Centos 8部署openstack u 版 （二）
五： Networking service Installation Guide
5.1 controller 上配置：
5.1.1 $ mysql -u root -p
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \
IDENTIFIED BY 'NEUTRON_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \
IDENTIFIED BY 'NEUTRON_DBPASS';
5.1.2 create the service credentials
$ openstack user create --domain default --password-prompt neutron
$ openstack role add --project service --user neutron admin
$ openstack service create --name neutron --description "OpenStack Networking" network
$ openstack endpoint create --region RegionOne network public http://controller:9696
$openstack endpoint create --region RegionOne network internal http://controller:9696
$ openstack endpoint create --region RegionOne network admin http://controller:9696
//安装包，并配置：
# yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables
# yum install python3-openstackclient

2 # vim local_settings
#很多地方不用改，比如在controller上装dashboard 127.0.0.1 就不用改
#允许所以HOSTS登录

#时区我就不改了
# TIME_ZONE = "TIME_ZONE"
3 vim /etc/httpd/conf.d/openstack-dashboard.conf
添加
WSGIApplicationGroup %{GLOBAL}
4 cd /usr/share/openstack-dashboard
# python3 manage.py make_web_conf --apache > /etc/httpd/conf.d/openstack-dashboard.conf
5 # systemctl restart httpd.service memcached.service
