5.3. 网站配置和示例

网站配置层次关系：

listen(侦听) - website(网站) - forward_server(反向代理转发服务器)

一个hetao运行实例里可以有多个listen，每个listen为一个ip、port对，对应一个TCP服务端侦听。每个listen上可以配置多个网站website，基于域名domain识别虚拟主机。每个website上可以配置成某一文件类型forward_type转发到后方应用服务器forward_server，以及负载均衡算法forward_rule。

domain需要匹配浏览器访问Web服务器请求头选项Host的值（URL中"http://"与"/"之间的部分）以确定服务器使用哪个虚拟主机来响应，如：

http://www.google.com/        domain为"www.google.com"
http://192.168.1.110:8080/    domain为"192.168.1.110:8080"

5.3.1. 简单的网站配置

    "listen" :
    {
        "ip" : "" ,
        "port" : 80 ,
        "website" :
        {
            "domain" : "" ,
            "wwwroot" : "/var/hetao/www" ,
            "index" : "/index.html,/index.htm" ,
            "access_log" : "/var/hetao/log/access.log"
        }
    } ,

5.3.2. 带域名的虚拟主机网站配置（两个虚拟主机）

    "listen" :
    {
        "ip" : "" ,
        "port" : 80 ,
        "website" :
        {
            "domain" : "www.test.com" ,
            "wwwroot" : "/var/hetao/www.test.com" ,
            "index" : "/index.html,/index.htm" ,
            "access_log" : "/var/hetao/log/www_test_com_access.log"
        } ,
        {
            "domain" : "www.test2.com" ,
            "wwwroot" : "/var/hetao/www.test2.com" ,
            "index" : "/index.html,/index.htm" ,
            "access_log" : "/var/hetao/log/www_test_com_access.log"
        }
    } ,

5.3.3. 需要改写URI的网站配置（/xxx/yyy改写为/yyy/xxx）

    "listen" :
    {
        "ip" : "" ,
        "port" : 80 ,
        "website" :
        {
            "domain" : "" ,
            "wwwroot" : "/var/hetao/www" ,
            "index" : "/index.html,/index.htm" ,
            "access_log" : "/var/hetao/log/access.log" ,
            "rewrite" : { "pattern":"/(.+)/(.+)" , "new_uri":"/(2)/(1)" }
        }
    } ,

5.3.4. 需要重定向域名的网站配置（www.google.com改写为www.baidu.com）

    "listen" :
    {
        "ip" : "" ,
        "port" : 80 ,
        "website" :
        {
            "domain" : "" ,
            "wwwroot" : "/var/hetao/www" ,
            "index" : "/index.html,/index.htm" ,
            "access_log" : "/var/hetao/log/access.log" ,
            "redirect" : { "domain":"www.google.com" , "new_domain":"http://www.baidu.com" }
        }
    } ,

5.3.5. 简单的HTTPS网站配置

    "listen" :
    {
        "ip" : "" ,
        "port" : 443 ,
        "website" :
        {
            "domain" : "" ,
            "wwwroot" : "/var/hetao/www" ,
            "index" : "/index.html,/index.htm" ,
            "access_log" : "/var/hetao/log/access.log" ,
      "ssl" :
      {
        "certificate_file" : "/etc/hetao/certs/server.pem" ,
        "certificate_key_file" : "/etc/hetao/certs/server.key"
      }
        }
    } ,

5.3.6. 反向代理配置，针对文件类型php，轮询算法

    "listen" :
    {
        "ip" : "" ,
        "port" : 80 ,
        "website" :
        {
            "domain" : "" ,
            "wwwroot" : "/var/hetao/www" ,
            "index" : "/index.html,/index.htm" ,
            "access_log" : "/var/hetao/log/access.log" ,
            "forward" :
            {
                "forward_type" : "php" ,
                "forward_rule" : "R" ,
                "forward_server" : { "ip" : "192.168.6.111" , "port" : 8081 } ,
                "forward_server" : { "ip" : "192.168.6.111" , "port" : 8082 } ,
                "forward_server" : { "ip" : "192.168.6.111" , "port" : 8083 }
            }
        }
    } ,

5.3.7. 反向代理配置，针对文件类型php，轮询算法，转发时装载证书变成HTTPS

    "listen" :
    {
        "ip" : "" ,
        "port" : 80 ,
        "website" :
        {
            "domain" : "" ,
            "wwwroot" : "/var/hetao/www" ,
            "index" : "/index.html,/index.htm" ,
            "access_log" : "/var/hetao/log/access.log" ,
            "forward" :
            {
                "forward_type" : "php" ,
                "forward_rule" : "R" ,
                "ssl" :
                {
                    "certificate_file" : "/etc/hetao/certs/server.crt"
                } ,
                "forward_server" : { "ip" : "192.168.6.111" , "port" : 1443 } ,
                "forward_server" : { "ip" : "192.168.6.111" , "port" : 1443 } ,
                "forward_server" : { "ip" : "192.168.6.111" , "port" : 1443 }
            }
        }
    } ,

5.3.8. SOCGI

URI扩展名为“.do”的HTTP请求，调用应用动态库

    "listen" :
    {
        "ip" : "" ,
        "port" : 80 ,
        "website" :
        {
            "domain" : "localhost" ,
            "wwwroot" : "www" ,
            "index" : "/index.html,/index.htm" ,
            "access_log" : "log/access.log" ,
            "socgi" :
            {
                "socgi_type" : "do" , "socgi_pathfilename" : "www/test_socgi_hello.socgi"
            }
        }
    }

RESTful风格应用的URI一般没有扩展名

    "listen" :
    {
        "ip" : "" ,
        "port" : 80 ,
        "website" :
        {
            "domain" : "localhost" ,
            "wwwroot" : "www" ,
            "index" : "/index.html,/index.htm" ,
            "access_log" : "log/access.log" ,
            "socgi" :
            {
                "socgi_type" : "" , "socgi_pathfilename" : "www/test_socgi_rest_full.socgi"
            }
        }
    }
