在Tomcat部署多項目，通過Nginx反向代理分別配置二級功能變數名稱的流程

購買功能變數名稱。示例：example.com

設置多個二級功能變數名稱。如圖：

配置tomcat文件：

1. 修改tomcat/conf目錄下的server.xml文件：

   1. 如下配置配置了3個容器，使用三個不同的埠。
   2. 請註意三點：①埠號：Connector port；②容器名稱：portservice name；③項目存放地址：Host appBase；
   3. 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>

2. 在tomcat根目錄下，複製webapps文件夾，併在tomcat根目錄下粘貼兩份，分別命名為：webapps1和webapps2。註意此文件夾名稱需要與第一步server.xml中添加的Host appBase名稱一致。示例圖如下：

3. 在tomcat/conf文件夾下，複製Catalina，併在tomcat/conf目錄下粘貼兩份（Catalina文件夾下的localhost文件夾不要更改名稱，否則server.xml所添加的配置也需要改動。為不引起麻煩事，建議直接複製Catalina文件夾即可），分別命名為：Catalina1和Catalina2，註意此文件夾命名需要與第一步server.xml中添加的portservice name名稱一致。示例圖如下：

配置Nginx反向代理：修改nginx/conf目錄下的nginx.conf文件，添加反向代理配置與虛擬主機配置：

#反向代理
    upstream www.example.com{
        server 110.110.110.110:8080;    #主機ip+埠號
    }        
    upstream me.example.com{
        server 110.110.110.110:8081;
    }
    upstream dev.example.com{
        server 110.110.110.110:8082;
    }
          
#配置虛擬主機  
    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;    #與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;

完成配置後，在tomcat中分別於webapps、webapps1、webapps2文件夾下部署三個不同的項目，項目名稱都命名為ROOT.war。啟動tomcat，分別訪問www.example.com、me.example.com、dev.example.com即可。
