docker-compose安装请参考：https://www.xmmup.com/linuxanzhuang-docker-compose.html
一、安装简介
Docker 运行在 CentOS 7 上，要求系统为64位、系统内核版本为 3.10 以上。CentOS 7 的内核一般都是3.10的，而CentOS 6.X 的内核一般都是2.6，在2.6的内核下，Docker运行会比较卡，所以一般会选择升级到3.10版本。
二、在CentOS 7上安装Docker常用命令
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 | -- 1、卸载掉旧版本的 Docker： yum remove -y docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine -- 关闭SELINUX sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/selinux/config -- 一定要重启OS! -- 查询返回disabled getenforce sestatus -- 2、执行以下安装命令去安装依赖包： yum install -y yum-utils device-mapper-persistent-data lvm2 yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo yum -y install docker-ce docker-ce-cli containerd.io -- 若执行报错，则配置yum源 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo -- 或一键安装Docker： curl -fsSL get.docker.com -o get-docker.sh sh get-docker.sh systemctl start docker systemctl status docker -- 检查版本 docker version docker info -- docker命令补全 yum install -y bash-completion chmod 755 /usr/share/bash-completion/bash_completion sh /usr/share/bash-completion/bash_completion source /usr/share/bash-completion/completions/docker |
三、执行过程：
1、卸载旧版本
