二进制安装docker

二进制部署docker

简介

​ 使用二进制部署docker有很多好处例如内网服务器中不可能让每台服务器下载这样会占用网络资源。所以使用二进制版本再结合自动化工具来部署或升级省时又省力

安装

1、下载二进制包

这里在阿里云镜像站点下载https://mirrors.aliyun.com/docker-ce/linux/static/stable/x86_64/

[root@node01 src]# wget https://mirrors.aliyun.com/docker-ce/linux/static/stable/x86_64/docker-19.03.13.tgz

2、解压下载好的二进制包

[root@node01 src]# tar xf docker-19.03.13.tgz

3、查看解压后的文件

[root@node01 src]# ll
total 59308
drwxrwxr-x 2 1000 1000      138 May 15 08:29 docker
-rw-r--r-- 1 root root 60730088 Oct 21 09:47 docker-19.03.13.tgz
[root@node01 src]# ll docker
total 195504
-rwxr-xr-x 1 1000 1000 32751272 May 15 08:29 containerd
-rwxr-xr-x 1 1000 1000  6012928 May 15 08:29 containerd-shim
-rwxr-xr-x 1 1000 1000 18194536 May 15 08:29 ctr
-rwxr-xr-x 1 1000 1000 61113382 May 15 08:29 docker
-rwxr-xr-x 1 1000 1000 68874208 May 15 08:29 dockerd
-rwxr-xr-x 1 1000 1000   708616 May 15 08:29 docker-init
-rwxr-xr-x 1 1000 1000  2928514 May 15 08:29 docker-proxy
-rwxr-xr-x 1 1000 1000  9600696 May 15 08:29 runc

4、存放位置

拿到这么多可执行程序后，但是这些文件要搁哪比较合适呢，就要看你的docker.service文件里怎么定义了，这里还是安装官方的默认路径来放,存放到/usr/bin下

[root@node01 src]# cd docker/
[root@node01 docker]# cp -a ./* /usr/bin/
# 在输入docker命令时跟docker有关的命令
[root@node01 docker]# docker
docker        dockerd       docker-init   docker-proxy

5、编写启动文件

需要这三个文件containerd.service、docker.service、docker.socket 可以从其他已经安装好的机器上拷贝过来

6、启动docker

一切都准备就绪之后可以启动docker了

[root@node01 system]# systemctl daemon-reload
[root@node01 system]# systemctl start containerd
[root@node01 system]# systemctl start docker
A dependency job for docker.service failed. See 'journalctl -xe' for details.
[root@node01 system]# systemctl status docker
