cobbler配置
借鉴了网上好多文章,但是因为是去年做的cobbler,忘记是哪些地址,故暂未附上,见谅。

设置源
采用网易的源和EPEL的源
http://mirror.bjtu.edu.cn/fedora-epel/6/i386/repoview/epel-release.html
(根据版本号下载)
yum -y install wget vim-enhanced
mv /bin/vi /bin/vi.save
ln -s /usr/bin/vim /bin/vi
cd /etc/yum.repos.d/
mkdir backup
mv *.repo ./backup
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
rpm -ivh http://mirrors.ustc.edu.cn/fedora/epel/6/i386/epel-release-6-7.noarch.rpm
yum list
设置主机名
关闭iptables,ip6tables,selinux
如果希望cobbler可以管理dhcp,dns,需要把dns和dhcp都安装在同一台服务器上。如果你不管理dns,可以不需要安装bind.
yum -y install cman tftp-server dhcp cobbler cobbler-web bind pykickstart xinetd httpd rsync xinetd python-ctypes debmirror
安装debmirror
需要用debmirror来下载ubuntu 12.04的源,做本地源.目前debmirrors, 只能使用rpm包安装,
yum -y install debmirror
配置Cobbler
vim /etc/cobbler/settings #Cobbler主配置文件
cp -p /etc/cobbler/settings /etc/cobbler/settings.bak
sed -i ‘s/manage_dhcp: 0/manage_dhcp: 1/g‘ /etc/cobbler/settings
sed -i ‘s/manage_rsync: 0/manage_rsync: 1/g‘ /etc/cobbler/settings
1:tftp服务和rsync服务
sed -i ‘/disable/c\\tdisable\t\t\t= no‘ /etc/xinetd.d/tftp
sed -i -e ‘s/\=\ yes/\=\ no/g‘ /etc/xinetd.d/rsync
service xinetd restart
2: web可以登陆
cp -p /etc/cobbler/modules.conf /etc/cobbler/modules.conf.bak
sed -i ‘s/authn_denyall/authn_configfile/g‘ /etc/cobbler/modules.conf
3: 设置cobbler web登陆,用户登陆密码
htdigest /etc/cobbler/users.digest "Cobbler" cobbler
4: 设置cobbler登陆服务器地址
sed -i ‘s/server: 127.0.0.1/server: 192.168.209.111/g‘ /etc/cobbler/settings
5:ks脚本关闭pxe,这样就不会重复安装
sed -i ‘s/pxe_just_once: 0/pxe_just_once: 1/g‘ /etc/cobbler/settings
6:TFTP服务器 IP地址
sed -i ‘s/next_server: 127.0.0.1/next_server: 192.168.209.111/g‘ /etc/cobbler/settings
7:cobbler管理rsync
sed -i ‘s/manage_rsync: 0/manage_rsync: 1/g‘ /etc/cobbler/settings
8:cobbler管理dhcp
sed -i ‘s/manage_dhcp: 0/manage_dhcp: 1/g‘ /etc/cobbler/settings
9:cobbler管理dns (可选)
sed -i ‘s/manage_dns: 0/manage_dns: 1/g‘ /etc/cobbler/settings
设置root默认密码
这个设置只针对centos有效。我默认的root密码是:fengyun299
# openssl passwd -1 -salt ‘random-phrase-here‘ ‘fengyun299‘
$1$random-p$99lAzJZEl9uunSaThe9oM0
修改 /etc/cobbler/settings
#default_password_crypted: "$1$mF86/UHC$WvcIcX2t6crBz2onWxyac."
default_password_crypted: "$1$random-p$SBOoxFrHGWHpvzS8BeGQ5/"
11: 启动相关服务
dhcp服务由于没有设置,所以无法启动。后面我们会对dhcp进行设置。另外启动named的服务时候,需要等待1,2分钟,生成一个key。
chkconfig httpd on
chkconfig cobblerd on
chkconfig named on
chkconfig dhcpd on
/etc/init.d/httpd restart
/etc/init.d/cobblerd restart
/etc/init.d/named restart
12:设置debmirror
sed -i -e ‘s|@dists=.*|#@dists=|‘ /etc/debmirror.conf
sed -i -e ‘s|@arches=.*|#@arches=|‘ /etc/debmirror.conf
13:启动菜单
cobbler get-loaders
检查cobbler
cobbler提供一个工具,检查你的设置。看到提示,就表示全部工作都已经完成。
对cobbler所有修改,需要
cobbler sync
检查
# cobbler check
No configuration problems found. All systems go.
四:web登陆
https://192.168.209.111/cobbler_web/distro/list user:cobbler 密码就是上面设置的。
cobbler的使用,主要是集中在上面几个菜单里。这里简单解析一下。
Distros:这个其实就是发行版,类似Centos,ubuntu,suse。centos6.2和centos6.3,是不同的distros。假设我们导入一个centos6.3的iso,就是增加了一个Distros
Profiles:针对Distros的设置,一个distros,可以保护多个profiles,包括不同的kickstart文件。源的设置,都是在这里设置。
Systems:针对是每个节点,这里可以指定节点的ip地址,dns name,还有就是ipmi的用户名和密码,实现远程开机,关机。这是一个重点,日后对机器的操作,全部在sytem的菜单里操作。system里,会指定节点使用哪个profile。
Repos:这个主要是针对Redhat和Centos有效,可以管理源,并且这些源,可以在profile里添加。比较方便。需要注意的是,对于ubuntu的源,只能在kickstart 脚本里指定。
Images:这个我没用到,看说明主要是针对不能pxe的机器,采用iso启动。
Kicsstart Templates:这是核心,cobbler内置了几个ks文件,你如果导入一个centos,系统会默认关联一个ks文件,你不需要做任何设置,就可以把os自动装完。对于ubuntu,我们就需要单独创建一个preseed文件,这些文件可以通过web管理和修改。非常方便。
Snippets:这是cobbler的精华。一些常用的设置,写成一个模块,让ks文件调用。这样更加灵活。例如centos的网络固定IP地址的设置,就是通过这里实现。

