安装配置好openstack环境的虚拟机，需要修改ip时，在数据库中同步修改ip的方法
由于配置openstack 环境的时候，创建了很多表，都配置了本机的ip
所以当本机需要修改ip的 时候 就需要同步数据库中所有与环境有关的ip
方法：
1.进入数据库
[root@node Desktop]# mysql -uroot -p
Enter password:

3.进入keystone 数据库
MariaDB [(none)]> use keystone;

5.查看 endpoint 数据表所有内容
MariaDB [keystone]> SELECT * FROM endpoint;

6.用 命令修改 里面所有ip 即可。
例如：
update endpoint set url='http://192.168.0.22:5000/v2.0' where id='2c1bfecbc0354ce8998675ae511139b6';
