第1章 cobbler安装部署
1.1 Cobbler介绍
Cobbler是一个Linux服务器安装的服务，可以通过网络启动(PXE)的方式来快速安装、重装物理服务器和虚拟机，同时还可以管理DHCP，DNS等。
Cobbler可以使用命令行方式管理，也提供了基于Web的界面管理工具(cobbler-web)，还提供了API接口，可以方便二次开发使用。
Cobbler是较早前的kickstart的升级版，优点是比较容易配置，还自带web界面比较易于管理。
Cobbler内置了一个轻量级配置管理系统，但它也支持和其它配置管理系统集成，如Puppet，暂时不支持SaltStack。
提示：cobbler官网：http://cobbler.github.io/
1.1.1 Cobbler集成的服务
- PXE服务支持
- DHCP服务管理
- DNS服务管理(可选bind,dnsmasq)
- 电源管理
- Kickstart服务支持
- YUM仓库管理
- TFTP(PXE启动时需要)
- Apache(提供kickstart的安装源，并提供定制化的kickstart配置)
1.2 系统环境准备
同kickstart系统环境准备。
1.3 安装cobbler
1.3.1 安装cobbler-web依赖源
[[email protected] ~]# yum localinstall -y http://ftp.linux.ncsu.edu/pub/epel/6/x86_64/Django14-1.4.21-1.el6.noarch.rpm # 或者（如果外网环境不好可以使用内网yum源） [[email protected] ~]# yum localinstall -y http://10.0.0.90/epel/6/x86_64/Django14-1.4.21-1.el6.noarch.rpm
1.3.2 安装cobbler相关软件
[[email protected] ~]# yum install -y cobbler cobbler-web dhcp tftp-server pykickstart httpd
1.3.3 cobbler安装文件说明
[[email protected] ~]# rpm -ql cobbler # 查看安装的文件，下面列出部分。 /etc/cobbler # 配置文件目录 /etc/cobbler/settings # cobbler主配置文件，这个文件是YAML格式，Cobbler是python写的程序。 /etc/cobbler/dhcp.template # DHCP服务的配置模板 /etc/cobbler/tftpd.template # tftp服务的配置模板 /etc/cobbler/rsync.template # rsync服务的配置模板 /etc/cobbler/iso # iso模板配置文件目录 /etc/cobbler/pxe # pxe模板文件目录 /etc/cobbler/power # 电源的配置文件目录 /etc/cobbler/users.conf # Web服务授权配置文件 /etc/cobbler/users.digest # 用于web访问的用户名密码配置文件 /etc/cobbler/dnsmasq.template # DNS服务的配置模板 /etc/cobbler/modules.conf # Cobbler模块配置文件 /var/lib/cobbler # Cobbler数据目录 /var/lib/cobbler/config # 配置文件 /var/lib/cobbler/kickstarts # 默认存放kickstart文件 /var/lib/cobbler/loaders # 存放的各种引导程序 /var/www/cobbler # 系统安装镜像目录 /var/www/cobbler/ks_mirror # 导入的系统镜像列表 /var/www/cobbler/images # 导入的系统镜像启动文件 /var/www/cobbler/repo_mirror # yum源存储目录 /var/log/cobbler # 日志目录 /var/log/cobbler/install.log # 客户端系统安装日志 /var/log/cobbler/cobbler.log # cobbler日志
1.3.4 启动服务
[[email protected] ~]# service httpd restart # 重启apache服务 [[email protected] ~]# service cobblerd start # 启动cobbler服务
1.4 下载cobbler启动文件
[[email protected] ~]# cobbler get-loaders # 或预先下载相关文件后上传到服务器 [[email protected] ~]# wget http://192.168.12.200/cobbler/cobbler_load.tar.gz [[email protected] ~]# tar xfP cobbler_load.tar.gz
1.5 配置DHCP
修改cobbler的dhcp模版，不要直接修改dhcp本身的配置文件，因为cobbler会覆盖。
[[email protected] ~]# vim /etc/cobbler/dhcp.template 21 subnet 10.0.0.0 netmask 255.255.255.0 { 22 option routers 10.0.0.254; 23 option domain-name-servers 10.0.0.254; 24 option subnet-mask 255.255.255.0; 25 range dynamic-bootp 10.0.0.150 10.0.0.200; # 或 [[email protected] ~]# cp /etc/cobbler/dhcp.template{,.bak} # 下面的命令只可执行一次，不可多次执行，否则配置文件会被损坏 [[email protected] ~]# sed -i 's#192.168.1#172.16.1#g;22d;23d' /etc/cobbler/dhcp.template
注意：刚安装完dhcp时无法启动服务，因为dhcp配置文件未编写，需要待cobbler同步后方可启动dhcp服务。
1.6 配置Cobbler
1.6.1 cobbler自查配置
# 检查Cobbler的配置，如果看不到下面的结果，再次执行/etc/init.d/cobblerd restart [[email protected] ~]# cobbler check The following are potential configuration items that you may want to fix: 1 : service dhcpd is not running 2 : change 'disable' to 'no' in /etc/xinetd.d/tftp 3 : 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. 4 : 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. 5 : change 'disable' to 'no' in /etc/xinetd.d/rsync 6 : file /etc/xinetd.d/rsync does not exist 7 : debmirror package is not installed, it will be required to manage debian deployments and repositories 8 : 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 9 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them Restart cobblerd and then run 'cobbler sync' to apply changes.
