1、Cobbler安裝
1.1 基礎環境準備
查看當前系統版本
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
關閉selinux防火牆
[root@localhost ~]# vim /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
[root@localhost ~]# setenforce 0
關閉ebtables firewalld 防火牆
[root@localhost ~]# systemctl stop ebtables firewalld
[root@localhost ~]# systemctl disable ebtables firewalld
安裝base epel源
[root@localhost ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@localhost ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
2. 安裝cobbler服務
2.1 安裝cobbler及各個組件
[root@localhost ~]# yum -y install cobbler cobbler-web pykickstart httpd dhcp tftp rsync xinetd
3. Cobbler安裝配置文件概述
/etc/cobbler #配置文件目錄
/etc/cobbler/sttings #cobbler主配置文件
/etc/cobbler/dhcp.template #DHCP服務的配置模版
/etc/cobbler/tftpd.template #TFTP服務的配置模版
/etc/cobbler/rsync.template #Rsync服務的配置模版
/var/lib/cobbler/kickstarts #默認存放ksickstarts文件
/var/lib/cobbler/loaders #存放的各種引導程序
/var/www/cobbler #系統安裝鏡像目錄
/var/www/cobbler/images #導入的系統鏡像列表
/var/www/cobbler/ks_mirror #導入的系統鏡像啓動文件
/var/www/cobbler/repo_mirror #yum源存儲目錄
/var/log/cobbler #日誌目錄
/var/log/cobbler/install.log #客戶端系統安裝日誌
/var/log/cobbler/cobbler.log #cobbler日誌
4. 啓動httpd服務以及cobbler
[root@localhost ~]# systemctl start httpd cobblerd
[root@localhost ~]# systemctl enable httpd cobblerd
5. 執行cobbler檢測
[root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:
1 : 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.
2 : 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.
3 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment: https://github.com/cobbler/cobbler/wiki/Selinux
4 : change 'disable' to 'no' in /etc/xinetd.d/tftp
[root@localhost ~]# systemctl restart xinetd.service
5 : Some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely. Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements.
6 : enable and start rsyncd.service with systemctl
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 cmanor fence-agents to use them
Restart cobblerd and then run 'cobbler sync' to apply changes.
6. 重啓cobbler服務，並cobbler sync執行同步
[root@localhost ~]# systemctl restart cobblerd
[root@localhost ~]# cobbler sync
7. 重新檢測
[root@localhost ~]# cobbler check
No configuration problems found. All systems go. ##沒有發現配置問題。 所有系統都去了。
[root@localhost ~]#
8. 使用cobbler管理，配置DHCP服務，修改cobbler配置文件
[root@localhost ~]# vim /etc/cobbler/settings
manage_dhcp: 1
9. 配置cobbler的DHCP模版
[root@localhost ~]# vim /etc/cobbler/dhcp.template
subnet 192.168.1.0 netmask 255.255.255.0 {option routers 192.168.1.1;
option domain-name-servers 192.168.1.1;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.1.100 192.168.1.254;
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
10. 重啓一下cobbler服務
[root@localhost ~]# systemctl restart cobblerd
11. 添加管理cobbler的用戶
[root@localhost ~]# htdigest -c /etc/cobbler/users.digest Cobbler cobbler
Adding password for cobbler in realm Cobbler.
New password:
Re-type new password:
[root@localhost ~]# systemctl restart cobblerd httpd
12. 瀏覽器打開web管理界面
解決步驟：
1. SSL 的報錯日誌如下：
[root@localhost ~]# tail -f /var/log/httpd/ssl_error_log
[Tue May 28 16:54:16.665181 2019] [:error] [pid 7001] [remote 192.168.1.109:44] self._setup(name)

2. 查看cobbler的py配置文件
[root@localhost ~]# sed -n '38,41p' /usr/share/cobbler/web/settings.py
if django.VERSION[0] == 1 and django.VERSION[1] < 4:
ADMIN_MEDIA_PREFIX = '/media/'
else:
STATIC_URL = '/media/'
[root@localhost ~]# sed -n '89p' /usr/share/cobbler/web/settings.py
from django.conf.global_settings import TEMPLATE_CONTEXT_PROCESSORS
3. 初步判斷應該是pythone-django版本問題
##下載get-pip.py
