一,web服务器小论
  以前的公司使用的web服务器是tomcat(tomcat+apache作集群),现在的公司是一家互联网公司,采用的架构是resin+nginx作集群(resin比tomcat快?还有待以后章节比较讨论),
 
 
集群配置服务器说明:
        1),serve1:127.0.0.1:8080
            2), serve2:127.0.0.1:8081
            3), nginx:127.0.0.1:80
集群配置服务器说明:
        1),serve1:127.0.0.1:8080
            2), serve2:127.0.0.1:8081
            3), nginx:127.0.0.1:80
二,配置resin服务器
  (注:resin4之前,可以搭一个服务器,在<cluster></cluster>中配置多个server实例,通过实例启动,4.0之后就不可以了,要有专业版才能实现)
  在安装resin之前,必须先安装完jvm环境。
  serve1:127.0.0.1:8080--->
      1,安装resin-4.0.*.tar.gz包
- shell $> tar zxvf resin-4.0.23.tar.gz  
- shell $> cd resin-4.0.23 
- shell $> ./configure --prefix=/usr/resin/resinserver1/resinserver1/  
- shell $> make  
- shell $> make install  
shell $> tar zxvf resin-4.0.23.tar.gz shell $> cd resin-4.0.23 shell $> ./configure --prefix=/usr/resin/resinserver1/resinserver1/ shell $> make shell $> make install
   2,配置resin.conf文件
 shell $> cd /usr/resin/resinserver1/resinserver1/
- shell $> cd conf  
- shell $> vim resin.conf  
- ##  查找     <http address="*" 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="resinserver1" address="127.0.0.1" port="6800">  
-      <!--<strong>两台服务器配置不同的watchdog端口,否则会出现异常</strong>-->  
-     <watchdog-port>6700</watchdog-port>  
-     <http id="" port="8080"/>  
-     </server>  
- ###重启  resin 服务#####  
- shell $> cd ../bin  
- shell $>./resin.sh -server resinserver1 start  
shell $> cd conf shell $> vim resin.conf ##  查找     <http address="*" 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="resinserver1" address="127.0.0.1" port="6800">      <!--两台服务器配置不同的watchdog端口,否则会出现异常-->     <watchdog-port>6700</watchdog-port>     <http id="" port="8080"/>     </server> ###重启  resin 服务##### shell $> cd ../bin shell $>./resin.sh -server resinserver1 start 
 serve1:127.0.0.1:8081--->
  ---1,
- shell $> tar zxvf resin-4.0.23.tar.gz  
- shell $> cd resin-4.0.23 
- shell $> ./configure --prefix=/usr/resin/resinserver2/resinserver2/  
- shell $> make  
- shell $> make install  
shell $> tar zxvf resin-4.0.23.tar.gz shell $> cd resin-4.0.23 shell $> ./configure --prefix=/usr/resin/resinserver2/resinserver2/ shell $> make shell $> make install
 2,配置resin
  shell $> cd conf
- shell $> vim resin.conf  
- ##  查找     <http address="*" 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="resinserver2" address="127.0.0.1" port="6801">  
-      <!--两台服务器配置不同的watchdog端口-->  
-     <watchdog-port>6701</watchdog-port>  
-     <http id="" port="8081"/>  
-     </server>  
- ###重启  resin 服务#####  
- shell $> cd ../bin  
- shell $>./resin.sh -server resinserver2 start  
shell $> vim resin.conf ##  查找     <http address="*" 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="resinserver2" address="127.0.0.1" port="6801">      <!--两台服务器配置不同的watchdog端口-->     <watchdog-port>6701</watchdog-port>     <http id="" port="8081"/>     </server> ###重启  resin 服务##### shell $> cd ../bin shell $>./resin.sh -server resinserver2 start
 通过以上配置,开启两台resin服务器,接下来就是配置nginx
 三,nginx的配置
      nginx安装需要以下软件包安装
  1,nginx-1.1.5.tar.gz
      2,tbje-nginx-upstream-jvm-route-6016b39.tar.gz
      3,openssl-1.0.0e.tar.gz(OPENSSL不需要编译安装,只需要解压出来就行)
  分别解压以上程序...
 
