First get into your EC2 server | |
If you have already run | |
$ sudo apt-get install golang | |
and you have | |
$ go version | |
go version go1.2.1 linux/amd64 | |
or something else out of date, you need to remove it before anything | |
$ rm -r go | |
$ sudo apt-get remove golang | |
OK now you can get the latest version you want from here: https://golang.org/dl/ | |
and run | |
$ wget https://storage.googleapis.com/golang/go1.4.2.linux-amd64.tar.gz | |
now $ ls and you should see the tarball there: | |
ubuntu@ip-0-0-0-0:~$ ls | |
go1.4.2.linux-amd64.tar.gz | |
Lets untarball it into this directory /usr/local (you need to sudo it) like so: | |
$ sudo tar -C /usr/local -xzf go1.4.2.linux-amd64.tar.gz | |
Now cd into /usr/local | |
$ cd /usr/local | |
now your command should show you are in there like below...and then ls to see what you have in there: | |
ubuntu@ip-0-0-0-0:/usr/local$ ls | |
bin etc games go include lib man sbin share src | |
Above are the untarred files. (yay) | |
Now we have to vim into our file to add this: export PATH=$PATH:/usr/local/go/bin to the end of the: /etc/profile file. | |
$ sudo vim /etc/profile | |
Now you need to get into 'insert' mode by inputting the letter i | |
You will see on the bottom it now says INSERT. Congratulations, you are in insert mode. | |
Now arrow down to the bottom of the page and add | |
export PATH=$PATH:/usr/local/go/bin | |
Great, now save what you did by FIRST hitting esc THEN inputting :w | |
Now get out by inputting :q | |
You should be back on your command line. Now again paste the same line: export PATH=$PATH:/usr/local/go/bin | |
Like so in your command line while still inside /usr/local | |
ubuntu@ip-0-0-0-0:/usr/local$ export PATH=$PATH:/usr/local/go/bin | |
Great Now lets see that we have the correct version: | |
$ go version | |
go version go1.4.2 linux/amd64 | |
Allll riggghhttt! | |
Lets make a simple program to make sure go will run it correctly: | |
vim hello.go will create a file and put you in it to edit it. | |
$ vim hello.go | |
Again use the vim commands | |
i to insert | |
now paste in: | |
package main | |
import "fmt" | |
func main() { | |
fmt.Printf("hello, world\n") | |
} | |
esc to get out | |
:w to save | |
:q to get back to command line | |
If you want to get out without saving use this :q! | |
Now you are back in your command line. Lets see if the program runs right. | |
$ go run hello.go | |
If you see | |
hello, world | |
WOOOOOOT. You did it! | |
