1、安装docker

（1）在线安装

curl -sSL https://get.daocloud.io/docker | sh

（2）离线安装

参考地址：安装教程1 安装教程2 安装教程3

2.1 下载docker-20.10.23

docker-20.10.23.tgz官方下载地址

2.2 上传tgz到服务器[/data/software]，解压缩并迁移命令

# cp /data/software

# tar -zxvf docker-20.10.23.tgz

# cp -pf docker/* /usr/bin

2.3 将docker注册为系统服务

# vim /usr/lib/systemd/system/docker.service 

[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
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

2.4 执行(3)配置docker私服地址和镜像加速

2.5 启动docker

# systemctl daemon-reload

# systemctl start docker

# systemctl enable docker  // 开机启动

# docker info

（3）设置docker国内镜像加速、私服地址、镜像存储位置

# mkdir -p /data/docker/lib && mkdir /etc/docker

# vim /etc/docker/daemon.json
{
"registry-mirrors": [
	"https://hub-mirror.c.163.com/", 
	"https://mirror.ccs.tencentyun.com", 
	"https://mirror.baidubce.com"
 ],
 "insecure-registries": [
   "docker.platomix.net:10000"
 ],
 "data-root": "/data/docker/lib"
}

# systemctl start docker

2、安装docker-compose[版本号：2.15.0]

(1)上传docker-compose上传到/data/software

根据CPU内核架构([uname -m]命令可以查看内核架构)选择对应的下载地址。 aarch64下载地址 x86_64下载地址

# cd /data/software

//根据自己下载的文件名 重命名为 docker-compose
# mv docker-compose-linux-aarch64 docker-compose 或者 mv docker-compose-linux-x86_64 docker-compose

# cp docker-compose /usr/local/bin 

# chmod a+x /usr/local/bin/docker-compose
	
# ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

# docker-compose --version

(2)在线下载docker-compose

# curl -L https://get.daocloud.io/docker/compose/releases/download/v2.15.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod a+x /usr/local/bin/docker-compose

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

# ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

# docker-compose --version
