Linux7.7离线安装Docker18.06.1
一、基础环境
1、操作系统：CentOS 7.7
[root@localhost rabbit]# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
2、Docker版本：18.06.1
下载网址：https://download.docker.com/linux/static/stable/x86_64/
3、参考官方文档地址：
https://docs.docker.com/engine/install/binaries/
二、Docker安装
1、下载并上传到服务器
略
2、解压
[root@localhost rabbit]# tar -zxvf docker-18.06.1-ce.tgz
docker/
docker/docker-containerd
docker/docker-proxy
docker/docker
docker/docker-runc
docker/dockerd
docker/docker-containerd-ctr
docker/docker-containerd-shim
docker/docker-init
#查看解压内容
[root@localhost rabbit]# cd docker/
[root@localhost docker]# ll
总用量 143620
-rwxr-xr-x. 1 user user 37589867 8月 22 2018 docker
-rwxr-xr-x. 1 user user 26393752 8月 22 2018 docker-containerd
-rwxr-xr-x. 1 user user 14725592 8月 22 2018 docker-containerd-ctr
-rwxr-xr-x. 1 user user 4173632 8月 22 2018 docker-containerd-shim
-rwxr-xr-x. 1 user user 53072264 8月 22 2018 dockerd
-rwxr-xr-x. 1 user user 764144 8月 22 2018 docker-init
-rwxr-xr-x. 1 user user 2837280 8月 22 2018 docker-proxy
-rwxr-xr-x. 1 user user 7495056 8月 22 2018 docker-runc
3、将解压出来的docker文件内容移动到 /usr/bin/ 目录下
[root@localhost rabbit]# cp docker/* /usr/bin
4、将docker注册为service
[root@localhost rabbit]# vim /etc/systemd/system/docker.service
#增加内容如下：
[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.target5、启动
#添加文件权限
[root@localhost rabbit]# chmod +x /etc/systemd/system/docker.service
#重载unit配置文件
[root@localhost rabbit]# systemctl daemon-reload
#启动Docker
[root@localhost rabbit]# systemctl start docker
#设置开机启动
[root@localhost rabbit]# systemctl enable docker.service
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /etc/systemd/system/docker.service.6、验证
#查看Docker状态
[root@localhost rabbit]# systemctl status docker
