Cobbler服务器系统: CentOS 6.6 64位
Cobbler版本: cobbler-2.6.11
IP地址：192.168.166.136
1、安装epel库
rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
2、安装依赖包
yum -y install cobbler tftp tftp-server xinetd dhcp httpd rsync pykickstart debmirror python-ctypes cman
3、配置http
sed -i ‘s/^#ServerName www.example.com:80/ServerName 0.0.0.0:80/g‘ /etc/httpd/conf/httpd.conf chkconfig httpd on /etc/init.d/httpd start
4、配置tftp和rsync
sed -i ‘s/disable\t= yes/disable\t= no/g‘ /etc/cobbler/tftpd.template sed -i ‘s/disable\t= yes/disable\t= no/g‘ /etc/xinetd.d/rsync chkconfig xinetd on /etc/init.d/xinetd start
5、配置cobbler相关参数
[[email protected]_166_136 ~]#sed -i ‘s/^@dists/#@dists/g;s/^@arches/#@arches/g‘ /etc/debmirror.conf
#生成root密码的密文，cobber客户端使用，该机器也必须能使用这个密码，否则执行cobbler sync/cobbler get-loaders报登录失败
[[email protected]_166_136 kickstarts]# openssl passwd -1 -salt ‘‘ ‘123456‘
$1$$RmyPVMlhpXjJj8iv4w.Ul.
[[email protected]_166_136 ~]#vi /etc/cobbler/settings
default_password_crypted: "$1$$RmyPVMlhpXjJj8iv4w.Ul."
[[email protected]_166_136 ~]#IP=$(ifconfig |grep -A 2 "eth0 " |grep ‘inet addr‘|awk ‘{print $2}‘|awk -F: ‘{print $2}‘)
[[email protected]_166_136 ~]#sed -i "s/^next_server.*$/next_server: $IP/g" /etc/cobbler/settings
[[email protected]_166_136 ~]#sed -i "s/^server.*$/server: $IP/g" /etc/cobbler/settings
[[email protected]_166_136 ~]#sed -i "s/^manage_dhcp.*$/manage_dhcp: 1/g" /etc/cobbler/settings
[[email protected]_166_136 ~]#sed -i "s/^pxe_just_once.*$/pxe_just_once: 1/g" /etc/cobbler/settings
[[email protected]_166_136 ~]#sed -i "s/^manage_rsync.*$/manage_rsync: 1/g" /etc/cobbler/settings
#查看修改的配置
[[email protected]_166_136 ~]#grep -E "^default_password_crypted|^next_server|^server|^pxe_just_once|^manage_rsync|^manage_dhcp" /etc/cobbler/settings
6、配置dhcp服务器
#修改subnet信息
[[email protected]_166_136 ~]#vi /etc/cobbler/dhcp.template
subnet 192.168.166.0 netmask 255.255.255.0 {
#option routers 192.168.166.1;
option domain-name-servers 192.168.166.2;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.166.10 192.168.166.60;
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
class "pxeclients" {
match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";
if option pxe-system-type = 00:02 {
filename "ia64/elilo.efi";
} else if option pxe-system-type = 00:06 {
filename "grub/grub-x86.efi";
} else if option pxe-system-type = 00:07 {
filename "grub/grub-x86_64.efi";
} else {
filename "pxelinux.0";
}
}
}
[[email protected]_166_136 ~]#echo "DHCPDARGS=eth0" >/etc/sysconfig/dhcpd
#检查cobber配置是否有误 ------下面这个问题，已确认有该文件，不知道为什么还是提示。。我这里忽略
[[email protected]_166_136 kickstarts]# cobbler check
The following are potential configuration items that you may want to fix:
1 : file /etc/xinetd.d/rsync does not exist
Restart cobblerd and then run ‘cobbler sync‘ to apply changes.
