四．配置real-server2的web服务器：
4.1 解决arp问题:
[root@ ~]# hostname r2.junjie.com
注销重新登录
[root@r2 ~]# echo "net.ipv4.conf.all.arp_announce = 2" >> /etc/sysctl.conf
[root@r2 ~]# echo "net.ipv4.conf.lo.arp_announce = 2" >> /etc/sysctl.conf
[root@r2 ~]# echo "net.ipv4.conf.all.arp_ignore = 1" >> /etc/sysctl.conf
[root@r2 ~]# echo "net.ipv4.conf.lo.arp_ignore = 1" >> /etc/sysctl.conf
[root@r2 ~]# sysctl -p
net.ipv4.conf.all.arp_announce = 2
net.ipv4.conf.lo.arp_announce = 2
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.lo.arp_ignore = 1
4.2 配置ip地址和路由
[root@r2 ~]# setup
[root@r2~]# service network restart
Shutting down interface eth0: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [ OK ]
[root@r2 ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:0C:29:AE:83:D1
inet addr:10.106.6.252 Bcast:10.106.6.255 Mask:255.255.255.0
[root@r2 ~]# ifconfig lo:0
lo:0 Link encap:Local Loopback
inet addr:10.106.6.254 Mask:255.255.255.255
[root@r2 ~]# route -n

[root@r2 ~]# route add -host 10.106.6.254 dev lo:0
[root@r2 ~]# route -n

Destination Gateway Genmask Flags Metric Ref Use Iface
10.106.6.254 0.0.0.0 255.255.255.255 UH 0 0 0 lo

169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
0.0.0.0 10.106.6.254 0.0.0.0 UG 0 0 0 lo
4.3 配置Real-server-2的Web服务器：
[root@r2 ~]#mkdir /mnt/cdrom
[root@r2 ~]# mount /dev/cdrom /mnt/cdrom/
mount: block device /dev/cdrom is write-protected, mounting read-only
[root@r2 ~]# rpm -ivh /mnt/cdrom/Server/httpd-2.2.3-31.el5.i386.rpm
warning: /mnt/cdrom/Server/httpd-2.2.3-31.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
Preparing... #################################### [100%]
1:httpd ########################################### [100%]
[root@r2 ~]#echo "web2 -- real-server-2" > /var/www/html/index.html l
[root@r2 ~]# service httpd start
Starting httpd: httpd: apr_sockaddr_info_get() failed for r2.junjie.vom
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[ OK ]
4.4 客户端访问real-server-2的web服务：（桥接）
