/sbin/ipvsadm -A -t 192.168.7.110:telnet -s rr
/sbin/ipvsadm -A -t 192.168.7.110:http - rr
/sbin/ipvsadm -a -t 192.168.7.110:telnet -r 192.168.7.11 -g -w 1
/sbin/ipvsadm -a -t 192.168.7.110:http -r 192.168.7.11 -g -w 1

然后运行：/etc/rc.d/init.d/ipvsadm save
就能够保存当前配置到/etc/sysconfig/ipvsadm文档中。
在具备HA系统的Director上，ipvsadm能够方便地被Heartbeat管理－启动、停止。Director上的VIP（虚拟）服务器地址由Heartbeat负责配置和转换。
做法如下：
在Heartbeat的配置文档haresources中加类似入如下一行：
linuxha1 IPaddr::192.168.7.110/24/192.168.7.255 ipvsadm ldirectord::www ldirectord::mail
2.6.3.2. RealServers上:
#!/bin/bash
#----------mini-rc.lvs_dr-realserver------------------
#installing default gw 192.168.7.254 for vs-dr
/sbin/route add default gw 192.168.7.254
#showing routing table
/bin/netstat -rn
#checking if DEFAULT_GW 192.168.1.254 is reachable
ping -c 1 192.168.7.254
#set_realserver_ip_forwarding to OFF (1 on, 0 off).
echo 0 >/proc/sys/net/ipv4/ip_forward
cat /proc/sys/net/ipv4/ip_forward
#looking for DIP 192.168.7.9
ping -c 1 192.168.7.9
#looking for VIP (will be on director)
ping -c 1 192.168.7.110
#install_realserver_vip
/sbin/ifconfig lo:0 192.168.7.110 broadcast 192.168.7.110 netmask 255.255.255.255 up
#ifconfig output
/sbin/ifconfig lo:0
#installing route for VIP 192.168.1.110 on device lo:0
/sbin/route add -host 192.168.7.110 dev lo:0
#listing routing info for VIP 192.168.7.110
/bin/netstat -rn
#hiding interface lo:110, will not arp
echo 1 >/proc/sys/net/ipv4/conf/all/hidden
cat /proc/sys/net/ipv4/conf/all/hidden
echo 1 >/proc/sys/net/ipv4/conf/lo/hidden
cat /proc/sys/net/ipv4/conf/lo/hidden
#----------mini-rc.lvs_dr-realserver------------------

该段脚本和上面的脚本比较类似，相信不用再多做介绍了。需要注意的是：LVS-DR模式下，缺省网关的配置。集群的网关是外部网关，而不是负载均衡
器。更有就是RealServer上绑定的VIP地址的设备lo:0。另外不要忘了开启not arp补丁的配置开关。相信您已很清楚了。
您也能够把以上脚本改写成符合init语法的标准脚本，放到/etc/rc.d/init.d/下面运行，或直接加到/etc/init.d/rc.local下运行。
改写为标准init语法脚本如下：
#!/bin/bash
#
# hidden This shell script takes care of starting and stopping
# the ipvs-hidden subsystem (hiddend).
#
# chkconfig: 2345 78 12
# description: ipvs-hidden
# processname: hiddend
prog="hidden"
start(){
echo 0 >/proc/sys/net/ipv4/ip_forward
/sbin/ifconfig lo:0 192.168.7.110 broadcast 192.168.7.110 netmask 255.255.255.255 up
# installing route for VIP 192.168.1.110 on device lo:0
/sbin/route add -host 192.168.7.110 dev lo:0
# listing routing info for VIP 192.168.7.110
/bin/netstat -rn
# hiding interface lo:0, will not arp
# echo 1 >/proc/sys/net/ipv4/conf/all/hidden
echo 1 >/proc/sys/net/ipv4/conf/lo/hidden
}
stop(){
echo 1 >/proc/sys/net/ipv4/ip_forward
/sbin/ifconfig lo:0 192.168.7.110 broadcast 192.168.7.110 netmask 255.255.255.255 down
/sbin/route del -host 192.168.7.110 dev lo:0
# echo 0 >/proc/sys/net/ipv4/conf/all/hidden
echo 0 >/proc/sys/net/ipv4/conf/lo/hidden
}
restart(){
stop
start
}
condrestart(){
[ -e /var/lock/subsys/hiddend ] && restart || :
}
# See how we were called.
case "" in
start)
start
;;
stop)
stop
;;
restart)
stop
start
;;
*)
echo $"Usage: "
exit 1
esac
exit $?
|
然后：
cp rc.lvs /etc/rc.d/init.d/hiddend
chmod 755 /etc/rc.d/init/d/hiddend
chkconfig - -add hiddend
