最终效果

首先你得有一个Centos7的环境

我直接用VirtualBox虚拟了一个Centos7(mini包)

#连接ssh
#替换yum库
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum makecache

#升级renguanyu
vim /etc/sudoers

#如果是多节点,需要配置完ip后重启网络
vim /etc/sysconfig/network-scripts/ifcfg-enp0s3
service network restart

#安装ftp服务
sudo yum install vsftpd
sudo systemctl start vsftpd.service
sudo systemctl status vsftpd.service

#配置jdk
sudo vim /etc/profile
sudo source /etc/profile

export JAVA_HOME=/modules/jdk1.7.0_79
export PATH=$PATH:$JAVA_HOME/bin

#关闭防火墙
sudo systemctl stop firewalld.service
sudo systemctl disable firewalld.service

# 设置时区
timedatectl set-timezone Asia/Shanghai

# 设置时间
timedatectl set-time 15:26:58

# 修改主机名
hostnamectl --static set-hostname master

#配置host
sudo vi /etc/hosts

#ssh免密登陆
ssh-keygen
ssh-copy-id master
ssh-copy-id slave1
ssh-copy-id slave2

#桥接模式-手动配置IP
