Experimental environment

1) Installation of related services that cobbler depends on

[[email protected] ~]# yum-y install TFTP tftp-server DHCP httpd  #pxe可通过http或者ftp等方式提供安装文件 [[email protected] ~]# Yum Install-y syslinux  #提供pxe安装所需要的pxelinux. 0 files [[email protected] ~]# vim/etc/dhcp/dhcpd.conf    option Domain-name "test.com";    Option Domain-name-servers 8.8.8.8,114.114.114.114;    Default-lease-time;    Max-lease-time 7200;    Log-facility Local7;    Subnet 192.168.4.0 netmask 255.255.255.0{  #ip地址范围必须跟本机ip一致            range 192.168.4.1 192.168.4.100;            option routers 192.168.4.116;            FileName "pxelinux.0";            Next-server 192.168.4.116;    } [Email protected] ~]# systemctl start dhcpd  #启动dhcp [[email protected] ~]# cat/var/lib/dhcpd/dhcpd.leases  # You can see the lease of the IP by viewing the file [email protected] ~]# systemctl start httpd tftp.socket  #启动http, tftp

2) Install the Cobbler1, install the Cobbler, start the service, and then perform the Cobbler check

[[email protected] ~]# yum-y install cobbler[[email protected] ~]# systemctl start cobblerd[[email  Protected] ~]# Cobbler Check the following is potential configuration items that you could want to fix:1: the ' Server ' field in/etc/cobbler/settings must is set to something other than localhost, or kickstarting features would not wo  Rk.    This should is a resolvable hostname or IP for the boot server as reachable by all machines that would use it. 2:for PXE to be functional, the ' next_server ' field in/etc/cobbler/settings must is 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 is missing from/var/lib/cobbler/load ERS, you could run ' cobbler get-loaders ' to download them, or, if you have want to handle x86/x86_64 netbooting, your may ens Ure the installed a *recent* version of the Syslinux package installed and CAn Ignore this message entirely.  Files in this directory, should want to support all architectures, should include pxelinux.0, MENU.C32, Elilo.efi, and Yaboot.    The ' Cobbler get-loaders ' command is the easiest-to resolve these requirements. 5:enable and start Rsyncd.service with Systemctl 6:debmirror package isn't installed, it'll be required to Manag E Debian deployments and repositories 7:the default password used by the sample templates for newly installed machine S (default_password_crypted in/etc/cobbler/settings) is still set to ' cobbler ' and should are changed, try: "OpenSSL PASSW D-1-salt ' random-phrase-here ' your-password-here ' "to generate new one 8:fencing tools were not found, and is req Uired 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.

2, to check out the various errors to deal with the corresponding

3. Restart Cobbler

[Email protected] ~]# systemctl restart Cobblerd[[email protected] ~]# Cobbler Check the    following is potential conf  Iguration items want to fix:    1:debmirror package is not installed, it'll be required to manage Debian Deployments and repositories    Restart Cobblerd and then run ' Cobbler Sync ' to apply changes.[ [Email protected] ~]# Cobbler sync  #忽略debian的配置

3) Configure Cobbler1, create centos7.2 Cobbler objects

[Email protected] ~]# mount/dev/cdrom/mnt  #挂载centos7.2 optical drive [[email protected] ~]# Cobbler import--name= Centos-7.2-x86_6--path=/mnt  #创建cobbler对象组, this process is time consuming [[email protected] ~]# Cobbler distro List  # View the corresponding distribution    centos-7.2-x86_64

The image is automatically imported into the/var/www/cobbler/ks_mirror, followed by HTTP to obtain the installation source;

By default, cobbler also generates a minimized installed kickstart file, which is/VAR/LIB/COBBLER/KICKSTARTS/SAMPLE_END.KS by default. If we want to customize the kickstart file, you can do the following:

[[email protected] ~]# CP centos7.2.cfg/var/lib/cobbler/kickstarts/  #centos7.2.cfg for custom kickstart files [email Protected] ~]# Cobbler profile add--name=centos-7.2-x86_64-custom--distro=centos-7.2-x86_64--kickstart=/var/lib/ Cobbler/kickstarts/centos7.2.cfg  #--distro to correspond to the Distro object created in the previous step [[email protected] ~]# Cobbler profile list    centos-7.2-x86_64    Centos-7.2-x86_64-custom

Check that the httpd and TFTP service-related directories have created the appropriate files:

[[email protected] ~]# ll/var/www/cobblertotal 0drwxr-xr-x. 4 root root 16:06 Oct imagesdrwxr-xr-x. 5 root root (Oct) 16:04 ks_mirrordrwxr-xr-x. 2 root root 16:06 Oct linksdrwxr-xr-x. 2 root root 6 May 20:41 localmirrordrwxr-xr-x. 2 root root Notoginseng Oct 10:29 miscdrwxr-xr-x. 2 root root 6 May 20:41 pubdrwxr-xr-x. 2 root root 6 May 20:41 rendereddrwxr-xr-x. 2 root root 6 May 20:41 repo_mirrordrwxr-xr-x. 2 root root (OCT) 10:29 svc[[email protected] ~]# ll/var/lib/tftpboot/total 300drwxr-xr-x 3 root root + Oc T-15:00 bootdrwxr-xr-x. 2 root root 6 May 20:41 etcdrwxr-xr-x. 2 root root 15:00 Oct-grubdrwxr-xr-x. 4 root root 16:06 Oct imagesdrwxr-xr-x. 2 root root 6 May 20:41 images2-rw-r--r--. 1 root root 26268 Mar 6 memdisk-rw-r--r--2 root root 54964 may 16:49 menu.c32drwxr-xr-x. 2 root root 6 20:41 ppc-rw-r--r--2 root root 16794 may 16:49 pxelinux.0drwxr-xr-x. 2 Root ROot Oct 15:00 pxelinux.cfgdrwxr-xr-x. 2 root root Oct 15:00 s390x-rw-r--r--2 root root 198236 may 16:49 Yaboot

Test installation: (only test the Cobbler self-built kickstart, success)

2. Create a centos6.5 Cobbler object

Mount /dev/cdrom/mnt  ~]# Cobbler import--name=centos-6.7-x86_64--path=/mnt   ~]# Cobbler distro list  #查看对应的distribution    CentOS-6.7-x86_64    CentOS -7.2-~]# Cobbler Profile list    CentOS-6.7-x86_64    CentOS-7.2-x86_64    CentOS-7.2-x86_64-custom

Test Installation 6.5: Success

4) Cobbler Web management interface

[Email protected] ~]# yum-y install cobbler-web[[email protected] ~]# vim/etc/cobbler/modules.conf    ...    [Authentication]    module = Authn_pam   #使用authn_pam, local user authentication modules    ... [Email protected] ~]# useradd cbadmin[[email protected] ~]# echo 123456|passwd--stdin cbadmin    ... [Email protected] ~]# vim/etc/cobbler/users.conf ...    [Admins]    admin = "Cbadmin" [[email protected] ~]# systemctl restart Cobblerd
