18年搞了一阵docker，当时模糊的使用，现在竟然忘得干干净净。。。。
1，docker的基本概念
镜像 Image，类似于一个已经部署好的系统的一个压缩文件；
容器 Container，镜像解压开就可以运行，运行的时候就是容器，是镜像运行时的实体；
仓库 类似于bintray，maven之类的，存放各种制作好的镜像。https://hub.docker.com/
2，ubuntu使用官方脚本自动安装
$ curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
# Executing docker install script, commit: 3d8fe77c2c46c5b7571f94b42793905e5b3e42e4
+ sudo -E sh -c 'apt-get update -qq >/dev/null'
+ sudo -E sh -c 'DEBIAN_FRONTEND=noninteractive apt-get install -y -qq apt-transport-https ca-certificates curl gnupg >/dev/null'
+ sudo -E sh -c 'curl -fsSL "https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg" | apt-key add -qq - >/dev/null'
Warning: apt-key output should not be parsed (stdout is not a terminal)
+ sudo -E sh -c 'echo "deb [arch=arm64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu bionic stable" > /etc/apt/sources.list.d/docker.list'
+ sudo -E sh -c 'apt-get update -qq >/dev/null'
+ '[' -n '' ']'
+ sudo -E sh -c 'apt-get install -y -qq --no-install-recommends docker-ce >/dev/null'
E: 无法修正错误，因为您要求某些软件包保持现状，就是它们破坏了软件包间的依赖关系。

想到了昔日被Ubuntu依赖支配的恐惧。。。。

这个问题呀。。。。
3，centos7 安装jdk
省事的来，直接上yum
-sh-4.2$ yum search jdk
[root@localhost senrsl]# yum install java-1.8.0-openjdk.aarch64
[root@localhost senrsl]# java -version
openjdk version "1.8.0_282"
OpenJDK Runtime Environment (build 1.8.0_282-b08)
OpenJDK 64-Bit Server VM (build 25.282-b08, mixed mode)
[root@localhost senrsl]#
多简单。。。。
4，安装Tomcat
[root@localhost senrsl]# curl -O https://ftp.wayne.edu/apache/tomcat/tomcat-10/v10.0.2/bin/apache-tomcat-10.0.2.tar.gz
% Total % Received % Xferd Average Speed Time Time Time Current

apache-tomcat-10.0.2.tar.gz
[root@localhost senrsl]# tar -zxvf apache-tomcat-10.0.2.tar.gz
apache-tomcat-10.0.2/conf/
5，部署clock到主页
同前
6，centos 安 docker
[root@localhost senrsl]# curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
sudo usermod -aG docker your-user
Remember that you will have to log out and back in for this to take effect!
WARNING: Adding a user to the "docker" group will grant the ability to run
containers which can be used to obtain root privileges on the
docker host.
Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
for more information.
