nginx+resin+mysql实现session共享

 

resin 专业版具备http负载均衡的能力，我们这里采用nginx来负载均衡resin的http请求，同时使用jvm做到session共享的效果.

 

一.软件下载
jdk1.6（rpm）
wget https://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_Developer-Site/en_US/-/USD/ViewFilteredProducts-SingleVariationTypeFilter?DLWidget=true&AutoWidgetDL=

nginx&&pcre
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.02.tar.gz
wget http://nginx.org/download/nginx-0.8.34.tar.gz

jvm
wget http://nginx-upstream-jvm-route.googlecode.com/files/nginx-upstream-jvm-route-0.1.tar.gz

resin
wget http://www.caucho.com/download/resin-pro-3.1.10.tar.gz

mysql

wget http://dev.mysql.com/get/Downloads/MySQL-5.1/MySQL-client-community-5.1.46-1.rhel5.i386.rpm/from/http://mysql.mirror.tw/
wget http://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.12.tar.gz/from/http://mysql.stu.edu.tw/
 wget http://dev.mysql.com/get/Downloads/MySQL-5.1/MySQL-server-community-5.1.46-1.rhel5.i386.rpm/from/http://mysql.cs.pu.edu.tw/
 

 

二.安装及初始化
1.安装jdk

cp jdk-6u20-linux-x64-rpm.bin /usr/java
cd /usr/java
./jdk-6u20-linux-x64-rpm.bin ###时间有点长
rpm -ivh jdk-6u20-linux-amd64.rpm
##设置环境变量，
echo -en "export JAVA_HOME = /usr/java/jdk1.6
export PATH = $PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin
exportCLASSPATH=.:/usr/java/jdk1.6/lib:/usr/java/jdk1.6/jre/lib:$CLASSPATH"
>> /etc/profile
source  /etc/profile
java --version
##出现java版本说明安装jdk成功
cd

2.安装jvm&&nginx
tar zxvf pcre-8.02.tar.gz
cd pcre 8.02
./configure
make;make install
cd ..

tar zxvf nginx-0.8.34.tzr.gz
cd ..

tar zxvf  nginx-upstram*
mv nginx-upstram-jvm-route nginx0.8.34
cd nginx-0.8.34
##打补丁
patch -p0 < nginx-upstram-jvm-route/jvm_route.patch
##编译
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --add-module=nginx_upstream_jvm_route
cd ..

3.安装resin
tar zxvf  resin*
cd resin3.1.10
./configure --prefix=/usr/local/resin
make;make install
## 环境变量
echo "export RESIN_HOME=/usr/local/resiin " >> /etc/profile
source /etc/export

 

三.整合
1.配置及启动resin
cd /usr/localresin
vi conf/resin.comf
###查找

###注释掉

###查找

###替换成（3.1版本这个地方进行了改动）

echo "rest" > webapp/ROOT/test.jsp
cp webapp/ROOT/index.jsp /webapp/ROOT/index.jsp_bak
echo > webapp/ROOT/index.jsp

vi webapp/ROOT/index.jsp
###add;( 测试代码来源于互联网)
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
%>

 
   
     
        this is a page
       

       <%out.print(request.getSession()) ;%>
      
       

        <%out.println(request.getHeader("Cookie")); %>
     
     
  ###启动resin
启动server 1：bin/httpd.sh -server 1 start
启动server 2：bin/httpd.sh -server 2 start
启动server 3：bin/httpd.sh -server 3 start
###整合nginx与resin
vi  /usr/local/nginx/conf/nginx.conf
 ###增加如下两段(访问jsp文件则proxy_pass到webgroup群集)
http{
......
   upstream webgroup {
    server 127.0.0.1:8080 srun_id=1; ## 注意与resin server id对应
    server 127.0.0.1:8080 srun_id=2;
    server 127.0.0.1:8080 srun_id=3;
   
    jvm_route $cookie_JSESSIONID|sessionid;
 }
  .....................
server{
   listen       80;
   server_name  127.0.0.1 localhost;
   index index.html index.htm index.jsp;
   root  /usr/local/www;

   location ~ .*\.jsp$
   {
     proxy_pass http://webgroup;
     proxy_redirect    off;
     proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
     proxy_set_header  X-Real-IP  $remote_addr;
     proxy_set_header  Host $http_host;
   }
..........................
}
}

 

###启动nginx
/usr/local/nginx/sbin/nginx

 

四.测试
links 127.0.0.1/test.jsp ###测试resin是否正常
links 127.0.0.1/index.jsp###测试session是否共享
可以使用不同的浏览器进行测试
同一个浏览器数次刷新后看看session id是否变化，如果不变化，说明jvm模块是起了作用的
the end

 

五. 安装mysql

我这里使用rpm包安装，源码编译安装也可，主要就是mysql的jdbc驱动需要设置配置一下

rpm -ivh MySQL-client*

rpm -ivh MySQL-server*

tar zxvf mysql*

cp mysql-connector* /usr/local/resin

cp mysql-connector-java-5.1.12-bin.jar /usr/local/resin/lib

echo "JDBC_HOME=/usr/local/resin/mysql-connector-java-5.1.12" >> /etc/profile

source /etc/profile

###给root授权，注意这里面不能是@localhost，resin调用jdbc类似于远程读取

mysql

GRANT ALL ON *.* TO root@'%';

use test；

create table test（age int not null primary key，name char(20)）;

INSERT INTO test (age,name) values ('20'','admin');

exit

###建立测试页面,读取name数值（测试代码来源于互联网）

 vi  /usr/local/resin/webapps/ROOT/test.jsp

###add;

<%@ page contentType="text/html;charset=GBK" %>
<%@ page language="java" import="java.sql.*"%>
<%
Connection conn = null;
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = java.sql.DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","");
if(conn==null){
System.out.println("get Conn Error");
}
Statement stmt=conn.createStatement();
ResultSet RS_result=null;
%>




<%
RS_result=stmt.executeQuery("select * from test");
String Name;
while(RS_result.next())
{
Name=RS_result.getString("username");
%>
<%=Name%>
<%
}
RS_result.close();
stmt.close();
conn.close();
%>

 

测试结果：

links 127.0.0.1/test.jsp

出现admin即表明测试成功
