linux – IPvsadm在wlc调度程序上不能平衡

我的ldirectord.cf文件如下所示：

quiescent     = yes
autoreload    = yes
checktimeout  = 10
checkinterval = 10

# *.example.com http
virtual = 192.0.2.111:http
    real = 10.10.10.1:http  ipip    10
    real = 10.10.10.2:http  ipip    10
    real = 10.10.10.3:http  ipip    10
    real = 10.10.10.4:http  ipip    10
    real = 10.10.10.5:http  ipip    10
    scheduler = lc
    protocol = tcp
    service = http
    checktype = negotiate
    request = "/lb"
    receive = "Up and running"
    virtualhost = "site.com"
    fallback = 127.0.0.1:http

我认为可能导致问题的奇怪之处(但我真的不确定)是ipvsadm似乎没有正确跟踪活动连接,它们都显示为非活动连接

IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn    
TCP  192.0.2.111:http lc
  -> 10.10.10.1:http              Tunnel  10     0          10        
  -> 10.10.10.2:http              Tunnel  10     0          18        
  -> 10.10.10.3:http              Tunnel  10     0          3         
  -> 10.10.10.4:http              Tunnel  10     0          10        
  -> 10.10.10.5:http              Tunnel  10     0          5

如果我做ipvsadm -Lnc然后我看到很多连接,但只有ESTABLISHED& FIN_WAIT说明.

我以前在基于Gentoo的负载均衡器上使用ldirectord,而activeconn曾经是准确的,因为转移到Ubuntu 10.4 LTS似乎有所不同.

# ipvsadm -v
ipvsadm v1.25 2008/5/15 (compiled with popt and IPVS v1.2.1)

那么,ipvsadm是不是正确跟踪活动连接,从而使负载平衡工作不正确,如果是这样,我该如何让它再次正常工作？

编辑：它变得更奇怪,如果我cat / proc / net / ip_vs然后它看起来像正确的activeconns：

IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP  C000026F:0050 rr 
  -> 0AB42453:0050      Tunnel  10     1          24        
  -> 0AB4321D:0050      Tunnel  10     0          23        
  -> 0AB426B2:0050      Tunnel  10     2          25
