一、下载源码包

下载地址：https://download.docker.com/linux/static/stable/x86_64/

mkdir -p /opt/src && cd /opt/src
wget https://download.docker.com/linux/static/stable/x86_64/docker-20.10.17.tgz

二、安装docker

tar -xf docker-20.10.17.tgz
cp docker/* /usr/bin

三、创建配置文件

mkdir /etc/docker
 
## 配置国内的镜像源，加速镜像拉取
cat > /etc/docker/daemon.json << EOF
{
  "registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"]
}
EOF

四、systemd管理docker

1、生成配置文件

cat > /usr/lib/systemd/system/docker.service << EOF
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target
[Service]
Type=notify
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
[Install]
WantedBy=multi-user.target
EOF

2、启动并设置开机自启

systemctl daemon-reload
systemctl start docker
systemctl enable docker
docker --version

五、附上一键安装脚本 

## 下载安装包，可自行调整版本
mkdir -p /opt/src && cd /opt/src
wget https://download.docker.com/linux/static/stable/x86_64/docker-20.10.17.tgz
## 安装docker
tar -xf docker-20.10.17.tgz
cp docker/* /usr/bin
## 创建配置文件
mkdir /etc/docker
 
## 配置国内的镜像源，加速镜像拉取
cat > /etc/docker/daemon.json << EOF
{
  "registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"]
}
EOF
## 生成systemd配置文件
cat > /usr/lib/systemd/system/docker.service << EOF
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target
[Service]
Type=notify
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
[Install]
WantedBy=multi-user.target
EOF
## 启动并设置开启自启
systemctl daemon-reload
systemctl start docker
systemctl enable docker
docker --version
