Window Nginx+JBoss 负载部署Web

      前段时间了解了下Nginx,找来window版安装了,也成功了。今天看到篇博文,突然想起拿来和JBoss整合部署WEB,如果可以就试用到项目上去。初次接触,难免有错。

       一、到Nginx官网下载最新稳定版本,安装部署(略过。。)。

       二、修改Nginx配置文件nginx-1.8.0\conf下的nginx.conf文件。参考如下(只是在原来的基础上稍微修改,如果需要了解更多可以搜索一下):

       
#user  nobody;
worker_processes  1;

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

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #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;
    #配置JBoss服务
    upstream localhost {
         server 127.0.0.1:8787;
	 server 127.0.0.1:8070;
    }
    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
        #修改掉原来的location,改为如下
	location / {    
		proxy_connect_timeout   3;  
		proxy_send_timeout      30;  
		proxy_read_timeout      30;  
		proxy_pass http://localhost;   
	} 
        #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;
        #}

        # 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 ssl;
    #    server_name  localhost;

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

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

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

}
 

    配置文件只新增一处和修改一处。   

   1、新增upstream localhost,可配置多个JBoss,因为之前改过一个JBoss端口,顺便拿来测试了。

    
#配置JBoss服务
    upstream localhost {
         server 127.0.0.1:8787;
	 server 127.0.0.1:8070;
    }
 

  

   2、把原来的location修改如下:

#修改掉原来的location,改为如下
	location / {    
		proxy_connect_timeout   3;  
		proxy_send_timeout      30;  
		proxy_read_timeout      30;  
		proxy_pass http://localhost;   
	} 
 

  三、按照正常部署一个Web到JBoss中,我简单写了一个例子Web项目,项目名称叫Nginx1。

    修改index.jsp的内容为This is my JSP1 page. 然后打成war包部署到端口为8787的JBoss中;

    同样修改index.jsp的内容为This is my JSP2 page. 然后打成war包部署到端口为8070的JBoss     中;
 四、启动两个JBoss,验证一下发布的web项目有没有问题;

    1、访问http://localhost:8787/Nginx1/index.jsp,结果如下图,没问题

    2、访问http://localhost:8070/Nginx1/index.jsp,结果如下图,没问题

    两个访问都正常,那我们现在开始验证使用Nginx代理访问会怎么样。

五、用doc切换到Nginx安装目录下,输入start nginx.exe启动nginx,访问     http://localhost/Nginx1/index.jsp,第一次访问:(nginx默认监听端口是80)


 再刷新一次:

 

 至此,大功告成,刷新一次相当访问不同的JBoss服务,通过这种方式可以减轻服务的压力,达到负载均衡的目的。此例子很简单,可以作为一个入门了解的例子。
