Nginx1.1实现Resin4集群

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

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

 　　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

 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

 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

 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

    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。

 user  www www;#工作进程的属主
 worker_processes  2;#工作进程数，一般与 CPU 核数等同

 error_log  logs/error.log crit;
 #error_log  logs/error.log  notice;
 #error_log  logs/error.log  info;

 pid        logs/nginx.pid;


 events {
     worker_connections  1024;#每个工作进程允许最大的同时连接数
 }


 http {
         upstream backend {#集群服务器
        server 127.0.0.1:8080 srun_id=resinserver1;
        server 127.0.0.1:8081 srun_id=resinserver2;
        jvm_route $cookie_JSESSIONID|sessionid;#session共享
        }

     include       mime.types;#内定义各文件类型映像，也可使用
     default_type  application/octet-stream;#设置默认类型是二进制流

     #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
     #                  '$status $body_bytes_sent "$http_referer" '
     #                  '"$http_user_agent" "$http_x_forwarded_for"';

     #access_log  logs/access.log  main;

     sendfile        on;
     #tcp_nopush     on;

     #keepalive_timeout  0;
     keepalive_timeout  65;

     #gzip  on;#打开gzip文件压缩

     server {
         listen       80;
         server_name  localhost;

         charset UTF-8;

 　　　　#下面为location的配置，可以根据自己的业务情况进行定制
         #access_log  logs/host.access.log  main;
         location / {
             root   html;
             index  index.html index.htm;
         }

         #error_page  404              /404.html;

         # redirect server error pages to the static page /50x.html
         #
         error_page   500 502 503 504  /50x.html;
         location = /50x.html {
             root   html;
         }
              location ~ .*\.jsp$
        {
          proxy_pass  http://backend;
          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 $http_host;
        }
        location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
        {
          expires      30d;
        }
        location ~ .*\.(js|css)?$
        {
          expires      1h;
        }

         # proxy the PHP scripts to Apache listening on 127.0.0.1:80
         #
         #location ~ \.php$ {
         #    proxy_pass   http://127.0.0.1;
         #}

         # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
         #
         #location ~ \.php$ {
         #    root           html;
         #    fastcgi_pass   127.0.0.1:9000;
         #    fastcgi_index  index.php;
         #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
         #    include        fastcgi_params;
         #}

         # deny access to .htaccess files, if Apache's document root
         # concurs with nginx's one
         #
         #location ~ /\.ht {
         #    deny  all;
         #}
     }


     # another virtual host using mix of IP-, name-, and port-based configuration
     #
     #server {
     #    listen       8000;
     #    listen       somename:8080;
     #    server_name  somename  alias  another.alias;

     #    location / {
     #        root   html;
     #        index  index.html index.htm;
     #    }
     #}


     # HTTPS server
     #
     #server {
     #    listen       443;
     #    server_name  localhost;

     #    ssl                  on;
     #    ssl_certificate      cert.pem;
     #    ssl_certificate_key  cert.key;

     #    ssl_session_timeout  5m;

     #    ssl_protocols  SSLv2 SSLv3 TLSv1;
     #    ssl_ciphers  HIGH:!aNULL:!MD5;
     #    ssl_prefer_server_ciphers   on;

     #    location / {
     #        root   html;
     #        index  index.html index.htm;
     #    }
     #}

 }

   nginx命令：

 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>

 　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
