected] tmp]# koan --replace-self --server=192.168.10.10 --profile=Centos7.6-x86_64

建議：裝機請設定專有的裝機vlan網段，防止影響其它網段環境

--cobbler web管理介面

--cobbler 自動安裝

1. 首先規劃好要上線的主機的相關資訊

如profile安裝哪個作業系統、分區等、預配置設定的ip位址、主機名、子網、網關、dns、角色等

1. 例如：

主機名：linux-node1.ald8.com

MA位址：00:50:56:20:27:EE

Ip:192.168.10.160

Mask：255.255.255.0

Gateway：192.168.10.2

DNS：192.168.10.2

1. 設定安裝

[[email protected] ~]# cobbler system add --name=linux.node1.ald8.com --mac=00:50:56:20:27:EE --profile=Centos7.6-xCentos7.6-x86_64 --ip-address=192.168.10.60 --subnet=255.255.255.0 --gateway=192.168.10.2 --inter192.168.10.2" --kickstart=/var/lib/cobbler/kickstarts/sample_end.ks

開啟那台00:50:56:20:27:EE的主機就會自動安裝了
