!!! TASK FAILED !!!

//原因是因为python的字符集编码不一致造成的
//解决办法如下
[root@manager-61 /]# cat >> /usr/lib/python2.7/site-packages/sitecustomize.py  <<EOF
# encoding=utf8 
import sys
reload(sys)
sys.setdefaultencoding('utf8')
EOF
//然后重启服务器

错误2，报错信息如下

[root@manager-61 ~]#  cobbler validateks    
httpd does not appear to be running and proxying cobbler, or SELinux is in the way. Original traceback:
Traceback (most recent call last):
这个是因为 http服务没有起来造成的，执行以下上面我们讲过的启动的那些服务即可 

错误3，进入到安装页面，能安装，但是在安装中出现错误提示磁盘没有可用的空间

原因是因为cobbler的客户端内存给小了，所以提示没有可用的空间，然后把客户端内存给大一点即可
