环境准备
准备一台虚拟机，请参照Kubernetes基于Centos7构建基础环境（一）
一、 检查是否之前安装过docker，如果有则清除docker环境
[root@master /]# sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine
Loaded plugins: fastestmirror
No Match for argument: docker
No Match for argument: docker-client
No Match for argument: docker-client-latest
No Match for argument: docker-common
No Match for argument: docker-latest
No Match for argument: docker-latest-logrotate
No Match for argument: docker-logrotate
No Match for argument: docker-engine
No Packages marked for removal
[root@master /]#
# 删除其安装的文件夹
[root@master /]# rm -rf /etc/systemd/system/docker.service.d
[root@master /]# rm -rf /var/lib/docker
[root@master /]# rm -rf /var/run/docker
[root@master /]# rpm -qa | grep docker
[root@master /]# yum remove -y docker-*二、 安装yum、docker环境依赖
- 见到Complete!，则安装成功
[root@localhost /]# sudo yum install -y yum-utils device-mapper-persistent-data lvm2

[root@master /]#五、 启动docker
[root@master /]# sudo systemctl restart dockerroot为登录用户名称，根据自己机器登录名称设定
[root@master /]# sudo usermod -aG docker root
[root@master /]#六、 设置docker镜像下载源，指定cgroup=systemd驱动
- 查看/etc/docker下是否有daemon.json文件，如果有手动修改，如果没有则直接执行如下命令
[root@master /]# cd /etc/docker/
[root@localhost docker]# ls
key.json
[root@master docker]#- 增加docker配置，并查看配置
- 通过https://1mbc3b4s.mirror.aliyuncs.com的获取 阿里云镜像地址，并写入daemon.json文件中
[root@master /]# sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://1mbc3b4s.mirror.aliyuncs.com"],
"exec-opts": ["native.cgroupdriver=systemd"]
}
EOF
# 查看文件写入情况
[root@master docker]# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://1mbc3b4s.mirror.aliyuncs.com"],
"exec-opts": ["native.cgroupdriver=systemd"]
}
[root@master docker]#七、设置网桥
- 设置网桥后让其永久生效
# 设置网桥，增加如下代码
[root@master /]# vi /etc/sysctl.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
# 使其永久生效
[root@master /]# sysctl -p八、重启docker
[root@master /]# sudo systemctl daemon-reload && sudo systemctl restart docker九、 查看docker是否安装成功
这里可以看到docker的版本为19.03.11，增加了docker0网络

[root@master /]#十、 设置docker开机启动
[root@master /]# sudo systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
[root@master /]#十一、 安装docker-compose（墙裂建议） docker-compose安装文档地址
- 下载docker-compose
[root@master /]# sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
