* tomcat1 192.168.10.153
* tomcat2 192.168.10.154
Tomcat 工作模式必须为Nio 模式。
##添加如下内容， 注意更换 address="192.168.10.154" 为本机IP
vim /usr/local/tomcat/conf/server.xml

channelSendOptions="8">
<Manager className="org.apache.catalina.ha.session.DeltaManager"

</Cluster>
## 修改 web文件，在</web-app> 上面 添加一行内容
vim /usr/local/tomcat/webapps/ROOT/WEB-INF/web.xml
<distributable/>
##添加测试文件
vim index.jsp
<%@ page contentType="text/html; charset=GBK" %>
<%@ page import="java.util.*" %>
<html>
<head>
<title>Cluster App Test</title>
</head>
<body>
Server Info: <% out.println(request.getLocalAddr() + " : " + request.getLocalPort()+"
");%>
<%
out.println("
ID " + session.getId()+"
"); // 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);
}
%>
</body>
</html>
##配置 nginx负责均衡，进行测试
upstream tomcatserver {
server 192.168.10.153:8080 weight=5;
server 192.168.10.154:8080 weight=5;
}
location / {
proxy_pass http://tomcatserver; #来自jsp请求交给tomcat处理
}
