lvs dr模式安装
lvs dr模式安装环境：centos5.5 （注：测试环境均为centos5.5，在虚拟机上虚拟三个centos系统）
vip 192.168.3.169
lb真是ip192.168.3.168
server1 ip:192.168.10.2
server1 ip:192.168.10.3
rpm包安装ipvsadmin
I lb上边配置
1 复制网卡ifcfg-eth0:1
DEVICE=eth0:1
BOOTPROTO=none
IPADDR=192.168.3.169
NETMASK=255.255.0.0
ONBOOT=yes
2 开启路由转发功能 vim /etc/sysctl.conf
net.ipv4.ip_forward = 1
3添加脚本
#!/bin/sh
ipvsadm -C
ipvsadm -A -t 192.168.3.169:80 -s wlc
ipvsadm -a -t 192.168.3.169:80 -r 192.168.10.2 -g
ipvsadm -a -t 192.168.3.169:80 -r 192.168.10.3 -g
II server上边配置
1 cp换回接口 ifcfg-lo:1
DEVICE=lo:1
IPADDR=192.168.3.169
NETMASK=255.255.255.255
NETWORK=192.168.3.169
ONBOOT=yes
ARP=no
2开启路由转发 vim /etc/sysctl.conf
net.ipv4.ip_forward = 1
添加
net.ipv4.conf.lo.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
使用sysctl -p 保存
两台服务器同样的配置
III 在lb上启动ipvsadm
service ipvsadm start
Clearing the current IPVS table: [确定]
Applying IPVS configuration: /etc/init.d/ipvsadm: line 62: /etc/sysconfig/ipvsadm: 没有那个文件或目录
[失败]
出现这样的错误service ipvsadm save 然后再重启
运行刚才的脚本
查看状态
ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
