apache2.2+tomcat7.0.53+ehcache1.5分布式缓存集群配置完整版

一、环境：

web服务器：tomcat7.0.53

操作系统：window server2008

负载均衡：apache2.2（mod_jk模块）

缓存：ehcache1.5.0

二、安装：

1.先将apache2.2安装在31.0.240.54，下载好安装包后开始安装。

有疑问可以参考/article/10174687.html

2.准备好java运行环境后分别将tomcat7.0.53解压出来放在机器31.0.240.55和31.0.240.56磁盘固定位置，确保各自可以正常运行。

3.开始安装在apache上安装mod_jk模块，apache2.2默认已经有mod_jk.so模块了，但是不影响我们采用单独的模块tomcat-connectors-1.2.40-windows-i386-httpd-2.2.x.zip中的mod_jk来工作。可以去官网下载，目前可以到此处下载http://www.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/windows/

注释：在这里解释下，据我了解apache做负载均衡可以有两种方式：mod_proxy和mod_jk。其中mod_proxy是apache自己支持的方式，其中mod_jk分为1和2两个版本，据闻版本2不够稳定，问题多多，不建议使用。

mod_proxy

优势:

不需要编译和维护一个对立的模块。mod_proxy,mod_proxy_http,mod_proxy_ajp,mod_proxy_balancer已经是apache 2.2+的标准集成部分；

可以使用http、https和AJP协议，即便是在同一个balancer中。

劣势:

mod_proxy_ajp不支持大于8k的数据包；

只有最基本的负载均衡器；

不支持域模型集群（domain model clustering）

mod_jk

优势:

先进的负载均衡器；

先进的节点失败侦察功能；

支持大型AJP 数据包

劣势:

需要单独维护一个独立的模块；

4.将准备好的mod_jk.so文件改名为mod_jk_http2.so并复制到 Apache 安装目录下的 modules 子目录中。里面已经有了一个mod_jk.so，可以不予理睬，使用jk需要几个文件，分别是mod_jk.conf和workers.properties以及uriworkermap.properties。

先修改httpd.conf文件，进入 Apache 安装目录下的 conf 子目录中，打开 httpd.conf 配置文件，在最后插入以下一行： Include conf/mod_jk.conf。

下面介绍其他几个文件：

mod_jk.conf内容如下：

# Load mod_jk module. Specify the filename
# of the mod_jk lib you’ve downloaded and
# installed in the previous section
# 加载 mod_jk 模块
LoadModule jk_module modules/mod_jk_http2.so
# Where to find workers.properties
JkWorkersFile conf/workers.properties
JkMountFile conf/uriworkermap.properties
# Where to put jk logsJkLogFile logs/mod_jk.log
# Set the jk log level [debug/error/info]JkLogLevel info
# Select the log format#JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
# JkOptions indicate to send SSL KEY SIZE
# JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
# JkRequestLogFormat set the request format
#JkRequestLogFormat "%w %V %T"

workers.properties内容如下：

#========loadbalancer,负载均衡控制器========    
worker.list=loadbalancer

#========node1========    
worker.node1.port=8009          
#ajp13 端口号，在tomcat下server.xml配  置,默认8009    
worker.node1.host=31.0.240.55   
#tomcat的主机地址，如不为本机，请填写ip地址    
worker.node1.type=ajp13
worker.node1.connection_pool_size=400
worker.node1.connection_pool_minsize=100
worker.node1.lbfactor = 1     
#server的加权比重，值越高，分得的请求越多    
  
#========node2========    
worker.node2.port=8009         
#ajp13 端口号，在tomcat下server.xml配置,    
worker.node2.host=31.0.240.56   
#tomcat的主机地址，如不为本机，请填写ip地址    
worker.node2.type=ajp13   
worker.node2.connection_pool_size=400
worker.node2.connection_pool_minsize=100
worker.node2.lbfactor = 1     
#server的加权比重，值越高，分得的请求越多  

worker.loadbalancer.type=lb  
worker.loadbalancer.balance_workers=node1,node2 
#指定分担请求的tomcat
worker.loadbalancer.retries=3  
#重试次数 
worker.loadbalancer.sticky_session=false  
#配置session会话是否为粘性   
#此处指定集群是否需要会话复制，如果设为 true ，则表明为会话粘性，不进行会话复制，当某用户的请求第一次分发到哪台 Tomcat 后，后继的请求会一直分发到此 Tomcat 服务器上处理；如果设为 false ，则表明需求会话复制。
worker.loadbalancer.sticky_session_force=false 
#如果sticky_session设为true时，此处一般设为false 

uriworkermap.properties内容如下：

#所有请求都由LB_worker这个worker处理
/*=loadbalancer

5.开始配置tomcat集群以及session复制的功能，找到tomcat安装目录的conf目录下server.xml配置文件，31.0.240.55的tomcat修改为以下内容：

