gentoo上安装lvs

yakczh

ipvsadm -A -t 192.168.70.8:80 -s wlc
FATAL: Module ip_vs not found.
Can't initialize ipvs: Protocol not available
Are you sure that IP Virtual Server is built in the kernel or as module?
是不是要重新编译内核啊

druggo

LVS在内核中，你当然要编译内核来打开LVS了，ipvsadm只是一个操作LVS的工具而已。

重新编译了内核，加入了lvs支持，但还是没有配置成功
我的环境如下
两台linux server ip分别192.168.70.8  192.168.70.9  

192.168.70.8 做director  用192.168.70.100做虚拟ip 192.168.70.9 做realserver

192.168.70.8的配置
ifconfig eth0:0 192.168.70.100  broadcast 192.168.70.100 netmask  255.255.255.255 up
route add -host 192.168.70.100  dev eth0:0
echo "0" >/proc/sys/net/ipv4/ip_forward
echo "1" >/proc/sys/net/ipv4/conf/all/send_redirects  
echo "1" >/proc/sys/net/ipv4/conf/default/send_redirects
echo "1" >/proc/sys/net/ipv4/conf/eth0/send_redirects
ipvsadm -C
ipvsadm -A -t 192.168.70.100:80 -s rr
ipvsadm -a  -t 192.168.70.100:80 -r 192.168.70.9:80 -m -w 1
192.168.70.8 上停止了apache服务



192.168.70.9 做real server
ifconfig lo:0 192.168.70.100  broadcast 192.168.70.100  netmask 255.255.255.255  up
route add -host 192.168.70.100  dev lo:0
echo "0" >/proc/sys/net/ipv4/ip_forward
echo "1" >/proc/sys/net/ipv4/conf/all/hidden
echo "1" >/proc/sys/net/ipv4/conf/lo/hidden
192.168.70.9的机器上启动apache


局域网的其他机器测试  

telnet 192.168.70.100 80
正在连接到192.168.70.100...不能打开到主机的连接， 在端口 80: 连接失败

我想让192.168.70.100:80的请求能够到达192.168.70.9:80 但是不能成功，不知道是哪个地方出错了

稍微看了一下，你关闭ARP的方法在2.6内核里不行吧？，去lvs的官方网站好好看教程吧.
也可以参考一下我的记录： http://blog.druggo.net/index.php?post/2007/04/10/LVS-DRTUN
