前言：
有些机器没法联网，但是需要使用 docker 服务，所以就需要离线安装 docker。
一、 获取安装包
安装包下载地址：https://download.docker.com/linux/static/stable/x86_64/
从中选择一个比较稳定的版本，下载后并上传到服务器
二、 安装docker
1. 解压 docker 压缩文件到 /usr/bin/ 目录下
tar -xvf docker-18.06.1-ce.tgz
cp docker/* /usr/bin/
2. 准备 docker.service 文件
[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.target3. docker.service 文件拷贝到 /etc/systemd/system/ 目录，并给与执行权限
cp docker.service /etc/systemd/system/
chmod +x /etc/systemd/system/docker.service4. 启动 docker 服务
systemctl daemon-reload #重新加载配置文件
systemctl start docker #启动Docker
systemctl enable docker.service #设置开机自启5. 验证 docker 服务状态
systemctl status docker版权声明：本文内容由互联网用户自发贡献，该文观点仅代表作者本人。本站仅提供信息存储空间服务，不拥有所有权，不承担相关法律责任。如发现本站有涉嫌侵权/违法违规的内容， 请发送邮件至 举报，一经查实，本站将立刻删除。
