一、查看信息

站在用戶的角度思考問題，與客戶深入溝通，找到大安市網(wǎng)站設(shè)計與大安市網(wǎng)站推廣的解決方案，憑借多年的經(jīng)驗，讓設(shè)計與互聯(lián)網(wǎng)技術(shù)結(jié)合，創(chuàng)造個性化、用戶體驗好的作品，建站類型包括：成都網(wǎng)站設(shè)計、網(wǎng)站制作、企業(yè)官網(wǎng)、英文網(wǎng)站、手機端網(wǎng)站、網(wǎng)站推廣、域名申請、虛擬空間、企業(yè)郵箱。業(yè)務(wù)覆蓋大安市地區(qū)。

1)鑒權(quán)

[root@rong ~]# cat keystonerc_admin 
unset OS_SERVICE_TOKEN
   export OS_USERNAME=admin
   export OS_PASSWORD='8d07f364025d414e'
   export OS_REGION_NAME=RegionOne
   export OS_AUTH_URL=http://192.168.222.128:5000/v3
   export PS1='[\u@\h \W(keystone_admin)]\$ '

export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_IDENTITY_API_VERSION=3
   [root@rong ~]# source keystonerc_admin 
[root@rong ~(keystone_admin)]#

2)查看規(guī)格，下列規(guī)格是默認有的

[root@rong ~(keystone_admin)]# openstack flavor list
+----+-----------+-------+------+-----------+-------+-----------+
| ID | Name    |  RAM | Disk | Ephemeral | VCPUs | Is Public |
+----+-----------+-------+------+-----------+-------+-----------+
| 1  | m1.tiny  |  512 |   1 |     0 |   1 | True    |
| 2  | m1.small  |  2048 |  20 |     0 |   1 | True    |
| 3  | m1.medium |  4096 |  40 |     0 |   2 | True    |
| 4  | m1.large  |  8192 |  80 |     0 |   4 | True    |
| 5  | m1.xlarge | 16384 |  160 |     0 |   8 | True    |
+----+-----------+-------+------+-----------+-------+-----------+
[root@rong ~(keystone_admin)]#

3)查看鏡像

[root@rong ~(keystone_admin)]# openstack image list
+--------------------------------------+-----------+--------+
| ID                  | Name    | Status |
+--------------------------------------+-----------+--------+
| fd04d446-f1cb-4aa8-9f72-f414a71faefc | cirros   | active |
| 587655c8-87ea-4c3f-bdba-41a763667d57 | cirrosnew | active |
+--------------------------------------+-----------+--------+

由于默認的鏡像大小不對，創(chuàng)建虛擬機會報錯，這里上傳了新的鏡像，具體操作請看“故障處理”。
4)查看網(wǎng)絡(luò)

[root@rong ~(keystone_admin)]# openstack network list
+--------------------------------------+---------+--------------------------------------+
| ID                  | Name   | Subnets                |
+--------------------------------------+---------+--------------------------------------+
| 573ad869-aa73-4c8c-a57c-033590c4f8f1 | private | 1f5a428e-e7f4-430b-9bdd-adedf2692d5b |
| 6aa84627-9631-4c2c-8549-2fc7880d8d18 | public  | ae58274e-eaf3-467f-adc1-dec7b39a3084 |
+--------------------------------------+---------+--------------------------------------+

二、創(chuàng)建虛擬機
1)通過openstack界面創(chuàng)建

2)查看虛擬機

3)通過VNC進入虛擬機操作系統(tǒng)

三、故障排除
1)OpenStack報錯:Host is not mapped to any cell
通過命令創(chuàng)建虛擬機報錯：Host is not mapped to any cell，通過執(zhí)行nova-manage cell_v2 discover_hosts --verbose后，可以創(chuàng)建虛擬機。
參考：https://blog.51cto.com/3241766/2328408
2)openstack vnc報錯：failed to connect to server (code: 1006)
在vmware中使用火狐登陸openstack，通過VNC登陸，報錯failed to connect to server (code: 1006)，通過在/etc/hosts中添加主機名和IP地址解析后，可以打開VNC。
參考：https://blog.51cto.com/01000/1926756
3)默認的cirror鏡像有問題導(dǎo)致創(chuàng)建虛擬機報錯
故障排除思路：剛開始通過命令創(chuàng)建虛擬機可以運行，但通過界面創(chuàng)建虛擬機報did not finish being created even after we waited 22 seconds的錯誤，查看磁盤也是錯誤的，還以為cinder沒配置好，但單獨創(chuàng)建磁盤又是正常的，再看了cinder的日志，發(fā)現(xiàn)lvm': Image is not in qcow2 format，查看默認的鏡像，發(fā)現(xiàn)鏡像只有4k，而cirros正常應(yīng)該是13M左右，于是上傳新的cirros，再次創(chuàng)建虛擬機，問題解決。

通過winscp上傳新鏡像cirros-0.4.0-x86_64-disk.img：

通過命令上傳：

openstack image create "cirrosnew" \
--file cirros-0.3.5-x86_64-disk.img \
--disk-format qcow2 --container-format bare \
--public
