Cobbler做爲一個預備工具，使批量部署Red Hat/Centos/Fedora系統更容易，同時也支持Suse和Debian系統的部署。html

它提供如下服務集成：python

　　* PXE服務支持
　　* DHCP服務管理
　　* DNS服務管理
　　* Kickstart服務支持
　　* yum倉庫管理
Cobbler客戶端Koan支持虛擬機安裝和操做系統從新安裝功能.linux

1、cobbler安裝準備ios

　　系統：CentOS6.5 64位
　　IP地址：192.168.132.128git

1.關閉selinuxgithub

[root@localhost ~]#vim /etc/selinux/config
#SELINUX=enforcing            #註釋掉
#SELINUXTYPE=targeted      #註釋掉
SELINUX=disabled                 #增長

:wq!  #保存退出
[root@localhost ~]#setenforce 0 	 #使配置當即生效
[root@localhost ~]#sestatus		 #重啓後查看

2.關閉iptablesweb

[root@localhost ~]#chkconfig iptables off
[root@localhost ~]#/etc/init.d/iptables stop

3.下載epel源的rpm安裝包並安裝cobbler軟件shell

[root@localhost ~]#wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
[root@localhost ~]#rpm -ivh epel-release-6-8.noarch.rpm
[root@localhost ~]#yum -y install cobbler cobbler-web httpd rsync tftp-server xinetd dhcp python-ctypes debmirror pykickstart fence-agents cman

[root@localhost ~]# /etc/init.d/cobblerd start
Starting cobbler daemon:                                   [  OK  ]
[root@localhost ~]# /etc/init.d/httpd start
Starting httpd: 																					 [  OK  ]
[root@localhost ~]#

4.檢查配置執行:vim

[root@localhost ~]# cobbler check
Traceback (most recent call last):
  File "/usr/bin/cobbler", line 36, in <module>
    sys.exit(app.main())
  File "/usr/lib/python2.6/site-packages/cobbler/cli.py", line 657, in main
    rc = cli.run(sys.argv)
  File "/usr/lib/python2.6/site-packages/cobbler/cli.py", line 270, in run
    self.token         = self.remote.login("", self.shared_secret)
  File "/usr/lib64/python2.6/xmlrpclib.py", line 1199, in __call__
    return self.__send(self.__name, args)
  File "/usr/lib64/python2.6/xmlrpclib.py", line 1489, in __request
    verbose=self.__verbose
  File "/usr/lib64/python2.6/xmlrpclib.py", line 1253, in request
    return self._parse_response(h.getfile(), sock)
  File "/usr/lib64/python2.6/xmlrpclib.py", line 1392, in _parse_response
    return u.close()
  File "/usr/lib64/python2.6/xmlrpclib.py", line 838, in close
    raise Fault(**self._stack[0])
xmlrpclib.Fault: <Fault 1: "<class 'cobbler.cexceptions.CX'>:'login failed'">

報錯了
通過網上查找這樣解決以下：centos

[root@localhost ~]# /etc/init.d/cobblerd restart

*** TASK COMPLETE ***

再次檢查配置:

[root@localhost ~]# 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 : change 'disable' to 'no' in /etc/xinetd.d/rsync
5 : file /etc/xinetd.d/rsync does not exist
6 : comment out 'dists' on /etc/debmirror.conf for proper debian support
7 : comment out 'arches' on /etc/debmirror.conf for proper debian support
8 : ksvalidator was not found, install pykickstart
9 : 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

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

根據cobbler check 檢測所的信息，進行相應配置：

1.配置tftp-server與rsync 設置rsync和tftp服務開機啓動.

編輯/etc/cobbler/settings文件，找到 server選項，修改成適當的ip地址，本實例配置ip爲：192.168.132.128

sed -i 's@manage_dhcp: 0@manage_dhcp: 1@g' /etc/cobbler/settings
sed -i 's@next_server: 127.0.0.1@next_server: '192.168.132.128'@g' /etc/cobbler/settings
sed -i 's@server: 127.0.0.1@server: '192.168.132.128'@g' /etc/cobbler/settings

2.配置tftp-server與rsync.

sed -i 's/disable.*$/disable = no/g' /etc/xinetd.d/tftp
sed -i 's/disable.*$/disable = no/g' /etc/xinetd.d/rsync

3.提示說debmirror沒安裝。若是不是安裝 debian之類的系統，此提示能夠忽略。

4.安裝pykickstart.

[root@localhost ~]# yum install pykickstart -y

5.生成密碼串(設置默認 root 用戶的密碼):

[root@localhost ~]# openssl passwd -1 -salt 'random-phrase-here' 'saneri'
$1$random-p$3a6Zq0MlL6NuutFGzwxGJ.
而後將結果替換 /etc/cobbler/settings 文件中的
default_password_crypted:

根據提示基本配置完成了，OK再來執行檢查.

[root@localhost cobbler]# /etc/init.d/cobblerd restart
Stopping cobbler daemon:                                   [  OK  ]
Starting cobbler daemon:                                   [  OK  ]

[root@localhost cobbler]# cobbler check
The following are potential configuration items that you may want to fix:

1 : service dhcpd is not running
2 : file /etc/xinetd.d/rsync does not exist
3 : comment out 'dists' on /etc/debmirror.conf for proper debian support
4 : comment out 'arches' on /etc/debmirror.conf for proper debian support

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

配置dhcp服務　

修改/etc/cobbler/dhcp.template，此文件是cobbler管理dhcp的模板和/etc/dhcp/dhcpd.conf文件，兩個配置內容同樣
cat > /etc/cobbler/dhcp.template <<EOF

ddns-update-style interim;

allow booting;
allow bootp;

ignore client-updates;
set vendorclass = option vendor-class-identifier;

option pxe-system-type code 93 = unsigned integer 16;

subnet 192.168.132.0 netmask 255.255.255.0 {　　　　　　　　　#設置網段
		 option routers 192.168.132.1;　　　　　　　　#設置網關
		 option subnet-mask      255.255.255.0;　　　#子網掩碼
     range dynamic-bootp 192.168.132.30 192.168.132.35;    #動態IP範圍
     option domain-name-servers 8.8.8.8,8.8.4.4;   #DNS地址
     default-lease-time 43200;　　　　　　　　　　　　 #缺省租約時間
		 max-lease-time 86400;　　　　　　　　#最大租約時間
		 log-facility local7;　　　　　　　　　#
		 filename="pxelinux.0";
		 next-server $next-server;　　　　　　#指定引導服務器
}		

EOF

從新啓動相關服務

[root@localhost cobbler]# /etc/init.d/dhcpd restart
Starting dhcpd:                                            [  OK  ]

[root@localhost dhcp]# /etc/init.d/cobblerd restart
Stopping cobbler daemon:                                   [  OK  ]
Starting cobbler daemon:                                   [  OK  ]

[root@localhost dhcp]# /etc/init.d/xinetd restart
Stopping xinetd:                                           [  OK  ]
Starting xinetd:                                           [  OK  ]
