配置信息
在同一台服务器上使用nginx做反向代理与两个tomcat组成简易tomcat集群
使用
nginx端口80
tomcat1端口21005,21080,21009
tomcat2端口22005,22080,22009
配置过程
1. 先下载apache-tomcat-9.0.78，解压到两个目录，分别为tomcat1和tomcat2
根据上方配置信息分别对两个目录中的/conf/server.xml进行修改
<Resource name="bean/redisson"
auth="Container"
factory="org.redisson.JndiRedissonFactory"
configPath="${catalina.base}/conf/redisson.yaml"
closeMethod="shutdown"/>
配置session共享部分，修改/conf/context.xml
<Context>
<ResourceLink name="bean/redisson"
global="bean/redisson"
type="org.redisson.api.RedissonClient" />
<Manager className="org.redisson.tomcat.JndiRedissonSessionManager"
readMode="REDIS"
jndiName="bean/redisson" />
</Context>
在/conf/目录中添加 redisson.yaml配置文件（更多配置可以参考 https://github.com/redisson/redisson/wiki/2.-Configuration）
singleServerConfig:
idleConnectionTimeout: 10000
connectTimeout: 10000
timeout: 3000
retryAttempts: 3
retryInterval: 1500
password: null
subscriptionsPerConnection: 5
clientName: null
address: "redis://127.0.0.1:6379"
subscriptionConnectionMinimumIdleSize: 1
subscriptionConnectionPoolSize: 50
connectionMinimumIdleSize: 24
connectionPoolSize: 64
database: 0
dnsMonitoringInterval: 5000
threads: 16
nettyThreads: 32
codec: !<org.redisson.codec.MarshallingCodec> {}
transportMode: "NIO"
下载redisson-tomcat-9-3.23.2.jar, redisson-all-3.23.2.jar至/tomcat/lib内
2. 部署nginx，修改/conf/nginx.conf配置文件
3. 安装配置redis，下载后启动
4. 部署测试页面
/tomcat1/webapps/ROOT/index.jsp
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta charset="UTF-8" />
<%
request.getSession().setAttribute("ss1", "ss111");
%>
</head>
<body>
<table align="center" border="1">
<tr>
<td>cluster-desc1</td>
<td>This is the first tomcat</td>
</tr>
<tr>
<td>SessionID</td>
<td><%= request.getSession().getId() %></td>
</tr>
<tr>
<td>SessionCreatedTime</td>
<td><%= request.getSession().getCreationTime() %></td>
</tr>
<tr>
<td>ServerName</td>
<td><%=request.getServerName()%></td>
</tr>
<tr>
<td>SessionPort</td>
<td><%=request.getServerPort()%></td>
</tr>
<tr>
<td>ss1</td>
<td><%=request.getSession().getAttribute("ss1") %></td>
</tr>
<tr>
<td>ss2</td>
<td><%=request.getSession().getAttribute("ss2") %></td>
</tr>
</table>
</body>
</html>
/tomcat2/webapps/ROOT/index.jsp
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta charset="UTF-8" />
<%
request.getSession().setAttribute("ss2", "ss222");
%>
</head>
<body>
<table align="center" border="1">
<tr>
<td>cluster-desc2</td>
<td>This is the first tomcat</td>
</tr>
<tr>
<td>SessionID</td>
<td><%= request.getSession().getId() %></td>
</tr>
<tr>
<td>SessionCreatedTime</td>
<td><%= request.getSession().getCreationTime() %></td>
</tr>
<tr>
<td>ServerName</td>
<td><%=request.getServerName()%></td>
</tr>
<tr>
<td>SessionPort</td>
<td><%=request.getServerPort()%></td>
</tr>
<tr>
<td>ss1</td>
<td><%=request.getSession().getAttribute("ss1") %></td>
</tr>
<tr>
<td>ss2</td>
<td><%=request.getSession().getAttribute("ss2") %></td>
</tr>
</table>
</body>
</html>
5.启动redisson,tomcat1,tomcat2,nginx后访问http://127.0.0.1:21080/index.jsp,http://127.0.0.1:22080/index.js,phttp://127.0.0.1:80/index.jsp能够访问到相应内容，sessionId相同
redisson /redis-server.exe
tomcat /bin/startup.bat
nginx /start nginx
6.程序下载
