1.配置源

#下载阿里云的yum源
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
#安装基本的软件
yum install wget jq psmisc vim net-tools telnet yum-utils device-mapper-persistent-data lvm2 git -y
#添加阿里的docker镜像源，使用其中的containerd软件
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

2.安装containerd和crictl-tools

#查看containerd软件包
yum list containerd --showduplicates | sort -r
#安装最新的containerd和cri-tools,crictl和ctr是containerd的管理命令行工具
yum install containerd  crictl-tools -y
 
containerd config default > /etc/containerd/config.toml
systemctl start containerd
systemctl enable containerd
 
# 修改cgroups为systemd
sed -i 's#SystemdCgroup = false#SystemdCgroup = true#' /etc/containerd/config.toml
systemctl daemon-reload
systemctl restart containerd

注意

如果出现以下错误

containerd安装_unix

 

解决方案
