九、Cobbler報錯處理



經過cobbler check檢查出現的報錯

紅色標註爲報錯關鍵信息


9.1 報錯一

    22.  
  
  22. error: (111, 'Connection refused') 
    23.  
 
 
 
解決啓動httpd服務
 
 
 
 
     
  
  1. service httpd start 
    2.  
  
  2. Starting httpd: Syntax error on line 10 of /etc/httpd/conf.d/cobbler.conf: 
    3.  
  
  3. Invalid command 'WSGIScriptAliasMatch', perhaps misspelled or defined by a module not included in the server configuration 
    4.  
  
  4.  [FAILED]#啓動httpd時的報錯，解決方法以下 
    5.  
 
 
 
解決
 
 
 
 
     
  
  1. vim /etc/httpd/conf.d/wsgi.conf 
    2.  
  
  2. 去掉註釋 
    3.  
  
  3. LoadModule wsgi_module modules/mod_wsgi.so 
    4.  
  
  4. 再啓動httpd服務 
    5.  
  
  5. service httpd start 
    6.  
  
  6. Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using x.x.x.x for ServerName 
    7.  
  
  7.  [ OK ] 
    8.  
 
 
 
再進行一些針對apache ServerName參數配置的處理
 
 
 
 
     
  
  1. egrep "ServerName|Listen" /etc/httpd/conf/httpd.conf |grep -v '#'
    2.  
  
  2. Listen 172.17.10.14:80 
    3.  
  
  3. ServerName 80 
    4.

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
 
 
 
 

 
 
 
 
     
  
  1. # cobbler check
    2.  
  
  2. The following are potential configuration items that you may want to fix: 
    3.  
  
  3. 1 : service dhcpd isnot running 
    4.  
  
  4. 解決：DHCP先不處理 
    5.  
  
  5. 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.
    6.  
  
  6. 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。 
    7.  
  
  7. # cobbler get-loaders 
    8.

  20. *** TASK COMPLETE *** 
    21.  
  
  21. 3 : debmirror package isnot installed, it will be required to manage debian deployments and repositories 
    22.  
  
  22. 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， 
    23.  
  
  23. 安裝 debmirror 
    24.  
  
  24. yum -y install debmirror 
    25.  
  
  25. 編輯註釋 
    26.  
  
  26. 修改 /etc/debmirror.conf 配置文件，註釋掉 @dists 和 @arches 兩行 
    27.  
  
  27. sed -i 's|@dists=.*|#@dists=|' /etc/debmirror.conf 
    28.  
  
  28. sed -i 's|@arches=.*|#@arches=|' /etc/debmirror.conf 
    29.  
  
  29. 4 : ksvalidator was not found, install pykickstart
    30.  
  
  30. 解決：安裝ksvalidator 
    31.  
  
  31.  yum install pykickstart -y 
    32.  
  
    33.  
  
  33. 5 : The defaultpassword used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still setto'cobbler'and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'"to generate new one 
    34.  
  
  34. 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。 
    35.  
  
  35. 生成密碼命令：
    36.  
  
  36. #openssl passwd -1 -salt 'random-phrase-here''[任意密碼]'
    37.  
  
  37. openssl passwd -1 -salt 'random-phrase-here''hexun'
    38.  
  
  38. $1$random-p$Q1IN9LaNg7yhRKJuY50fV1 
    39.  
  

    40.  
  
  40. 6 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them 
    41.  
  

    42.  
  
  42. 解決:安裝cman工具用於電源管理 
    43.  
  
  43. yum -y install cman 
    44.  
  
  44. Restart cobblerd andthen run 'cobbler sync'to apply changes. 
    45.  
  
  45. 修復完畢重啓cobbler服務，而後運行cobbler sync 
    46.  
  
  46. 7：修復完成以上問題後，同步信息再檢查 
    47.  
  
  47. /etc/init.d/cobblerd restart 
    48.  
  
  48. Stopping cobbler daemon: [ OK ] 
    49.  
  
  49. Starting cobbler daemon: [ OK ] 
    50.  
  
  50. 再次檢查，又報錯 
    51.  
  
  51. cobbler check
    52.  
  
  52. The following are potential configuration items that you may want to fix: 
    53.  
  
    54.  
  
  54. 1 : The defaultpassword used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still setto'cobbler'and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'"to generate new one 
    55.  
  
  55. Restart cobblerd andthen run 'cobbler sync'to apply changes.
    56.  
  
  56. 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
    57.  
  
  57. vim /etc/cobbler/settings 
    58.  
  
  58. default_password_crypted: "$1$random-p$Q1IN9LaNg7yhRKJuY50fV1"
    59.  
  
  59. 再重啓服務 
    60.  
  
