How to install tomcat in golang

As a high-performance programming language, Golang is widely loved by developers. As an open source Java Servlet container, Tomcat is also one of the tools commonly used by developers. So, how to install Tomcat in Golang? This article will introduce it to you in detail.

Step one: Install the Java environment

Before installing Tomcat, we need to install the Java environment first. First, you can download the Java SE Development Kit (JDK) version from Oracle's official website. After the download is complete, just follow the prompts to install it. After the installation is complete, we need to configure the environment variables and set the JAVA_HOME and PATH parameters. Next, we can enter java -version in the command line window to confirm whether the Java environment has been successfully installed.

Step 2: Download Tomcat

After the Java environment is installed, we can start downloading Tomcat. On Tomcat's official website, we can find and download the latest version of Tomcat, such as Tomcat 9. After the download is complete, unzip it to any folder, such as D:\dev\tomcat-9.0.35.

Step 3: Configure Tomcat

After successfully decompressing Tomcat, we need to configure Tomcat in order to run it successfully. First, we can find the following code segment in D:\dev\tomcat-9.0.35\conf\server.xml:

<Server port="8005" shutdown="SHUTDOWN">

We need to change 8005 to another unoccupied port number, For example 8080. At the same time, we also need to add the following code segment to D:\dev\tomcat-9.0.35\conf\tomcat-users.xml:

<role rolename="manager-gui"/>
<user username="tomcat" password="tomcat" roles="manager-gui"/>

This code will add a login account for the management interface for us tomcat, the password is also tomcat. Finally, we need to add the following system variables to the Windows environment variables:

Variable name: CATALINA_HOME

Variable value: D:\dev\tomcat-9.0.35

After this configuration is completed, we can start Tomcat for testing.

Step 4: Start Tomcat

After completing the above configuration, we can enter the following command in the command line window to start Tomcat:

D:\dev\tomcat-9.0.35\bin\startup.bat

Then we open the browser and Enter http://localhost:8080, and you can see Tomcat's default welcome page. This proves that we have successfully installed and configured Tomcat.

Summary

Golang is a very flexible and efficient programming language, while Tomcat is a very practical Java container. When using Golang with Tomcat, you need to complete the installation of the Java environment first, then download Tomcat and perform relevant configurations, and then start Tomcat for testing.
