Rancher 忘记用户名密码

  刚刚开始学习Rancher，前一分钟创建的用户名和密码下一秒就忘了。也是醉了····不过还好可以通过以下方式重新设置，摘自官网的文章http://docs.rancher.com/rancher/faqs/troubleshooting/#help-i-turned-on-access-control-and-can-no-longer-access-rancher-how-do-i-reset-rancher-to-disable-access-control

Authentication

HELP! I TURNED ON ACCESS CONTROL AND CAN NO LONGER ACCESS RANCHER. HOW DO I RESET RANCHER TO DISABLE ACCESS CONTROL?

If something goes wrong with your authentication (like your GitHub authentication getting corrupted), then you may be locked out of Rancher. To re-gain access to Rancher, you’ll need to turn off Access Control in the database. In order to do so, you’ll need access to the machine that is running Rancher Server.

$ docker exec -it <rancher_server_container_ID> mysql

NOTE:

The <rancher_server_container_ID> will be the container that has the Rancher database. If you upgraded and created a Rancher data container, you’ll need to use the ID of the Rancher data container instead of the Rancher server container.

Access the cattle database.

mysql> use cattle;

Review the setting table.

mysql> select * from setting;

Update the api.security.enabled to false. This change will turn off access control and anyone can access Rancher server with the UI/API.

mysql> update setting set value="false" where name="api.security.enabled";

Delete the client ID and secret key for GitHub.

mysql> update setting set value="" where name="api.auth.github.client.id";
mysql> update setting set value="" where name="api.auth.github.client.secret";

Confirm the changes have been made in the setting table.

mysql> select * from setting;

It may take ~1 minute before the authentication will be turned off in the UI, but you will be able to refresh the webpage and access Rancher with access control turned off.

操作完后等一分钟左右再次刷新Rancher server界面就可以了