注意：在这里我们使用ajp协议进行负载连接，tomcat的session同步功能默认是需要用到组播，windows默认情况下是开通组播服务，网上几乎都是基于这种默认的组播配置，我这里是基于点对点的单播配置，至于区别在这里不做说明。

到目前为止集群配置基本完成，可以启动运行去测试一下了，测试可以使用一个空白的web项目，然后更改index.jsp的内容即可，内容如下：

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page import="java.text.SimpleDateFormat"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>TestCluster</title>
</head>
<body>
Server Info:
<%
String dtm = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").format(new Date());
System.out.println("["+request.getLocalAddr()+":"+ request.getLocalPort()+"]" + dtm);
out.println("<br>["+request.getLocalAddr()+":" +request.getLocalPort()+"]" + dtm+"<br>");
%>
Session Info:
<%
session.setAttribute("name","dennisit");
System.out.println("[Session Info] Session ID:"+session.getId());
out.println("<br>[Session Info] Session ID:" + session.getId()+"<br>");
%>
</body>
</html>

当我们打开浏览器查看的时候可以发现类似这样的结果：

Server Info:

[31.0.240.55:80]2014-05-26 09:36:14

Session Info:

[Session Info] Session ID:14C262DC317EBD7AD2F07C9B23DDFCAC.node1

以及

Server Info:

[31.0.240.55:80]2014-05-26 09:36:14

Session Info:

[Session Info] Session ID:14C262DC317EBD7AD2F07C9B23DDFCAC.node2

注意：如果后面的node1和node2始终不变需要确认下workers.properties中的session是否黏性。如果是非黏性可能还是会出现后面的node1和node2不变，但可以注意后台，其实已经是负载均衡了。至于要切换可能需要再做一些额外的配置，在tomcat的server.xml需要配置org.apache.catalina.ha.session.JvmRouteBinderValve这有可能会造成session有一定的问题，所以要慎用了。

6.下面进行ehcache分布式缓存配置：

在项目所在的class文件夹下找到ehcache.xml文件，(使用单播方式)示例如下：

31.0.240.55上应用的配置：

<ehcache>

<diskStore path="java.io.tmpdir"/>

<defaultCache maxElementsInMemory="10000" eternal="false"
timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true"

</cache>

<cache name="org.hibernate.cache.UpdateTimestampsCache"
maxElementsInMemory="10000" eternal="false" overflowToDisk="true"
timeToIdleSeconds="300" timeToLiveSeconds="600"

</cache>

<cache name="org.hibernate.cache.StandardQueryCache"
maxElementsInMemory="10000" eternal="false" overflowToDisk="true"
timeToIdleSeconds="300" timeToLiveSeconds="600"
memoryStoreEvictionPolicy="LFU">
<cacheEventListenerFactory class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"
properties="replicateAsynchronously=false, replicatePuts=true, replicateUpdates=true,replicateUpdatesViaCopy= true, replicateRemovals=true"/>
</cache>

<cacheManagerPeerListenerFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
properties="hostName=31.0.240.55,port=4080,socketTimeoutMillis=8000" />

<cacheManagerPeerProviderFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=manual,rmiUrls=//31.0.240.56:4080/defaultCacheDefine|//31.0.240.56:4080/org.hibernate.cache.UpdateTimestampsCache|//31.0.240.56:4080/org.hibernate.cache.StandardQueryCache" />

<!--
<cacheManagerPeerProviderFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=automatic, multicastGroupAddress=31.0.240.55,
multicastGroupPort=40802, timeToLive=32" />

<cacheManagerPeerProviderFactory

<cacheManagerPeerListenerFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
properties="hostName=localhost,socketTimeoutMillis=2000"/>-->

</ehcache>

31.0.240.56上应用配置如下：

<ehcache>

<diskStore path="java.io.tmpdir"/>

<defaultCache maxElementsInMemory="10000" eternal="false"
timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true"

</cache>

<cache name="org.hibernate.cache.StandardQueryCache"
maxElementsInMemory="10000" eternal="false" overflowToDisk="true"

配置完成。

三、优化

1.ehcache缓存的配置也可以参考我的上一篇帖子：/article/10174686.html，在这里并没有关于性能参数的配置。包括apache和tomcat的连接数设置等，

2.关于apache的性能优化参考：/article/10174688.html

3.关于tomcat的性能优化参考：/article/10174690.html
