sudo mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#

[base]
name=CentOS-$releasever - Base
baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/os/$basearch/
#mirrorlist=http://mirrorlist.centos.org/"htmlcode">

yum clean all && yum makecache && yum update


但是yum源的软件还是太少了, 比如我想安装只有 python-pip 都做不到
 
第二步: 安装阿里epel源


yum -y install epel-release
wget -O /etc/yum.repos.d/epel-7.repo http://mirrors.aliyun.com/repo/epel-7.repo
# 刷新yum源
yum clean all && yum makecache && yum update


 
 
至此, 我们可以愉快的安装python-pip了, yum install python-pip 


 
第三步: 安装docker和docker-compose
1. 安装docker


# 通过yum源安装docker
sudo yum -y install docker
# 启动docker
sudo systemctl start docker
# 开机自启
sudo systemctl enable docker


 
2. 安装docker-compose


sudo pip install docker-compose
# 安装成功后查看
sudo docker-compose --version


 
3. Docker 中国官方镜像加速


修改/etc/docker/daemon.json, 加入以下配置




{
"registry-mirrors": ["https://registry.docker-cn.com"]
}




重启docker




sudo service docker restart
