先配置内核参数 再配置vip 1. 配置内核参数 arp_announce :INTEGER 不同取值表示对网络接口上本地IP地址发出的ARP回应作出相应级别的限制：相关代码在 默认为0 8 -不回应所有（本地地址）的arp查询 [root@server ~]# sysctl -a |grep announce |head -1 >>/etc/sysctl.conf [root@server ~]# sysctl -a |grep ignore |head -1 >>/etc/sysctl.conf [root@server ~]# vim /etc/sysctl.conf net.ipv4.conf.all.arp_announce = 2 net.ipv4.conf.lo.arp_announce = 2 net.ipv4.conf.lo.arp_ignore= 1 net.ipv4.conf.all.arp_ignore=1 --必须先配置内核参数才配置vip。 2.配置地址 [root@server ~]# ifconfig lo:0 192.168.2.100 netmask 255.255.255.255 --vip要配置在逻辑端口上 [root@server ~]# route add -host 192.168.2.100 dev lo:0 --针对主机的路由，返回接口是lo:0 [root@server1 ~]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.2.100 .0 255.255.255.255 UH 0 0 0 lo 192.168.2.0 .0 255.255.255.0 U 0 0 0 eth0 192.168.2.0 .0 255.255.255.0 U 0 0 0 eth1 [root@server1 ~]# [root@server ~]# 3.安装apache [root@server ~]# [root@server ~]# mount /dev/cdrom /mnt/cdrom [root@server ~]# cd /mnt/cdrom/Server/ [root@server Server]# rpm -ivh httpd--22.el5.i386.rpm [root@server Server]# vim /var/www/html/index.html hello,test lvs-dr page from server1! ~ [root@server Server]# service httpd start Starting httpd: [ OK ] [root@server Server]# 4,。配置server2 [root@server Server]# scp /etc/sysctl.conf 192.168.2.30:/etc The authenticity of host '192.168.101.10 (192.168.101.10)' can't be established.