  60. /etc/init.d/cobblerd restart 
    61.  
  
  61. Stopping cobbler daemon: [ OK ] 
    62.  
  
  62. Starting cobbler daemon: [ OK ] 
    63.  
  
  63. cobbler check
    64.  
  
  64. No configuration problems found. All systems go. 
    65.

  73. received on stdout: Shutting down dhcpd: [ OK ] 
    74.

    80.  
  
  80. *** TASK COMPLETE *** 
    81.  
  
  81. 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 
    82.  
 
 
 
9.3 報錯三
 
 

 
 
 
 
     
  
  1. [root@cobbler-1014 x86_64]# /etc/init.d/cobblerd restart 
    2.  
  
  2. Stopping cobbler daemon: [FAILED] 
    3.  
  
  3. Starting cobbler daemon: [ OK ] 
    4.  
  
  4. [root@cobbler-1014 x86_64]# cobbler check
    5.  
  
  5. The following are potential configuration items that you may want to fix: 
    6.  
  
  6. 1 : service dhcpd isnot running 
    7.  
  
  7. Restart cobblerd andthen run 'cobbler sync'to apply changes. 
    8.  
 
 
 
執行cobbler sync便可啓動dhcp服務
 
 
 
 
     
  
  1. cobbler sync 
    2.  
 
 
 
 
 
9.4 報錯四
 
 

 
 
使用koan重裝系統時報錯
 
 
 
 

 
 
 
 
     
  
  1. koan --server=172.17.10.14 --list=profiles 
    2.  
  
  2. Traceback (most recent call last): 
    3.  
  
  3.  File "/usr/bin/koan", line 18, in ? 
    4.  
  
  4.  import koan.app as app 
    5.  
  
  5.  File "/usr/lib/python2.4/site-packages/koan/app.py", line 64, in ? 
    6.  
  
  6.  import configurator 
    7.  
  
  7.  File "/usr/lib/python2.4/site-packages/koan/configurator.py", line 36, in ? 
    8.  
  
  8.  import simplejson as json 
    9.  
  
  9. ImportError: No module named simplejson 
    10.  
 
 
 
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
 
 
 
 
     
  
  1. tar zxf simplejson-2.0.9.tar.gz 
    2.  
  
  2. cd simplejson-2.0.9 
    3.  
  
  3. python setup.py install 
    4.  
 
 
 
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

    6.  
 
 
 
Xen 宿主機安裝虛擬機時提示沒有安裝xen軟件包
解決：
 
 
 
 
     
  
  1. yum install xen -y 
    2.  
 
 
 
執行此命令會安裝一共9個軟件包，以下
 
 
 
 
     
  
  1. Running Transaction
    2.  
  
  2.  Installing : bridge-utils 1/9

    5.  
  
  5. xend needs to be started 
    6.  
 
 
 
 
 

 
 
解決：
報錯緣由是xend服務沒有啓動，執行如下命令處理
 
 
 
 
     
  
  1. chkconfig xend on
    2.  
  
  2. /etc/init.d/xend start 
    3.

解決方法詳見步驟8.2、8.3，詳細以下：
 
 
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，經過rpm -ql cman查看，CentOS5.8下如此解決便可 
 
 

 
 
 
  
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
 
 

 
 
刪除或註釋此文件以下代碼
 
 

 
 
 
  
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
 
 

 
 
重啓cobbler，注意必定是重啓cobbler
 
 

 
 
 
  
cobbler reboot
 
  

 
 
 
 
步驟8.2、8.3是我在使用電源管理中發現的問題，後經過github與Cobbler代碼維護者jimi溝通解決的，很是感謝他的幫助，詳見
 
 

 
 
https://github.com/cobbler/cobbler/issues/426
 
 

 
 

 
 
10. DHCP非Cobbler本機
 
 
 由於有的同窗生產環境已有DHCP服務，Cobbler本機能夠不用再安裝配置DHCP，步驟以下：
 
 
配置無論理DHCP
 
 
vim /etc/cobbler/settings 
 
 
manage_dhcp: 0
 
 

 
 
重啓cobbler
 
 
/etc/init.d/cobblerd restart
 
 

 
 
檢查配置
 
 
cobbler check 
 
 

 
 
同步配置
 
 
cobbler sync 
 
 
DHCP服務配置next-server 指向cobbler服務器IP便可，例如 
 
 
subnet 192.168.10.0 netmask255.255.255.0 {
 
 
 range 192.168.10. 192.168.10.240;
 
 
 option subnet-mask 255.255.255.0;
 
 
 option routers 192.168.10.254;
 
 
 next-server 192.168.4.194;
 
 
 filename"pxelinux.0";
 
 
 }
