-----------先使用rpm -qa查询当下系统是否具有httpd包
-----------有？直接service httpd start开启服务
-----------没有？下载or上传包，然后，rpm -ivh xxx 安装
有
---------查询看有没有
[root@sink ~]# rpm -qa httpd
httpd-2.2.3-6.el5
--------有，系统已将安装上了httpd，直接
[root@sink ~]# service httpd start
Starting httpd: httpd: Could not reliably determine the server's fully
qualified domain name, using 127.0.0.1 for ServerName
[ OK ]
没有
--------查询看看有没有
[root@sink ~]# rpm -qa httpd
...
---------------没有，那么，首先创建上传目录，再rz上传软件包
[root@sink ~]# mkdir /soft
[root@sink ~]# ls /
bin dev etc lib lost+found misc net proc sbin soft sys tmp usr
boot dsk1 home lib64 media mnt opt root selinux srv tftpboot u01 var
[root@sink ~]# cd /soft/
[root@sink soft]# ls
...
[root@sink soft]#rz
---------cd到soft目录下面，ls确定一下
[root@sink soft]# ls
httpd-2.2.3-6.el5.x86_64.rpm
---------find路径
[root@sink ~]# find / -name '*httpd-2.2.3-6.el5*'
/soft/httpd-2.2.3-6.el5.x86_64.rpm
---------嗯，没错，那么rpm -ivh xxx 直接安装
[root@sink soft]# rpm -ivh httpd-2.2.3-6.el5.x86_64.rpm
warning: httpd-2.2.3-6.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
