cobbler学习(一)RPM-cobbler自动装机
一：Cobbler的安装
安装epel源：
[root@kaibin ~]# rpm -ivh http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm Retrieving http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm warning: /var/tmp/rpm-tmp.HDIstu: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEY Preparing... ########################################### [100%] 1:epel-release ########################################### [100%]
安装cobbler及其他服务
yum-y install cobbler httpd rsync tftp-server xinetd dhcp python-ctypes cman pykickstart
2.配置cobbler
2.1配置cobbler主配置文件
vim /etc/cobbler/settings #cobbler主配置文件 manage_dhcp: 1 #启用cobbler dhcp功能 manage_rsync: 1 #启用cobbler rsync功能 next_server: 192.168.40.145 #dhcp服务地址 server: 192.168.40.145 #cobbler 服务地址 default_kickstart:/var/lib/cobbler/kickstarts/default.ks #默认ks文件
2.1 检查，关闭selinuxiptable
/etc/init.d/iptables stop chkconfig iptables off setenforce 0
2.2 配置tftp ,rsync
vim /etc/xinetd.d/tftp vim /etc/xinetd.d/rsync disable= no
2.3 启用wsgi模块
vim /etc/httpd/conf.d/wsgi.conf LoadModulewsgi_module modules/mod_wsgi.so
2.4 生成Cobbler安装系统初始密码
openssl passwd -1 -salt 'zuoliao' 'mima' $1$zuoliao$ucZsjnNnYeC1ddo9O19ei0 加入Cobbler设置 vim /etc/cobbler/settings default_password_crypted:"$1$zuoliao$ucZsjnNnYeC1ddo9O19ei0"
2.5 配置HDCP
vim /etc/cobbler/dhcp.template
subnet 192.168.40.0 netmask 255.255.255.0{
option routers 192.168.40.145;
option domain-name-servers 219.141.136.10;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.40.100 192.168.40.150; #分配的IP地址
default-lease-time 600; #默认租约时间
max-lease-time 1200; #最大租约时间
next-server $next_server;
class "pxeclients" {
match if substring (optionvendor-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";
}
}
}
2.6 设置相关服务启动及开机自启动
/etc/init.d/httpd start /etc/init.d/xinetd start /etc/init.d/cobblerd start chkconfig httpd on chkconfig xinetd on chkconfig cobblerd on
2.7 下载引导操作系统软件
[root@kaibin ~]# /etc/init.d/cobblerd restart [root@kaibin ~]# cobbler get-loaders
2.8 配置debmirror
yum -y install debmirror vim /etc/debmirror.conf #@dists="sid"; #@arches="i386";
2.9 检查Cobbler 配置
cobbler check
根据提示解决错误
2.91同步设置
cobbler sync
3.导入系统镜像
mkdir /var/os/Linux/Centos/x86_64/Centos6.4/dvd mount -o loop /media/rhel-server-6.4-x86_64-dvd.iso /var/os/Linux/Centos/x86_64/Centos6.4/dvd cobbler import --path=/var/os/Linux/Centos/x86_64/Centos6.4/dvd --name=centos6.5 --arch=x86_64
删除导入的系统镜像:
[root@kaibin ~]# cobbler profile find --distro=centos6.5-x86_64 #查看配置文件是否存在 centos6.5-x86_64
[root@kaibin ~]# cobbler profile remove --name=centos6.5-x86_64 #删除配置文件
[root@kaibin ~]# cobbler distro remove --name=centos6.5-x86_64 #删除distro
[root@kaibin ~]# cobbler profile find --distro=centos6.5-x86_64 #再查看配置已无
列出导入后的配置
cobblerlist
列出详细信息
cobbler report
4.创建PXE菜单密码
openssl passwd -1 -salt 111 kaibin.com $1$111$NguSK02gcD9XFcrcw4Hww. vim /etc/cobbler/pxe/pxedefault.template MENU TITLE co-mall | Auto Install System #设置装系统标题 MENU MASTER PASSWD $1$111$NguSK02gcD9XFcrcw4Hww. #设置密码
[root@kaibin ~]# vim /etc/cobbler/pxe/pxeprofile.template LABEL $profile_name MENU PASSWD kernel $kernel_path $menu_label $append_line ipappend 2
重新加载配置文件 [root@kaibin ~]# cobbler check [root@kaibin ~]# cobbler sync
5. Cobbler web管理
5.1 yum安装cobbler_web
yum -y install cobbler-web htdigest /etc/cobbler/users.digest "yuanbinbin" cobbler #创建新用户
5.2 重启cobbler与http
cobbler-web默认管理 cobbler:cobbler
URL: http://192.168.3.110/cobbler_web
6. 添加指定客户机系统配置到Cobbler
1. 指定一个网段使用特定的装机配置
cobbler system add --name=test_000 --ip=192.168.1.0/24 --profile=Centos-5.9-x86_64
2. 添加一个指定服务器的装机配置
指定服务器的mac地址，并设置好主机名、IP地址等信息，需要提示知道服务器MAC地址，根据MAC应用到具体机器上。
还可以指定ks参数。--kickstart=/var/lib/cobbler/kickstarts/webserver.ks
[root@kaibin ~]# cobbler system add --name=test_001 --profile=centos6.5-system-x86_64 --mac=00:0C:29:44:C0:96 --interface=eth0 \ --ip-address=192.168.3.140 --gateway=192.168.3.1 --dns-name=8.8.8.8 --hostname=kaibin.test3.com \ --netboot-enabled=Y --subnet=255.255.255.0 --static=1 --kickstart=/var/lib/cobbler/kickstarts/sample_end.ks
3. 修改system配置
机器IP地址变更为192.168.10.110
cobbler system add --name=test_001 --ip=192.168.1.110
变更system配置名称
cobbler system rename --name=test001 --newname=abc
4. 删除system配置
需要删除的profile名称为test_001
cobbler system remove --name=test_001
5. 查看定义的系统列表
cobbler system list
test_001
