##二：系统环境初始化

2.1: 系统环境介绍

系统：CentOS7.5X64

cat /etc/hosts 

192.168.20.111  NN01.yl.com    NN01 
192.168.20.112  SN01.yl.com    SN01

2.2：无密钥登录配置

做root用户无密钥认证

 ssh-keygen ---一直敲回车到最后

 cat id_rsa.pub >> authorized_keys 

 将所有的公钥导入authorized_keys  分发到 所有的 机器的.ssh/ 下面

 然后测试

2.3:关闭 firewalld，iptables 与 selinux

所有节点都要配置：

yum install -y firewall* iptable* 

  (1) 关闭firewalld

 systemctl stop firewalld.service
 systemctl disable firewalld.service

 (2) 关闭iptables 
 iptables -F
 systemctl stop iptables.service 
 service iptables save
 systemctl disable iptables.service 

 (3) 禁用 selinux 

  sed -i ‘/SELINUX/s/enforcing/disabled/‘ /etc/selinux/config  
  setenforce 0
  getenforce 0
  sestatus

  重启机器

  reboot
