????? 用python搞了一個從excel中讀取cobbler節點信息并加入cobbler中的腳本，運行的過程中出了不少問題，這里記錄下來，方便日后查找！

?

一、yum install python，我通過這個命令安裝python，默認安裝的是2.6的版本，但是當我把python 2.6安裝完成后，發現cobbler的WEB管理頁面無法打開了，查看apahce的錯誤日志：

缺少urandom模塊，python2.6版本里默認沒有這個模塊，隨即將python升級到2.7版本。

升級過程：

1、下載Python 2.7源碼：

? wget http://www.python.org/ftp/python/2.7.2/Python-2.7.2.tgz

下載

2、解壓源碼包：

???tar -zxvf Python-2.7.2.tgz

3、編譯：

???cd Python-2.7.2

?? ./configure??--prefix=/usr

4、make&&make install

安裝完成后測試web界面可以正常打開了，但是使用yum安裝軟件的時候會發現不能使用，原因是yum與python有依賴關系，yum是急于python寫的，運行yum命令時會調用pyton；

vi /usr/bin/yum

將#！/usr/bin/pyton 改成：#！/usr/bin/pyton2.6，改成你系統默認的版本即可，不然他會調用高版本的python軟件包，但是是找不到的，需要做相關配置才行，這里為了方便就直接改了就可以使用了。

二、在安裝了python2.7后執行cobbler的相關命令也會有問題

[root@cobbler scripts]# ./addnode2.py cobbler.xls add test1 aa:bb:cc:dd 19:2.:16:8.:0.:2 add test2 aa:bb:cc:dd 19:2.:16:8.:0.:3 [root@cobbler scripts]# Traceback (most recent call last):File "/usr/bin/cobbler", line 17, in <module>import cobbler.cli as app ImportError: No module named cobbler.cli Traceback (most recent call last):File "/usr/bin/cobbler", line 17, in <module>import cobbler.cli as app ImportError: No module named cobbler.cli[root@cobbler scripts]# cobbler get-loaders Traceback (most recent call last):File "/usr/bin/cobbler", line 17, in <module>import cobbler.cli as app ImportError: No module named cobbler.cli

這也是由于python版本導致的，同樣：vi /usr/bin/cobbler

將調用的python版本修改為2.6即可。

三、補充：關于安裝EasyInstall 遇到的問題：

下載：

wget http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg

安裝：

sh setuptools-0.6c11-py2.7.egg

報錯：

Traceback (most recent call last): File "<string>", line 1, in <module> zipimport.ZipImportError: can't decompress data; zlib not available

?

解決方法：

1、安裝依賴zlib、zlib-devel

2、重新編譯安裝Python

?

./configure 編輯Modules/Setup文件 找到下面這句，去掉注釋 #zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz 重新編譯安裝：make & make install

?
