OpenStackTrain版安装glance镜像服务

1.创建数据库并授权

[root&＃64;controller ~]# mysql
MariaDB [(none)]> CREATE DATABASE glance;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO &＃39;glance&＃39;&＃64;&＃39;localhost&＃39; IDENTIFIED BY &＃39;GLANCE_ZHL&＃39;;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO &＃39;glance&＃39;&＃64;&＃39;%&＃39; IDENTIFIED BY &＃39;GLANCE_ZHL&＃39;;


2. 创建glance用户

[root&＃64;controller ~]# openstack user create --domain default --password GLANCE_ZHL glance
&＃43;---------------------&＃43;----------------------------------&＃43;
| Field | Value |
&＃43;---------------------&＃43;----------------------------------&＃43;
| domain_id | default |
| enabled | True |
| id | bcacaaf4eed6422da7951d1cc9982f7c |
| name | glance |
| options | {} |
| password_expires_at | None |
&＃43;---------------------&＃43;----------------------------------&＃43;给glance用户授权
[root&＃64;controller ~]# openstack role add --project service --user glance admin


3. 创建glance服务实体

[root&＃64;controller ~]# openstack service create --name glance --description "OpenStack Image" image
&＃43;-------------&＃43;----------------------------------&＃43;
| Field | Value |
&＃43;-------------&＃43;----------------------------------&＃43;
| description | OpenStack Image |
| enabled | True |
| id | e0c76a13cf314744a120111d64b92c95 |
| name | glance |
| type | image |
&＃43;-------------&＃43;----------------------------------&＃43;


4. 创建镜像服务API访问端点

[root&＃64;controller ~]# openstack endpoint create --region RegionOne image public http://controller:9292
&＃43;--------------&＃43;----------------------------------&＃43;
| Field | Value |
&＃43;--------------&＃43;----------------------------------&＃43;
| enabled | True |
| id | b7f649e9b9274b309a0eebf2c7a7e0ba |
| interface | public |
| region | RegionOne |
| region_id | RegionOne |
| service_id | e0c76a13cf314744a120111d64b92c95 |
| service_name | glance |
| service_type | image |
| url | http://controller:9292 |
&＃43;--------------&＃43;----------------------------------&＃43;
[root&＃64;controller ~]# openstack endpoint create --region RegionOne image internal http://controller:9292
&＃43;--------------&＃43;----------------------------------&＃43;
| Field | Value |
&＃43;--------------&＃43;----------------------------------&＃43;
| enabled | True |
| id | 6cb5d49ecb9a4fac87e73580891d8cf8 |
| interface | internal |
| region | RegionOne |
| region_id | RegionOne |
| service_id | e0c76a13cf314744a120111d64b92c95 |
| service_name | glance |
| service_type | image |
| url | http://controller:9292 |
&＃43;--------------&＃43;----------------------------------&＃43;
[root&＃64;controller ~]# openstack endpoint create --region RegionOne image admin http://controller:9292
&＃43;--------------&＃43;----------------------------------&＃43;
| Field | Value |
&＃43;--------------&＃43;----------------------------------&＃43;
| enabled | True |
| id | a0a0e5309ce54e7e8314506b5e8f3370 |
| interface | admin |
| region | RegionOne |
| region_id | RegionOne |
| service_id | e0c76a13cf314744a120111d64b92c95 |
| service_name | glance |
| service_type | image |
| url | http://controller:9292 |
&＃43;--------------&＃43;----------------------------------&＃43;


5. 安装glance软件包

[root&＃64;controller ~]# yum install openstack-glance


6. 编辑glance的配置文件

cp -a /etc/glance/glance-api.conf{,.bak}
cp -a /etc/glance/glance-registry.conf{,.bak}
grep -Ev &＃39;^$|#&＃39; /etc/glance/glance-api.conf.bak > /etc/glance/glance-api.conf
grep -Ev &＃39;^$|#&＃39; /etc/glance/glance-registry.conf.bak > /etc/glance/glance-registry.confopenstack-config --set /etc/glance/glance-api.conf database connection mysql&＃43;pymysql://glance:GLANCE_ZHL&＃64;controller/glanceopenstack-config --set /etc/glance/glance-api.conf keystone_authtoken www_authenticate_uri http://controller:5000
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_url http://controller:5000
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken memcached_servers controller:11211
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_type password
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken project_domain_name Default
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken user_domain_name Default
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken project_name service
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken username glance
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken password GLANCE_ZHL
openstack-config --set /etc/glance/glance-api.conf paste_deploy flavor keystoneopenstack-config --set /etc/glance/glance-api.conf glance_store stores file,http
openstack-config --set /etc/glance/glance-api.conf glance_store default_store file
openstack-config --set /etc/glance/glance-api.conf glance_store filesystem_store_datadir /var/lib/glance/images/


7. 填充glance数据库

[root&＃64;controller ~]# su -s /bin/sh -c "glance-manage db_sync" glance


8. 启动glance服务并设置开机自启

[root&＃64;controller ~]# systemctl enable openstack-glance-api.service
[root&＃64;controller ~]# systemctl start openstack-glance-api.service


启动好之后&＃xff0c;查看端口情况&＃xff0c;如果有9292端口&＃xff0c;则表示glance启动成功

[root&＃64;controller ~]# lsof -i:9292
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
glance-ap 25529 glance 4u IPv4 77560 0t0 TCP *:armtechdaemon (LISTEN)
glance-ap 25541 glance 4u IPv4 77560 0t0 TCP *:armtechdaemon (LISTEN)


9.下载cirros镜像&＃xff0c;验证glance的安装

[root&＃64;controller ~]# wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
[root&＃64;controller ~]# openstack image create --file /root/cirros-0.4.0-x86_64-disk.img --disk-format qcow2 --container-format bare --public cirros

&＃xff08;官方文档坑点之一&＃xff0c;这里不要使用官方文档里面的glance image-create这样的写法&＃xff0c;新版本的OpenStack已经不支持&＃xff0c;尽量统一使用以openstack开头的命令写法&＃xff09;

[root&＃64;controller ~]# glance image-list
&＃43;--------------------------------------&＃43;--------&＃43;
