yum install -y docker

 

配置docker工作目录到数据盘

rm -rf /var/lib/docker

mkdir /data/docker

ln -s /data/docker /var/lib/docker

 

开机自启动docker

systemctl enable docker.service

 

开始初始化安装

kubeadm init

 

[preflight] This might take a minute or two, depending on the speed of your internet connection

等待中

 

centos7 查看docker 系统日志

journalctl -u docker.service
