centos8.5离线安装docker

1、下载docker的安装文件

[https://download.docker.com/linux/static/stable/x86_64/](javascript:void(0))

2、 将下载包上传到服务器

通过各种ftp上传工具。如：FinalShell、Xftp等；

3、解压下载包

tar -zxvf docker-19.03.0.tgz

4、将解压出来的docker文件复制到 /usr/bin/ 目录下

cp docker/* /usr/bin/

5、进入/etc/systemd/system/目录,并创建docker.service文件

cd /etc/systemd/system/ touch docker.service

6、打开docker.service文件,编辑内容（复制粘贴即可）：

[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 -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
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

7、授权执行权限

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

8、重载systemd下docker.service文件

systemctl daemon-reload

9、安装完成，启动Docker

# 启动docker
systemctl start docker
# 设置开机启动
systemctl enable docker
# 查看docker状态
systemctl status docker
# 查看docker版本
docker -v
