请教高手，我的httpd start 启动失败，显示的结果如下：
# service httpd start
正在启动 httpd：(99)Cannot assign requested address: make_sock: could not bind to address 192.168.10.151:8080
no listening sockets available, shutting down
Unable to open logs 失败
不知何故？另外请教服务器的ip地址是否可以任意设置，端口也是否可以任意设置？
请高手指点，在下感激不尽！！

进行软件更新时出了ERROR，如下所示：
Error Type: <class 'yum.Errors.RepoError'>

File : /usr/lib/python2.6/site-packages/yum/repos.py, line 121, in getRepo
'Error getting repository data for $s, repository not found' $ (repoid)

这是怎么回事？如何解决？
谢谢
