以下是我使用Red hat 6.0的一些笔记，与大家分享。
使用APACHE提供虚拟主机WEB SERVER
-------------------------------------
1. 先把主机配置为多主址, 在X下运行linuxconf命令:
在Server栏下配置virtual host, 选定网卡eth0, 配置其IP和MASK.
原始IP：192.168.0.241
掩码 ：255.255.255.0
Virtual host IP Mask
------------------------------------------
192.168.0.242 255.255.255.0
192.168.0.243 255.255.255.0
192.168.0.244 255.255.255.0
192.168.0.245 255.255.255.0
192.168.0.246 255.255.255.0
2. 编辑/etc/httpd/conf/httpd.conf文件, 在最后加入:
DocumentRoot /home/httpd/html/241/Hardware.AIX
ServerName bbs1.ttsc.hl.cn
DocumentRoot /home/httpd/html/242/Networking.AIX
ServerName bbs2.ttsc.hl.cn
DocumentRoot /home/httpd/html/243/Security.AIX
ServerName bbs3.ttsc.hl.cn
DocumentRoot /home/httpd/html/244/Unix.AIX
ServerName bbs4.ttsc.hl.cn
DocumentRoot /home/httpd/html/245/WinNT.AIX
ServerName bbs5.ttsc.hl.cn
DocumentRoot /home/httpd/html/246/XWindow.AIX
ServerName bbs6.ttsc.hl.cn
3. 建立目录, 拷入WEB文档.
mkdir /home/httpd/html/241/Hardware.AIX
mkdir /home/httpd/html/242/Networking.AIX
mkdir /home/httpd/html/243/Security.AIX
mkdir /home/httpd/html/244/Unix.AIX
mkdir /home/httpd/html/245/WinNT.AIX
mkdir /home/httpd/html/246/XWindow.AIX
4. 重新启动httpd服务.
/usr/sbin/httpd stop
/usr/sbin/httpd start
5. OK, 现在可以在其他机器上访问
http://192.168.0.241/
http://192.168.0.242/
http://192.168.0.243/
http://192.168.0.244/
http://192.168.0.245/
http://192.168.0.246/

在REDHAT6.0上配置DHCP服务
=====================================
条件:
---------
子网掩码: 255.255.255.0
租借地址: 192.168.0.181 ~ 192.168.0.190
192.168.0.201 ~ 192.168.0.220
固定IP: 192.168.0.188 ~ 08:00:2b:4c:59:23
缺省网关: 192.168.0.254
DNS地址: 202.97.227.93, 192.168.0.241
建立步骤如下：
=================
安装DHCPD服务程序：
-------------------------
可以到下面的网址取得
ftp://ftp.isc.org/isc/dhcp/
在你下载之後，你必须将它解开。然後进入解开的目录，输入：
./configure
要做好安装前设定，可能要会花点时间。後随输入：
make
以及
make install
校验核心：
---------------
请输入 ifconfig -a，你将看到如下的讯息：
--------------------------------------------------------------------------------
eth0 Link encap:10Mbps Ethernet HWaddr 00:C0:4F:D3:C4:62
inet addr:183.217.19.43 Bcast:183.217.19.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:2875542 errors:0 dropped:0 overruns:0
TX packets:218647 errors:0 dropped:0 overruns:0
Interrupt:11 Base address:0x210
--------------------------------------------------------------------------------
如果未显示 MULTICAST 的讯息，你应该重新设定你的核心，加入对“多址传播(multicast)” 的支援。
对於大多数的系统而言，你几乎都不必如此做。
需要加入动态路由：
---------------------
输入：
route add -host 255.255.255.255 dev eth0
如果你看到如下的讯息
"255.255.255.255: Unknown host"
你应该将下面的资讯加入到 /etc/hosts 档案中：
255.255.255.255 all-ones
然後，输入：
route add -host all-ones dev eth0
或
route add -net 255.255.255.0 dev eth0
eth0 应该是你目前使用网路卡的装置名称。如果不是，你得配合实际情况做正确的修改。
需要配置文件:
----------------------
/etc/dhcpd.conf
/etc/dhcpd.leases 初次配置只需建立文件名(内部为空), 当有客户租用时
系统自动写入租用记录;
调试命令:
-----------------------------
/usr/sbin/dhcpd 停止DHCP服务;
/usr/sbin/dhcpd 启动DHCP服务;
/usr/sbin/dhcpd -d -f 启动并放到前台调试;
在/etc下配置dhcpd.conf文件如下:
-----------------------------------------------------------------------
[root@lee2 /etc]# more dhcpd.conf
default-lease-time 6000;
max-lease-time 72000;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.0.255;
option routers 192.168.0.254;
option domain-name-servers 202.97.227.93, 192.168.0.241;
option domain-name "ttsc.hl.cn";
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.181 192.168.0.190;
range 192.168.0.201 192.168.0.220;
}
#fix ip
host haagen {
hardware ethernet 08:00:2b:4c:59:23;
fixed-address 192.168.0.188;
}
