    The commands are:

            download    download modules to local cache
            edit        edit go.mod from tools or scripts
            graph       print module requirement graph
            init        initialize new module in current directory
            tidy        add missing and remove unused modules
            vendor      make vendored copy of dependencies
            verify      verify dependencies have expected content
            why         explain why packages or modules are needed

cd glusterfs-benchmark 
go mod init glusterfs-benchmark 
//会在 lusterfs-benchmark目录中  生成go.mod的文件
