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.service  docker version

八、shell脚本一键安装

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 Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /etc/systemd/system/docker.service.
