1. Backup

In Before upgrading and installing Golang, be sure to back up important data files to prevent data loss.

2. Clean up the old version

Before upgrading to the new version, you should clean up the old version of Golang, otherwise version inconsistencies may lead to compilation errors.

3. Network environment

In the process of upgrading the new version of Golang, it is necessary to ensure that the network is stable to avoid network failures during the download process, causing the upgrade to fail.

2. Golang upgrade and installation steps

$ tar -C /usr/local -zxvf go1.16.5.linux-amd64.tar.gz

Among them, "go1.16.5.linux-amd64.tar.gz" is the Golang version to be installed. Just replace it with your own version number as needed.

4. Configure environment variables

Configuring environment variables is actually adding the path of Golang to the system's environment variables. The purpose of this is to facilitate the use of Golang. Enter the following command on the command line:

$ export GOROOT=/usr/local/go
$ export PATH=$PATH:$GOROOT/bin

Note that the path here needs to be modified according to your actual situation.

5. Verify the installation result

After completing the above steps, we need to test whether the installation result is successful. We can enter the following command through the command line:

$ go version

If the correct version number is output, the installation is successful.

3. Summary

Golang upgrade and installation is a very simple matter. You only need to make simple preparations and follow the steps to complete. During this process, attention should be paid to backing up important data, cleaning up old versions, maintaining network stability, selecting the correct Golang version, etc. Only by making preparations in these aspects can the Golang upgrade and installation be successfully completed.
