卸载旧版本的docker 相关安装包
sudo yum remove docker \docker-client \docker-client-latest \docker-common \docker-latest \docker-latest-logrotate \docker-logrotate \docker-engine
安装最新版docker，通过以下版本下载arm版本docker包
https://download.docker.com/linux/static/stable/aarch64/
准备docker.service文件
进入到/etc/systemd/system/目录下执行vim docker.service
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd
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 the docker process if it exits prematurely
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s[Install]
WantedBy=multi-user.target首先将 docker包解压到你存放的目录
tar -xvf docker-27.3.1.tgz
将解压好docker 文件移动到 /usr/bin 目录下
cp -p docker/* /usr/bin
将 docker.service 移到 /etc/systemd/system/ 目录
cp docker.service /etc/systemd/system/
设置 docker.service 文件权限
chmod +x /etc/systemd/system/docker.service
重新加载配置文件
systemctl daemon-reload
启动docker
systemctl start docker
启动如果报错，查看一下系统日志
tail -200f /var/log/messages
启动docker
systemctl start docker
检查 Docker 是否能启动
systemctl status docker
设置 docker 开机自启
systemctl enable docker
验证安装是否成功
docker --version
配备镜像源
在/etc/docker/daemon.json
{"exec-opts": ["native.cgroupdriver=systemd"],"registry-mirrors": ["https://docker.m.daocloud.io","http://hub-mirror.c.163.com","https://docker.rainbond.cc"],"insercure-registries":["本地的IP地址:xxx"],"max-concurrent-downloads": 10,"log-driver": "json-file","log-level": "warn","log-opts": {"max-size": "10m","max-file": "3"},"data-root": "/var/lib/docker"
}
注意daemon.json和docker.service里面的insecture-registry不要重复配置，否则会报错
安装docker-compose
下载arm架构的docker-compose源码安装包
https://github.com/docker/compose/releases?page=8
到存放docker-compose的目录下执行以下命令：
mv docker-compose-linux-aarch64 /usr/bin/docker-compose
chmod +x /usr/bin/docker-compose
查看docker-compose版本
docker-compose --version
