11 Openstack-Ussuri-Cinder控制节点集群部署-centos8

其他 2020-09-09 05:17:02 阅读次数: 0

cinder具体功能如下：
1 提供 REST API 使用户能够查询和管理 volume、volume snapshot 以及 volume type
2 提供 scheduler 调度 volume 创建请求，合理优化存储资源的分配
3 通过 driver 架构支持多种 back-end（后端）存储方式，包括 LVM，NFS，Ceph 和其他诸如 EMC、IBM 等商业存储产品和方案

11.1 配置cinder数据库

#使用root登陆数据库：

mysql -u root -p

#创建cinder数据库:

CREATE DATABASE cinder;

#授予对cinder数据库的访问权限，刷新退出数据库:

GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
  IDENTIFIED BY 'cinder.123';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \
  IDENTIFIED BY 'cinder.123';
flush privileges;
exit

11.2 加载管理凭证

source adminrc.sh

11.3 创建cinder相关服务凭证

#创建cinder服务用户，并设置密码为cinder.123

openstack user create --domain default --password-prompt cinder

#输出

User Password:
Repeat User Password:

11.5 部署与配置cinder - ALL Controller

#安装包

yum install openstack-cinder -y

#备份cinder配置

cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.bak
egrep -v "^$|^#" /etc/cinder/cinder.conf.bak >/etc/cinder/cinder.conf

#配置cinder配置文件，在对应项底下增加以下字段
#vim /etc/cinder/cinder.conf


[DEFAULT]
# ...
my_ip = 172.16.1.160
transport_url = rabbit://rabbitmq:rabbitmq.123@controller160:5672,rabbitmq:rabbitmq.123@controller161:5672,rabbitmq:rabbitmq.123@controller162:5672
auth_strategy = keystone
osapi_volume_listen = 172.16.1.160
osapi_volume_listen_port = 8776
[database]
# ...
connection = mysql+pymysql://cinder:cinder.123@controller168/cinder

[keystone_authtoken]
# ...
www_authenticate_uri = http://controller168:5000
auth_url = http://controller168:5000
memcached_servers = controller160:11211,controller161:11211,controller162:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = cinder
password = cinder.123

[oslo_concurrency]
# ...
lock_path = /var/lib/cinder/tmp

#添加nova配置，使用cinder服务
#vim /etc/nova/nova.conf

[cinder]
os_region_name = RegionOne

#填充cinder数据库，无输出

su -s /bin/sh -c "cinder-manage db sync" cinder

#验证cinder数据库是否正常写入：

mysql -h controller168 -ucinder -pcinder.123 -e "use cinder;show tables;"

#重启nova服务

systemctl restart openstack-nova-api.service

#重启cinder服务，并配置开机启动:

systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl restart openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl status openstack-cinder-api.service openstack-cinder-scheduler.service

11.6 cinder服务验证

#加载管理凭证

source adminrc.sh

#查看服务列表

openstack volume service list

#输出

[root@controller160 ~]# openstack volume service list
+------------------+---------------+------+---------+-------+----------------------------+

11.7 设置pcs资源

#在任意控制节点操作；
#添加资源cinder-api与cinder-scheduler

pcs resource create openstack-cinder-api systemd:openstack-cinder-api clone interleave=true
pcs resource create openstack-cinder-scheduler systemd:openstack-cinder-scheduler clone interleave=true

#cinder-api与cinder-scheduler以active/active模式运行；
#openstack-nova-volume以active/passive模式运行

#查看资源
