cobbler，重启系统cobbler check 报错error: [Errno 111] Connection refused





报错如下：
[root@client ~]# cobbler check
httpd does not appear to be running and proxying cobbler, or SELinux is in the way. Original traceback:

解决方法：
1.检查http有没有启动
没启动的话启动http
启动可能报错
官方的说法是

Please make sure your apache is also bound to localhost.
1、service httpd restart
2、if httpd didn't OK,
vi /etc/httpd/conf/httpd.conf
ServerName 127.0.0.1
问题解决。。。
