CREATE DATABASE nova;

CREATE DATABASE nova_cell0;

CREATE DATABASE placement;

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'D3LvC@F01xmR';

  • 确保数据库创建成功

  • 确保nova用户能够正常使用

创建nova用户

openstack user create --domain default --password-prompt nova

# D3LvC@F01xmR
  • 确保用户创建成功

image.png

将admin添加到nova用户,并创建服务实体

openstack role add --project service --user nova admin

openstack service create --name nova --description "OpenStack Compute" compute
  • 确保服务和实体创建成功

image.png

创建 nova endpoint

openstack endpoint create --region RegionOne compute public http://10.8.4.38:8774/v2.1

openstack endpoint create --region RegionOne compute internal http://10.8.4.38:8774/v2.1

openstack endpoint create --region RegionOne compute admin http://10.8.4.38:8774/v2.1

image.png

创建placement用户和密码

openstack user create --domain default --password-prompt placement

# D3LvC@F01xmR

image.png

使用admin角色将Placement用户添加到服务项目

openstack role add --project service --user placement admin


openstack service create --name placement --description "Placement API" placement

image.png

创建placement的endpoint


openstack endpoint create --region RegionOne placement public http://10.8.4.38:8778

openstack endpoint create --region RegionOne placement internal http://10.8.4.38:8778

openstack endpoint create --region RegionOne placement admin http://10.8.4.38:8778
  • 确保endpoint创建成功 image.png

安装nova

yum install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler openstack-nova-placement-api -y
  • 确保nova服务正确安装

修改nova http配置

# vi /etc/httpd/conf.d/00-nova-placement-api.conf

在末尾添加

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

重启httpd服务

systemctl restart httpd

初始化数据库

su -s /bin/sh -c "nova-manage api_db sync" nova
su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova

# 73251374-1c8e-4dab-9b41-46f8bc55f3fd

su -s /bin/sh -c "nova-manage db sync" nova
su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova

验证数据库

mysql -unova -pD3LvC@F01xmR -e "use nova ; show tables;"
mysql -unova -pD3LvC@F01xmR -e "use nova_api ; show tables;"
mysql -unova -pD3LvC@F01xmR -e "use nova_cell0 ; show tables;"
mysql -uplacement -pD3LvC@F01xmR -e "use placement ; show tables;"
  • 确保正确访问数据库 image.png
systemctl enable openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service 

systemctl start openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service  openstack-nova-novncproxy.service
  • 确保服务正常运行

解决方案

# vim /etc/my.cnf.d/mariadb-server.cnf

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
# 添加最大连接数
max_connection = 4096
wait_timeout = 5
# ！！！！！ 未生效

方案2

# vi /usr/lib/systemd/system/mariadb.service


systemctl daemon-reload
systemctl restart  mariadb.service

执行后生效

MariaDB [(none)]> show variables like 'max_connections';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 4096  |
+-----------------+-------+

Nova 计算节点的安装 计算节点！！！！！

  • 分别在39 40 节点输入
yum install -y openstack-nova-compute

报错

启动 compute 节点nova服务

systemctl enable libvirtd.service openstack-nova-compute.service

systemctl start libvirtd.service openstack-nova-compute.service
  • 确保不报错

在控制节点！！将计算节点加入集群，并运行命令发现主机

openstack compute service list --service nova-compute

su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
