Cobbler Automation Installation Linux

Cobbler批量装系统

1. Introduction
Network installation Server suite Cobbler (cobbler) Once upon a time, we have been working as a promising career for migrant workers. Since Red Hat launched Kickstart a few years ago, we circumnavigated worth more. No longer need to carve a CD a platform to install Linux, as long as the PXE, DHCP, TFTP, and the full screen of the dazzling Kickstart script, we can like Harry Potter, Light magic wand, instantly installed hundreds of servers. This pile of gaudy things can not be the average person can understand, no college education, pass English level four, do not want to play around. In a word, this is a very promising, how technical content of the job ah. Unfortunately, Red Hat's latest (Cobbler project was first released around 2008) released the network installation Server suite Cobbler (cobbler), it has installed the Linux network technology threshold, from the college level of education, success down to junior high school, even the shoemaker can learn. For those of us who have been operating in the installation field for many years, experienced, Laojifuli, Costraint migrant brothers, it is a bolt from the blue.
2, System environment preparation
[Email protected] ~]# cat/etc/redhat-release
CentOS Release 6.7 (Final)
[Email protected] ~]# uname-r
2.6.32-573.el6.x86_64
[[email protected] ~]# ifconfig|awk-f "[:]+" ' nr==2 {print $4} '
192.168.1.131
Add Ali Epel Source
[Email protected] ~]# Wget-o/etc/yum.repos.d/epel.repo Http://mirrors.aliyun.com/repo/epel-6.repo
Prepare the Environment software httpd, DHCP, xinetd, rsync, Pykickstart, Cobbler, and Cobbler-web:
[[email protected] ~]# yum install-y httpd dhcp xinetd rsync pykickstart
[email protected] ~]# Yum install-y Cobbler Cobbler-web
Error: Error:package:cobbler-web-2.6.11-7.git95749a6.el6.noarch (Epel)
Requires:django >= 1.4
Missing dependency Package: Djange,djange Dependency package is Python-simplejson, so
[email protected] ~]# Yum install-y Python-simplejson
[Email protected] ~]# wgethttps://kojipkgs.fedoraproject.org//packages/django14/1.4.14/1.el6/noarch/ django14-1.4.14-1.el6.noarch.rpm
[Email protected] ~]# RPM-IVH django14-1.4.14-1.el6.noarch.rpm
3. Configuration files
[Email protected] ~]#/ETC/INIT.D/HTTPD status
HTTPD (PID 1960) is running ...
[Email protected] ~]#/etc/init.d/cobblerd status
Cobblerd (PID 1948) is running ...
[Email protected] ~]# Cobbler Check #检查cobcler配置
The following is potential configuration items and that's want to fix:
1:the ' server ' field in/etc/cobbler/settings must is set to something other than localhost, or kickstarting features WI ll not work. 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/loaders, you could run ' cobbler get-loaders ' to download the M, or, if you are want to handle x86/x86_64 netbooting, your may ensure so you have installed arecentVersion 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:change ' disable ' to ' no ' in/etc/xinetd.d/rsync
6:since Iptables May is running, ensure, 80/443, and 25151 are unblocked
7:debmirror package isn't installed, it'll be required to manage Debian deployments and repositories
8:the default password used by the sample templates for newly installed machines (default_password_crypted IN/ETC/COBBL Er/settings) is still set to ' cobbler ' and should be changed, try: "OpenSSL passwd-1-salt ' Random-phrase-here ' Your-pas Sword-here ' "To generate new one
9:fencing tools were not found, and is 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.
About the problem:
6, the firewall iptables is still running
[Email protected] ~]# Setenforce 0
Setenforce:selinux is disabled
[[Email protected] ~]# service iptables stop
[Email protected] ~]# chkconfig iptables off
[Email protected] ~]# Vim/etc/selinux/config
Selinux=disabled
1, 2, modify the IP address of server,next_server in/etc/cobbler/settings
[Email protected] ~]# sed-i "s/next_server:127.0.0.1/next_server:192.168.1.131/g"/etc/cobbler/settings
[Email protected] ~]# sed-i "s/server:127.0.0.1/server:192.168.1.131/g"/etc/cobbler/settings
Modify cobbler to manage DHCP and TFTP
[Email protected] ~]# sed-i "s/manage_dhcp:0/manage_dhcp:1/"/etc/cobbler/settings
[Email protected] ~]# sed-i "s/manage_rsync:0/manage_rsync:1/g"/etc/cobbler/settings
No duplicate machine is allowed on PXE boot
[Email protected] ~]# sed-i ' s/pxe_just_once:0/pxe_just_once:1/g '/etc/cobbler/settings
8, set the system login root password OpenSSL passwd-1-salt ' guoge ' Your-password-here ' "
[email protected] ~]# OpenSSL passwd-1-salt ' guoge ' 123456 ' # #guoge为干扰内
# #123456为密码
$1$guoge$4kudfv7tavolzgiuxlm2m0
[Email protected] ~]# vim/etc/cobbler/settings
default_password_crypted: "$1$GUOGE$4KUDFV7TAVOLZGIUXLM2M0" # #红色为修改内容

3, 5, modify/etc/xinetd.d/rsync and/etc/xinetd.d/rsync
[Email protected] ~]# sed-i "s/disable = yes/disable = no/g"/etc/xinetd.d/rsync
[[Email protected] ~] #sed-i "s/disable = yes/disa disable = no/g"/etc/xinetd.d/tftp
