How to install golang to Ubuntu 20.04

Download

wget -c https://golang.org/dl/go1.16.4.linux-amd64.tar.gz -O - | sudo tar -xz -C /usr/local
           

Or

sudo tar -C /usr/local/ -xzf go1.16.4.linux-amd64.tar.gz
           

Configuration

Add the go_path variable to the configuration file

sudo tee /etc/profile.d/go.sh <<-'EOF'
export GOROOT=/usr/local/go
export GOPATH=~/go
export PATH=$PATH:$GOROOT/bin:$GOPATH
export GO111MODULE=on
export GOPROXY=https://goproxy.cn,direct
EOF
           

According to the official golang documentation, after go language 1.8, the setting of the GOPATH variable is optional, so it is not necessary to set it here. In this way, the content of the above-mentioned environment variable configuration file can be configured as follows.

sudo tee /etc/profile.d/go.sh <<-'EOF'
export GOROOT=/usr/local/go
#export GOPATH=~/go
#export PATH=$PATH:$GOROOT/bin:$GOPATH
export PATH=$PATH:$GOROOT/bin
export GO111MODULE=on
export GOPROXY=https://goproxy.cn,direct
EOF
           

Enable the ability to automatically append GOPATH at boot

tee -a ~/.bashrc <<-'EOF'
if [ -f /etc/profile.d/go.sh ]; then
    . /etc/profile.d/go.sh
fi
EOF
           

Make environment variables take effect

source .bashrc
