  <!-- 第二个项目配置 -->
  <Service name="Catalina1">
      
    <!-- 为避免冲突, 修改端口 -->
    <Connector port="81" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
  
    <!-- Tomcat默认使用8009端口, 避免冲突, 修改 -->
    <Connector port="8010" protocol="AJP/1.3" redirectPort="8443"/>
  	
    <!-- Engine 节点, name 修改为 Catalina1 -->
    <!-- 服务启动后会在 conf 下生成相应的引擎文件夹, 名称保持一致. -->
    <Engine name="Catalina1" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>
  
      <!-- 修改Host节点，appBase修改为需要进行发布的文件位置, 也就是第一步复制的 webapps1 -->
      <Host name="localhost"  appBase="webapps1"
            unpackWARs="true" autoDeploy="true">
  
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"

upstream website{
                server localhost:81;
                server localhost:82;
        }

                }
        }
复制代码

3- Complete the deployment

 After the above two steps are completed tomcat, Nginxrestart, and the two applications can be accessed through the domain name alone.

# 进入到 bin 目录下重启 tomcat
./shutdown.sh
./startup.sh
复制代码

# 进入到 sbin 目录下重启 nginx
./nginx -s reload
