云计算：OpenStack 分布式架构添加NFS存储（单控制节点与多计算节点）

一、实验

1.环境

2.安装并配置NFS节点

3.安装并配置存储节点storage02

4.使用NFS存储

一、实验

1.环境

(1) 主机

表1 主机

|------------|-------|-----------------|-----|
| 主机 | 架构 | IP | 备注 |
| controller | 控制节点 | 192.168.204.210 | 已部署 |
| compute01 | 计算节点1 | 192.168.204.211 | 已部署 |
| compute02 | 计算节点2 | 192.168.204.212 | 已部署 |
| storage01 | 存储节点1 | 192.168.204.221 | 已部署 |
| storage02 | 存储节点2 | 192.168.204.222 | |
| nas | nfs节点 | 192.168.204.229 | |

（2）官网

OpenStack Docs: OpenStack Installation Guide for Red Hat Enterprise Linux and CentOS

（3）存储节点2网络

①存储节点2 ping 控制节点、计算节点1 、计算节点2

(4）存储节点2 时间同步

① 存储节点2

bash 复制代码

[root@storage02 ~]# yum install -y chrony

bash 复制代码

[root@storage02 ~]# vim /etc/chrony.conf
[root@storage02 ~]# systemctl restart chronyd.service && systemctl enable chronyd.service

③测试

bash 复制代码

[root@controller ~]# date

[root@compute01 ~]# date

[root@compute02 ~]# date

[root@storage01 ~]# date

[root@storage02 ~]# date

（5）nfs节点网络

①存储节点2 ping 控制节点、计算节点1 、计算节点2

(6）nfs节点时间同步

① nfs节点

bash 复制代码

[root@nas ~]# yum install -y chrony

bash 复制代码

[root@nas ~]# vim /etc/chrony.conf
[root@nas ~]# systemctl restart chronyd.service && systemctl enable chronyd.service

③测试

bash 复制代码

[root@controller ~]# date

[root@compute01 ~]# date

[root@compute02 ~]# date

[root@storage01 ~]# date

[root@storage02 ~]# date

[root@nas ~]# date

、

(7) 控制节点查看（目前已部署controller、compute01、compute02与storage01）

bash 复制代码

# neutron agent-list

# cinder service-list

2.安装并配置NFS节点

（1）安装软件包

bash 复制代码

# yum install nfs-utils.x86_64 -y

（2）创建共享目录

bash 复制代码

# mkdir /data

# echo "/data 192.168.204.0/24(rw,async,no_root_squash,no_all_squash)" > /etc/exports

# systemctl restart rpcbind nfs

3.安装并配置存储节点storage02

（1）安装软件包

bash 复制代码

# yum install openstack-cinder targetcli python-keystone  -y

# yum install nfs-utils.x86_64 -y

（2）查看共享

bash 复制代码

# showmount -e 192.168.204.229

（3）备份修改cinder配置文件/etc/cinder/cinder.conf

①修改配置文件

bash 复制代码
