視頻鏈接：二進(jìn)制安裝containerd及docker

1.?安裝containerd
> [下載頁](https://github.com/containerd/containerd/releases)
```shell
## 先在ceph01上操作
## 直接下載：cri-containerd-1.7.2-linux-amd64.tar.gz，該包里面包含了containerd、 ctr、crictl、containerd-shim等二進(jìn)制文件，還有啟動命令等，只要在/下解壓即可。
# tar xf cri-containerd-1.7.2-linux-amd64.tar.gz -C /

# cat > /etc/crictl.yaml << EOF
runtime-endpoint: unix:///var/run/containerd/containerd.sock
image-endpoint: unix:///var/run/containerd/containerd.sock
timeout: 10
debug: false
EOF

## 生成containerd配置文件
# mkdir /etc/containerd
# containerd config default > /etc/containerd/config.toml

## 修改 /etc/containerd/config.toml
## 把SystemdCgroup = false修改為：SystemdCgroup = true
# vi /etc/containerd/config.toml

## 調(diào)整日志
max_container_log_line_size = 163840
## 用于從安全上下文中提取設(shè)備所有權(quán)信息，kubevirt cdi依賴該參數(shù)，不設(shè)置該參數(shù)可能出現(xiàn)無權(quán)限
device_ownership_from_security_context = true
SystemdCgroup = true

```
> 修改/etc/systemd/system/containerd.service，將`LimitNOFILE=infinity`改為`LimitNOFILE=655360`

```shell

# systemctl enable containerd && systemctl restart containerd
## 使用 crictl info 查看配置是否生效

## 其他節(jié)點只需將相關(guān)文件拷貝過去啟動即可
# 在ceph01上操作
# for i in {2..5};do scp -rp /usr/local/bin ceph0$i:/usr/lobal/;scp -rp /usr/local/sbin ceph0$i:/usr/lobal/;scp /etc/containerd ceph0$i:/etc/; scp /etc/systemd/system/containerd.service ceph0$i:/etc/systemd/;done
## 在ceph02-05上操作
# systemctl daemon-reload && systemctl enable containerd && systemctl restart containerd

```
2. 安裝docker
```shell
## 先在ceph01上操作
1). 下載docker安裝包 https://download.docker.com/linux/static/stable/x86_64/docker-20.10.23.tgz
2). 解壓
# tar xf docker-20.10.23.tgz
3). 需要用到的二進(jìn)制文件包括：docker 和 dockerd，拷貝到 /usr/bin/目錄下即可。
# mv docker/docker* /usr/bin/
4). 創(chuàng)建 docker 用戶 useradd -s /sbin/nologin docker ? # 如果docker組存在，則使用 useradd -s /sbin/nologin docker -g docker
5). 啟動的配置文件 docker.serivce 和 docker.socket 拷貝到 /usr/lib/systemd/system/，daemon.json文件放到/etc/docker目錄
# cat > /usr/lib/systemd/system/docker.service ?<<EOF

# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
