nfserver.xml,修改內容如下
將集羣配置選項的註釋放開即可，如上。

(3)在Conf目錄下建立jk2.properties文件，寫入下面一行，其中端口爲相應的Tomcat對應的AJP端口。
channelSocket.port=8009)分別修改三個tomcat的配置文件co
(4)重啓三個tomcat。到此tomcat的集羣已配置完成。

修改前   (五)應用配置
對於要進行負載和集羣的的tomcat目錄下的webapps中的應用中的WEB-INF中的web.xml文件要添加如下一句配置
<distributable/>配置的條件下配置tomcat集羣 (2
配置前

(四)tomcat集羣配置(1)負載均衡 <?xml version="1.0" encoding="UTF-8"?>
