九、Cobbler报错处理



通过cobbler check检查出现的报错

红色标注为报错关键信息


9.1 报错一


 
  
     
   
  1. # cobbler check
    2.  
   
  2. httpd does not appear to be running and proxying cobbler, or SELinux isin the way. Original traceback:

  21.  raise socket.error, msg 
    22.  
   
  22. error: (111, 'Connection refused') 
    23.  
  
 
  
解决启动httpd服务
 
  
 
  
     
   
  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]#启动httpd时的报错，解决方法如下 
    5.  
  
 
  
解决
 
  
 
  
     
   
  1. vim /etc/httpd/conf.d/wsgi.conf 
    2.  
   
  2. 去掉注释 
    3.  
   
  3. LoadModule wsgi_module modules/mod_wsgi.so 
    4.  
   
  4. 再启动httpd服务 
    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.  
  
 
  
再进行一些针对apache ServerName参数配置的处理
 
  
 
  
     
   
  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 报错二
 
  

 
  
此步共修复七个需要处理的提示，一个一个解决
 
  
 
  

 
  
 
  
     
   
  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. 解决：DHCP先不处理 
    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. 解决：执行 cobbler get-loaders，系统将自动下载loader程序，完成提示2的修复工作。 
    7.  
   
  7. # cobbler get-loaders

    21.  
   
  21. 3 : debmirror package isnot installed, it will be required to manage debian deployments and repositories 
    22.  
   
  22. 解决：提示说debmirror没安装。如果不是安装 debian之类的系统，此提示可以忽略，如果需要安装， 
    23.  
   
  23. 安装 debmirror 
    24.  
   
  24. yum -y install debmirror 
    25.  
   
  25. 编辑注释 
    26.  
   
  26. 修改 /etc/debmirror.conf 配置文件，注释掉 @dists 和 @arches 两行 
    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. 解决：安装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. 解决：修改cobbler用户的默认密码，可以使用如下命令生成密码，并使用生成后的密码替换/etc/cobbler/settings中 default_password_crypted 的密码。 
    35.  
   
  35. 生成密码命令：
    36.  
   
  36. #openssl passwd -1 -salt 'random-phrase-here''[任意密码]'
    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. 解决:安装cman工具用于电源管理 
    43.  
   
  43. yum -y install cman 
    44.  
   
  44. Restart cobblerd andthen run 'cobbler sync'to apply changes. 
    45.  
   
  45. 修复完毕重启cobbler服务，然后运行cobbler sync 
    46.  
   
  46. 7：修复完成以上问题后，同步信息再检查 
    47.  
   
  47. /etc/init.d/cobblerd restart 
    48.  
   
  48. Stopping cobbler daemon: [ OK ] 
    49.  
   
  49. Starting cobbler daemon: [ OK ] 
    50.  
   
  50. 再次检查，又报错 
    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. 报错原因是上面的第五个问题没完全解决，仅仅生成了密钥，没有放入cobbler主配置文件
    57.  
   
  57. vim /etc/cobbler/settings 
    58.  
   
  58. default_password_crypted: "$1$random-p$Q1IN9LaNg7yhRKJuY50fV1"
    59.  
   
  59. 再重启服务 
    60.

    80.  
   
  80. *** TASK COMPLETE *** 
    81.  
   
  81. 执行cobbler sync会重启相关服务，DHCP服务也会启动了，第一个提示也就解决了，下面也有说明 
    82.  
  
 
  
9.3 报错三
 
  

 
  
 
  
     
   
  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.  
  
 
  
执行cobbler sync即可启动dhcp服务
 
  
 
  
     
   
  1. cobbler sync 
    2.  
  
 
  
 
  
9.4 报错四
 
  

 
  
使用koan重装系统时报错
 
  
 
  

 
  
 
  
     
   
  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.  
  
 
  
解决：需要安装simplejson软件包，
最新版下载地址：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，所以下载的simplejson-2.0.9.tar.gz版本
https://pypi.python.org/packages/source/s/simplejson/simplejson-2.0.9.tar.gz
安装步骤:
访问外网下载文件setuptools-0.6c7-py2.4.egg
如没有外网可以通过其他机器下载https://pypi.python.org/packages/2.4/s/setuptools/setuptools-0.6c7-py2.4.egg
然后上传至客户机再继续安装
 
  
 
  
     
   
  1. tar zxf simplejson-2.0.9.tar.gz 
    2.  
   
  2. cd simplejson-2.0.9 
    3.  
   
  3. python setup.py install 
    4.  
  
 
  
建议CentOS5.8 安装此版本的koan使用可以避免此问题
ftp://rpmfind.net/linux/epel/5/i386/koan-1.6.6-1.el5.noarch.rpm

解决方法详见步骤8.2、8.3，详细如下：
 
  
8.2 安装电源管理工具cman
 
  

 
  
 
   
yum install cman -y
 
   

 
  
 
  
Cobbler代码维护者jimi告知：某些系统版本将执行程序安装在/sbin/目录下，通过rpm -ql cman查看，CentOS5.8下如此解决即可 
 
  

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

 
  
 
  
8.3 修改电源管理python脚本
 
  

 
  
备份
 
  

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

 
  
 
  
编辑
 
  

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

 
  
删除或注释此文件如下代码
 
  

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

 
  
 
  
删除文件action_power.pyo 、 action_power.pyc
 
  

 
  
这两个文件在目录/usr/lib/python2.4/site-packages/cobbler/下
 
  

 
  
重启cobbler，注意一定是重启cobbler
 
  

 
  
 
   
cobbler reboot
 
   

 
  
 
  
步骤8.2、8.3是我在使用电源管理中发现的问题，后通过github与Cobbler代码维护者jimi沟通解决的，非常感谢他的帮助，详见
 
  

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

 
  

 
  
10. DHCP非Cobbler本机
 
  
 因为有的同学生产环境已有DHCP服务，Cobbler本机可以不用再安装配置DHCP，步骤如下：
 
  
配置不管理DHCP
 
  
vim /etc/cobbler/settings 
 
  
manage_dhcp: 0
 
  

 
  
重启cobbler
 
  
/etc/init.d/cobblerd restart
 
  

 
  
检查配置
 
  
cobbler check 
 
  

 
  
同步配置
 
  
cobbler sync 
 
  
DHCP服务配置next-server 指向cobbler服务器IP即可，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";
 
  
 }
