golang backend deployment

With the development of Internet technology, golang has gradually become one of the popular languages ​​​​for back-end development. It has the characteristics of high efficiency, stability, flexibility, etc., as well as rich open source ecosystem and community support, allowing more and more enterprises and developers to choose to use golang for back-end development.

So how to deploy the golang backend to the online environment? Here are some steps and considerations for your reference.

1. Prepare the relevant environment

1. Install the golang environment

First, you need to install the golang environment on the server. You can go to golang official website to download the latest version and install it. After the installation is complete, run the go version command to confirm that the golang environment has been installed correctly.

2. Deploy database

If the golang backend needs to use a database, the database environment needs to be deployed first. The more common databases include MySQL, PostgreSQL, etc. It is recommended to place the database and application on different servers, which will help improve the stability of the application.

3. Deploying Nginx

Nginx is a high-performance web server that can also be used as a reverse proxy server, load balancing server, etc. When deploying the golang program, you can use Nginx as a reverse proxy server to forward user requests to the golang program for processing.

2. Compile and package golang program

1. Write golang program

First, you need to write golang program. You can use any editor to write golang programs, such as VS Code, Sublime Text, etc. After writing is completed, it needs to be compiled.

2. Compile into a binary file

Use the go build command to compile the golang program into a binary file. In the Linux system, use CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build command to compile into a 64-bit executable file under the Linux system.

3. Package into a tar.gz file

Package the compiled binary files and related static files into a tar.gz file. You can use the following command to achieve this:

tar -czvf app.tar.gz app

Among them, app is the name of the folder that needs to be packaged, which can be modified according to the actual situation.

3. Upload the golang program to the server

Use the ftp or scp command to upload the packaged golang program to the server. After uploading, decompress the tar.gz file:

tar -xzvf app.tar.gz

4. Deploy the golang program

1. Configure Nginx reverse proxy

Open the Nginx configuration file (usually located in /etc/nginx/nginx.conf) and add the following code:

server {

    listen 80;
    server_name localhost;
    location / {
            proxy_pass http://127.0.0.1:8080;
    }

}

Among them, 127.0.0.1:8080 is the listening address and port number of the golang program.

2. Run the golang program

Use the nohup command to run the golang program:

nohup ./app > app.log 2>&1 &

Among them, app is the file name of the golang program, and app.log is the log file name. Run the program in the background and output the log to the app.log file.

3. Verify whether the deployment is successful

Enter the IP address or domain name of the server in the browser. If it can be accessed normally, it means that the golang backend has been successfully deployed online. environment.

Summary

Through the above steps, we can deploy the golang backend program to the online environment. It should be noted that during the deployment process, some best practices should be followed, such as placing the database and application on different servers, using reverse proxy servers such as Nginx, etc. This improves program stability and security. At the same time, if you need to upgrade or expand, you can also make corresponding modifications according to the actual situation.
