How to upgrade golang?

Upgrade Golang

1. Uninstall the old version

3. Install the new version

4. Configure environment variables

Detailed steps:

1. Uninstall the old version

First, execute go env, list Out the environment information about go, check the value of GOROOT, which generally represents the installation path of go;
For example:

GOROOT="/usr/local/go"

After that,

if it was installed through yum or apt-get before Go, then execute the relevant code to uninstall it:

yum remove go
apt-get remove go

If it is installed directly manually (that is, installed by copying to a certain directory), you can directly delete the go folder according to the path provided by GOROOT :

rm -r /usr/local/go

2. Download the new version

Go to the official website to download the latest version, such as go1.11.linux-amd64.tar.gz

3. Install the new version

Unzip: tar zxvf go1.11.linux-amd64.tar.gz

After getting the go folder, move or copy it to the go installation path you just obtained:

mv ./go /usr/local/

4. Configure environment variables

Add the path of the go executable file to PATH:

export PATH="/usr/local/go/bin:$PATH"

If the path of the previous version is the same, there is no need to add it repeatedly.
