openstack controller ha测试环境搭建记录（十）——配置neutron（控制节点）

创建neutron用户：
mysql -u root -p

CREATE DATABASE neutron;
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY '123456';
exit

创建用户、服务、endpoint：
keystone user-create --name neutron --pass 123456
keystone user-role-add --user neutron --tenant service --role admin
keystone service-create --name neutron --type network --description "OpenStack Networking"
keystone endpoint-create \
  --service-id $(keystone service-list | awk '/ network / {print $2}') \
  --publicurl http://myvip:9696 \
  --adminurl http://myvip:9696 \
  --internalurl http://myvip:9696

在每个控制节点安装：
yum install -y openstack-neutron openstack-neutron-ml2 python-neutronclient which

在每个控制节点修改配置文件：

初始化数据库：
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade juno" neutron

启动相关服务：
systemctl restart openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service
systemctl enable neutron-server.service
systemctl start neutron-server.service
