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

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

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

③测试

[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

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

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

③测试

[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）

# neutron agent-list

# cinder service-list

2.安装并配置NFS节点

（1）安装软件包

# yum install nfs-utils.x86_64 -y

（2）创建共享目录

# 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

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

# yum install nfs-utils.x86_64 -y

（2）查看共享

# 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

[DEFAULT]
rpc_backend = rabbit
auth_strategy = keystone
my_ip = 192.168.204.222
glance_api_servers = http://controller:9292
enabled_backends = nfs
[BACKEND]

[CISCO_FABRIC_EXAMPLE]
[COORDINATION]
[FC-ZONE-MANAGER]
[KEYMGR]
[cors]
[cors.subdomain]
[database]
connection = mysql+pymysql://cinder:CINDER_DBPASS@controller/cinder
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password

lock_path = /var/lib/cinder/tmp
[oslo_messaging_amqp]

[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS
[oslo_middleware]

[ssl]
[nfs]
volume_driver = cinder.volume.drivers.nfs.NfsDriver
nfs_share_config = /etc/cinder/nfs_shares
volume_backend_name = nfs

② 添加共享文件配置并重启服务
