Redhat OS安裝docker-ce及docker-compose步驟

1、更換repo源

sudo yum install -y yum-utils
# 下面這兩個視具體情況執行
# sudo yum install -y device-mapper-persistent-data lvm2
# sudo yum-config-manager --enable rhel-7-server-extras-rpms
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum makecache fast
           

2、安裝container-selinux包

sudo yum install -y http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.107-1.el7_6.noarch.rpm
           

3、安裝docker-ce

sudo yum install docker-ce-18.06.3.ce-3.el7.x86_64
# 如果需要選擇版本可以輸入如下指令檢視版本
# yum list docker-ce --showduplicates|sort -r
# yum install docker-ce-<version>-<release>
           

4、設定啟動

sudo systemctl start docker
sudo systemctl enable docker
           

5、檢視docker版本并測試

docker -v

#Test your Docker CE installation:
sudo docker run hello-world
           

6、安裝docker-compose

sudo pip install docker-compose
           

如果pip也沒有，那麼先按照如下執行安裝pip并更新python包

# install python-pip
wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

sudo yum install ./epel-release-latest-7.noarch.rpm
sudo yum install -y python-pip
# upgrade your Python packages:
sudo yum upgrade python*
