How to update the Go version

System: Debian/Ubuntu/Fedora. Might work for others as well.

1. Uninstall the exisiting version

As mentioned here, to update a go version you will first need to uninstall the original version.

To uninstall, delete the /usr/local/go directory by:

bamoo456

func main() {
	cmd := exec.Command("sh", "-c", "cd ../../bin/worker; ./run.sh")
    // some command output will be input into stderr
    // e.g.
    // cmd := exec.Command("../../bin/master_build")
    // stderr, err := cmd.StderrPipe()
	stdout, err := cmd.StdoutPipe()
	if err != nil {
		fmt.Println(err)
	}

Have you ever stuck in a condition where you have to restore your mysql database from only an *.frm and *.ibd files? I have.

So what happen is somehow our mysql service is going down and can not be restarted. I try many things to no avail and getting tired of it.

And then I came across this page https://dev.mysql.com/doc/mysql-enterprise-backup/3.11/en/partial.restoring.single.html. I think probably I can just copy the *.frm and *.ibd file, wipe the current mysql data, reset the mysql, and restore those two files. Easy.

So I stupidly remove /var/lib/mysql/[schema_name], and also /var/lib/mysql/ib* file. Restart the mysql, and it start normally. Finally!
