centos7 安装 python3 、docker、 docker-compose 脚本

需要先yum -y install wget
centos7 一键安装python3
vi install_py3.py
python install_py3.py

安装docker shell脚本：
#!/bin/bash

echo "Installing docker..."

sudo yum remove -y docker 
                  docker-client 
                  docker-client-latest 
                  docker-common 
                  docker-latest 
                  docker-latest-logrotate 
                  docker-logrotate 
                  docker-engine && 

sudo yum install -y yum-utils 
  device-mapper-persistent-data 
  lvm2 && 

sudo yum-config-manager 
    --add-repo 
    https://download.docker.com/linux/centos/docker-ce.repo && 

sudo yum install -y docker-ce docker-ce-cli containerd.io && 

sudo systemctl enable docker && 

if [ ! -d "/etc/docker" ]; then
mkdir /etc/docker

}
EOF

sudo systemctl start docker

echo "Docker has been installed!"

安装docker-compose

#!/bin/bash

yum -y install epel-release &&  
yum -y install python-pip &&  
pip install --upgrade pip &&  
yum -y install python-devel python-subprocess32 &&  
find / -name *subpro*.egg-info &&  
find / -name *subpro*.egg-info |xargs rm -rf &&  
pip install docker-compose &&  
docker-compose version &&  
echo "docker-compose install successful"
