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:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 2
Server version: 5.5.40-MariaDB-wsrep MariaDB Server, wsrep_25.11.r4026

Copyright (c) 2000, 2014, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]>

2.显示所有数据    show database；

MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| glance             |
| keystone           |
| mysql              |
| nova               |
| performance_schema |
| test               |
+--------------------+
7 rows in set (0.12 sec)

MariaDB [(none)]>

3.进入keystone 数据库

MariaDB [(none)]> use keystone;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
MariaDB [keystone]>

4.查看 所有数据表

MariaDB [keystone]> show tables;
+-----------------------+
| Tables_in_keystone    |
+-----------------------+
| assignment            |
| credential            |
| domain                |
| endpoint              |
| group                 |
| migrate_version       |
| policy                |
| project               |
| region                |
| role                  |
| service               |
| token                 |
| trust                 |
| trust_role            |
| user                  |
| user_group_membership |
+-----------------------+
16 rows in set (0.00 sec)

MariaDB [keystone]>

5.查看 endpoint 数据表所有内容

MariaDB [keystone]> SELECT * FROM endpoint;
+----------------------------------+----------------------------------+-----------+-----------+----------------------------------+-------------------------------------------+-------+---------+
| id                               | legacy_endpoint_id               | interface | region    | service_id                       | url                                       | extra | enabled |
+----------------------------------+----------------------------------+-----------+-----------+----------------------------------+-------------------------------------------+-------+---------+

MariaDB [keystone]>
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';
