参考文章：
  https://docs.openstack.org/train/index.html

注：以下部署过程没有注解。强烈建议查阅官方文档，官方文档有非常详细的注解。

一、环境

Openstack 版本：Train
Linux系统：centos 7.8.1810
节点信息表（控制节点可以既做控制也做计算）：

角色 网卡1（内部网卡） 网卡2（外部网卡）
controller 192.168.100.101 10.0.0.101
compute1 192.168.100.102 10.0.0.102

如果用的VMware模拟，网卡1为仅主机模式，网卡2为NAT模式。

 

二、初始环境准备

各节点都执行
脚本点击下载：openstack-scripts
 

1、统一网卡命名

  centos 7 种，网卡名称一般是根据网卡型号来随机的，这样不方便管理。将其统一修改为以eth0、eth1 这种形式命名。
  在 /etc/default/grub 文件中的 GRUB_CMDLINE_LINUX= 这行后面添加 net.ifnames=0 biosdevname=0 参数，来禁用网卡命名规则。

[root@localhost ~]# cat /etc/default/grub 
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet net.ifnames=0 biosdevname=0"
GRUB_DISABLE_RECOVERY="true"

  生成更新 grub 配置参数，然后重启即可。注意：系统grub也可能走/etc/grub.cfg（Bios）、/etc/grub-efi.cfg（UEFI）、/etc/grub2.cfg（Bios）、/etc/grub2-efi.cfg（UEFI），所以更新的配置参数的时候要找准系统用的grub文件的位置，不然会出现不生效的情况。

[root@localhost ~]# grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-3.10.0-957.el7.x86_64
Found initrd image: /boot/initramfs-3.10.0-957.el7.x86_64.img
Found linux image: /boot/vmlinuz-0-rescue-58e6e0a1ea694fbe8613e28ac3af1aad
Found initrd image: /boot/initramfs-0-rescue-58e6e0a1ea694fbe8613e28ac3af1aad.img
done

[root@localhost ~]# reboot

修改原来网卡配置文件，将 NAME 和 DEVICE 修改为新的网卡名。

[root@localhost ~]# ip -4 a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    inet 192.168.100.101/24 brd 192.168.200.255 scope global eth0
       valid_lft forever preferred_lft forever
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    inet 10.0.0.101/24 brd 10.0.0.255 scope global eth1
       valid_lft forever preferred_lft forever

  

2、全局变量准备

根据自身实际环境填写

[root@localhost openstack-scripts]# vim /etc/openrc.sh

手动修改以下变量（其它批量填写）：
  HOST_IP、HOST_NAME、HOST_IP_NODE、HOST_NAME_NODE、DOMAIN_NAME、RABBIT_USER、INTERFACE_NAME

[root@localhost openstack-scripts]# sed -i 's/^#//g' /etc/openrc.sh
[root@localhost openstack-scripts]# sed -i 's/PASS=/PASS=000000/g'  /etc/openrc.sh

将修改好的全局变量拷贝到计算节点。

[root@controller ~]# scp -rp openstack-scripts 192.168.100.102:/root/
[root@controller ~]# scp -p /etc/openrc.sh  192.168.100.102:/etc/openrc.sh

（4）控制节点也做计算节点（可选）
  修改全局变量文件/etc/openrc.sh，修改HOST_IP_NODE、HOST_NAME_NODE为控制节点的主机名和IP即可。安装完一定记得改回来。

[root@ct openstack-scripts]# vim /etc/openrc.sh
......
#Controller Server Manager IP. example:x.x.x.x
HOST_IP=10.86.68.1

#Controller Server hostname. example:controller
HOST_NAME=controller

#Compute Node Manager IP. example:x.x.x.x
HOST_IP_NODE=10.86.68.1

#Compute Node hostname. example:compute
HOST_NAME_NODE=controller
......
[root@ct openstack-scripts]# ./openstack-install-nova-compute.sh
[root@ct openstack-scripts]# openstack compute service list --service nova-compute