4.6 导入系统镜像
4.6.1 上传ISO镜像至服务器
注意下载的ISO文件要核对文件的md5值,确保数据完整性
[root@hxinstall x86_64]# md5sum CentOS-5.8-x86_64-bin-DVD-1of2.iso
8a3bf0030f192022943f83fe6b2cf373 CentOS-5.8-x86_64-bin-DVD-1of2.iso
4.6.2 创建ISO目录
mkdir -p /var/iso/Linux/Centos/x86_64/
mkdir -p /var/os/Linux/Centos/x86_64/Centos5.8/dvd
mkdir -p /var/os/Linux/Centos/x86_64/Centos6.3/dvd
mkdir -p /var/os/Linux/Centos/x86_64/Centos6.4/dvd
4.6.3 挂载ISO镜像

4.6.4 从DVD中导入OS数据
系统版本命名为centos5.8 架构x86_64,这时间长,耐性等待。可查看ls /var/www/cobbler/ks_mirror/centos5.8-x86_64/目录文件生成情况。

4.12 创建PXE菜单密码
增加装机安全设置菜单密码
生成hash密码
支持两种不同类型的密码:
sha1pass mypassword
或
openssl passwd -1 -salt sXiKzkus mypassword
我这里选择后者
# openssl passwd -1 -salt sXiKzkus hexun
$1$sXiKzkus$2DoZ6pfTe8rrc0Si60ecB/
编辑配置文件pxedefault,添加如下蓝色部分
vim /etc/cobbler/pxe/pxedefault.template
DEFAULT menu
PROMPT 0
MENU TITLE Cobbler | http://fedorahosted.org/cobbler
MENU MASTER PASSWD $1$sXiKzkus$2DoZ6pfTe8rrc0Si60ecB/
TIMEOUT 200
TOTALTIMEOUT 6000
ONTIMEOUT $pxe_timeout_profile
LABEL local
MENU LABEL (local)

配置pxeprofile,增加蓝色部分
vim /etc/cobbler/pxe/pxeprofile.template

MENU PASSWD
kernel $kernel_path
$menu_label
$append_line
ipappend 2
修改完毕注意检查、同步配置使其生效
cobbler check
No configuration problems found. All systems go.
cobbler sync
4.13 定制PXE菜单TITLE
编辑pxedefault文件,
vim /etc/cobbler/pxe/pxedefault.template
MENU TITLE Cobbler | http://fedorahosted.org/cobbler
将原文上面的内容根据自定义进行修改

修改完毕执行如下两条命令
cobbler check
cobbler sync
4.14 添加指定客户机系统配置到Cobbler
4.14.1 指定一个网段使用特定的装机配置
cobbler system add --name=networktest --ip-address=192.168.209.0 --subnet=255.255.255.0 --profile=CentOS6.0-x86_64
4.14.2 添加一个指定服务器的装机配置
指定服务器就是绑定它的mac地址,并设置好ip、dns、hostname
定义系统
cobbler system add --name=kingserver230 --hostname=kingserver230 --mac=00:50:56:2E:96:D2 --interface=eth0 --ip-address=192.168.209.230 --subnet=255.255.255.0 --gateway=192.168.209.1 --static=1 --profile=CentOS6.0-x86_64
查看定义的系统列表
[root@kingserver110 kickstarts]# cobbler system list
kingserver220
kingserver230
networktest
更多参数见cobbler system add --help
五、Cobbler Web管理
Cobbler web界面是一个很好的前端,非常容易管理Cobbler
可以添加和删除 system distro profile
可以查看、编辑distros, profiles, subprofiles, systems, repos 、 kickstart文件
5.1 安装cobbler_web
yum -y install cobbler-web
5.2 设置用户名密码
为已存在的用户cobbler重置密码
htdigest /etc/cobbler/users.digest "Cobbler" cobbler
添加新用户
htdigest /etc/cobbler/users.digest "Cobbler" your_newname
5.3 配置cobbler web可以登录
sed -i ‘s/authn_denyall/authn_configfile/g‘ /etc/cobbler/modules.conf
5.4 重启Cobbler与http
/etc/init.d/cobblerd restart
/etc/init.d/httpd restart
三、Cobbler 常用命令汇总
1.导入镜像文件
命令:cobbler import --path=镜像路径 -- name=安装引导名 --arch=32位或64位
参数:
· path 是镜像所挂载的目录
· name 是导入到cobbler里面显示的名字
· arch 是32位系统还是64位系统
2.导入kickstart文件
命令:cobbler profile add --name=list名 --distro=镜像 --kickstart=路径
参数:
· name是表示添加的ks 的名字,用cobbler report可以看到这个名字
· distro 是用哪个镜像,list的distros里面选择一个,需要版本相对应
· kickstart 是具体的 ks 文件路径
3.同步DHCP、HTTPD
命令:cobbler sync
注,每次修改完dhcp.template之类的配置文件需要执行一次使其生效。
4.查看Cobbler列表
命令:cobbler list
注,列出Cobbler所有的元素。
5.删除相关列表
命令:cobbler distro/profile remove --name=要删除的引导文件名
· 删除指定 distro , 也就是镜像
· 删除指定的 profile 文件,也就是 ks
四、Cobbler 各种目录说明(注,这里只介绍重点的文件或目录 )

