1. 下载docker安装包

官方地址：

https://download.docker.com/linux/static/stable/x86_64/docker-20.10.9.tgz

2.解压缩

tar -zxvf docker-20.10.9.tgz

[root@centos247 docker]# tar -zxvf docker-20.10.9.tgz 
docker/
docker/containerd-shim-runc-v2
docker/dockerd
docker/docker-proxy
docker/ctr
docker/docker
docker/runc
docker/containerd-shim
docker/docker-init
docker/containerd

3. 解压的docker文件夹全部移至/usr/bin目录

cp -p docker/* /usr/bin

4. 将docker注册为系统服务

① 在/usr/lib/systemd/system/目录下，创建docker.service文件
② 编辑docker.service文件

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

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target docker.socket firewalld.service containerd.service time-set.target
Wants=network-online.target containerd.service
Requires=docker.socket

[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
# 2023-11-8 22:44:37 add -H tcp://0.0.0.0:2375  	DJCKING 
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock  -H tcp://0.0.0.0:2375 
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutStartSec=0
RestartSec=2
Restart=always

# Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
# Both the old, and new location are accepted by systemd 229 and up, so using the old location
# to make them work for either version of systemd.
StartLimitBurst=3

# Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.
# Both the old, and new name are accepted by systemd 230 and up, so using the old name to make
# this option work for either version of systemd.
StartLimitInterval=60s

# 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

# Comment TasksMax if your systemd version does not support it.
# Only systemd 226 and above support this option.
TasksMax=infinity

# 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
OOMScoreAdjust=-500

[Install]
WantedBy=multi-user.target

5. 重启生效

重启守护进程
systemctl daemon-reload
systemctl start docker
查看docker状态
systemctl status docker
设置开机启动
systemctl enable docker

查看版本 docker version

[root@centos247 docker]# docker version

二、离线安装docker-compose

1. 下载docker-compose

官方地址：

https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-linux-x86_64

2.安装

sudo mv docker-compose-Linux-x86_64 /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose -v

查看版本 docker-compose version

[root@centos247 docker]# docker-compose version
docker-compose version 1.24.1, build 4667896b
docker-py version: 3.7.3
CPython version: 3.6.8
OpenSSL version: OpenSSL 1.1.0j  20 Nov 2018

三. 在线安装

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

四.docker挂载目录更改

4.1 首次安装

vi /etc/docker/daemon.json
# 内容如下：,具体目录试自己情况而定
{
  "data-root": "/mnt/run/docker"
}

重启 systemctl restart docker

4.2 已有运行容器

如果已经有容器进行运行了，此时需要创建好具体盘符的目录，使用如下命令进行将容器拷贝到新盘里

cp -R /var/run/docker /mnt/run

再修改目录

vi /etc/docker/daemon.json

# 内容如下：,具体目录试自己情况而定
{
  "data-root": "/mnt/run/docker"
}

重启 systemctl restart docker

最后提供一些daemon.json文件内容：

{
  "registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m"
  },
  "storage-driver": "overlay2",
  "data-root": "/home/run/docker"
}
