关于lvs多个端口，状态保持的问题

Submitted by linkvi on 周三, 2011-10-12 03:23

我想问一下，lvs能不能实现对多个端口的状态保持，就是比如我 对80和443都做了负载均衡，那么能不能根据算法 第一次访问80的session ，在没有超时的情况下，会选择相同主机的443端口?

应该是可以的吧，ipvsadm -a service_addr:port -r server_addr:port，这样是可以把80端口的包都redirect到443端口的，至于同时redirect到两个端口，没有尝试过
例如：
ipvsadm -a 202.143.44.67:80 -r 192.168.2.1:80 -s rr
ipvsadm -a 202.143.44.67:80 -r 192.168.2.1:443 -s rr
如果是按规则来做rr的话，理论上是可以同时redirect到80和443的，但没有做过相应的实验，所以不保证这个结论正确

ipvsadm -a 202.143.44.67:80 -r 192.168.2.1:80 -s rr
ipvsadm -a 202.143.44.67:80 -r 192.168.2.1:443 -s rr
下边的一条前后端口必须保持一致
可以另外加A 但是前后端口必须保持一致才行不然做不了
