nginx 解决session共享问题(jvm-route)方式

1.下载安装jvm_route:http ://nginx-upstream-jvm-route.googlecode.com/svn/trunk/nginx-upstream-jvm-route-read-only
 cd /usr/src/nginx-1.2.1
 patch - p0  < /usr/local/nginx/nginx_upstream-jvm-route-read-only/jvm_route.patch
 ./configure --add-module=/usr/local/nginx/nginx-upstream-jvm-route-read-only
 make & make install
2.nginx 设置：
修复 
upstream www.linuxidc.com { 
  server 192.168.1.116:8080 srun_id=a; 
    这里 srun_id=a  对应的是 server1  resin 配置里的 server id="a" 
  server 192.168.1.117:8081 srun_id=b; 
    这里 srun_id=b  对应的是 server2 resin 配置里的 server id="b" 
  jvm_route $cookie_JSESSIONID|sessionid; 
 }
3.tomcat 设置：
 192.168.0.116设置：
 修改tomcat/conf/server.xml
 <Engine name="Catalina" defaultHost="localhost" jvmRoute="a">
 192.168.0.117设置：
 修改tomcat/conf/server.xml
 <Engine name="Catalina" defaultHost="localhost" jvmRoute="b">
