6. Preparation

Before installing Golang 1.5, some preparations need to be made, including obtaining a Linux machine and an ordinary user.

Create a normal user using the following command:

$ sudo adduser go

Then, set a password for this new user:

$ sudo passwd go

Next, switch to this new user and verify sudo permissions ：

$ su - go
$ sudo ls

2. Download Golang 1.5

Before installing Golang1.5, you need to download the Golang installation package first.

Visit Golang’s official website https://golang.org/dl/ and find the download link for Golang 1.5 on the page. The downloaded file name is go1.5.linux-amd64.tar.gz.

Use the following command to download Golang 1.5 on the Linux server:

$ wget https://golang.org/dl/go1.5.linux-amd64.tar.gz

3. Install Golang 1.5

After downloading the tar package of Golang 1.5, you can Unzip it with the following command:

$ sudo tar -C /usr/local -xzf go1.5.linux-amd64.tar.gz

After decompression, you will see a new folder go in the /usr/local/go directory. This folder contains Golang 1.5 executable files and library files.

Next let us create a workspace for the Go language for writing and running our Go applications.

First, create a bin directory and src directory:

$ mkdir ~/go
$ mkdir ~/go/bin
$ mkdir ~/go/src

Then, create a .goroot folder in the user’s home directory and add the GOPATH environment variable:

$ mkdir ~/.goroot
$ echo 'export GOPATH="$HOME/go"' >> ~/.bashrc
$ echo 'export PATH="$PATH:/usr/local/go/bin:$GOPATH/bin"' >> ~/.bashrc

4. Set environment variables

In order for us to access the Golang 1.5 executable file in the terminal, we need to set some environment variables.

Open the .bashrc file using the following command and add the following content:

$ nano ~/.bashrc

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

Save and exit the file. Next execute the following command to make the changes take effect:

$ source ~/.bashrc

5. Test the installation results

We are ready to install Golang 1.5. Run the following command below to test the installation result:

$ go version

Output the following information, indicating that Golang 1.5 has been installed successfully:

go version go1.5 linux/amd64

Summary

After completing the steps listed in this article, you Golang 1.5 should have been successfully installed on your Linux server and ready for your next project.
