How to calculate tomcat startup success

Method to determine if Tomcat starts successfully: Check the log file catalina.out for the "Server startup in" line. Access the management interface (http://localhost:8080/manager/html) and log in successfully. Check port 8080 listening (use netstat -an | findstr command). Try to deploy and access the application. Execute the systemctl status tomcat command on a Unix system. If "active (running)" is displayed, it means it is running.

How to judge whether Tomcat starts successfully

To judge whether the Tomcat server starts successfully, you can follow the following steps:

1. View the log file

• Locate the logs folder in the Tomcat installation directory.
• Open the catalina.out log file.
• Look for a line similar to:

<code>INFO: Server startup in [XXX] milliseconds</code>

If you see this line, Tomcat started successfully.

2. Access the management interface

• Enter http://localhost:8080/manager/html in the browser address bar .
• Enter the username and password (by default, tomcat-user and tomcat).
• If you log in successfully, it means that Tomcat is running.

3. Check the port listening

• Open a command line prompt.
• Run the following command:

<code>netstat -an | findstr 8080</code>

• If you see output similar to the following, Tomcat is listening on port 8080:

<code>TCP [::]:8080 [::]:0 LISTENING</code>

4. Try to deploy the application

• Deploy a simple application (such as Hello World) to Tomcat.
• Visit the URL of the application in your browser.
• If the application can load normally, Tomcat is running.

5. Check the system status

• On some Unix systems, you can use the systemctl status tomcat command to check Tomcat status.
• If active (running) appears in the output, Tomcat is running.