（2）计算节点

openstack-install-cinder-compute.sh

验证：
此时后端存储服务为ceph，但ceph相关服务尚未启用并集成到cinder-volume，所以服务的状态也是down。

[root@ct openstack-scripts]# cinder service-list
+------------------+---------+------+---------+-------+----------------------------+---------+-----------------+---------------+
| Binary           | Host    | Zone | Status  | State | Updated_at                 | Cluster | Disabled Reason | Backend State |

+------------------+---------+------+---------+-------+----------------------------+---------+-----------------+---------------+

  

四、集成ceph

ceph 版本：Nautilus
控制节点和计算节点各有一块STAT盘（sdb）用作ceph集群。
建议再集成前，将之前创建的镜像、块、实例删除。

1、ceph安装

换源（各节点都进行此操作）：

[root@ct ~]# gzip /etc/yum.repos.d/CentOS-Ceph-Nautilus.repo
[root@ct ~]# rpm -vih https://mirrors.aliyun.com/ceph/rpm-nautilus/el7/noarch/ceph-release-1-1.el7.noarch.rpm

ceph集群部署：

source /etc/openrc.sh
yum install -y python-setuptools ceph-deploy ceph
ssh $HOST_NAME_NODE 'yum install -y python-setuptools ceph'
cd /etc/ceph
ceph-deploy new $HOST_NAME $HOST_NAME_NODE
ceph-deploy mon create-initial
ceph-deploy osd create --data /dev/sdb $HOST_NAME
ceph-deploy osd create --data /dev/sdb $HOST_NAME_NODE
ceph-deploy admin $HOST_NAME $HOST_NAME_NODE
chmod +x /etc/ceph/ceph.client.admin.keyring
ssh $HOST_NAME_NODE 'chmod +x /etc/ceph/ceph.client.admin.keyring'
ceph-deploy mgr create $HOST_NAME $HOST_NAME_NODE

ceph osd pool create volumes 64
ceph osd pool create vms 64
ceph osd pool create images 64

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.glance |tee /etc/ceph/ceph.client.glance.keyring
chown glance.glance /etc/ceph/ceph.client.glance.keyring
ceph auth get-or-create client.cinder | tee /etc/ceph/ceph.client.cinder.keyring
chown cinder.cinder /etc/ceph/ceph.client.cinder.keyring

ceph auth get-key client.cinder |ssh c1 tee client.cinder.key
scp -p /etc/ceph/ceph.client.cinder.keyring c1:/etc/ceph

计算节点执行：

cd /root
cat >secret.xml <<EOF
<secret ephemeral='no' private='no'>
   <uuid>ff5883d3-7891-46c2-b1ae-a074283e4905</uuid>
   <usage type='ceph'>
    <name>client.cinder secret</name>
   </usage>
</secret>
EOF
virsh secret-define --file secret.xml
virsh secret-set-value --secret ff5883d3-7891-46c2-b1ae-a074283e4905 --base64 $(cat client.cinder.key) && rm -rf client.cinder.key secret.xml

ceph osd pool application enable vms mon
ceph osd pool application enable images mon
ceph osd pool application enable volumes mon

  

2、对接glance

控制节点执行

cp /etc/glance/glance-api.conf{,.bak1}

openstack-config --set /etc/glance/glance-api.conf glance_store "stores" "glance.store.filesystem.Store, glance.store.http.Store, glance.store.rbd.Store"
openstack-config --set /etc/glance/glance-api.conf glance_store "default_store" "rbd"
openstack-config --set /etc/glance/glance-api.conf glance_store "rbd_store_chunk_size" "8"
openstack-config --set /etc/glance/glance-api.conf glance_store "rbd_store_pool" "images"
openstack-config --set /etc/glance/glance-api.conf glance_store "rbd_store_user" "glance"
openstack-config --set /etc/glance/glance-api.conf glance_store "rbd_store_ceph_conf" "/etc/ceph/ceph.conf"
openstack-config --set /etc/glance/glance-api.conf paste_deploy "flavor" "keystone"

systemctl restart openstack-glance-api.service openstack-glance-registry.service

验证：

[root@ct ~]# openstack image create --file /root/CentOS-7-x86_64-GenericCloud.qcow2 --disk-format qcow2 --container-format bare --public centos7

