创建网络。

1 neutron net-create public –shared –provider:physical_network public –provider:network_type flat
上述指令中的配置信息，依据的是配置文件/etc/neutron/plugins/ml2/ml2_conf.ini中的内容。

[ml2_type_flat]

flat_networks = public

[linux_bridge]

physical_interface_mappings = public:em1

下面创建public的网络，指定网络的起点IP以及结束IP，指定一个IP范围，指定dns以及gateway。

1 [root@node0 opt]# neutron subnet-create public 192.168.1.0/24 –name public –allocation-pool start=192.168.1.140,end=192.168.1.254 –dns-nameserver 219.141.136.10 –gateway 192.168.1.1

web端DNS不能解析的时候，将控制节点的nova.conf文件中的 vnc controller 改为管理IP 然后重启nova服务
systemctl restart openstack-nova-compute
与ceph对接
2个节点一个mon mds 每台主机1个osd

Ceph for Glance and Cinder in OpenStack Liberty
09 MAY 2016 on openstack, ceph, glance, cinder
1.创建新pool

Bash
# ceph osd pool create volumes 4096
# ceph osd pool create images 128
# ceph osd pool create backups 128
# ceph osd pool create vms 4096
2.在控制节点，计算节点安装RPM包

Bash
# yum -y install python-rbd ceph
3.开启cephx情况下，给nova，cinder添加3个用户权限

Bash
# ceph auth get-or-create client.cinder mon ‘allow r’ osd ‘allow class-read object_prefix rbd_children, allow rwx pool=volumes, allow rwx pool=vms, allow rx pool=images’
# ceph auth get-or-create client.glance mon ‘allow r’ osd ‘allow class-read object_prefix rbd_children, allow rwx pool=images’
# ceph auth get-or-create client.cinder-backup mon ‘allow r’ osd ‘allow class-read object_prefix rbd_children, allow rwx pool=backups’
4.控制节点需要以下几个keys
ceph.client.glance.keyring, ceph.client.cinder.keyring, ceph.client.cinder-backup.keyring

Bash
# ceph auth get-or-create client.glance | ssh controller sudo tee /etc/ceph/ceph.client.glance.keyring
# ssh controller sudo chown glance:glance /etc/ceph/ceph.client.glance.keyring
# ceph auth get-or-create client.cinder | ssh controller sudo tee /etc/ceph/ceph.client.cinder.keyring
# ssh controller sudo chown cinder:cinder /etc/ceph/ceph.client.cinder.keyring
# ceph auth get-or-create client.cinder-backup | ssh controller sudo tee /etc/ceph/ceph.client.cinder-backup.keyring
# ssh controller sudo chown cinder:cinder /etc/ceph/ceph.client.cinder-backup.keyring
5.计算节点添加client.cinder.key

Bash
# for i in compute1 compute2;do
ceph auth get-or-create client.cinder | ssh $i sudo tee /etc/ceph/ceph.client.cinder.keyring
ceph auth get-key client.cinder | ssh $i tee client.cinder.key ;
done
6.控制节点添加ceph.client.admin.keyring

Bash
# scp ceph.client.admin.keyring controller:/etc/ceph/
7.编辑ceph.conf
添加以下内容

Bash
[client]
rbd cache = true
rbd cache writethrough until flush = true
rbd default format = 2
[client.glance]
keyring = /etc/ceph/ceph.client.glance.keyring

[client.cinder]
keyring = /etc/ceph/ceph.client.cinder.keyring

[client.cinder-backup]
keyring = /etc/ceph/ceph.client.cinder-backup.keyring
8.复制ceph.conf到所以计算节点

Bash
# for i in compute1 compute2;do
scp /etc/ceph/ceph.conf $i:/etc/ceph/
done
9.添加一个secret key到libvirt

Bash
# uuidgen
397eb3ee-925b-4391-b3d3-36e984a4dc27
cat > secret.xml <<EOF
<secret ephemeral=’no’ private=’no’>
<uuid>397eb3ee-925b-4391-b3d3-36e984a4dc27</uuid>
<usage type=’ceph’>
<name>client.cinder secret</name>
</usage>
</secret>
EOF
导入secret key

Bash
# virsh secret-define –file secret.xml
Secret 397eb3ee-925b-4391-b3d3-36e984a4dc27 created
# virsh secret-set-value –secret 397eb3ee-925b-4391-b3d3-36e984a4dc27 $(cat client.cinder.key)
glance-api.conf修改
Bash
[DEFAULT]
…
default_store = rbd
show_image_direct_url = True

[glance_store]
#default_store = file
#filesystem_store_datadir = /var/lib/glance/images/

##
stores = rbd,file
rbd_store_pool = images
rbd_store_user = glance
rbd_store_ceph_conf = /etc/ceph/ceph.conf
rbd_store_chunk_size = 8
11.cinder.conf修改
添加以下内容：

Bash
[DEFAULT]
…
enabled_backends = lvm,ceph

[ceph]
volume_driver = cinder.volume.drivers.rbd.RBDDriver
volume_backend_name = ceph
rbd_pool = volumes
rbd_ceph_conf = /etc/ceph/ceph.conf
rbd_flatten_volume_from_snapshot = false
rbd_max_clone_depth = 5
rbd_store_chunk_size = 4
rados_connect_timeout = -1
glance_api_version = 2
rbd_user = cinder
rbd_secret_uuid = 397eb3ee-925b-4391-b3d3-36e984a4dc27
12.nova.conf修改
修改libvirt段

Bash
[libvirt]
images_type = rbd
images_rbd_pool = vms
images_rbd_ceph_conf = /etc/ceph/ceph.conf
rbd_user = nova
inject_password = false
inject_key = false
inject_partition = -2
rbd_user = cinder
rbd_secret_uuid = 397eb3ee-925b-4391-b3d3-36e984a4dc27
live_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE, VIR_MIGRATE_PEER2PEER, VIR_MIGRATE_LIVE, VIR_MIGRATE_TUNNELLED
13.重启glance，cinder，nova服务

14.创建新cinder 类型 ceph

Bash
# cinder type-create ceph
# cinder type-key ceph set volume_backend_name=ceph
# cinder service-list
15.创建卷测试

Bash
# cinder create –volume-type ceph –display-name ceph-test 1
# cinder list
# rbd -p volumes ls
16.下载vm 模板系统，导入glance
tips： 需要将模板镜像格式转换为 RAW