1.6.2 解决第1个问题
此时只配置了DHCP模板，但DHCP配置文件还没有更改，所以无法直接启动DHCP服务，只要之后cobbler同步一次即可解决问题：
[[email protected] ~]# cobbler sync
1.6.3 解决第2个问题
[[email protected] ~]# vim /etc/xinetd.d/tftp # default: off # description: The tftp server serves files using the trivial file transfer \ # protocol. The tftp protocol is often used to boot diskless \ # workstations, download configuration files to network-aware printers, \ # and to start the installation process for some operating systems. service tftp { socket_type = dgram protocol = udp wait = yes user = root server = /usr/sbin/in.tftpd server_args = -s /var/lib/tftpboot disable = no # 将yes改为no per_source = 11 cps = 100 2 flags = IPv4 }
1.6.4 解决第3、4、8个问题
[[email protected] ~]# cp /etc/cobbler/settings{,.bak} # 备份配置文件 # 生成加密密码，random-phrase-here为干扰码，可以自行设定。 [[email protected] ~]# openssl passwd -1 -salt 'oldboy' '123456' $1$oldboy$Npg9Pt9k98Mlg0ZeqHAuN1 [[email protected] ~]# vim /etc/cobbler/settings # 设置新装系统的默认root密码123456。 101 default_password_crypted: "$1$oldboy$Npg9Pt9k98Mlg0ZeqHAuN1" # 用Cobbler管理DHCP 242 manage_dhcp: 1 # 如果用Cobbler管理DHCP，修改本项，作用参看kickstart。 272 next_server: 10.0.0.61 # 防止循环装系统，适用于服务器第一启动项是PXE启动。 292 pxe_just_once: 1 # Cobbler服务器的IP 384 server: 10.0.0.61
1.6.5 解决第5个问题
[[email protected] ~]# vim /etc/xinetd.d/rsync # default: off # description: The rsync server is a good addition to an ftp server, as it \ # allows crc checksumming etc. service rsync { disable = no # 将yes改为no flags = IPv6 socket_type = stream wait = no user = root server = /usr/bin/rsync server_args = --daemon log_on_failure += USERID } [[email protected] ~]# service xinetd restart [[email protected] ~]# service cobblerd restart
1.6.6 批量解决上述问题
sed -i 's/server: 127.0.0.1/server: 172.16.1.101/' /etc/cobbler/settings sed -i 's/next_server: 127.0.0.1/next_server: 172.16.1.101/' /etc/cobbler/settings sed -i 's/manage_dhcp: 0/manage_dhcp: 1/' /etc/cobbler/settings sed -i 's/pxe_just_once: 0/pxe_just_once: 1/' /etc/cobbler/settings sed -ri "/default_password_crypted/s#(.*: ).*#\1\"`openssl passwd -1 -salt 'oldboy' '123456'`\"#" /etc/cobbler/settings sed -i 's#yes#no#' /etc/xinetd.d/rsync sed -i 's#yes#no#' /etc/xinetd.d/tftp
1.6.7 查看更改后结果
[[email protected] loaders]# cobbler check The following are potential configuration items that you may want to fix: 1 : file /etc/xinetd.d/rsync does not exist # 程序开发的逻辑错误，即程序bug 2 : debmirror package is not installed, it will be required to manage debian deployments and repositories # 和debian系统相关，不需要 3 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them # fence电源管理设备相关，不需要 Restart cobblerd and then run 'cobbler sync' to apply changes.
