8.CentOS7下Openstack-Train版本安装--网络服务neutron（控制节点）
1.创建neutron数据库
[ ~]# mysql -u root -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 918 Server version: 10.3.10-MariaDB MariaDB Server Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement. MariaDB [(none)]> CREATE DATABASE neutron; Query OK, 1 row affected (0.000 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘localhost‘ IDENTIFIED BY ‘neutron‘; Query OK, 0 rows affected (0.002 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘%‘ IDENTIFIED BY ‘neutron‘; Query OK, 0 rows affected (0.001 sec) MariaDB [(none)]> flush privileges; Query OK, 0 rows affected (0.002 sec) MariaDB [(none)]> exit Bye
2.创建neutron用户

7.建立ml2的软链接
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
8.填充neutron数据库
su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron
9.重启nova-api服务
systemctl restart openstack-nova-api.service
10.启动neutron服务并设置开机启动
systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service systemctl start neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
11.查看neutron服务状态
systemctl status neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service netstat -tnlup
