无法在CentOS8容器上打开‘/lib64 64/ld-linux-x86-64.so.2’

Question

我在M1 Mac上，试图在CentOS 8码头容器中创建并构建一个golang rpm包。

我在上面安装了：

1. wget https://dl.google.com/go/go1.13.4.linux-amd64.tar.gz
2. sudo tar -C /usr/local -xf go1.13.4.linux-amd64.tar.gz
3. Adding export PATH=$PATH:/usr/local/go/bin to ~/.bash_profile
4. source ~/.bash_profile

但是，当我运行go version时，我会得到错误：

qemu-x86_64:无法打开‘/lib64 64/ld-linux-x86-64.so.2’：没有这样的文件或目录

我已经在网上看过了，但是那些有类似错误的人，似乎处在完全不同的情况下，在这种情况下我无法复制。我能做些什么来在这个CentOS容器上实际安装golang呢？

Answer 1

希望你能享受集装箱之旅，

关于您的错误消息，您可以检查以下内容：qemu-x86_64: Could not open '/lib64/ld-linux-x86-64.so.2': No such file or directory

但我也有一些建议，这可能对你有帮助:既然我没有你的文件，我试着用这个：

FROM centos:8

RUN yum -y update && yum -y install wget
RUN wget https://dl.google.com/go/go1.13.4.linux-amd64.tar.gz
RUN sudo tar -C /usr/local -xf go1.13.4.linux-amd64.tar.gz
RUN echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.bash_profile
RUN source ~/.bash_profile

让我们构建它：

❯ docker build -t so-go-version-centos8 .

问题是，对于centos8停靠映像，我无法更新或安装任何内容：(https://serverfault.com/questions/1091791/the-latest-centos8-docker-image-cannot-run-yum)

因此，我决定避免系统更新和wget的安装，并使用dockerfile命令( ADD和COPY之间的区别是，我们可以使用ADD直接从URL复制东西，而不仅仅是从主机文件系统)，并使用dockerfile命令将go路径添加到$PATH env变量，下面是我的df：

FROM centos:8

ADD https://dl.google.com/go/go1.13.4.linux-amd64.tar.gz .
RUN tar -C /usr/local -xf go1.13.4.linux-amd64.tar.gz
ENV PATH=$PATH:/usr/local/go/bin

让我们构建它：

效果很好。

Centos8对接映像是有限的，因为我不能安装我所需要的，所以你可以用centos:7对接映像代替它。

解决方案2:如@Para建议的那样尝试yum安装golang，您也可以使用yum直接安装golang，但是"yum -y golang“将无法工作。所以我们必须手动安装它，就像我们所做的那样。

solution3:您可以直接使用正式的高丽码头图像，即：

❯ docker run -it golang:buster
root@ed9f31e4a45a:/go# go version
go version go1.18.1 linux/amd64
root@ed9f31e4a45a:/go#

希望这能帮到你，我猜。
