OpenStack存储节点cinder服务安装部署

块存储节点OpenStack基础环境部署

修改网络接口

auto lo
iface lo inet loopback
auto enp6s7
iface enp6s7 inet static
address 10.0.0.41
netmask 255.255.255.0
gateway 10.0.0.1

修改hosts文件

# controller
10.0.0.11       controller

# compute1
10.0.0.31       compute1

#block1
10.0.0.41       block1

修改hostname文件

sudo vim /etc/hostname

将主机名修改为block1,与hosts文件中的值对应

验证连接

ping -c 4 compute1
PING compute1 (10.0.0.31) 56(84) bytes of data.
64 bytes from compute1 (10.0.0.31): icmp_seq=1 ttl=64 time=0.263 ms
64 bytes from compute1 (10.0.0.31): icmp_seq=2 ttl=64 time=0.202 ms
64 bytes from compute1 (10.0.0.31): icmp_seq=3 ttl=64 time=0.203 ms
64 bytes from compute1 (10.0.0.31): icmp_seq=4 ttl=64 time=0.202 ms

--- compute1 ping statistics ---
4 packets transmitted, 4 received, 0% packet loss, time 3000ms
rtt min/avg/max/mdev = 0.202/0.217/0.263/0.030 ms

安装NTP校时

下载ntp软件包

sudo apt-get install ntp

修改/etc/ntp.conf文件。

sudo vi /etc/ntp.conf

注释或者删除红色框内的内容。

在红框下方添加server controller,表示从controller节点去同步时间。

重启ntp服务

sudo service ntp restart

查看ntp同步状态

ntpq -p

修改时区配置

sudo tzselect

选择区域:Asia(亚洲),输入4
选择国家:china (中国),输入9
选择时区:BeiJing Time (北京时间),输入1
确认验证:yes,输入1
复制配置文件到/etc/localtime,并改名为localtime

sudo cp /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime

查看确认

date

下载OpenStack安装包

启用openstack库

sudo apt install software-properties-common
sudo add-apt-repository cloud-archive:pike

更新节点上所有的软件包

sudo apt update && sudo  apt dist-upgrade

安装openstack客户端

sudo apt install python-openstackclient

在块存储节点上部署cinder服务

安装lvm逻辑卷管理工具

sudo apt install lvm2

创建物理卷

sudo  pvcreate /dev/sdb

sdb为硬盘分区

创建卷组

sudo vgcreate cinder-volumes /dev/sdb

安装cinder-volume

sudo apt install cinder-volume

修改/etc/cinder/cinder.conf文件

设置数据库连接

[database]
# ...
connection = mysql+pymysql://cinder:CINDER_DBPASS@controller/cinder

设置rabbitmq连接

[DEFAULT]
# ...
transport_url = rabbit://openstack:RABBIT_PASS@controller

将RABBIT_PASS替换为你之前部署rabbitmq时设置的密码

设置keystone访问

[DEFAULT]
# ...
auth_strategy = keystone

[keystone_authtoken]
# ...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = CINDER_PASS

替换CINDER_PASS为你自己的密码

设置ip

[DEFAULT]
# ...
my_ip = MANAGEMENT_INTERFACE_IP_ADDRESS

替换MANAGEMENT_INTERFACE_IP_ADDRESS为管理网络块存储节点的IP,这里为10.0.0.41

设置lvm参数

[lvm]
# ...
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = tgtadm
[DEFAULT]
# ...
enabled_backends = lvm

设置镜像服务调用api

[DEFAULT]
# ...
glance_api_servers = http://controller:9292

设置lock_path

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

完成安装

sudo service tgt restart
sudo service cinder-volume restart
