前言

有两台openstack环境，都是regionOne ，现在要做的是
将两个region整合在一个dashboard中，其中一个为reginOne，一个为regionTwo

现在已经装好两个环境
10.10.0.73 server73.e3cloud
10.10.0.101 server101.e3cloud.com
计划把101的环境整合到73上，以73的web为主

方案步骤

首先在两台机器都配置好/etc/hosts

1.备份数据库

mysqldump -uroot keystone > keystone_101bak.sql
mysqldump -uroot keystone > keystone_73bak.sql
确保配置前两个环境都是OK的

2.region重命名

101作为regiontwo,在101上
region表添加regiontwo条目, 并将所有endpoin设为regiontwo

mysql -uroot -e “insert into keystone.region(id,parent_region_id,extra) values (‘regiontwo’,NULL,’{}’);”

update endpoint set region_id=’regiontwo’;

[[email protected] ~]# openstack endpoint list

导出regiontwo的keystone的service和endpoint表
mysqldump -uroot keystone endpoint > endpoint_101.sql
mysqldump -uroot keystone service > service_101.sql
修改导出的两个表
删除导出数据表文件中的DROP 条目，去掉create语句（因为后面会将regiontwo导出的表添加导入到regionOne中，所以不能覆盖）

regionOne的设置

keystone数据库的region添加regiontwo条目

mysql -uroot -e “insert into keystone.region(id,parent_region_id,extra) values (‘regiontwo’,NULL,’{}’);”

mysql -uroot -e “select * from keystone.region;”
将regiontwo的endpoint和service表导入到regionOne中
mysql -uroot keystone < endpoint_101.sql
mysql -uroot keystone < service_101.sql

修改数据库，将导入的regiontwo的keystone的endpoint url（35357和5000端口）
地址修改为regionone

MariaDB [keystone]> update endpoint set url = “http://server73.e3cloud:5000/v3/” where url=”http://server101.e3cloud.com:5000/v3/”;
Query OK, 2 rows affected (0.00 sec)
Rows matched: 2 Changed: 2 Warnings: 0

MariaDB [keystone]> update endpoint set url = “http://server73.e3cloud:35357/v3/” where url=”http://server101.e3cloud.com:35357/v3/”;
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0

修改ADMIN PASSWORD
如果两个环境ADMIN密码不同，则应该修改
本次实验两个环境admin密码相同

重启两个服务器

登录即可看到效果
