Install and configure Tomcat using Linux

To start installing Tomcat on Linux, specific code examples are required

Tomcat is a very popular open source Java Servlet container that can be used to run Java Web applications. Installing and configuring Tomcat on a Linux operating system is relatively simple, just follow the steps below. This article will introduce how to install and configure Tomcat on a Linux system and provide specific code examples.

Step 1: Download Tomcat

First, we need to download the latest version of the Tomcat installation package from the Apache Tomcat official website (https://tomcat.apache.org/). When choosing a download version, please pay attention to the version that is compatible with your operating system. Once the download is complete, save the installation package in the directory of your choice.

Step 2: Decompress Tomcat

Next, we need to decompress the Tomcat installation package we just downloaded. In the terminal, switch to the directory where you saved the installation package and run the following command to decompress the installation package:

tar -zxvf apache-tomcat-9.0.45.tar.gz

The above command will decompress the .tar.gz file. Depending on the specific file type you are downloading, you may need to adjust the command. After unzipping, a directory named apache-tomcat-9.0.45 (varies depending on the downloaded version) will be created in the current directory, which contains all files of Tomcat.

Step 3: Configure environment variables

Before using Tomcat, we need to configure some environment variables. Open a terminal and open the ~/.bashrc file using your favorite text editor:

nano ~/.bashrc

Add the following line at the end of the file:

export CATALINA_HOME=/path/to/tomcat
export PATH=$PATH:$CATALINA_HOME/bin

Please replace "/path/to/tomcat "The path to unzip Tomcat for you. Save and close the file.

Run the following command to load the new bash configuration:

source ~/.bashrc

Step 4: Start Tomcat

Now, we are ready to start Tomcat. In the terminal, switch to Tomcat's bin directory and run the following command:

./catalina.sh start

The above command will start Tomcat and run it as a background process. If all goes well, you should be able to visit http://localhost:8080 in your browser and see Tomcat's welcome page.

Step 5: Configure Tomcat

For more advanced configuration, you can edit Tomcat's configuration file. Open a terminal and use your text editor to open the $CATALINA_HOME/conf/server.xml file:

nano $CATALINA_HOME/conf/server.xml

In the file, you can configure Tomcat's settings for ports, connectors, virtual hosts, etc. Make the appropriate modifications based on your needs and save the file.

Step 6: Shut down Tomcat

When you finish using Tomcat, you can shut down Tomcat. In the terminal, switch to Tomcat's bin directory and run the following command:

./catalina.sh stop

The above command will stop Tomcat from running.
