一、yum安装指定版本docker-ce
docker RPM包官方网址：/linux/centos/7/x86_64/stable/Packages/
docker tar包官方网址：/linux/static/stable/x86_64/
1、配置本地以及网络yum源
#配置本地yum源
cd /etc//
#判断光盘是否挂载
[ -d /media/cdrom ] || mkdir /media/cdrom
mount | grep sr0 &> /dev/null
[ $? -eq 0 ] || mount /dev/sr0 /media/cdrom
echo "光盘已挂载"
#安装使用包
yum -y install wget net-tools psmisc gcc gcc-c++ make unzip which
mv
#配置网络yum源
[ -f ] || wget http://mirrors./.help/
[ -f ] || wget /repo/
[ -f ] || wget /repo/
[ -f ] || wget /repo/
[ -f ] || wget /repo/
yum clean all && yum makecache
yum install -y yum-utils
2、配置docker源以及yum安装
- 卸载旧版本
yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine
- 安装所需软件包
#yum-utils提供了yum-config-manager 效用，并device-mapper-persistent-data和lvm2由需要 devicemapper 存储驱动程序
yum install -y yum-utils
yum install -y device-mapper-persistent-data lvm2
- 配置docker源
yum-config-manager --add-repo /docker-ce/linux/centos/
yum clean all
yum makecache
- 查询可安装版本
yum list docker-ce --showduplicates | sort -r
- 安装docker-ce-19.03.5
yum -y install docker-ce-19.03.5 docker-ce-cli-19.03.5
- 启动docker
systemctl start docker
- 检查版本
docker version

GitCommit: fec3683
3、配置阿里云加速
[root@localhost images]# cat /etc/docker/
{
"data-root": "/data/docker",
"exec-opts": ["=systemd"],
"registry-mirrors": ["."], #国内镜像源
"insecure-registries": [":5000"], #私有仓库
"log-driver": "json-file",
"log-opts": {
"max-size": "100m", #每个容器日志文件大小
"max-file": "10" #最多生成的文件数
}
}
二、二进制安装docker
1.下载docker tar包
wget /linux/static/stable/x86_64/docker-19.03.
2.解压
tar xf docker-19.03.
cd docker
ll ./
[root@localhost docker]# ll
总用量 204696

-rwxr-xr-x 1 cka cka 8649800 10月 8 2019 runc
3.拷贝命令到/usr/bin/
cp docker/* /usr/bin/
PS:因为启动文件中的命令取自/usr/bin
**查看docker版本**
**docker version**
[root@localhost ~]# docker version
Client: Docker Engine - Community
Version: 19.03.3
API version: 1.40
Go version: go1.12.10
Git commit: a872fc2f86
Built: Tue Oct 8 00:54:52 2019
OS/Arch: linux/amd64
Experimental: false
**Cannot connect to the Docker daemon at unix:///var/run/. Is the docker daemon running?**
表示找不到，docker服务未启动
4.准备service启动文件
vim /lib/systemd/system/

5.启动docker
>chmod +x /lib/systemd/system/
systemctl daemon-reload //重载systemd下 文件
systemctl start docker //启动Docker
systemctl enable //设置开机自启
