Example

3.1 Loading Tomcat

If for some reason you decide to install Tomcat manually, then you will need more instructions. To get started, again, download Tomcat from the page . But this time we select the zip archive at the very top:

3.2 Installing Tomcat

Installing Tomcat is very simple. After you download the zip file in the previous step, extract its contents to a specific folder. For example, inD:\DevPrograms:

To run Tomcat, you must have JRE 8 or higher installed on your computer. If you have several JREs installed, it is recommended to register one specific one directly in the Tomcat settings.

3.3 Configuring Tomcat

To do this, open the tomcat-users.xml file (Located in the Tomcat 9.0\ conf folder ):

There will already be content like:

Change usernameto passwordthe ones you like. Well, or at least remember the place where you can peep them when you need them. If you change these settings while Tomcat is running, you will need to restart it for them to take effect.

<role rolename="tomcat"/>
  <role rolename="manager-gui"/>
  <role rolename="manager-script"/>
  <user username="tomcat" password="111" roles="tomcat, manager-gui, manager-script"/>

3.4 Starting and stopping Tomcat

To start Tomcat, double click on startup.bat (Or startup.sh for Linux/Ubuntu). To stop use the file shutdown.bat

You will see something like this - this is a running Tomcat:

If Tomcat is installed correctly, then at the link http://localhost:8080/ you will see a picture:
