Docker安装（RPM包方式）

Docker安装（RPM包方式）

一、安装环境准备

1、操作系统要求

#1、查看内核版本
[root@nod var]# uname -r
3.10.0-957.el7.x86_64
#2、查看操作系统版本
[root@nod var]# cat /etc/os-release 
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"

CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"

#3、关闭防火墙
[root@nod var]# systemctl stop firewalld
[root@nod var]# systemctl disable firewalld
[root@nod var]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)
#4、关闭SElinux
[root@nod var]vim /etc/selinux/config
[root@nod var]# getenforce
Disabled
#5、查看iptables是否被启动
[root@nod selinux]# systemctl status iptables
#若没有安装进行iptables进行安装
[root@nod selinux]# yum -y install iptables-services
#启动iptables
[root@nod selinux]# systemctl start iptables
#设置为开机自启
[root@nod selinux]# sysatemctl enable iptables
#查看iptables的状态
[root@nod selinux]# systemctl status iptables
● iptables.service - IPv4 firewall with iptables
   Loaded: loaded (/usr/lib/systemd/system/iptables.service; enabled; vendor preset: disabled)
   Active: active (exited) since Thu 2021-12-02 10:18:29 CST; 31s ago
 Main PID: 3796 (code=exited, status=0/SUCCESS)

#清空防火墙
[root@nod selinux]# iptables -F
#保存防火墙
[root@nod selinux]# service  iptables save

#查看防火墙状态
[root@nod selinux]# iptables -nL
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

#建议更新软件包
[root@nod selinux]# yum update
#重启并使用最新的内核启动
[root@nod selinux]# shutdown -h now
#升级之后的内核版本
[root@nod ~]# uname -r
3.10.0-1160.49.1.el7.x86_64

2、判断是否存在老版本Docker进行卸载

root@nod system]# yum remove docker \
>                   docker-client \
>                   docker-client-latest \
>                   docker-common \

docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm 
docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm   

3.2、上传Docker安装包

#1、把docker安装包上传到/root/docker目录下
[root@nod ~]# mkdir docker
[root@nod ~]# cd docker/
[root@nod docker]# ll
total 19096
-rw-r--r-- 1 root root 19521288 Dec  2 18:55 docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm
-rw-r--r-- 1 root root    29108 Dec  2 18:55 docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm

#2、到/root/docker目录下执行安装
[root@nod docker]# yum -y install *

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

4、Docker卸载

#1、卸载依赖
yum remove docker-ce docker-ce-li containerd.io
#2、删除资源
rm -rf /var/lib/docker

5、Docker国内镜像

#1、创建或修改/etc/docker/daemon.json文件
[root@nod docker]# vim /etc/docker/daemon.json
{
        "registry-mirrors":["https://4jxxx3m1.mirror.aliyuncs.com"]
}

#2、加载资源，重启docker
[root@nod docker]# systemctl daemon-reload
[root@nod docker]# systemctl restart docker
#3、通过docker info查看当前镜像库
[root@nod ~]# docker info