[root@ct ~]# rbd ls images
9fec3bff-2d2a-426a-9ce7-b1ed9dfdd71a

[root@ct ~]# ceph df
......
POOLS:
    POOL        ID     PGS     STORED      OBJECTS     USED        %USED     MAX AVAIL 
    volumes      6     128         0 B           0         0 B         0        10 GiB 
    images       7     128     819 MiB         109     1.6 GiB         0        10 GiB 
    vms          8     128         0 B           0         0 B         0        10 GiB

  

3、对接cinder

计算节点执行

cp /etc/cinder/cinder.conf{,.bak1}

openstack-config --set /etc/cinder/cinder.conf ceph "default_volume_type" "ceph"
openstack-config --set /etc/cinder/cinder.conf ceph "glance_api_version" "2"
openstack-config --set /etc/cinder/cinder.conf ceph "volume_driver" "cinder.volume.drivers.rbd.RBDDriver"
openstack-config --set /etc/cinder/cinder.conf ceph "volume_backend_name" "ceph"
openstack-config --set /etc/cinder/cinder.conf ceph "rbd_pool" "volumes"
openstack-config --set /etc/cinder/cinder.conf ceph "rbd_ceph_conf" "/etc/ceph/ceph.conf"
openstack-config --set /etc/cinder/cinder.conf ceph "rbd_flatten_volume_from_snapshot" "false"
openstack-config --set /etc/cinder/cinder.conf ceph "rbd_max_clone_depth" "5"
openstack-config --set /etc/cinder/cinder.conf ceph "rbd_store_chunk_size" "4"
openstack-config --set /etc/cinder/cinder.conf ceph "rados_connect_timeout" "-1"
openstack-config --set /etc/cinder/cinder.conf ceph "rbd_user" "cinder"
openstack-config --set /etc/cinder/cinder.conf ceph "rbd_secret_uuid" "ff5883d3-7891-46c2-b1ae-a074283e4905"

systemctl restart openstack-cinder-volume

控制节点执行：

cinder type-create ceph
cinder type-key ceph set volume_backend_name=ceph

验证：

[root@ct ~]# cinder service-list
+------------------+--------------+------+---------+-------+----------------------------+---------+-----------------+---------------+
| Binary           | Host         | Zone | Status  | State | Updated_at                 | Cluster | Disabled Reason | Backend State |

+--------------------------------------+-----------+------+------+-------------+----------+-------------+

  

4、对接nova

计算节点执行（如果控制节点也做计算也要对接下）：

cp /etc/nova/nova.conf{,.bak1}

openstack-config --set /etc/nova/nova.conf libvirt virt_type kvm
openstack-config --set /etc/nova/nova.conf libvirt "images_type" "rbd"
openstack-config --set /etc/nova/nova.conf libvirt "images_rbd_pool" "vms"
openstack-config --set /etc/nova/nova.conf libvirt "images_rbd_ceph_conf" "/etc/ceph/ceph.conf"
openstack-config --set /etc/nova/nova.conf libvirt "rbd_user" "cinder"
openstack-config --set /etc/nova/nova.conf libvirt "rbd_secret_uuid" "ff5883d3-7891-46c2-b1ae-a074283e4905"
openstack-config --set /etc/nova/nova.conf libvirt "live_migration_flag" "VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_LIVE,VIR_MIGRATE_PERSIST_DEST,VIR_MIGRATE_TUNNELLED"

yum install -y libvirt
systemctl restart libvirtd
systemctl enable libvirtd
systemctl restart openstack-nova-compute

验证，自行创建云主机验证。
  

五、扩展组件

1、heat

控制节点执行

openstack-install-heat.sh

验证：

[root@controller openstack-scripts]# openstack orchestration service list
+------------+-------------+--------------------------------------+------------+--------+----------------------------+--------+
