进入管理员登陆页面：
http://127.0.0.1:8080/resin-admin/index.php
注册一个管理员账号，如jack，会出现如下提示：
A login configuration file has been written under the name admin-users.xml.generated in the same directory as your resin.xml file. Simply rename this file to admin-users.xml to install your login.
Or cut and paste the following into the admin-users.xml
<resin:AdminAuthenticator xmlns="http://caucho.com/ns/resin"
xmlns:resin="urn:java:com.caucho.resin">
<user name="jack" password="NNZXjZAbba/nmoAB0fiIfQ=="/>
</resin:AdminAuthenticator>
By default, access to the administration application is limited to the localhost. The default behaviour can be changed in the resin.xml file. To enable access to clients other than localhost:
<resin:set var="resin_admin_external" value="true"/>
Once the file has been saved, you can continue to the administration area. This will trigger a server restart, so just refresh your browser until you see the login page again.
When prompted, use the username and password you provided.
仔细看这段文字就会明白，这段话是说：
在conf目录下生成一个文件admin-users.xml.generated，文件名改为admin-users.xml，就可以了。
或是将下面这个Xml片段插入admin-users.xml文件中也行
<resin:AdminAuthenticator xmlns="http://caucho.com/ns/resin"
xmlns:resin="urn:java:com.caucho.resin">
<user name="jack" password="NNZXjZAbba/nmoAB0fiIfQ=="/>
</resin:AdminAuthenticator>
