Check your <tomcat_home>/conf/server.xml file to determine how a WAR will be deployed. In this example server.xml file, WAR files placed in the <tomcat home>/webapps directory will automatically be deployed and unpacked.
<Host appBase="webapps" autoDeploy="true" deployOnStartup="true" deployXML="true" name="localhost" unpackWARs="true">
After placing a WAR in the webapps directory, wait a few moments, and the WAR should automatically be unpacked and deployed. In this example, myApp.war has been unpacked into the myApp directory. When the WAR file is placed in the webapps directory, the date and time of the WAR file should reflect the current date and time. When the WAR is unpacked, the WAR file directory should be updated to have the current date and time.
~]# ll /opt/tomcat/webapps/ drwxr-x---. 4 root root 51 Jul 4 10:14 myApp -rwxr--r--. 4 root root 2122 Jul 4 10:14 myApp.war drwx------. 4 root root 51 Jul 4 10:14 ROOT
There will also be an event in catalina.log for the deploy.
Apr 04, 2018 8:00:42 PM org.apache.catalina.startup.HostConfig deployWAR INFO: Deploying web application archive /opt/tomcat/profiles/myJVM/webapps/myApp.war Apr 04, 2018 8:00:59 PM org.apache.catalina.startup.HostConfig deployWAR INFO: Deployment of web application archive /opt/tomcat/profiles/myJVM/webapps/myApp.war has finished in 15,040 ms
Accessing your application
In the prior examples, an application named MyWebApp was deployed. This application can be accessed by navigating to http://www.example.com:8080/MyWebApp.
If the name of the WAR contains the # character, such as apps#sample.war, the URL will then be http://www.example.com:8080/apps/sample.
