tomcat自带session共享功能不必非集成第三方软件只需配置即可 http://tomcat.apache.org/tomcat-8.5-doc/cluster-howto.html

为什么选择Nginx？

Nginx 是一个很强大的高性能Web和反向代理服务器，它具有很多非常优越的特性：
在连接高并发的情况下，Nginx是Apache服务器不错的替代品：Nginx在美国是做虚拟主机生意的老板们经常选择的软件平台之一。能够支持高达 50,000 个并发连接数的响应，感谢Nginx为我们选择了 epoll and kqueue作为开发模型。

配置结构图

1、下载地址

http://nginx.org/en/download.html ，这里我们推荐下载稳定版（stable versions），本文采用nginx/Windows-1.12.0。

2、目录结构

Nginx 命令

start nginx
nginx -s stop
nginx -s quit

3、nginx.conf配置

Nginx配置文件默认在conf目录，主要配置文件为nginx.conf

#user  nobody;worker_processes  1;#error_log  logs/error.log;#error_log  logs/error.log  notice;#error_log  logs/error.log  info;#pid        logs/nginx.pid;events {    worker_connections  1024;}http {    include       mime.types;    default_type  application/octet-stream;    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '    #                  '$status $body_bytes_sent "$http_referer" '    #                  '"$http_user_agent" "$http_x_forwarded_for"';    #access_log  logs/access.log  main;    sendfile        on;    #tcp_nopush     on;    #keepalive_timeout  0;    keepalive_timeout  65;    #gzip  on;upstream suroot{        server 127.0.0.1:8090 max_fails=2 fail_timeout=30s;        server 127.0.0.1:9091 max_fails=2 fail_timeout=30s;    }    server {        listen       80;        server_name  localhost;        #charset koi8-r;        #access_log  logs/host.access.log  main;        location / {root   html;index  index.html index.htm index.jsp login.jsp; #定义首页索引文件的名称proxy_pass http://suroot/;#请求转向suroot定义的服务器列表#以下是一些反向代理的配置可删除.proxy_redirect off;proxy_set_header   Host $host;proxy_set_header   X-Real-IP $remote_addr;proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;client_max_body_size   10m;#允许客户端请求的最大单文件字节数client_body_buffer_size   128k;#缓冲区代理缓冲用户端请求的最大字节数，proxy_connect_timeout   600;#nginx跟后端服务器连接超时时间(代理连接超时)proxy_send_timeout   600; #后端服务器数据回传时间(代理发送超时)proxy_read_timeout   600; #连接成功后，后端服务器响应时间(代理接收超时)proxy_buffer_size   8k; #设置代理服务器（nginx）保存用户头信息的缓冲区大小proxy_buffers   4 64k;#proxy_buffers缓冲区，网页平均在32k以下的话，这样设置proxy_busy_buffers_size   128k;#高负荷下缓冲大小（proxy_buffers*2）proxy_temp_file_write_size  128k;#设定缓存文件夹大小，大于这个值，将从upstream服务器传        }        #error_page  404              /404.html;        # redirect server error pages to the static page /50x.html        #        error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }        # proxy the PHP scripts to Apache listening on 127.0.0.1:80        #        #location ~ \.php$ {        #    proxy_pass   http://127.0.0.1;        #}        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000        #        #location ~ \.php$ {        #    root           html;        #    fastcgi_pass   127.0.0.1:9000;        #    fastcgi_index  index.php;        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;        #    include        fastcgi_params;        #}        # deny access to .htaccess files, if Apache's document root        # concurs with nginx's one        #        #location ~ /\.ht {        #    deny  all;        #}    }    # another virtual host using mix of IP-, name-, and port-based configuration    #    #server {    #    listen       8000;    #    listen       somename:8080;    #    server_name  somename  alias  another.alias;    #    location / {    #        root   html;    #        index  index.html index.htm;    #    }    #}    # HTTPS server    #    #server {    #    listen       443 ssl;    #    server_name  localhost;    #    ssl_certificate      cert.pem;    #    ssl_certificate_key  cert.key;    #    ssl_session_cache    shared:SSL:1m;    #    ssl_session_timeout  5m;    #    ssl_ciphers  HIGH:!aNULL:!MD5;    #    ssl_prefer_server_ciphers  on;    #    location / {    #        root   html;    #        index  index.html index.htm;    #    }    #}}

4、Tomcat配置

对于tomcat大家都很熟悉，只需要修改server.xml配置文件即可;

这里我们以apache-tomcat-8.5.5为例，分别在server目录，解压缩并命名为：apache-tomcat-8.5.5-8090、apache-tomcat-8.5.5-8091

第一处端口修改：
Xml代码 :

<!--  修改port端口：8006 俩个tomcat不能重复，端口随意，别太小-->  <Server port="8006" shutdown="SHUTDOWN">

第二处端口修改：
Xml代码 :

<!-- port="8090" tomcat监听端口，随意设置，别太小 -->  <Connector port="8090" protocol="HTTP/1.1"                  connectionTimeout="20000"                  redirectPort="8443" />

第三处端口修改：

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

第四处session共享配置

      <!--      <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>      -->        <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"                 channelSendOptions="6">          <Manager className="org.apache.catalina.ha.session.BackupManager"                   expireSessionsOnShutdown="false"                   notifyListenersOnReplication="true"                   mapSendOptions="6"/>          <!--          <Manager className="org.apache.catalina.ha.session.DeltaManager"                   expireSessionsOnShutdown="false"                   notifyListenersOnReplication="true"/>          -->          <Channel className="org.apache.catalina.tribes.group.GroupChannel">            <Membership className="org.apache.catalina.tribes.membership.McastService"                        address="228.0.0.4"                        port="45564"                        frequency="500"                        dropTime="3000"/>            <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"                      address="auto"                      port="5000"                      selectorTimeout="100"                      maxThreads="6"/>            <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">              <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>            </Sender>            <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>            <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatchInterceptor"/>            <Interceptor className="org.apache.catalina.tribes.group.interceptors.ThroughputInterceptor"/>          </Channel>          <Valve className="org.apache.catalina.ha.tcp.ReplicationValve"                 filter=".*\.gif|.*\.js|.*\.jpeg|.*\.jpg|.*\.png|.*\.htm|.*\.html|.*\.css|.*\.txt"/>          <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"                    tempDir="/tmp/war-temp/"                    deployDir="/tmp/war-deploy/"                    watchDir="/tmp/war-listen/"                    watchEnabled="false"/>          <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>        </Cluster>

其次验证tomcat，启动两个tomcat，不出现端口冲突即为成功。

java项目web.xml需要配置加入

<distributable/>

验证页面session是否相同

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%  String path = request.getContextPath();  String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head>  <base href="<%=basePath%>">  <title>My JSP 'index.jsp' starting page</title>  <meta http-equiv="pragma" content="no-cache">  <meta http-equiv="cache-control" content="no-cache">  <meta http-equiv="expires" content="0">  <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">  <meta http-equiv="description" content="This is my page">  <!--  <link rel="stylesheet" type="text/css" href="styles.css">  --></head><body>  SessionID:<%=session.getId()%>  <BR>  SessionIP:<%=request.getServerName()%>  <BR>  SessionPort:<%=request.getServerPort()%>  <%    out.println("This is Tomcat Server 11111");  %></body></html>
