将其它注释

添加三条变量

vim/root/.bash_profile

exportJAVA_HOME=/usr/java/jdk1.7.0版本对应

exportPATH=$PATH:$JAVA_HOME/bin

exportCLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar

yum –yinstall make*

解压 tar fvxz nginx-1.5.1.tar.gz

./configure–prefix=/usr/local/nginx

Yum –yinstall pcre-devel

Yum –yinstall zlib-devel

./configure–prefix=/usr/local/nginx

在http://code.google.com/p/memcached-session-manager/downloads/list网站下载memcached所需的jar包放在tomcat/lib下

memcached-2.6.jar

memcached-session-manager-1.5.1.jar

memcached-session-manager-tc7-1.5.1.jar

msm-javolution-serializer-1.5.1.jar

msm-kryo-serializer-1.5.1.jar

msm-xstream-serializer-1.5.1.jar

在http://memcached-session-manager.googlecode.com/files/javolution-5.4.3.1.jar下载

Javolution-5.4.3.1.jar


在tomcat的/usr/local/tomcat/conf/context.xml内的段内添加

  memcachedNodes="n1:localhost:11211"

   requestUriIgnorePattern=".*\.(png|gif|jpg|css|js)$"

   sessionBackupAsync="false"

   sessionBackupTimeout="100"

  copyCollectionsForSerialization="false"

  transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"/>

memcachedNodes=配置memcached的节点多个memcached用，分开。Localhost改成memcached所在的IP地址。


两台tomcat必须都下载jar包和添加以上内容


测试nginx+tomcat+memcached的session共享

在两台tomcat的/webapps/Root内写测试页test.jsp

第一台

SessionID:<%=session.getId()%>


SessionIP:<%=request.getServerName()%>


SessionPort:<%=request.getServerPort()%>

<%

out.println("Thisis Tomcat Server 111111！");

%>


第二台

SessionID:<%=session.getId()%>


SessionIP:<%=request.getServerName()%>


SessionPort:<%=request.getServerPort()%>

<%

out.println("Thisis Tomcat Server 222222！");

%>


打开网页访问nginx

zkx.9anbi.com/test.jsp

反复刷新页面，如果sessionID一直不变，下面的sessionPort的内容不断变化则说明配置成功
