Docker 安裝準備

官方網址：https://www.docker.com/

1.Docker 安裝

sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sudo sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
sudo yum makecache fast
sudo yum -y install docker-ce
sudo systemctl start docker.service
sudo systemctl enable docker.service
sudo docker version
 

2. 配置映象加速器及更改docker的資料目錄

針對Docker客戶端版本大於 1.10.0 的使用者
您可以通過修改daemon配置檔案/etc/docker/daemon.json來使用加速器

mkdir /data
cp -ar /var/lib/docker/ /data/

vim  /etc/docker/daemon.json
i{
"registry-mirrors": ["https://un1tt4qx.mirror.aliyuncs.com"],
"graph":"/data/docker"
}

sudo systemctl daemon-reload
sudo systemctl restart docker
 

3.開啟快取收集yum安裝rpm包

vim /etc/yum.conf
.............................
keepcache=1

mkdir docker_rpm
find /var/cache/yum/x86_64/7/ -name "*.rpm" -type f |xargs -i mv {} docker_rpm/
ls docker_rpm/
tar zcf docker_rpm.tar.gz docker_rpm
scp xxxxxx
yum localinstall *.rpm -y

systemctl start docker
systemctl enable docker
docker --version
 

4.安裝docker-compose

//下載docker-compose

curl -L https://get.daocloud.io/docker/compose/releases/download/1.24.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
