OpenStack Mirror Service Glance [3]

Openstack

Time: November 28, 2016

Introduction to OpenStack mirroring service Glance

To create a virtual machine, we need to have the support of glance, because glance provides mirroring service.

Glance has two more important services

Glance-api accepts requests for building, deleting and reading cloud system images.

Image Registration Service for Glance-Registry Cloud system

We need to configure glance-api configuration file and glance-registry configuration file

Glance does not need to configure message queuing, but glance needs to configure keystone (Certification Authority)

Tip: uploading images are stored under / var/lib/glance/p_w_picpaths by default.

Install glance

Create the database and wear the glance user on keystone. We have created it.

Install the package

[root@linux-node1 ~] # yum install openstack-glance-y

Modify database address

[root@linux-node1 ~] # vim / etc/glance/glance-api.conf [database]... Connection = mysql+pymysql://glance:glance@192.168.56.11/glance... [root@linux-node1 ~] # vim / etc/glance/glance-registry.conf [database]... Connection = mysql+pymysql://glance:glance@192.168.56.11/glance... # Open the comment and write the mysql address. Note that it is under the database default.

After the modification, we need to synchronize the database

[root@linux-node1] # su-s / bin/sh-c "glance-manage db_sync" glance# creates the table structure for us. It doesn't matter if openstack has a warning, as long as it's not error.

After synchronizing the database, we check.

We need to make sure that the database can be synchronized

Set up keystone

Set up in [keystone_authtoken]

[root@linux-node1] # vim / etc/glance/glance-api.conf... [keystone_authtoken] auth_uri = http://192.168.56.11:5000auth_url = http://192.168.56.11:35357memcached_servers = 192.168.56.11:11211auth_type = password # Verification type is password project_domain_name = default # default domain user_domain_name = default # user default domain project_name = service # Project name username = glance # user password = glance # password

Tip: it must be copied under [keystone_authtoken] module, otherwise it will not take effect.

You also need to set up the [paste_deploy] module

[paste_deploy] flavor = keystone# remove the comment and change it to keystone

Set registry, which is the same as api

[root@linux-node1] # vim / etc/glance/glance-registry.conf... [keystone_authtoken] auth_uri = http://192.168.56.11:5000auth_url = http://192.168.56.11:35357memcached_servers = 192.168.56.11:11211auth_type = password project_domain_name = default user_domain_name = default project_name = service username = glance password = glance... [paste_deploy] flavor = keystone

Configure the mirror path

Configure local file system storage and mirror file locations in glance-api

[root@linux-node1] # vim / etc/glance/glance-api.conf... [glance_store] stores = file,httpdefault_store = filefilesystem_store_datadir = / var/lib/glance/p_w_picpaths# all the above configurations can be done by opening the comments

Check

Glance-api configuration file configuration summary:

[root@linux-node1 ~] # grep'^ [Amurz]'/ etc/glance/glance-api.conf connection = mysql+pymysql://glance:glance@192.168.56.11/glancestores = file Httpdefault_store = filefilesystem_store_datadir = / var/lib/glance/p_w_picpathsauth_uri = http://192.168.56.11:5000auth_url = http://192.168.56.11:35357memcached_servers = 192.168.56.11:11211auth_type = password project_domain_name = default user_domain_name = defaultproject_name = service username = glancepassword = glanceflavor = keystone

The registry configuration is as follows

[root@linux-node1 ~] # grep'^ [a Murz]'/ etc/glance/glance-registry.conf connection = mysql+pymysql://glance:glance@192.168.56.11/glanceauth_uri = http://192.168.56.11:5000auth_url = http://192.168.56.11:35357memcached_servers = 192.168.56.11:11211auth_type = password project_domain_name = defaultuser_domain_name = default project_name = service username = glance Password = glance flavor = keystone hint: the configuration of registry and api is the same as mine. Now we can start.

Set to enable startup and enable the service

[root@linux-node1 ~] # systemctl enable openstack-glance-api.service [root@linux-node1 ~] # systemctl enable openstack-glance-registry.service [root@linux-node1 ~] # systemctl start openstack-glance-api.service [root@linux-node1 ~] # systemctl start openstack-glance-registry.service

Tip: 9292 is the port of glance-api and 9191 is the port of glance-registry

Set up service registration on keystone

1. Create a service

two。 Create an API endpoint for the mirrored service

test

We can use openstack list or glance list to view it.

[root@linux-node1 ~] # openstack p_w_picpath list [root@linux-node1 ~] # glance pendant pictureListListListMutel Muffin + | ID | Name | +-+ +-+-- +-+

Tip: if there is no empty space here, then you need to read the log at this time.

Finally, we can upload an image for testing.

[root@linux-node1 ~] # wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img

Let's download the image above and test it.

# hint: if there are no environment variables, you still need to source

Check whether the upload is successful
