Sample code for implementing multi-application deployment using tomcat+nginx

cp webapps webapps1 

cd confvim server.xml

<!-- Second project configuration-->
<Service name="Catalina1">
    
  <!-- To avoid conflicts, change the port -->
  <Connector port="81" protocol="HTTP/1.1"
             connectionTimeout="20000"
             redirectPort="8443" />

  <!-- Tomcat uses port 8009 by default, to avoid conflicts, modify -->
  <Connector port="8010" protocol="AJP/1.3" redirectPort="8443"/>
	
  <!-- Engine node, name changed to Catalina1 -->
  <!-- After the service is started, the corresponding engine folder will be generated under conf, and the name will remain the same. -->
  <Engine name="Catalina1" defaultHost="localhost">
    <Realm className="org.apache.catalina.realm.LockOutRealm">
      <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
             resourceName="UserDatabase"/>
    </Realm>

    <!-- Modify the Host node and change appBase to the location of the file to be published, which is webapps1 copied in the first step -->
    <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>
