CentOS 7.9 安装 Containerd-1.6.5

一、CentOS 7.9 安装 Containerd-1.6.5

地址

• https://containerd.io/downloads

在安装containerd前，我们需要优先升级libseccomp。

在centos7中yum下载libseccomp的版本是2.3的，版本不满足我们最新containerd的需求，需要下载2.4以上的。

二、CentOS 7.9 升级 libseccomp-2.5.1

地址

• https://rpmfind.net/linux/rpm2html/search.php?query=libseccomp&submit=Search+...

卸载原来的

[root@ecs-65685 ~]#  rpm -qa | grep libseccomp
libseccomp-2.3.1-4.el7.x86_64
[root@ecs-65685 ~]#
[root@ecs-65685 ~]# rpm -e libseccomp-2.3.1-4.el7.x86_64 --nodeps

wget下载

wget https://rpmfind.net/linux/centos/8-stream/BaseOS/x86_64/os/Packages/libseccomp-2.5.1-1.el8.x86_64.rpm

安装

[root@ecs-65685 software]# rpm -ivh /opt/software/libseccomp-2.5.1-1.el8.x86_64.rpm
warning: /opt/software/libseccomp-2.5.1-1.el8.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 8483c65d: NOKEY

查看当前版本

[root@ecs-65685 software]# rpm -qa | grep libseccomp
libseccomp-2.5.1-1.el8.x86_64

使用场景在Kubernetes 1.20+版本中的Containerd会用到。

三、下载安装containerd

1 官方地址：https://containerd.io/downloads

Containerd安装我们使用1.6.4版本号

containerd-1.6.1-linux-amd64.tar.gz 只包含containerd

cri-containerd-cni-1.6.4-linux-amd64.tar.gz 包含containerd以及cri runc等相关工具包，建议下载本包

wget https://github.com/containerd/containerd/releases/download/v1.6.5/cri-containerd-cni-1.6.5-linux-amd64.tar.gz

2 解压

# 直接让它给我们对应的目录给替换掉
[root@ecs-65685 software]# tar zxvf cri-containerd-cni-1.6.5-linux-amd64.tar.gz -C /

cri-containerd-cni会将我们整个containerd相关的依赖都进行下载下来。

上面的文件都是二进制文件，直接移动到对应的目录并配置好环境变量就可以进行使用了。
