Linux离线安装Docker

1.从官方下载Docker安装包并上传至虚拟机

https://download.docker.com/linux/static/stable/x86_64/

2.解压安装包

tar -xvf docker-18.06.1-ce.tgz

3.将解压出来的docker文件内容移动到 /usr/bin/ 目录下

cp docker/* /usr/bin/

4.将docker注册为service服务

vim /etc/systemd/system/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

5.启动docker

chmod +x /etc/systemd/system/docker.service

systemctl daemon-reload
systemctl start docker            #启动Docker
systemctl enable docker.service            #设置开机自启

6.验证

systemctl status docker            #查看Docker状态
docker -v            #查看Docker版本

Tips:

①忽略证书配置

ExecStart=/usr/bin/dockerd --insecure-registry Docker仓库IP:Docker端口号

②启动容器报错：

/usr/bin/docker-current: Error response from daemon: shim error: docker-runc not installed on system.

解决：

ln -s /usr/libexec/docker/docker-runc-current /usr/bin/docker-runc