7、 RPM 仓库管理 (根据需要自己决定吧)
相关阅读:https://fedorahosted.org/cobbler/wiki/ManageYumRepos
我们可以为cobbler 添加 RPM 仓库:
cobbler repo add --name= RHEL5.6-x86-64 --mirror= http://mirrors.163.com/centos/5/os/x86_64/
cobbler repo add --name= EPEL5.-x86-64 --mirror= http://mirrors.ustc.edu.cn/fedora/epel/5/x86_64/
同步仓库到本地:
cobbler reposync
也可以通过设置--mirror-locally=0 不下载到本地,而通过 kickstart server 去仓库下载 rpm 包。
添加计划任务,每天凌晨两点进行一次同步:
crontab -e
0 2 * * * cobbler reposync --tries=3 --no-fail
8、设置 profile 和 system (这个功能比较牛 P。需要深入研究哈)
profile可以理解为按角色进行分类。
cobbler profile add --name=webserver --distro=CentOS-5-i386 --repos=EPEL-5-i386 --kickstart=/var/lib/cobbler/kickstarts/webserver.ks
system是对待安装机器做具体设置,如设置主机名、 IP 地址、 hostname 等,这些设置根据 MAC 应用到具体机器上。
# cobbler system add --name=webserver1 --ip=192.168.0.110 --mac=00:0C:29:77:89:c7 --profile=webserver --kickstart=/var/lib/cobbler/kickstarts/webserver.ks --static=1
# cobbler system edit --name=webserver1 --dns-name=webserver1.grid.house.sina.com.cn --hostname=webserver1.grid.house.sina.com.cn
cobbler system edit --name=webserver1 --gateway=192.168.0.1 --subnet=255.255.255.0
cobbler system edit --name=webserver1 --interface=eth1 --static=0
可以通过访问http://192.168.0.2/cblr/svc/op/ks/system/webserver1 来查看真正的 kickstart 配置。
12、 Cobbler 命令说明
cobbler check - 核对当前设置是否有问题
cobbler list - 列出所有的 cobbler 元素
cobbler report - 详细的列出个元素
cobbler sync - 同步配置到 dhcp/pxe 和数据目录
cobbler reposync - 同步 yum 仓库
13、 Cobbler 配置文件说明
Cobbler配置文件存放在 /etc/cobbler 下。 /etc/cobbler/settings 为主配置文件;在 /etc/cobbler 下你还能看到 dhcp 、 dns 、 pxe 、 dnsmasq 的模板配置文件; /etc/cobbler/users.digest 为用于 web 访问的用户名密码配置文件; /etc/cobbler/modules.conf 为模块配置文件;/etc/cobbler/users.conf 为 Cobbler WebUI/Web service 授权配置文件。
Repo数据目录 /var/www/cobbler
导入的发行版,repos 镜像和 kickstart 文件都放置在 /var/www/cobbler 目录下。确保 /var 目录有足够的空间来存储这些文件。
images/ - 存储所有导入发行版的 Kernel 和 initrd 镜像用于远程网络启动
ks_mirror/ - 存储导入的发行版
repo_mirror/ - yum repos存储目录
/var/log/cobbler用于存放日志文件 /var/log/cobbler/cobbler.log
Cobbler数据目录 /var/lib/cobbler ,此目录存储和 Cobbler profiles 、 systems 、 distros 相关的配置。
configs/ - 此目录用于存储 distros 、 repos 、 systems 和 profiles 相关信息
backup/ - 备份目录
snippets/ - 用于放置一些可以在 kickstarts 导入的脚本小片段
triggers/ - 此目录用来放置一些可执行脚本
kickstarts/ - 此目录用来放置 kickstart 模板文件
与Puppet 整合进行配置管理: 这个功能后续在研究吧。先写到这里。感谢你的支持。