1.7 同步cobbler配置
同步最新cobbler配置，它会根据配置自动修改dhcp等服务。
[[email protected] ~]# cobbler sync # 同步所有配置
1.8 设置相关服务开机启动
启动相关服务并设置开机启动(可选) 与第二种方法二选一
[[email protected] ~]# chkconfig httpd on [[email protected] ~]# chkconfig xinetd on [[email protected] ~]# chkconfig cobblerd on [[email protected] ~]# chkconfig dhcpd on [[email protected] ~]# service httpd restart [[email protected] ~]# service xinetd restart [[email protected] ~]# service cobblerd restart [[email protected] ~]# service dhcpd restart
1.8.1 编写Cobbler相关服务启动脚本(可选)
[[email protected] ~]# vim /etc/init.d/cobbler #!/bin/bash # chkconfig: 345 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 ;; esac [[email protected] ~]# chmod +x /etc/init.d/cobbler [[email protected] ~]# chkconfig cobbler on

1.10 CentOS6.x自动部署配置
1.10.1 导入镜像
[[email protected] ~]# mount /dev/cdrom /mnt [[email protected] ~]# cobbler import --path=/mnt/ --name=CentOS6.9-x86_64 --arch=x86_64
- 命令说明：
- --path 镜像路径
- --name 为安装源定义一个名字
- --arch 指定安装源是32位、64位、ia64, 目前支持的选项有: x86│x86_64│ia64
- 安装源的唯一标示就是根据name参数来定义，本例导入成功后，安装源的唯一标示就是：9-x86_64，如果重复，系统会提示导入失败。
[[email protected] ~]# cobbler distro list # 查看镜像列表 CentOS6.9-x86_64 # 镜像存放目录，cobbler会将镜像中的所有安装文件拷贝到本地一份，放在/var/www/cobbler/ks_mirror下的CentOS6.9-x86_64目录下。因此/var/www/cobbler目录必须具有足够容纳安装文件的空间。 [[email protected] ~]# cd /var/www/cobbler/ks_mirror/ [[email protected] ks_mirror]# ls CentOS6.9-x86_64 config [[email protected] ks_mirror]# ls CentOS6.9-x86_64/ CentOS_BuildTag isolinux RPM-GPG-KEY-CentOS-Debug-6 EFI Packages RPM-GPG-KEY-CentOS-Security-6 EULA RELEASE-NOTES-en-US.html RPM-GPG-KEY-CentOS-Testing-6 GPL repodata TRANS.TBL images RPM-GPG-KEY-CentOS-6

1.11.13重命名CentOS7.2-x86_64的profile文件
1.11.4 制作新的GUI profile文件
1.12 自动化安装系统
如上图：此时如果有多个系统则会显示在此处，手动选择需要安装的系统即可，或直接在ks.cfg文件中定义要安装的系统。
1.13 查看安装结果
1.14 定制化安装
1.14.1 区分物理机的方式
区分一台服务器的最简单的方法就是物理MAC地址，物理服务器的MAC地址书写在服务器上的标签，虚拟机的MAC查看方式：
1.14.2 进行定制化安装
[[email protected] ~]# cobbler system add --name=Leon --mac=00:50:56:2C:76:77 --profile=CentOS7.4-x86_64 --ip-address=10.0.0.111 --subnet=255.255.255.0 --gateway=10.0.0.254 --interface=eth0 --static=1 --hostname=Test --name-servers="223.5.5.5 223.6.6.6" # --name 自定义但不能重复 [[email protected] ~]# cobbler system list # 查看定义的列表 Leon [[email protected] ~]# cobbler sync
此时开机安装会为MAC地址为00:50:56:2C:76:77的物理机自动安装CentOS7.4，不需要自己再选择要安装的系统了。
