Cobbler自动化批量部署CentOS6.5系统

Cobbler作为一个预备工具，使批量部署Red Hat/Centos/Fedora系统更容易，同时也支持Suse和Debian系统的部署。

它提供以下服务集成：

　　* PXE服务支持
　　* DHCP服务管理
　　* DNS服务管理
　　* Kickstart服务支持
　　* yum仓库管理
Cobbler客户端Koan支持虚拟机安装和操作系统重新安装功能.

一、cobbler安装准备

　　系统：CentOS6.5 64位
　　IP地址：192.168.132.128

1.关闭selinux

[root@localhost ~]#vim /etc/selinux/config
#SELINUX=enforcing            #注释掉
#SELINUXTYPE=targeted      #注释掉
SELINUX=disabled                 #增加

:wq!  #保存退出
[root@localhost ~]#setenforce 0 	 #使配置立即生效
[root@localhost ~]#sestatus		 #重启后查看

2.关闭iptables

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

3.下载epel源的rpm安装包并安装cobbler软件

[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.检查配置执行:

[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'">

报错了
经过网上查找这样解决如下：

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

*** TASK COMPLETE ***

再次检查配置:

[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.

根据cobbler check 检测所的信息，进行相应配置：

1.配置tftp-server与rsync 设置rsync和tftp服务开机启动.

编辑/etc/cobbler/settings文件，找到 server选项，修改为适当的ip地址，本实例配置ip为：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与rsync.

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

3.提示说debmirror没安装。如果不是安装 debian之类的系统，此提示可以忽略。

4.安装pykickstart.

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

5.生成密码串(设置默认 root 用户的密码):

[root@localhost ~]# openssl passwd -1 -salt 'random-phrase-here' 'saneri'
$1$random-p$3a6Zq0MlL6NuutFGzwxGJ.
然后将结果替换 /etc/cobbler/settings 文件中的
default_password_crypted:

根据提示基本配置完成了，OK再来执行检查.

[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服务　

修改/etc/cobbler/dhcp.template，此文件是cobbler管理dhcp的模板和/etc/dhcp/dhcpd.conf文件，两个配置内容一样
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 {　　　　　　　　　#设置网段
option routers 192.168.132.1;　　　　　　　　#设置网关
option subnet-mask      255.255.255.0;　　　#子网掩码
range dynamic-bootp 192.168.132.30 192.168.132.35;    #动态IP范围
option domain-name-servers 8.8.8.8,8.8.4.4;   #DNS地址
default-lease-time 43200;　　　　　　　　　　　　 #缺省租约时间
max-lease-time 86400;　　　　　　　　#最大租约时间
log-facility local7;　　　　　　　　　#
filename="pxelinux.0";
next-server $next-server;　　　　　　#指定引导服务器
}

EOF

重新启动相关服务

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