如何从CentOS删除golang软件包

Question

How to remove golang packages from CentOS. I am unable to "yum remove golang" as it returns a no match error. How do I perform wildcard removal on CentOS to remove all the below packages

golang.x86_64                           1.6.3-2.el7                    base

Answer 1

Golang is currently only available in version 1.6.3 on CentOS. Therefore you should "install" it manually as described here. I assume this is what you did and therefore, you will have to uninstall it manually as well.

1. Remove the Go binary folder

To find out where you installed Go, run

which go

which will return the location of the Go binary.

Next, remove the Go-Folder (as returned by the command above), for example:

[sudo] rm -rf /usr/local/go

2. Remove extension of Environment varialbles

Finally, you should remove the extension of environment variables. Usually this is done in one of the following files

/etc/profile
~/.profile

Remove any line that either sets the GOROOT or extends the PATH environment variable, so everything that looks like this:

export PATH=$PATH:/usr/local/go/bin
export GOROOT=$HOME/go1.X
export PATH=$PATH:$GOROOT/bin
