描述
由于机器在内网无法使用yum或rpm安装docker，所以使用的是离线安装。
下载docker离线包地址
https://download.docker.com/linux/static/stable/x86_64/
注：可自行选择版本下载
1、安装docker
1、下载 Docker 二进制文件（离线安装包）
wget https://download.docker.com/linux/static/stable/x86_64/docker-18.06.3-ce.tgz
2、上传离线包
通过Xshell、FTP等工具上传至内网服务器
3、解压安装包
tar -zxvf docker-18.06.3-ce.tgz
4、将docker 相关命令拷贝到 /usr/bin
cp docker/* /usr/bin/
5、docker注册成系统服务
cat /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
6、添加执行权限
chmod +x /etc/systemd/system/docker.service
7、重新加载配置文件
systemctl daemon-reload
8、启动服务
systemctl start docker
9、设置开机自启
systemctl enable docker.service
10、查看状态
systemctl status docker
11、查看Docker版本
docker -v
