OpenStack Train Offline deployment | 5 Controller node -Placement service component

Official reference link: OpenStack Official Installation Guide: Service Component OpenStack Official Installation Guide: Placement -install

Create placement related databases, credentials, and API endpoints

1. Create a Placement database and authorize it

Log in to the mysql database as user root. The password is root that was set during the initialization of mysql data during the preparation of the controller node environment.

mysql -u root -proot
Copy the code

Create the Placement database and authorize it

CREATE DATABASE placement;
GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY 'placement';
GRANT ALL PRIVILEGES ON placement.* TO 'placement'@The '%' IDENTIFIED BY 'placement';

flush privileges;
show databases;
select user,host from mysql.user;

exit

Copy the code

2. Create service credentials

Again, create and register a service certificate for the project

cd 
source admin-openrc.sh
#Domain user
openstack user create --domain default --password=placement placement
#project
openstack role add --project service --user placement admin
#entity
openstack service create --name placement --description "Placement API" placement

# 
Copy the code

3. Create placement project endpoint (API port)

openstack endpoint create --region RegionOne placement public http://controller:8778
openstack endpoint create --region RegionOne placement internal http://controller:8778
openstack endpoint create --region RegionOne placement admin http://controller:8778
openstack endpoint list
Copy the code

Ii. Placement related software installation and configuration

1. Install placement software

yum install openstack-placement-api -y
Copy the code

2. Modify the configuration file

(1) the/etc/placement/placement. Conf, in turn, execute the following command, writes it to the script, execute the script

touch placement.conf.sh
vim placement.conf.sh
bash placement.conf.sh
Copy the code

Placement. Conf. sh File contents

#! /bin/bash #placement.conf.sh openstack-config --set /etc/placement/placement.conf api auth_strategy keystone openstack-config --set /etc/placement/placement.conf keystone_authtoken auth_url http://controller:5000/v3 openstack-config --set /etc/placement/placement.conf keystone_authtoken memcached_servers controller:11211 openstack-config --set /etc/placement/placement.conf keystone_authtoken auth_type password openstack-config --set /etc/placement/placement.conf keystone_authtoken project_domain_name default openstack-config --set /etc/placement/placement.conf keystone_authtoken user_domain_name default openstack-config --set /etc/placement/placement.conf keystone_authtoken project_name service openstack-config --set /etc/placement/placement.conf keystone_authtoken username placement openstack-config --set /etc/placement/placement.conf  keystone_authtoken password placement openstack-config --set /etc/placement/placement.conf placement_database connection mysql+pymysql://placement:placement@controller/placement echo "Result of Configuration" grep '^[a-z]' /etc/placement/placement.confCopy the code
bash placement.conf.sh  
Copy the code

/etc/httpd/conf.d/00-placement-api.conf Train /etc/httpd/conf.d/00-placement-api.conf /etc/httpd/conf.d/00-placement-api.conf /etc/httpd/conf.d/00-placement- API.

vim /etc/httpd/conf.d/00-placement-api.conf
Copy the code

Add the following at the end

<Directory /usr/bin>
   <IfVersion >= 2.4>
      Require all granted
   </IfVersion>
   <IfVersion < 2.4>
      Order allow,deny
      Allow from all
   </IfVersion>
   
</Directory>
Copy the code

3. Synchronize placement database

(1) Synchronization and initialization

Su -s /bin/sh -c "placement-manage db sync" placement # If any warning is displayed, run the command againCopy the code

(2) After synchronization is completed, connection tests are performed to ensure that all required tables have been established, otherwise it may not be possible to proceed later

mysql -uplacement -pplacement -e "use placement; show tables;"Copy the code

4. Configure more information

[optional]

cd 
source admin-openrc.sh
placement-status upgrade check
pip install osc-placement
openstack --os-placement-api-version 1.2 resource class list --sort-column name
Copy the code

5. Restart the Apache service (HTTPD). If the restart fails, pay attention to firewall configurations

systemctl restart httpd
systemctl status httpd 
Copy the code

Iii. Placement service has been installed.
