3 RS配置
a) 安装系统
# 参见lvs-fullnat-synproxy.tar中的README,其中有TOA(RS内核)的patch；
b) 加载TOA模块，命令：# modprobe toa
# vim /etc/rc.local 添加 modproble toa
4日常操作（以集群模式为例） 4.1 添加/删除realserver
如果添加，请确保realserver的监听的port是打开的（可以telnet连接该端口）。 1) 第1步，配置realserver，具体参见附录5.1；
更新内核版本，加载相应的TOA模块：
# modprobe ttm.ko # vim /etc/rc.local 添加 modproble toa
2) 第2步，修改keepalived的配置，注意所有LVS上都得修改；
例如realserver的IP为10.251.X.X，业务名taobao
# vim /etc/keepalived/taobao.conf virtual_server group taobao { ……
real_server 10.251.X.X 80 { weight 1 TCP_CHECK {
connect_timeout 4 } } }
3) 第3步，发送HUP信号给keepalived，使配置修改生效；
# service keepalived reload
4) 第4步，检查realserver是否操作成功
在LVS上，分别运行ipvsadm -ln观察该realserver的健康检查是否成功，并在LVS查看session分配是否均匀。
4.2添加/删除vip
假设新添vip为1.1.1.3，业务名称taobao； 1) 修改keepalived配置文件，添加如下内容； 第一步，创建业务配置文件；
#vim /etc/keepalived/taobao.conf
virtual_server_group taobao { 1.1.1.3 80 //vip1 }
virtual_server group taobao { delay_loop 6
lb_algo rr lb_kind FNAT protocol TCP syn_proxy
laddr_group_name laddr_g1
alpha //启动alpha模式，以便自动绑定vip quorum 1 hysteresis 0
quorum_up \1.1.1.3/32 dev lo;\quorum_down \1.1.1.3/32 dev lo;\ }
……
第二步，修改keepalived配置文件；
#vim /etc/keepalived/keepalived.conf ……
! include virtual server configure file include www.conf include taobao.conf
2) 发送HUP信号给keepalived，使配置修改生效；
# service keepalived reload
3) 检查vip配置是否生效；
# ipvsadm –ln //查看vip是否已经配置到lvs中 # ip addr list //查看lo上vip是否绑定成功 # 模拟用户访问vip，结果是否正确
4.3 添加/删除local address
注：local address和内网接口ip绝对不能重合；
以添加/删除192.168.100.4为例，其内网网卡为eth1，需要配置2个地方： 1. 修改/etc/rc.local
添加ip addr add 192.168.100.4/32 dev eth1
2. 修改/etc/keepalived/keepalived.conf
#vim /etc/keepalived/keepalived.conf local_address_group laddr_g1 { }
……
192.168.100.4
3. 发送HUP信号给keepalived，使配置修改生效；
# service keepalived reload
4. 检查local address配置是否生效；
# ip addr list //查看网卡上是否已经绑定ip # ipvsadm –G //查看vip上是否已经绑定ip
