软件及环境:
jboss-5.1.0.GA
nginx-0.8.15
centos5.5
nginx:192.168.1.251
tomat1:192.168.1.251
tomat2:192.168.1.252
jboss安装目录为:/usr/local/jboss
nginx安装目录为:/usr/local/nginx
JDK、JBOSS、nginx安装略过！
Jboss1配置：
/opt/jboss4.3/jboss-as/server/node2/deploy/jboss-web.deployer/server.xml
<!--由于在LINUX环境下，会有多个IP，address不能改成${0.0.0.0}，这样会对127.0.0.1也会进行监听，导致启动出错-->
<Connector protocol="HTTP/1.1" port="8080" address="${ jboss.bind.address}">
<!--将<Engine name="jboss.web" defaultHost="localhost">修改为-->
<Engine name="jboss.web" defaultHost="localhost" jvmRoute="jboss1">
/opt/jboss4.3/jboss-as/server/node2/deploy/jboss-messaging.sar/messaging-service.xml
<!--将20行的<attribute name="ServerPeerID">${jboss.messaging.ServerPeerID:0}</attribute>修改-->
<attribute name="ServerPeerID">${jboss.messaging.ServerPeerID:1}</attribute>
Jboss2配置：
/opt/jboss4.3/jboss-as/server/node2/deploy/jboss-web.deployer/server.xml
<!--由于在LINUX环境下，会有多个IP，address不能改成${0.0.0.0}，这样会对127.0.0.1也会进行监听，导致启动出错-->
<Connector protocol="HTTP/1.1" port="8080" address="${ jboss.bind.address}">
<!--将<Engine name="jboss.web" defaultHost="localhost">修改为-->
<Engine name="jboss.web" defaultHost="localhost" jvmRoute="jboss2">
/opt/jboss4.3/jboss-as/server/node2/deploy/jboss-messaging.sar/messaging-service.xml
<!--将20行的<attribute name="ServerPeerID">${jboss.messaging.ServerPeerID:0}</attribute>修改-->
<attribute name="ServerPeerID">${jboss.messaging.ServerPeerID:2}</attribute>
如果想要session同步的话，要在站点的web.xml里面加入<distributable/>
测试文件index.jsp内容如下：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@page import="java.util.*"%>
<%@page import="java.net.InetAddress;"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Cluster App Test</title>
</head>
<body>
<%
InetAddress ip = InetAddress.getLocalHost();
//out.println(ip.getHostAddress());
%>
This is responsed by <font color="red"> <%=ip.getHostAddress() %></font><br>
Host Name : <font color="red"><%=ip.getHostName() %></font><br>
Time : <font color="red"><%=new Date() %></font><br>
<%
ip = null;
%>
<br/> <br/> <br/> <br/>
Server Info:
<%
out.println(request.getLocalAddr() + " : " + request.getLocalPort()+"<br>");%>
<%
out.println("<br>Session ID " + session.getId()+"<br>");
// 如果有新的 Session 属性设置
String dataName = request.getParameter("dataName");
if (dataName != null && dataName.length() > 0) {
String dataValue = request.getParameter("dataValue");
session.setAttribute(dataName, dataValue);
}
out.print("<br/> <b>Session 列表</b>");
Enumeration e = session.getAttributeNames();
while (e.hasMoreElements()) {
String name = (String)e.nextElement();
String value = session.getAttribute(name).toString();
out.println( name + " = " + value+"<br>");
System.out.println( name + " = " + value);
}
%>
<form action="index.jsp" method="POST">
名称:<input type=text size=20 name="dataName">
<br>
值:<input type=text size=20 name="dataValue">
<br>
<input type=submit>
</form>
</body>
</html>
Jboss动好像没什么要求，，可以两个同时启动，等启动完之后再启动NGINX就OK了！
Jboss的启动命令为（必须加参数-b ，很多配置文件都依赖于
${ jboss.bind.address}这个值，也就是命令行输入的IP地址）：
/usr/local/jboss/bin/run.sh -c all -b 192.168.1.251
等都启动完成，就可以防问http://192.168.1.251/cluster-test/
写一个session，刷新，如果session在不同的机器上保持不变，那就集成功了！如下图:
