EC2 实例 t2.micro 无法安装 docker

Question

我的内核版本：

[ec2-user@ip-172-31-15-171 ~]$ uname -a
Linux ip-172-31-15-171 4.14.158-101.185.amzn1.x86_64 #1 SMP Tue Dec 24 03:25:32 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

我试过了，但只得到：

[ec2-user@ip-172-31-15-171 ~]$ sudo yum install -y docker

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我google了很多，有人说ami不支持systemctl。我不知道弄清楚。 对于container-selinux，我试过这个，但它也不起作用。

sudo yum install -q -y http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.107-1.el7_6.noarch.rpm

我也试过amazon official document提供的命令

[ec2-user@ip-172-31-15-171 ~]$ sudo amazon-linux-extras install docker
sudo: amazon-linux-extras: command not found

尝试安装它：

[ec2-user@ip-172-31-15-171 ~]$ sudo yum install -y amazon-linux-extras

No package amazon-linux-extras available.

没有包，这个实例有什么问题！

沮丧。希望对您有所帮助。

Answer 1

问题的最可能原因是使用了 Amazon Linux 1 (amzn1)。 Amazon Linux 1 使用 sysvinit，而不是 systemd。

推荐的解决方案是使用支持systemd的Amazon Linux 2
