linux+nginx+tomcat負載均衡，實現(xiàn)session同步

阿里云服務器優(yōu)惠券

花了一個上午的時間研究nginx+tomcat的負載均衡測試，集群環(huán)境搭建比較順利，但是session同步的問題折騰了幾個小時才搞定，現(xiàn)把我的過程貼上來，以備用。
軟件及環(huán)境是：
虛擬機上裝centos 5.5
IP為：192.168.0.51 裝上nginx和tomcat 6.0.32 命名為 Tomcat1
一臺win7上裝tomcat 6.0.32 IP為：192.168.0.50 命名為 Tomcat2

首先裝nginx，我是參照http://blog.s135.com/nginx_php_v6/ 配了一個Nginx + PHP（FastCGI）環(huán)境，然后再加上Tomcat的轉發(fā)。
我的nginx.conf 修改如下

下一步是配置Tomcat集群。分別打開tomcat1和tomcat2下conf中server.xml
<Server port="8005" shutdown="SHUTDOWN">

<Connector port="8080" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />

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

找到<Engine name="Catalina" defaultHost="localhost">
Tomcat1下的修改為<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">
Tomcat2下的修改為<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2">

tomcat1找到
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>
修改為

channelSendOptions="6">

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

expireSessionsOnShutdown="false"

notifyListenersOnReplication="true"/>

tomcat2找到

channelSendOptions="6">

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

expireSessionsOnShutdown="false"

notifyListenersOnReplication="true"/>

<!--

-->

<Channel className="org.apache.catalina.tribes.group.GroupChannel">

dropTime="3000"/>

<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"

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.MessageDispatch15Interceptor"/>

</Channel>

<Valve className="org.apache.catalina.ha.tcp.ReplicationValve" filter=".*\.gif;.*\.js;.*\.jpg;.*\.png;.*\.htm;.*\.html;.*\.css;.*\.txt;"/>

<ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>

<ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>

</Cluster>

還需要在程序的web.xml里面</web-app>前面加入以下這句話
<distributable/>
session同步到這里設置完畢

服務器的啟動順序如下:
tomcat1 --> |tomcat2 --> |nginx

先啟動tocmat1,等tomcat1啟動完全的時候再啟動tomcat2，等兩個tocmat全啟動之后，再啟動nginx

負載的時候可以用APACHE或NGINX，如果什么都不用，兩臺一接防問了話，可能會出錯極session不同步的問題，網(wǎng)上也很多人介意不要做seeeion同步，這樣會降低機器的性能，有一個方法可以，就是NGINX的ip_hash,這樣至少可以保證客戶端去防問同一臺TOCMAT，除非那臺TOCMAT掛了

不錯，還可以考慮使用memcache存儲Session 回復更多評論

一、下載下列幾個 Jar包
http://memcached-session-manager.googlecode.com/files/memcached-session-manager-1.3.0.jar
http://memcached-session-manager.googlecode.com/files/msm-javolution-serializer-jodatime-1.3.0.jar
http://memcached-session-manager.googlecode.com/files/msm-javolution-serializer-cglib-1.3.0.jar
http://spymemcached.googlecode.com/files/memcached-2.4.2.jar
http://memcached-session-manager.googlecode.com/files/javolution-5.4.3.1.jar

將以下幾個Jar包Copy到 $TOMCAT_HOME/lib目下，每個Tomcat節(jié)點都需要有。

二、配置Tomcat的Server.xml配置文件，樣本可以點擊這里下載，主要內(nèi)容如下：
http://www.javabloger.com/images/2010-05/webcluster/server.xml.txt

<Context docBase="D:\webapp" path="" reloadable="true" >
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
memcachedNodes="n1:localhost:11211"
requestUriIgnorePattern=".*\.(png|gif|jpg|css|js)$"
sessionBackupAsync="false"
sessionBackupTimeout="100"
transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"
copyCollectionsForSerialization="false"
/>
</Context>

每個Tomcat的節(jié)點都需要修改。
