3?:?debmirror?package?is?not?installed,?it?will?be?required?to?manage?debian?deployments?and?repositories ?

解決：提示說debmirror沒安裝。如果不是安裝?debian之類的系統，此提示可以忽略，如果需要安裝， ?

安裝?debmirror ?

yum?-y?install?debmirror ?

?

編輯注釋 ?

修改?/etc/debmirror.conf?配置文件，注釋掉?@dists?和?@arches?兩行 ?

sed?-i??'s|@dists=.*|#@dists=|'??/etc/debmirror.conf ?

sed?-i??'s|@arches=.*|#@arches=|'??/etc/debmirror.conf ?

4?:?ksvalidator?was?not?found,?install?pykickstart ?

解決：安裝ksvalidator ?

?yum?install?pykickstart?-y ?

?

5?:?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 ?

解決：修改cobbler用戶的默認密碼，可以使用如下命令生成密碼，并使用生成后的密碼替換/etc/cobbler/settings中?default_password_crypted?的密碼。 ?

生成密碼命令：???

#openssl?passwd?-1?-salt?'random-phrase-here'?'[任意密碼]'????

openssl?passwd?-1?-salt?'random-phrase-here'?'hexun'?

$1$random-p$Q1IN9LaNg7yhRKJuY50fV1 ?

?

6?:?fencing?tools?were?not?found,?and?are?required?to?use?the?(optional)?power?management?features.?install?cman?or?fence-agents?to?use?them ?

?

解決:安裝cman工具用于電源管理 ?

yum??-y?install?cman ?

?

Restart?cobblerd?and?then?run?'cobbler?sync'?to?apply?changes. ?

修復完畢重啟cobbler服務，然后運行cobbler?sync ?

7：修復完成以上問題后，同步信息再檢查 ?

/etc/init.d/cobblerd?restart ?

Stopping?cobbler?daemon:???????????????????????????????????[??OK??] ?

Starting?cobbler?daemon:???????????????????????????????????[??OK??] ?

再次檢查，又報錯 ?

cobbler?check?

The?following?are?potential?configuration?items?that?you?may?want?to?fix: ?

?

1?:?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 ?

Restart?cobblerd?and?then?run?'cobbler?sync'?to?apply?changes.

報錯原因是上面的第五個問題沒完全解決，僅僅生成了密鑰，沒有放入cobbler主配置文件 ?

vim??/etc/cobbler/settings ?

default_password_crypted:?"$1$random-p$Q1IN9LaNg7yhRKJuY50fV1"?

再重啟服務 ?

執行cobbler?sync會重啟相關服務，DHCP服務也會啟動了，第一個提示也就解決了，下面也有說明?

執行cobbler sync即可啟動dhcp服務

使用koan重裝系統時報錯

??File?"/usr/lib/python2.4/site-packages/koan/configurator.py",?line?36,?in?? ?

????import?simplejson?as?json??

ImportError:?No?module?named?simplejson?

解決：需要安裝simplejson軟件包，
最新版下載地址：http://pypi.python.org/pypi/simplejson/
最新版的simplejson要求python 2.6+以上的,CntOS5.8是Python 2.4.3，所以下載的simplejson-2.0.9.tar.gz版本
https://pypi.python.org/packages/source/s/simplejson/simplejson-2.0.9.tar.gz
安裝步驟:
訪問外網下載文件setuptools-0.6c7-py2.4.egg
如沒有外網可以通過其他機器下載https://pypi.python.org/packages/2.4/s/setuptools/setuptools-0.6c7-py2.4.egg
然后上傳至客戶機再繼續安裝

tar?zxf?simplejson-2.0.9.tar.gz???

cd?simplejson-2.0.9 ?

python?setup.py?install??

建議CentOS5.8 安裝此版本的koan使用可以避免此問題
ftp://rpmfind.net/linux/epel/5/i386/koan-1.6.6-1.el5.noarch.rpm

解決方法詳見步驟8.2、8.3，詳細如下：

8.2?安裝電源管理工具cman

yum install cman -y

Cobbler代碼維護者jimi告知：某些系統版本將執行程序安裝在/sbin/目錄下，通過rpm -ql cman查看，CentOS5.8下如此解決即可

ln -s /sbin/fence_* /usr/sbin/

8.3?修改電源管理python腳本

備份

cp??/usr/lib/python2.4/site-packages/cobbler/action_power.py /usr/lib/python2.4/site-packages/cobbler/action_power.py.$(date +%F)

編輯

vim /usr/lib/python2.4/site-packages/cobbler/action_power.py?

刪除或注釋此文件如下代碼

utils.die(self.logger,"command succeeded (rc=%s), but output ('%s') was not understood" % (rc, output))

刪除文件action_power.pyo?、?action_power.pyc

這兩個文件在目錄/usr/lib/python2.4/site-packages/cobbler/下

重啟cobbler，注意一定是重啟cobbler
