Upgrade go

It is used to uninstall the version of go in the same way as the installation

If go was previously installed through Yum or apt get, execute the relevant code to uninstall it:
yum remove go
apt-get remove go
If it is installed manually (that is, by copying to a directory), you can directly delete the go folder according to the path provided by goroot
rm -r /opt/go

Install the new version of go

Unzip:tar zxvf go1.41.linux-amd64.tar.gz

After getting the go folder, move or copy it to the go installation path you just obtained
mv ./go /opt/

The whole process keeps the environment variable unchanged, otherwise it needs to be re specified
export PATH="/usr/local/go/bin:$PATH"
