记录 Docker 的学习过程 （安装准备篇）

docker 通过内核来实现 特点是效率高

1. centos7 三台(推荐2c 4g 最低 1c1g)
2. 关闭防火墙 selinux
3. 做好主机名解析，三台能互相ping通主机名
host参考文件
192.168.56.11 linux-node1.example.com linux-node1
192.168.56.12 linux-node2.example.com linux-node2
192.168.56.13 linux-node3.example.com linux-node3

4.时间同步
wget https://download.docker.com/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo

yum -y install docker-ce
yum -y install python-pip
pip install docker-compose

systemctl enable docker.service
systemctl start docker.service
