-----------先使用rpm -qa查詢當下系統是否具有httpd包
-----------有？直接service httpd start開啟服務
-----------沒有？下載or上傳包，然后，rpm -ivh xxx 安裝

有
---------查詢看有沒有
[root@sink ~]# rpm -qa httpd
httpd-2.2.3-6.el5
--------有，系統已將安裝上了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  ]
沒有
--------查詢看看有沒有
[root@sink ~]# rpm -qa httpd
...
---------------沒有，那么，首先創建上傳目錄，再rz上傳軟件包
[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
---------cd到soft目錄下面，ls確定一下
[root@sink soft]# ls
httpd-2.2.3-6.el5.x86_64.rpm
---------find路徑
[root@sink ~]# find / -name '*httpd-2.2.3-6.el5*'
/soft/httpd-2.2.3-6.el5.x86_64.rpm
---------嗯，沒錯，那么rpm -ivh xxx 直接安裝
[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
Preparing...                ########################################### [100%]
   1:httpd                  ########################################### [100%]
--------安裝好了，直接service httpd start就可以使用了
Starting httpd: httpd: Could not reliably determine the server's fully
qualified domain name, using 127.0.0.1 for ServerName
                                                                                             [  OK  ]
PS：httpd的軟件包就得自己網上下載了這里就不提供資源了
