How to quickly deploy Golang programs (process sharing)

Golang is a fast, efficient, and concurrent programming language that is widely used in fields such as network services, data processing, and cloud computing. In actual projects, how to deploy Golang programs to ensure high availability and stability of the programs is also very important.

This article will introduce the deployment process of Golang programs, including selecting servers, installing Golang environment, compiling deployment programs, configuring automated deployment, etc. By studying this article, you will master the basic skills of Golang program deployment and be able to quickly deploy your own Golang program.

1. Select a server

To deploy a Golang program, you must first choose a suitable server. Depending on the actual needs and scale of the project, you can choose different forms of servers such as cloud servers, physical servers or virtual machines.

Generally speaking, if the project scale is relatively small, you can consider choosing a cloud server for deployment. Cloud servers can be flexibly expanded and reduced according to the actual needs of the project, while also ensuring the reliability and stability of the server.

If the project scale is relatively large, you can choose physical servers or virtual machines for deployment. The performance and resources of physical servers are more stable and sufficient, but the cost is also higher; virtual machines are relatively more flexible and cheaper, but they require a certain understanding of the performance and stability of virtual machines.

2. Install the Golang environment

After selecting the server, you need to install the Golang environment. The installation of Golang is very simple. Just execute the following command on the server:

wget https://golang.google.cn/dl/go1.16.5.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.16.5.linux-amd64.tar.gz

After the installation is completed, you also need to set the Golang environment variable and add the Golang bin directory to the PATH. You can add the following content to .bashrc or .bash_profile:

export GOPATH=$HOME/go
export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin

Execute source .bashrc or source .bash_profile to make the environment variables take effect.

3. Compile and deploy the program

After installing the Golang environment, you can start writing and deploying Golang programs. First you need to write the program code, and then use the go build command to compile it.

After compilation is completed, you can use the nohup command to run the program in the background to prevent the program from stopping after the ssh session is closed.

nohup ./programname &

In order to facilitate management and monitoring of program operation, you can also use process daemon tools such as Supervisor for management.

4. Configure automated deployment

In actual projects, the deployment of Golang programs also needs to follow the principles of automated deployment to ensure the high availability and stability of the program. You can use container technology such as Docker to package programs into images for rapid deployment and expansion.

At the same time, you can also cooperate with continuous integration tools such as Jenkins to achieve automatic deployment upon code submission. This can greatly shorten deployment time and reduce the workload of manual management.

Summary

Deploying a Golang program requires selecting a suitable server, installing the Golang environment, compiling the deployment program, and configuring automated deployment. After mastering these basic skills, you can quickly deploy your own Golang program to achieve high availability and stable operation.
