Rancher安装

前言

本文介绍如何在centos 7.5上安装Rancher

设置主机名

hostnamectl set-hostname node1

如果有多台主机，可根据自己的情况设置

操作步骤

yum install -y wget 
wget https://download.docker.com/linux/static/stable/x86_64/docker-17.03.2-ce.tgz
chmod +x docker/* 
cp docker/* /usr/local/bin

cd /usr/lib/systemd/system
cat > docker.service <<"EOF"
