tomcat負載平衡： Unable to start cluster receiver

我在windows下安裝用Vmware+Redhat，配置apache+tomcat+負載平衡的時候，出現了一個很奇怪的問題：

注意到：

這個問題很明顯是連接埠錯誤，但是就是找不到原因，我的主機ip192.168.137.3，我的Vmware的ip是192.168.124.134，我的windows下的tomcat啟動正常，但是在Redhatlinux下面的tomcat啟動的時候就出現了一個錯誤。在網上找了很多資料，都是說連接埠衝突，系統提示，也似乎是連接埠衝突，但是就是找不到原因，也找不到192.168.137.3：4099這個連接埠被誰用了，真是鬱悶，最後我重啟機器，首先啟動linux下面的tomcat錯誤
還是一樣的提示資訊。就是不知道：

Unable to bind server socket to:/192.168.137.3:4099 throwing erro

這句到底是在哪裡進行配置，我的虛擬機器裡怎麼會與192.168.137.3：4099綁定，找到下面那條語句：

org.apache.catalina.tribes.transport.nio.NioReceiver

最後，終於知道是設定檔server.xml檔案出錯了

 <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"                      address="auto"     //把這個改為localhost或都自己的ip都可以；如果用auto的話，在vmware裡會與主機的實際ip產生衝突，原因不知道是什麼，呵呵。                      port="4000"                      autoBind="100"                      selectorTimeout="5000"                      maxThreads="6"/>

重新啟動tomcat，感覺世界又美好了些！
