nginx+resin session同步
nginx_upstream_jvm_route解决 session 不同步问题，不过他不是共享，也不是同步，而是通过 cookie_session 来判别！
测试环境：
server1 服务器上安装了 nginx + resin
server2 服务器上只安装了resin
server1 IP 地址： 192.168.6.121
server2 IP 地址： 192.168.6.162
安装步骤：
1. 在server1 上安装配置 nginx +nginx_upstream_jvm_route
shell $> wget -chttp://sysoev.ru/nginx/nginx-0.7.61.tar.gz
shell $>svn checkouthttp://nginx-upstream-jvm-route.googlecode.com/svn/trunk/nginx-upstream-jvm-route-read-only
shell $> tar zxvf nginx-0.7.61
shell $> cd nginx-0.7.61
shell $> patch-p0 < ../nginx-upstream-jvm-route-read-only/jvm_route.patch
shell $> useradd www
shell $> ./configure --user=www--group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module--with-http_ssl_module --add-module=/root/nginx-upstream-jvm-route-read-only
shell $> make
shell $> make install
2.分别在两台机器上安装 resin
### 修改环境变量###
shell $> vim /etc/profile
###在 umask 022 下填加以下###
JAVA_HOME=/usr/lib/jvm/java-6-sun
export JAVA_HOME
JRE_HOME="${JAVA_HOME}"/jre
export JRE_HOME
CLASSPATH=.:"${JAVA_HOME}"/lib/tools.jar:"${JAVA_HOME}"/lib/dt.jar${RESIN_HOME}"/lib/resin.jar:"${CLASSPATH}
export CLASSPATH
RESIN_HOME=/usr/local/resin
export RESIN_HOME
PATH="${JAVA_HOME}"/bin:"${PATH}"
export PATH
shell $> wget -chttp://www.caucho.com/download/resin-3.1.9.tar.gz
shell $> tar zxvf resin-3.1.9.tar.gz
shell $> cd resin-3.1.9
shell $> ./configure --prefix=/usr/local/resin
shell $> make
shell $> make install
3. 配置两台机器的 resin
shell $> cd /usr/local/resin
shell $> cd conf
shell $> vim resin.conf
## 查找 <httpaddress="*" port="8080"/>
## 注释掉 <!--http address="*"port="8080"/-->
## 查找 <server id="" address="127.0.0.1"port="6800">
## 替换成
<server id="a"address="192.168.6.121" port="6800">
<!-- server2address=192.168.6.162 -->
<http id="" port="8080"/>
</server>
<serverid="b" address="192.168.6.121" port="6801">
<!-- server2address=192.168.6.162 -->
<http id="" port="8081"/>
</server>
shell $> cd/usr/local/resin/webapps/ROOT/
shell $> mv index.jsp index.jsp.bak
shell $> vim index.jsp
## 填入以下内容
<%@ page language="java"import="java.util.*" pageEncoding="UTF-8"%>
<%
%>
<html>
<head>
</head>
<body>
121
<!--server2 这里为 162 -->
<br />
<%out.print(request.getSession());%>
<!--输出session-->
<br />
<%out.println(request.getHeader("Cookie")); %>
<!--输出Cookie-->
</body>
</html>
###重启 resin 服务#####
### server1 服务器#####
shell $> /usr/local/resin/bin/httpd.sh -server a start
###注意如果没修改环境变量会报错
### server2 服务器 ####
shell $> /usr/local/resin/bin/httpd.sh -server b start
### 注意的是 server2 服务器只启动 server_id b ###
4.整合 ngxin resin
shell $> cd /usr/local/nginx/conf
shell $> mv nginx.conf nginx.bak
shell $> vim nginx.conf
## 以下是配置 ###
user www www;
worker_processes 4;
error_log logs/nginx_error.log crit;
pid /usr/local/nginx/nginx.pid;
#Specifies the value for maximum file descriptors thatcan be opened by this process.

}
http
{

#### 这里 srun_id=a 对应的是 server1 resin 配置里的 server id="a"
server 192.168.6.162:8081 srun_id=b;
#### 这里 srun_id=b 对应的是 server2 resin 配置里的 server id="b"

}
5.测试，打开浏览器，输入http://192.168.6.121/index.jsp
