• 确保glance endpoint正常服务

安装glance 软件

yum install opentack-glance

报错 Error: Package: device-mapper-multipath-0.4.9-133.el7.x86_64 (centos-base)

rpm -e --nodeps kpartx-0.4.9-135.el7_9.x86_64
yum install opentack-glance -y

• 确保服务正确安装

修改glance-api.conf，glance-registry.conf 同步修改配置

[database]  
  
connection = mysql+pymysql://glance:D3LvC@F01xmR@10.8.4.38/glance


[keystone_authtoken]  
  
auth_url = http://10.8.4.38:5000/v3  
memcached_servers = 10.8.4.38:11211  
auth_type = password  
project_domain_name = default  
user_domain_name = default  
project_name = service  
username = glance  
password = D3LvC@F01xmR


[paste_deploy]  
  
flavor = keystone

初始化数据库

su -s /bin/sh -c "glance-manage db_sync" glance
mysql -uglance -pD3LvC@F01xmR -e "use glance; show tables;"

• 确保服务能用，数据库以及表能够正常使用

启动服务

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

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

报错

• 重新执行上述命令

可以正常使用，确保9292端口开启。
