OpenStack 三 glance组件部署

前言

• 接着OpenStack Keystore组件实验，继续配置，为openstack安装glance组件，以下操作全部在控制节点ct（192.168.139.12）上操作

一.创建数据库实例和数据库用户

mysql -u root -p         #登录mysql
CREATE DATABASE glance;  #输入密码

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'GLANCE_DBPASS';
#授权glance用户在本地所有库所有表拥有所有权限，密码是GLANCE_DBPASS

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'GLANCE_DBPASS';
#授权glance用户在所有主机所有库所有表拥有所有权限，密码是GLANCE_DBPASS

flush privileges;        #刷新权限
exit                     #退出数据库

二.创建用户、修改配置文件

openstack user create --domain default --password GLANCE_PASS glance
openstack role add --project service --user glance admin
openstack service create --name glance --description "OpenStack Image" image
openstack endpoint create --region RegionOne image public http://ct:9292
openstack endpoint create --region RegionOne image internal http://ct:9292
openstack endpoint create --region RegionOne image admin http://ct:9292

openstack user create --domain default --password GLANCE_PASS glance          #创建用户glance，default域密码GLANCE_PASS

openstack role add --project service --user glance admin                      #将glance用户添加到service项目中，并且针对此项目拥有admin权限

openstack service create --name glance --description "OpenStack Image" image  #创建一个service服务，service名称为glance，类型为image；创建完成后通过openstack service list查看

openstack endpoint create --region RegionOne image public http://ct:9292      #创建镜像api端点public服务（openstack三种api端点代表admin，interbal，public三种服务）

openstack endpoint create --region RegionOne image internal http://ct:9292    #创建镜像api端点internal服务

openstack endpoint create --region RegionOne image admin http://ct:9292       #创建镜像api端点admin服务

三.修改配置文件

1.安装 openstack-glance 软件包
yum -y install openstack-glance            #安装 openstack-glance 软件包

2.修改glance配置文件
cd /etc/glance/                            #进入/etc/glance/目录
ls                                         #查看
glance-api.conf     glance-registry.conf   #两个配置文件

3.添加glance-api.conf配置
cp -a /etc/glance/glance-api.conf{,.bak}   #不改变原属性备份
grep -Ev '^$|#' /etc/glance/glance-api.conf.bak > /etc/glance/glance-api.conf  #去除备份文件中空格和#号，注入的配置文件中

4.传参，添加glance-api.conf配置
openstack-config --set /etc/glance/glance-registry.conf database connection  mysql+pymysql://glance:GLANCE_DBPASS@t/glance
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken www_authenticate_uri   http://ct:5000
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken auth_url  http://ct:5000
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken memcached_servers  ct:11211
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken auth_type  password
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken project_domain_name  Default
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken user_domain_name  Default
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken project_name  service
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken username  glance
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken password  GLANCE_PASS
openstack-config --set /etc/glance/glance-registry.conf paste_deploy flavor  keystone

cat glance-api.conf

5.修改glance-registry.conf 配置文件
cp -a /etc/glance/glance-registry.conf{,.bak}
grep -Ev '^$|#' /etc/glance/glance-registry.conf.bak > /etc/glance/glance-registry.conf

##传参##
openstack-config --set /etc/glance/glance-registry.conf database connection  mysql+pymysql://glance:GLANCE_DBPASS@t/glance
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken www_authenticate_uri   http://ct:5000
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken auth_url  http://ct:5000
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken memcached_servers  ct:11211
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken auth_type  password
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken project_domain_name  Default
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken user_domain_name  Default
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken project_name  service
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken username  glance
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken password  GLANCE_PASS
openstack-config --set /etc/glance/glance-registry.conf paste_deploy flavor  keystone

cat glance-registry.conf

6.初始化glance数据库生成相关表连接
su -s /bin/sh -c "glance-manage db_sync" glance

systemctl enable openstack-glance-api.service     #设置开机自启动服务
systemctl start openstack-glance-api.service      #开启服务

netstat -natp | grep 9292 （ 也可以lsof -i:9292，lsof需要安装）                       #查看端口
yum -y install lsof                               #安装lsof
lsof -i:9292  
chown -hR glance:glance /var/lib/glance/          #赋予openstack-glance-api.service服务对存储设备的可写权限（-h：值对符号连接/软链接的文件修改）

7.镜像导入
cd /opt
ls
openstack image create --file cirros-0.3.5-x86_64-disk.img --disk-format qcow2 --container-format bare --public cirros

8.查看镜像的两种方式
openstack image list
glance image-list
