Nginx配置二级域名的流程
上级目录

1.购买域名

示例:example.com

2.设置多个二级域名。如图:

  1. 配置tomcat文件:

修改tomcat/conf目录下的server.xml文件:
  1. 如下配置配置了3个容器,使用三个不同的端口。
  2. 请注意三点:

①端口号:Connector port;
②容器名称:portservice name;
③项目存放地址:Host appBase;

  1. 示例配置如下,可直接使用。
<Service name="Catalina">
    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
    <Engine name="Catalina" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>
      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
      </Host>
    </Engine>
  </Service>
  
  <Service name="Catalina1">
    <Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    <Connector port="8010" protocol="AJP/1.3" redirectPort="8443" />
    <Engine name="Catalina1" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>
      <Host name="localhost"  appBase="webapps1"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
      </Host>
    </Engine>
  </Service>
  
  <Service name="Catalina2">
    <Connector port="8082" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    <Connector port="8011" protocol="AJP/1.3" redirectPort="8443" />
    <Engine name="Catalina1" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>
      <Host name="localhost"  appBase="webapps2"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
      </Host>
    </Engine>
  </Service>
  1. 在tomcat根目录下,复制webapps文件夹,并在tomcat根目录下粘贴两份,分别命名为:webapps1和webapps2。注意此文件夹名称需要与第一步server.xml中添加的Host appBase名称一致。示例图如下:

  2. 在tomcat/conf文件夹下

    复制Catalina,并在tomcat/conf目录下粘贴两份(Catalina文件夹下的localhost文件夹不要更改名称,否则server.xml所添加的配置也需要改动。为不引起麻烦事,建议直接复制Catalina文件夹即可),分别命名为:Catalina1和Catalina2,注意此文件夹命名需要与第一步server.xml中添加的portservice name名称一致。示例图如下:

  1. 配置Nginx反向代理:修改nginx/conf目录下的nginx.conf文件,添加反向代理配置与虚拟主机配置:

#反向代理
    upstream www.example.com{
        server 110.110.110.110:8080;    #主机ip+端口号
    }        
    upstream me.example.com{
        server 110.110.110.110:8081;
    }
    upstream dev.example.com{
        server 110.110.110.110:8082;
    }
          
#配置虚拟主机  
    server {  
        listen 80;  
        server_name www.example.com;  
        index index.jsp index.html index.htm; 
        
        #include proxy-pass-php.conf;
        
        location / {  
                proxy_pass http://www.example.com;    #与server_name保持一致
                proxy_set_header Host $http_host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
        access_log  /home/wwwlogs/www.example.com.log;
    } 
    
    server {  
        listen 80;  
        server_name me.example.com;  
        index index.jsp index.html index.htm; 
        
        #include proxy-pass-php.conf;
        
        location / {  
                proxy_pass http://me.example.com;
                proxy_set_header Host $http_host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
        access_log  /home/wwwlogs/me.example.com.log;
    } 
    
    server {  
        listen 80;  
        server_name dev.example.com;  
        index index.jsp index.html index.htm; 
        
        #include proxy-pass-php.conf;
        
        location / {  
                proxy_pass http://dev.example.com;  
                proxy_set_header Host $http_host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;                
        }  
        access_log  /home/wwwlogs/dev.example.com.log;
    }  
          
include vhost/*.conf;
  1. 完成配置后,在tomcat中分别于webapps、webapps1、webapps2文件夹下部署三个不同的项目,项目名称都命名为ROOT.war。启动tomcat,分别访问www.example.com(http://www.example.com)、me.example.com、dev.example.com即可。
