如果是先装的Oracle,然后再装tomcat,打开tomcat的默认(测试)网页::8080,测试的结果会出现一个oracle的"飞猪",而不会出现apache的"猫".一般情况下现在的tomcat的端口会给成8081.如果不想改apache.tomcat的端口,可以停掉oracle的http服务,然后把tomcat的默认端口改会成8080,重启后再打开:8080网址测试成功.(但停掉http服务后web程序就连不上oracle数据库,这个时候可以改oracle的配置文件,把端口换成任何一个没有被暂用的端口)一切正常!

To allow the Tomcat server to access the external network, you need to: modify the Tomcat configuration file to allow external connections. Add a firewall rule to allow access to the Tomcat server port. Create a DNS record pointing the domain name to the Tomcat server public IP. Optional: Use a reverse proxy to improve security and performance. Optional: Set up HTTPS for increased security.

To deploy multiple projects through Tomcat, you need to create a webapp directory for each project and then: Automatic deployment: Place the webapp directory in Tomcat's webapps directory. Manual deployment: Manually deploy the project in Tomcat's manager application. Once the project is deployed, it can be accessed by its deployment name, for example: http://localhost:8080/project1.

Running projects with different port numbers on the Tomcat server requires the following steps: Modify the server.xml file and add a Connector element to define the port number. Add a Context element to define the application associated with the port number. Create a WAR file and deploy it to the corresponding directory (webapps or webapps/ROOT). Restart Tomcat to apply changes.
