How to deploy Golang project on Ubuntu system

As a developer, how to quickly and stably deploy and run code is one of the essential skills when building a project development environment. This article will share how to deploy Golang projects on Ubuntu systems.

Before starting, you need to complete the following steps:

1. Install the Golang environment
2. Install the Git tool

Next, We will explain it in the following steps.

Step 1: Get the code

First, we need to get the project code. Enter the following command in the terminal:

git clone https://github.com/username/repository.git

Where, https://github.com/username/repository.git is the Git address of the project, which can be found on the project homepage.

Step 2: Compile the code

After completing the code pull, we need to use the Golang tool chain to compile. In the project directory, enter the following command:

go build main.go

Among them, main.go is the entry file of the project. After executing this command, an executable file will be generated in the project directory.

Step 3: Run the code

After completing the compilation, we can run the executable file directly. Enter the following command in the terminal:

./main

After executing this command, the executable file will start running.

Step 4: Configure background running

In actual deployment, we need to run the application in the background to ensure stability and durability. The following are two commonly used methods:

Use the nohup command

nohup can make the program run in the background and redirect the output to the specified file, thereby avoiding program corruption caused by the user exiting the terminal. Force quit.

Enter the following command in the terminal:

nohup ./main > log.txt 2>&1 &

Among them:

• nohup Start the program and ignore the HUP signal so that the program can Running in the background;
• ./main is the path and file name of the executable file;
• > log.txt The information output by the program Redirect to the log.txt file;
• 2>&1 Combine standard error output and standard input and output and redirect to log.txt In the file;
• & Put the program to run in the background.

Use systemd service

systemd is a commonly used system management tool that can manage system services, processes, etc. We can encapsulate the Golang project into a systemd service to achieve automatic startup, automatic restart and other functions.

The following is an example of a systemd service file:

[Unit]
Description=My Go Application

[Service]
Type=simple
Restart=always
User=root
ExecStart=/path/to/app/main

[Install]
WantedBy=multi-user.target

In this service file, we need to define the description, type, restart mechanism and other configuration items of the service. For the meaning of specific configuration items, please refer to the systemd official documentation.

After the configuration is completed, we can use the following command to start the service:

systemctl start my-go-app.service

It should be noted that the service file needs to be stored in the /etc/systemd/system directory , and ends with .service.

At this point, we have completed the entire process of deploying the Golang project on the Ubuntu system. By mastering the above skills, you can quickly and stably deploy and run Golang projects, thereby improving development efficiency and code reliability.
