cobbler实现

系统：centos7.10 1810
cobbler 基于epel源，先打开epel源，使用1804版本的epel，较新版本会有问题（本次实验进行的时候）

1、安装cobbler

yum install cobbler 安装cobbler时会自动安装tftp,http这两个服务以及相关的其他工具包，但不会安装dhcp服务，实现cobbler还需要dhcp服务，手动安装
yum install dhcp

2、开启服务

开启除了dhcp外的所有服务并设置为开机启动(实际工作中)。tftp、http、cobbler
systemctl start tftp httpd cobblerd
systemctl enable tftp httpd dhcpd cobblerd
使用cobbler check命令检查cobbler的相关配置，并根据提示逐个修改为正确配置

3、修改配置文件

修改/etc/cobbler/settings进行配置

第101行“default_password_crypted:”为cobbler密码，默认为cobbler(此密码为系统密码),用MD5加密,将新密码加密后覆盖原来的加密密码
第242行 “manage_dhcp: 0” 将0改为1 自动配置dhcp
第272行“next_server: 127.0.0.1”为tftp服务器地址，修改为正确的tftp服务器地址。可以是本机地址，也可以是同网络中的tftp服务器地址
第384行“server: 127.0.0.1”为cobbler服务器的地址，修改为本机地址

运行cobbler get-loader自动安装cobbler需要的文件，如pxelinux,syslinux等

[root@CentOS7 yum.repos.d]#cobbler get-loaders

修改完成后运行cobbler sync更新配置

[root@CentOS7 yum.repos.d]#cobbler sync

*** TASK COMPLETE ***

重启cobbler服务，再次运行cobbler check检查，如提示如下三行，可以不用管了

[root@CentOS7 yum.repos.d]#cobbler check
The following are potential configuration items that you may want to fix:

1 : enable and start rsyncd.service with systemctl
2 : debmirror package is not installed, it will be required to manage debian deployments and repositories
3 : 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.

运行vim /etc/cobbler/dhcp.template 编辑DHCP模板文件，设置DHCP服务

根据实际情况设置图片中的几项就可以
运行 cobbler sync 更新配置，因为前面将配置文件第242行 “manage_dhcp: 0” 的0改为1，所以会自动更新dhcp服务的配置文件

4、拷贝文件到相应目录

将安装源文件拷贝到相应的目录(/var/www/cobbler/ks_mirror/)中。实验中用的光盘iso文件，已将光盘挂载到/mnt目录下
运行cobbler improt --path=/mnt --name=Centos-7.6 --arch=x86_64(CPU架构) 开始自动拷贝文件，时间长短看拷贝文件的大小
拷贝完成后运行下面的命令可查看不同的信息：

cobbler profile list 查看启动菜单项(ks文件和源文件的关联)      
cobbler distro list 查看安装源文件    

关联自定义ks文件，修改ks文件中的设置

将自定义的应答文件拷贝到/var/lib/cobbler/kickstarts目录下，并将文件权限修改为644

5、关联应答文件

cobbler profile add --name=Centos-7.6-x86_64_mini --distro=Centos7.6_mini-x86_64 --kickstart=/var/lib/cobbler/kickstarts/ks7_mini.cfg
--name为显示在启动菜单中的名字
--distro为安装源文件名字(使用cobbler distro list查看)
--kickstart为与源文件关联的ks文件路径
删除不符合要求的菜单
cobbler profile remove --name=Centos7.6_mini-x86_64
到此已经完成cobbler的设置，测试用一台机器通过网卡启动找到服务器，选择想要安装的系统
如果有什么服务不能用，重启后测试

cobbler web 实现

cobbler 可以通过web界面设置
yum install cobbler-web
重新启动HTTPD服务
systemctl restart httpd
通过浏览器访问：https://ip/cobbler_web 来管理cobbler服务
用户名cobbler,默认密码为cobbler

使用authn_configfiel模块认证cobbler_web用户(默认选项)

用户名密码保存在/etc/cobbler/users.digest 中通过cat命令可以查看
按照下面格式添用户名：其中cobbler1为新添加的用户名，输入两次新密码

[root@CentOS7 ~]#htdigest -c /etc/cobbler/users.digest Cobbler cobbler1
Adding user cobbler1 in realm Cobbler
New password: 
Re-type new password: 

参数 -c 表示删除已有的第一个用户并新建cobbler1 用于第一次设置用户时使用,后续添加可以不用“-c”

使用authm_pam模块认证cobbler_web用户

vim /etc/cobbler/modules.conf
修改23行
将module = authn_configfile 修改为moudle = authn_pam
创建cobbler 用户: useradd cobbler2 并设置密码 echo xxx | passwd --stdin cobbler2
可以将cobbler2用户的shell 设置为/sbin/nologin
vim /etc/cobbler/users.conf
修改admin = "" 为admin = "cobbler2"
重启cobbler服务，用cobbler2访问web页面

两种方式在用户不能同时使用，一种生效，别一种就无法登录web页面

cobbler实现，cobbler_web管理
