一、引言
为了实现离线安装docker-18.03.1-ce这个想法,我遍寻网络,什么 RPM 搜索大法啦,yum localinstall 方法啦,都是复杂到不行。
直接上网址:
Install Docker CE from binaries (官方文档:通过二进制包安装 docker 社区版)
友情提示:访问该网页需要科学上网:)
这里,我把当前最新(2018-05-24)的 docker-18.03.1-ce 上传到了百度云,以方便大家下载使用:
简单介绍下安装步骤:
1. 通过 FileZilla 等文件传输工具将 docker-18.03.1-ce.tar 放到用户目录下,并移动到该目录执行下述命令解压二进制包
$ tar xzvf docker-18.03.1-ce.tar
2. 将解压出来的 docker 文件所有内容移动到/usr/bin/目录下
$ sudo cp docker/*/usr/bin/
3. 开启 docker 守护进程(这个与常规安装方式不一样)
$ sudo dockerd &
4. 现在你可以尝试着打印下版本号,试着看看 images,看看 info,看看容器了
$ sudo docker images
$ sudo docker ps -a
$ sudo docker --version
$ sudo docker info
都没有问题,则表示安装成功:)
至此,完美撒花!!!
将以下文件放入 /usr/lib/systemd/system/docker.service 中,就可使用service docker restart/stop 等操作来启停docker
