Cobbler報錯處理html

經過cobbler check檢查出現的報錯node

紅色標註爲報錯關鍵信息python

9.1 報錯一

# cobbler check
httpd does not appear to be running and proxying cobbler, or SELinux is in the way. Original traceback:

解決啓動httpd服務linux

service httpd start
Starting httpd: Syntax error on line 10 of /etc/httpd/conf.d/cobbler.conf:
Invalid command 'WSGIScriptAliasMatch', perhaps misspelled or defined by a module not included in the server configuration
[FAILED]#啓動httpd時的報錯，解決方法以下

解決git

vim /etc/httpd/conf.d/wsgi.conf
去掉註釋
LoadModule wsgi_module modules/mod_wsgi.so
再啓動httpd服務
service httpd start
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using x.x.x.x for ServerName
[ OK ]

再進行一些針對apache ServerName參數配置的處理github

egrep "ServerName|Listen" /etc/httpd/conf/httpd.conf |grep -v '#'
Listen 172.17.10.14:80
ServerName 80

9.2 報錯二

此步共修復七個須要處理的提示，一個一個解決shell

# cobbler check
The following are potential configuration items that you may want to fix:
1 : service dhcpd is not running
解決：DHCP先不處理
2 : 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.
解決：執行 cobbler get-loaders，系統將自動下載loader程序，完成提示2的修復工做。

*** TASK COMPLETE ***
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。若是不是安裝 debian之類的系統，此提示能夠忽略，若是須要安裝，
安裝 debmirror
yum -y install debmirror
編輯註釋
修改 /etc/debmirror.conf 配置文件，註釋掉 @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，可使用以下命令生成密碼，並使用生成後的密碼替換/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工具用於電源管理
yum -y install cman
Restart cobblerd and then run 'cobbler sync' to apply changes.
修復完畢重啓cobbler服務，而後運行cobbler sync
7：修復完成以上問題後，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.
報錯緣由是上面的第五個問題沒徹底解決，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"
再重啓服務
/etc/init.d/cobblerd restart
Stopping cobbler daemon: [ OK ]
Starting cobbler daemon: [ OK ]

*** TASK COMPLETE ***
執行cobbler sync會重啓相關服務，DHCP服務也會啓動了，第一個提示也就解決了，下面也有說明

9.3 報錯三

[root@cobbler-1014 x86_64]# /etc/init.d/cobblerd restart
Stopping cobbler daemon: [FAILED]
Starting cobbler daemon: [ OK ]
[root@cobbler-1014 x86_64]# cobbler check
The following are potential configuration items that you may want to fix:
1 : service dhcpd is not running
Restart cobblerd and then run 'cobbler sync' to apply changes.

執行cobbler sync便可啓動dhcp服務apache

cobbler sync

9.4 報錯四json

使用koan重裝系統時報錯

koan --server=172.17.10.14 --list=profiles
Traceback (most recent call last):
File "/usr/bin/koan", line 18, in ?
import koan.app as app
File "/usr/lib/python2.4/site-packages/koan/app.py", line 64, in ?
import configurator
File "/usr/lib/python2.4/site-packages/koan/configurator.py", line 36, in ?
import simplejson as json
ImportError: No module named simplejson

解決：須要安裝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，因此下載的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
如沒有外網能夠經過其餘機器下載https://pypi.python.org/packages/2.4/s/setuptools/setuptools-0.6c7-py2.4.egg
而後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使用能夠避免此問題
ftp://rpmfind.net/linux/epel/5/i386/koan-1.6.6-1.el5.noarch.rpm

9.5 報錯五

xen package needs to be installed

Xen 宿主機安裝虛擬機時提示沒有安裝xen軟件包
解決：

yum install xen -y

執行此命令會安裝一共9個軟件包，以下

解決：
報錯緣由是xend服務沒有啓動，執行如下命令處理

chkconfig xend on
/etc/init.d/xend start
#注意此過程會自動橋接網卡，可能出現短暫斷網

解決

我安裝的
系統版本:CentOS5.8 64bit
koan版本:koan-2.2.3-2.el5
xen版本：xen-3.0.3-142.el5_9.2
經過EPEL安裝的koan版本爲koan-2.2.3-2.el5，使用中報錯較多，後更換爲koan-1.6.6-1.el5此版本比較穩定，下載連接：ftp://rpmfind.net/linux/epel/5/i386/koan-1.6.6-1.el5.noarch.rpm

9.9 報錯九

cobbler check
The following are potential configuration items that you may want to fix:
1 : comment 'dists' on /etc/debmirror.conf for proper debian support
2 : comment 'arches' on /etc/debmirror.conf for proper debian support
Restart cobblerd and then run 'cobbler sync' to apply changes.

解決
關於debmirror編輯註釋
修改 /etc/debmirror.conf 配置文件，註釋掉 @dists 和 @arches 兩行

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

9.10 報錯十

/usr/bin/ipmitool power status
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory
Unable to get Chassis Power Status

解決

/etc/init.d/ipmi start
Starting ipmi drivers: [ OK ]
/etc/rc.d/init.d/ipmievd start
Starting ipmievd:
ipmievd: using pidfile /var/run/ipmievd.pid0
chkconfig ipmi on
chkconfig ipmievd on

再執行查看電源狀態

/usr/bin/ipmitool power status
Chassis Power is on

9.11 報錯十一

解決
選擇合適的power類型，報錯後面已經列出可選參數，我這裏使用的DELL PE1950應該選擇ipmilan

cobbler system edit --name=host-188116 --power-address=172.17.11.20 --power-type='ipmilan' --power-user=root --power-pass=djxxxx
