如果需要搭建存储节点则添加机器并配置网络即可，我的所有密码设置为123
所有节点都需要操作，且操作方法一样，只写了controller一个节点的结果，其他节点照常执行
IP地址自行配置
[root@localhost ~]# hostnamectl set-hostname controller
[root@localhost ~]# bash
将默认的enforcing改为disabled
[root@controller ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
[root@controller ~]# setenforce 0
[root@controller ~]# systemctl disable --now firewalld
[root@controller ~]# cat /etc/hosts

# 加上controller和compute，如果有其他节点也写进来

我的所有密码为123，之后不写注释了，你需要修改密码的话将123改为你想设的密码就好
