How to integrate Golang log management tools in Debian system

Integrate Go language log management tools on Debian systems, the steps are as follows:

1. Install Go language environment

First, make sure your Debian system has Go installed. If not installed, execute the following command:

 sudo apt update
sudo apt install golang-go

Verify installation:

 go version

2. Select logging tool

Go language has a variety of logging tools, such as logrus, zap, zerolog, etc. This article takes logrus as an example.

3. Install logrus

Use the go get command to install:

 go get github.com/sirupsen/logrus

4. Configure logrus

In your Go project, configure logs. The following example shows how to configure logrus in the main.go file:

 package main

import (
    "github.com/sirupsen/logrus"
    "os"
)

func main() {
    logrus.SetLevel(logrus.DebugLevel) // Set logrus.SetFormatter(&logrus.JSONFormatter{}) // Set log format to JSON
    logrus.SetOutput(os.Stdout) // Set log output to standard output logrus.Debug("Debug Information")
    logrus.Info("Information")
    logrus.Warn("Warning")
    logrus.Error("Error")
}

5. Run the project

Compile and run your Go program:

 go run main.go

The output is similar:

 {"level":"debug","msg":"debug information"}
{"level":"info","msg":"Information"}
{"level":"warn","msg":"warning"}
{"level":"error","msg":"Error"}

6. Integrate into system services (optional)

Registering a Go application as a system service, you can use systemd.

1. Create a systemd service file (for example: myapp.service ) :

 [Unit]
Description=My Go Application
After=network.target

[Service]
ExecStart=/path/to/your/myapp
Restart=always
User=youruser
Group=yourgroup
Environment=GO_ENV=production

[Install]
WantedBy=multi-user.target

Replace /path/to/your/myapp with your executable path, and youruser and yourgroup with the users and groups running the application.

2. Copy the service file :

 sudo cp myapp.service /etc/systemd/system/

3. Reload the systemd configuration :

 sudo systemctl daemon-reload

4. Enable and start the service :

 sudo systemctl enable myapp.service
sudo systemctl start myapp.service

5. Check service status :

 sudo systemctl status myapp.service

Through the above steps, you can successfully integrate the Go language log management tool in the Debian system and run it as a system service. Remember to replace the placeholder in the example with your actual path and username.