- shell $> cd nginx-1.1.5 
- shell $> patch -p0 < ../tbje-nginx-upstream-jvm-route-6016b39/jvm_route.patch  
- shell $> useradd www  
- shell $> ./configure --user=www --group=www --prefix=/usr/nginx/nginxserver --with-http_stub_status_module --with-http_ssl_module=/usr/nginx/openssl-1.0.0e  --add-module=/usr/nginx/tbje-nginx-upstream-jvm-route-6016b39  
- shell $> make  
- shell $> make install  
shell $> cd nginx-1.1.5 shell $> patch -p0 < ../tbje-nginx-upstream-jvm-route-6016b39/jvm_route.patch shell $> useradd www shell $> ./configure --user=www --group=www --prefix=/usr/nginx/nginxserver --with-http_stub_status_module --with-http_ssl_module=/usr/nginx/openssl-1.0.0e  --add-module=/usr/nginx/tbje-nginx-upstream-jvm-route-6016b39 shell $> make shell $> make install 
    到nginxserver/sbin目录下,,运行./nginx 访问http://127.0.0.1  出现“webcome to nginx”代表nginx安装成功
 
  四,配置集群
   打开nginxserver/conf/nginx.conf文件。

- start nginx   开启nginx  
-  
 
-   Nginx -s stop         快速关闭Nginx,可能不保存相关信息,并迅速终止web服务。(quick exit)  
-   Nginx -s quit         平稳关闭Nginx,保存相关信息,有安排的结束web服务。(graceful exit)  
-   Nginx -s reload       因改变了Nginx相关配置,需要重新加载配置而重载。(changing configuration,start a new worker,quitting an old worker gracefully.)  
-   Nginx -s reopen       重新打开日志文件。(reopenging log files)

 上面两resin的服务器已经打开,更改两服务器下的如(resinserver1):/usr/resin/resinserver1/resinserver1/webapps/ROOT 下的index.jsp
   区别服务器访问路径:
- <%@page language="java" import="java.util.*" pageEncoding="UTF-8"%>  
-         <%  
-         %>  
-         <html>  
-           <head>  
-             </head>  
-               <body>  
-                nginxserver1<!--在另一台服务器上写nginxserver2-->  
-                 <br />  
-                <%out.print(request.getSession()) ;%>  
-                 <br />  
-                 <%out.println(request.getHeader("Cookie")); %>  
-               </body>  
-          </html>  
<%@page language="java" import="java.util.*" pageEncoding="UTF-8"%>         <%         %>         <html>           <head>             </head>               <body>                nginxserver1<!--在另一台服务器上写nginxserver2-->                 <br />                <%out.print(request.getSession()) ;%>                 <br />                 <%out.println(request.getHeader("Cookie")); %>               </body>          </html>  这时重启nginx
 
 这时访问:http://127.0.0.1/index.jsp会出现以下情况:
- 比较  
- resinserver1----->  
- nginxserver1   
- SessionImpl[aaadbhbcljrab7wtdprmt,]   
- JSESSIONID=aaadbhbcljrab7wtdprmt  
-  
 
- 或者  
- resinserver2----->  
- nginxserver2   
- SessionImpl[aaadbhbcljrab7wtdprmt,]   
- JSESSIONID=aaadbhbcljrab7wtdprmt  
自我总结:
1,下面这个端口号也要变,不然只能启动一个resin实例(未解)
<!-- SSL port configuration: -->
      <http address="*" port="8444">
        <jsse-ssl self-signed-certificate-name="resin@localhost"/>
      </http>
2,上面那两个软件windows中不能安装,会报异常,改成以下配置,
 upstream backend {   
       server 127.0.0.1:8080 ;     
       server 127.0.0.1:8081;    
      
       }   
nginx_upstream_jvm_route 是一个 
Nginx 的扩展模块,用来实现基于 Cookie 的 Session Sticky 的功能。
            session replication 策略是复制会话,即一个用户访问了一次就把session复制到所有的服务器或这一部分服务器。
这样的好处是如果正访问的服务器down了 用户可以自动被转到别的服务器session不丢失。缺点当然是效率低。
             session sticky策略则是不复制,一个用户访问了一次后,同一个session周期内,所有的请求都定向到这个服务器,
down了session就丢了。
3,启动不同服务名称的resin实例时,要到命令行去,不然不知道启动哪个,报异常。
到G:\javaWeb\resin-pro-2\bin\目录: 
start.bat -server resinserver2 start
