集群环境搭建&&网盘部署

(1) 修改主机名并配置映射

# hostnamectl set-hostname master
# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.10 master
192.168.100.11 node

(2) 关闭SELinux和防火墙

# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
# setenforce 0

# systemctl stop firewalld.service
# systemctl disable firewalld.service

(3) 删除iptables防火墙规则

# iptables -F
# iptables -X
# iptables -Z
# /usr/sbin/iptables-save

(4) 配置yum源
