Start

# startup.shUsing CATALINA_BASE:   /usr/java/tomcat7Using CATALINA_HOME:   /usr/java/tomcat7Using CATALINA_TMPDIR: /usr/java/tomcat7/tempUsing JRE_HOME:        /usr/java/jdk7Using CLASSPATH:       /usr/java/tomcat7/bin/bootstrap.jar:/usr/java/tomcat7/bin/tomcat-juli.jarTomcat started.

Close

# Shutdown. sh

Access

Http: // localhost: 8080/

Access outside the VM

Http: // 192.168.10.40: 8080/

192.168.10.40 is the ip address of the Virtual Machine linux system.

If it cannot be opened externally, it indicates a network problem. You can check whether the ip address resolution is correct, whether the firewall is disabled, and whether port 8080 is enabled.

3. Deploy a Java Project

Package the Java project into *. war or copy all content of webContent to a directory, such as test. war, and upload it to linux.

# Mv test. war/usr/java/tomcat7/webapps/

Access path

Http: // 192.168.10.40: 8080/test/

4. Summary

The installation of jdk and tomcat on linux copies the installation file to the linux system. The configuration of tomcat environment variables is not necessary, but for ease of use. The deployment of Java projects is no different on linux and windows.
