The steps to configure Tomcat 8.5.30 using the server.xml file or the Tomcat Manager web application
After installing Tomcat 8.5.30, you may want to configure some settings and options according to your needs and preferences.
You can configure Tomcat 8.5.30 using two main methods:
The server.xml file, which is an XML file that contains all the configuration parameters for your Tomcat server, such as connectors, hosts, contexts, valves, realms, etc. You can edit this file using a text editor or an XML editor of your choice.
The Tomcat Manager web application, which is a web-based tool that allows you to manage your Tomcat server and its applications remotely from a browser. You can access this tool by entering this URL in your browser: where localhost is your server name or IP address and 8080 is your port number.
Some of the common configuration tasks that you may want to perform are:
Changing the port number for your Tomcat server, which is 8080 by default. You can change this by editing the <Connector> element in the server.xml file and changing the value of the port attribute. For example, to change the port number to 8081, you can use this code: <Connector port="8081" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
Enabling SSL/TLS for your Tomcat server, which allows secure communication over HTTPS protocol. You can enable this by editing the <Connector> element in the server.xml file and adding the attributes for SSL/TLS configuration. For example, to enable SSL/TLS using OpenSSL, you can use this code: <Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="150" SSLEnabled="true" scheme="https" secure="true" SSLProtocol="TLS" SSLCertificateFile="conf/ssl/server.crt" SSLCertificateKeyFile="conf/ssl/server.key" />
Adding or removing web applications to or from your Tomcat server, which allows you to deploy and run your Java web applications on Tomcat. You can add or remove web applications by using the Tomcat Manager web application or by copying or deleting the web application files in the webapps folder inside your Tomcat installation folder.
Setting up user roles and permissions for your Tomcat server, which allows you to control who can access and manage your Tomcat server and its applications. You can set up user roles and permissions by editing the tomcat-users.xml file in the conf folder inside your Tomcat installation folder. For example, to create a user with the role of manager-gui, which allows access to the Tomcat Manager web application, you can use this code: <user username="admin" password="admin123" roles="manager-gui"/>
Monitoring and troubleshooting your Tomcat server, which allows you to check the status and performance of your Tomcat server and its applications and identify and resolve any issues or errors. You can monitor and troubleshoot your Tomcat server by using the Tomcat Manager web application or by checking the log files in the logs folder inside your Tomcat installation folder.
The basic commands and operations for starting, stopping, and managing Tomcat 8.5.30
Once you have installed and configured Tomcat 8.5.30, you can start, stop, and manage it using some basic commands and operations.
If you installed Tomcat as a Windows service, you can use the Services window or the command prompt to start and stop Tomcat. For example, to start Tomcat from the command prompt, you can run this command: net start "Apache Tomcat 8.5". To stop Tomcat from the command prompt, you can run this command: net stop "Apache Tomcat 8.5".
If you did not install Tomcat as a Windows service, you can use the batch files in the bin folder inside your Tomcat installation folder to start and stop Tomcat. For example, to start Tomcat from the command prompt, you can run this command: C:\Tomcat8.5\bin\startup.bat. To stop Tomcat from the command prompt, you can run this command: C:\Tomcat8.5\bin\shutdown.bat.
To manage Tomcat, you can use the Tomcat Manager web application or the command prompt to perform various tasks and operations, such as deploying and undeploying web applications, reloading and restarting web applications, listing and accessing web applications, viewing server status and information, etc.
The methods and tools for deploying and running web applications on Tomcat 8.5.30
One of the main purposes of using Tomcat is to deploy and run your Java web applications on it.
You can deploy and run web applications on Tomcat using different methods and tools, such as:
The Tomcat Manager web application, which allows you to upload and deploy web application files (such as WAR files) from your browser.
The file system, which allows you to copy and paste web application files (such as WAR files or exploded directories) to the webapps folder inside your Tomcat installation folder.
The Ant tool, which allows you to build and deploy web application files (such as WAR files) from your command prompt using an XML script.
The Maven tool, which allows you to build and deploy web application files (such as WAR files) from your command prompt using a POM file.
The Eclipse IDE, which allows you to create, edit, debug, and deploy web application files (such as WAR files) from your integrated development environment.
The best practices and tips for optimizing the performance and security of Tomcat 8.5.30
