nginx+tomcat+memcached的session共享
Memcached安装
下载memcached所需关联包libevent
wget http://www.monkey.org/~provos/libevent-1.2.tar.gz
安装：
tar fvxz libevent-1.2.tar.gz
cd libevent-1.2
./configure �Cprefix=/usr
make
make install
测试libevent是否安装成功
ls �Cal /usr/lib |grep libevent
安装memcached
wget http://www.danga.com/memcached/dist/memcached-1.2.0.tar.gz
tar fvxz memcached-1.2.0.tar.gz
cd memcached-1.2.0
./configure �Cprefix=/usr
make
make install
测试是否安装成功
ls �Cal /usr/local/bin/mem*
启动memcached
/usr/local/bin/memcached �Cd �Cm 10 �Cc 256 �Curoot
连接memcached
telnet IP地址 11211 （memcached默认端口）

JDK 1.7.0_25安装
Mkdir/usr/java/
Tar fvxz jdk-7u25-linux-x64.tar.gz�CC /usr/java
Vim/root/.bash_profile
ll/usr/java看jdk版本
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
exit
java �Cversion
Tomcat 7.0.42安装
Tar fvxz apache-tomcat-7.0.42.tar.gz�CC /usr/local
Cd/usr/local
Mv apache-tomcat-7.0.42tomcat
Nginx 1.5.1安装
yum �Cyinstall gcc*
yum �Cyinstall make*
解压 tar fvxz nginx-1.5.1.tar.gz
./configure�Cprefix=/usr/local/nginx
Yum �Cyinstall pcre-devel
Yum �Cyinstall zlib-devel
./configure�Cprefix=/usr/local/nginx
Make makeinstall
/usr/local/nginx/sbin/nginx
Lsof �Ci:80
配置Nginx
添加参数：

proxy_connect_timeout 5;
proxy_read_timeout 60;
proxy_send_timeout 5;
proxy_buffer_size 16k;

}
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</Context>段内添加
<ManagerclassName="de.javakaffee.web.msm.MemcachedBackupSessionManager"
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()%>
<BR>
SessionIP:<%=request.getServerName()%>
<BR>
SessionPort:<%=request.getServerPort()%>
<%
out.println("Thisis Tomcat Server 111111！");
%>
第二台
SessionID:<%=session.getId()%>
<BR>
SessionIP:<%=request.getServerName()%>
<BR>
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
