一、yum安装，使用rpm安装包和相关依赖

1.1 准备rpm安装包

1）在一台与目标系统版本一致的可以联网的CentOS7.9服务器上下载安装包与相关依赖

## 安装yum-utils包，添加docker yum源
sudo yum install -y yum-utils
sudo yum-config-manager \--add-repo \http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

2)下载操作

## 下载打包docker
sudo yum install --downloadonly --downloaddir=/opt/docker-23.0.4 docker-ce-23.0.4-1.el7 docker-ce-cli-23.0.4-1.el7 containerd.io docker-buildx-plugin docker-compose-plugin
sudo tar cf docker-23.0.4.tar.gz /opt/docker-23.0.4

或者执行如下的下载操作

yumdownloader --resolve --destdir=/opt/docker-23.0.4 docker-ce-23.0.4-1.el7 docker-ce-cli-23.0.4-1.el7 containerd.io docker-buildx-plugin docker-compose-plugin
sudo tar cf docker-23.0.4.tar.gz /opt/docker-23.0.4

通过 yum 命令的 Yumdownloader 插件下载 RPM 软件包及其所有依赖包。

软件包保存位置：

默认，将会下载软件包到当前目录下

yumdownloader --resolve(可选，意为下依赖包) --destdir=软件存放位置 (可选) 软件包名
例子：
yumdownloader --resolve --destdir=/opt/nginx nginx

1.2 将docker-23.0.4.tar.gz上传至/opt目录下

1)执行解压命令

tar -xvf docker-23.0.4.tar.gz

2)安装rpm包

yum install  /opt/docker-23.0.4/*.rpm

3)测试安装是否成功，查看docker版本

docker -v

4)启动docker

systemctl start docker

5)设置开机自启

systemctl enable docker

6)查看docker状态

systemctl status docker

二、二进制文件方式安装

1）将docker-23.0.4.tgz上传至/opt目录下

解压缩文件

tar -zxvf docker-23.0.4.tgz

将docker文件移动至/usr/bin目录

cp -p docker/* /usr/bin

2)将docker注册为系统服务

vi /usr/lib/systemd/system/docker.service

docker.service文件内容

[Unit]
Description=Docker Application Container Engine
Documentation=http://docs.docker.com
After=network.target docker.socket
[Service]
Type=notify
EnvironmentFile=-/run/flannel/docker
WorkingDirectory=/usr/local/bin
ExecStart=/usr/bin/dockerd \-H tcp://0.0.0.0:4243 \-H unix:///var/run/docker.sock \--selinux-enabled=false \--log-opt max-size=1g
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
Restart=on-failure
[Install]
WantedBy=multi-user.target

3）重启操作，启动docker设置为开机启动

systemctl daemon-reload
systemctl start docker
systemctl enable docker

三、安装docker-compose

将docker-compose-linux-x86_64上传至/opt

1）移动文件

cp /opt/docker-compose-linux-x86_64 /usr/local/bin/docker-compose

2）授予执行权限

chmod +x /usr/local/bin/docker-compose

3）验证查看docker-compose版本

docker-compose -v
