## linux安装Docker ##

**1.linux环境查看**  
查看linux版本环境查看 uname

**2.系统版本信息查看**

> \[root@linux /\]\# uname -r  
> 3.10.0-1127.el7.x86\_64  
> \[root@linux /\]\# ^C  
> \[root@linux /\]\# 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.开始安装docker**

> 1.卸载旧的docker版本:

yum remove docker \
                      docker-client \
                      docker-client-latest \
                      docker-common \
                      docker-latest \
                      docker-latest-logrotate \
                      docker-logrotate \
                      docker-engine

> 2.需要的安装包:

yum install -y yum-utils

> 3.设置镜像仓库(默认是国外的,十分慢,换成国内的):

#国外的:
     yum-config-manager \
        --add-repo \
        https://download.docker.com/linux/centos/docker-ce.repo   #国外的镜像地址
    #国内的: 
     yum-config-manager \
        --add-repo \
        http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo  #国内的镜像地址

yum makecache fast

> 5.安装docker相关的

安装最新的版本:
    yum install docker-ce docker-ce-cli containerd.io
    安装指定版本的:
    yum install docker-ce-<VERSION_STRING> docker-ce-cli-<VERSION_STRING> containerd.io

> 6.启动docker:

systemctl start docker

> 7.查看docker是否安装成功
