Setting up Install Process
No package httpd available.
Nothing to do
解决方案:
1.卸载redhat自带的yum组件
[root@localhost ~]# rpm -qa|grep yum|xargs rpm -e –nodeps
2.安装CentOS的yum包
[root@localhost ~]# wget http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm
[root@localhost ~]# wget http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-fastestmirror-1.1.16-16.el5.centos.noarch.rpm
[root@localhost ~]# wget http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-3.2.22-37.el5.centos.noarch.rpm
[root@localhost ~]# rpm -ivh *.rpm

3. 下载更新源,并存放在系统目录中
[root@localhost ~]# wget http://www.linuxidc.com/files/2011/05/06/CentOS-Base.repo
[root@localhost ~]#mv CentOS_Base.repo /etc/yum.repos.d/CentOS-Base.repo
4.生成缓存并进行安装
[root@localhost ~]# yum makecache
[root@localhost ~]# yum install httpd
