作为cloudinit userdata脚本运行时，go install不会在GOBIN下添加二进制文件

在安装golang之后，我尝试安装这个包: github.com/czerwonk/bird_exporter，如下所示：

    GO_VERSION=1.17.1
    curl -L https://golang.org/dl/go${GO_VERSION}.linux-amd64.tar.gz -o go${GO_VERSION}.linux-amd64.tar.gz
    tar -C /usr/local -xzf go1.17.1.linux-amd64.tar.gz
    mkdir /root/go
    export GOPATH=/root/go
    export PATH=${PATH}:/usr/local/go/bin:${GOPATH}/bin
    echo "export GOPATH=${GOPATH}" >> /root/.bashrc
    echo "export PATH=${PATH}:/usr/local/go/bin:${GOPATH}/bin" >> /root/.bashrc

我像这样安装这个包：

    BIRD_EXPORTER_VERSION=1.2.6
    go install github.com/czerwonk/bird_exporter@${BIRD_EXPORTER_VERSION}

GOBIN

    file /root/go/bin/bird_exporter 
    /root/go/bin/bird_exporter: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), not stripped
