Installing Tomcat on Windows can be done easily using the Windows installer. Its interface and functionality is similar to other wizard based installers, with only a few items of interest.
- Installation as a service: Tomcat will be installed as a Windows service no matter what setting is selected. Using the checkbox on the component page sets the service as “auto” startup, so that Tomcat is automatically started when Windows starts. For optimal security, the service should be run as a separate user, with reduced permissions.
- Java location: The installer will provide a default JRE to use to run the service. The installer uses the registry to determine the base path of a Java 7 or later JRE, including the JRE installed as part of the full JDK. When running on a 64-bit operating system, the installer will first look for a 64-bit JRE and only look for a 32-bit JRE if a 64-bit JRE is not found. It is not mandatory to use the default JRE detected by the installer. Any installed Java 7 or later JRE (32-bit or 64-bit) may be used.
- Tray icon: When Tomcat is run as a service, there will not be any tray icon present when Tomcat is running. Note that when choosing to run Tomcat at the end of installation, the tray icon will be used even if Tomcat was installed as a service.
The installer will create shortcuts allowing starting and configuring Tomcat. It is important to note that the Tomcat administration web application can only be used when Tomcat is running.
