三、复制二进制文件到/usr/bin/目录
四、创建用户组
五、配置相关服务配置文件
六、拷贝配置文件到指定目录
七、启动 dockerd 服务进程
八、shell脚本一键安装
一、准备 Docker CE 二进制包
https://download.docker.com/linux/static/stable/x86_64/docker-20.10.24.tgz
二、解压.tgz包
tar -zxvf docker-20.10.24.tgz
chown root:root docker/*
三、复制二进制文件到/usr/bin/目录
cp -p docker/* /usr/bin/
四、创建用户组
groupadd docker
五、配置相关服务配置文件
有三个配置文件：docker.service 、docker.socket、 containerd.service。
docker.service配置文件：
touch docker.service
vi 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
docker.socket配置文件：
touch docker.socket
vi docker.socket
[Unit]
Description=Docker Socket for the API
PartOf=docker.service
[Socket]
ListenStream=/var/run/docker.sock
SocketMode=0660
SocketUser=root
SocketGroup=docker
[Install]
WantedBy=sockets.target
containerd.service配置文件：
touch containerd.service
vi containerd.service
[Unit]
Description=containerd container runtime
Documentation=https://containerd.io
After=network.target local-fs.target
[Service]
ExecStartPre=-/sbin/modprobe overlay
ExecStart=/usr/bin/containerd
Type=notify
Delegate=yes
KillMode=process
Restart=always
RestartSec=5
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNPROC=infinity
LimitCORE=infinity
LimitNOFILE=infinity
# Comment TasksMax if your systemd version does not supports it.
# Only systemd 226 and above support this version.
TasksMax=infinity
OOMScoreAdjust=-999
[Install]
WantedBy=multi-user.target
六、拷贝配置文件到指定目录
sudo cp docker.socket /etc/systemd/system
sudo cp docker.service /etc/systemd/system
sudo cp containerd.service /etc/systemd/system
七、启动 dockerd 服务进程
systemctl enable docker.service
systemctl start docker.servicedocker version八、shell脚本一键安装
代码地址：https://gitee.com/os-lee/easy_docker
开源不易，麻烦一键三连加star
# 二进制安装（推荐）
sh install-docker.sh install# 卸载
sh install-docker.sh remove# yum安装
sh install-docker.sh yum[root@localhost easy_docker]# sh install-docker.sh install
创建解压路径
解压软件包到指定目录
docker/
docker/docker-proxy
docker/containerd-shim-runc-v2
docker/ctr
docker/docker
docker/docker-init
docker/runc
docker/dockerd
docker/containerd
docker/containerd-shim
复制docker-compose
复制二进制文件到/usr/bin/目录，创建用户组
配置镜像加速
开机自启动