chkconfig dhcpd on
chkconfig cobblerd on
cobbler get-loaders
service cobblerd start
cobbler sync
#测试dhcp服务器配置是否正确
dhcpd
service dhcpd start
设置cobbler相关服务启动脚本
vi /etc/rc.d/init.d/cobbler #!/bin/sh # chkconfig: - 80 90 # description:cobbler case $1 in start) /etc/init.d/httpd start /etc/init.d/xinetd start /etc/init.d/dhcpd start /etc/init.d/cobblerd start ;; stop) /etc/init.d/httpd stop /etc/init.d/xinetd stop /etc/init.d/dhcpd stop /etc/init.d/cobblerd stop ;; restart) /etc/init.d/httpd restart /etc/init.d/xinetd restart /etc/init.d/dhcpd restart /etc/init.d/cobblerd restart ;; status) /etc/init.d/httpd status /etc/init.d/xinetd status /etc/init.d/dhcpd status /etc/init.d/cobblerd status ;; sync) cobbler sync ;; *) echo "Input error,please in put ‘start|stop|restart|status|sync‘!"; exit 2>&1 >/dev/null & ;; esac chmod +x /etc/rc.d/init.d/cobbler chkconfig cobbler on service cobbler restart
7、制作镜像
mkdir -p /data/iso/tmp rz -be #上传ios至/data/iso目录 mount -t iso9660 -o loop /data/iso/CentOS-6.6-x86_64-bin-DVD1.iso /data/iso/tmp #将iso导入到cobber,切记必须切换到/var/www/cobbler/ks_mirror执行,该目录开启了http访问 cd /var/www/cobbler/ks_mirror cobbler import --path=/data/iso/tmp --name=CentOS-6.6-x86_64 --arch=x86_64
8、设置kickstarts安装配置文件
#定制系统安装及脚本设置,重要 #1、不支持中文,切记 #2、不支持bash里面的转义字符 #3、自定义脚本，请使用http的方式执行 cat /var/lib/cobbler/kickstarts/CentOS-6.6-x86_64.ks # kickstart template for Fedora 8 and later. # (includes %end blocks) # do not use with earlier distros #platform=x86, AMD64, or Intel EM64T # System authorization information auth --useshadow --enablemd5 # System bootloader configuration bootloader --location=mbr # Partition clearing information clearpart --all --initlabel # Use text mode install text # Firewall configuration firewall --disabled # Run the Setup Agent on first boot firstboot --disable # System keyboard keyboard us # System language lang en_US.UTF-8 # Use network installation url --url=$tree # If any cobbler repo definitions were referenced in the kickstart profile, include them here. $yum_repo_stanza # Network information $SNIPPET(‘network_config‘) # Reboot after installation reboot #Root password rootpw --iscrypted $default_password_crypted # SELinux configuration selinux --disabled # Do not configure the X Window System skipx # System timezone timezone Asia/Shanghai # Install OS instead of upgrade install # Clear the Master Boot Record zerombr # Allow anaconda to partition the system as needed autopart %pre $SNIPPET(‘log_ks_pre‘) $SNIPPET(‘kickstart_start‘) $SNIPPET(‘pre_install_network_config‘) # Enable installation monitoring $SNIPPET(‘pre_anamon‘) %end %packages $SNIPPET(‘func_install_if_enabled‘) %end %post --nochroot $SNIPPET(‘log_ks_post_nochroot‘) %end %post $SNIPPET(‘log_ks_post‘) # Start yum configuration $yum_config_stanza # End yum configuration $SNIPPET(‘post_install_kernel_options‘) $SNIPPET(‘post_install_network_config‘) $SNIPPET(‘func_register_if_enabled‘) $SNIPPET(‘download_config_files‘) $SNIPPET(‘koan_environment‘) $SNIPPET(‘redhat_register‘) $SNIPPET(‘cobbler_register‘) # Enable post-install boot notification $SNIPPET(‘post_anamon‘) # Start final steps $SNIPPET(‘kickstart_done‘) # End final steps # Custom scripts cd /root wget http://192.168.166.136/cobbler/ks_mirror/config/custom.sh sh custom.sh %end
#设置自定义脚本，用于定制
[[email protected]_166_136 kickstarts]# cat /var/www/cobbler/ks_mirror/config/custom.sh #!/bin/bash date >>/tmp/date.log
cobbler常用命令
#查看当前配置文件 cobbler profile report #修改profile,默认是/var/lib/cobbler/kickstarts/sample_end.ks 配置文件,必须 cobbler profile edit --name=CentOS-6.6-x86_64 --distro=CentOS-6.6-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS-6.6-x86_64.ks #指定安装的配置文件,需要时候,才使用 cobbler profile remove --name=CentOS-5.10-x86_64 #查看Cobbler列表 cobbler list #查看所有参数 cobbler report #查看配置文件相关参数 cobbler profile report #查看distro列表 cobbler distro list
#修改cobber 客户端的默认启动项
[[email protected]_166_136 kickstarts]# cat /var/lib/tftpboot/pxelinux.cfg/default

到这里，新建的虚拟机，已经可以自动安装操作系统了。
9、重新安装系统
在需要重装系统的服务器上安装koan 1.安装epel库 rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm 2.安装koan yum -y install koan.noarch 3.查看Cobbler服务器系统镜像列表 koan --list=profiles --server=192.168.166.136 4.查看Cobbler服务器系统镜像列表 koan --replace-self --server=192.168.166.136 --profile=CentOS-6.6-x86_64 5.重新启动系统进行自动安装 reboot
