离线安装docker-linux

离线安装docker

一.准备二进制文件

下载docker包，目前我选择的是20.10.9版本

[root@docker ~]# ls
anaconda-ks.cfg  docker-20.10.9.tgz

二.解压docker并赋予执行权限

[root@docker ~]# tar xvf 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
[root@docker ~]# chmod +x ./docker/*

将docker下的所有可执行文件拷贝到/usr/bin目录底下

[root@docker ~]# cp docker/* /usr/bin/

三.编译docker的系统服务文件

编辑/usr/lib/systemd/system/docker.service文件

[root@docker ~]# vim /usr/lib/systemd/system/docker.service
#####写入如下内容####
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.targe irewalld.service 
Wants=network-online.target 

[Service]
Type=notify
ExecStart=/usr/bin/dockerd 
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=infinity
LimitNPROC=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
RestartSec=2
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s

[Install]
WantedBy=multi-user.target

保存退出后，为docker.service文件添加执行权限：

[root@docker ~]# chmod +x /usr/lib/systemd/system/docker.service
重启守护进程
[root@docker ~]# systemctl daemon-reload

四.启动docker

[root@docker ~]# systemctl start docker
[root@docker ~]# systemctl enable  docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
[root@docker ~]# docker version
