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防火墻?

[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 防火墻

[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

4. 啟動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?checkThe?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. 重啟cobbler服務，并cobbler sync執行同步

[root@localhost?~]#?systemctl?restart?cobblerd[root@localhost?~]#?cobbler?sync

7. 重新檢測

[root@localhost?~]#?cobbler?checkNo?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.templatesubnet?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. 重啟一下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?cobblerAdding?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 的報錯日志如下：

[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)[Tue?May?28?16:54:16.665190?2019]?[:error]?[pid?7001]?[remote?192.168.1.109:44]???File?"/usr/lib/python2.7/site-packages/django/conf/__init__.py",?line?41,?in?_setup[Tue?May?28?16:54:16.665205?2019]?[:error]?[pid?7001]?[remote?192.168.1.109:44]?????self._wrapped?=?Settings(settings_module)[Tue?May?28?16:54:16.665209?2019]?[:error]?[pid?7001]?[remote?192.168.1.109:44]???File?"/usr/lib/python2.7/site-packages/django/conf/__init__.py",?line?110,?in?__init__[Tue?May?28?16:54:16.665217?2019]?[:error]?[pid?7001]?[remote?192.168.1.109:44]?????mod?=?importlib.import_module(self.SETTINGS_MODULE)[Tue?May?28?16:54:16.665223?2019]?[:error]?[pid?7001]?[remote?192.168.1.109:44]???File?"/usr/lib64/python2.7/importlib/__init__.py",?line?37,?in?import_module[Tue?May?28?16:54:16.665445?2019]?[:error]?[pid?7001]?[remote?192.168.1.109:44]?????__import__(name)[Tue?May?28?16:54:16.665455?2019]?[:error]?[pid?7001]?[remote?192.168.1.109:44]???File?"/usr/share/cobbler/web/settings.py",?line?89,?in?<module>[Tue?May?28?16:54:16.665500?2019]?[:error]?[pid?7001]?[remote?192.168.1.109:44]?????from?django.conf.global_settings?import?TEMPLATE_CONTEXT_PROCESSORS[Tue?May?28?16:54:16.665516?2019]?[:error]?[pid?7001]?[remote?192.168.1.109:44]?ImportError:?cannot?import?name?TEMPLATE_CONTEXT_PROCESSORS

2. 查看cobbler的py配置文件

[root@localhost?~]#?sed?-n?'38,41p'?/usr/share/cobbler/web/settings.pyif?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.pyfrom?django.conf.global_settings?import?TEMPLATE_CONTEXT_PROCESSORS

3. 初步判斷應該是pythone-django版本問題

4. 重啟HTTP服務

[root@localhost?~]#?systemctl?restart?httpd

5. 瀏覽器界面刷新即可
