为了跑通那个HelloWorld。

上次一直不能通过帐号验证，所以今天继续注册一个帐号进行验证过程。

题外话：
注册过程中发现PlanetLab的全球站点中，我比较熟悉的高校中，台湾的高校都已经注册了，国内的话北京大学、华中科技大学等都还是Panding Registration，而清华大学和西安交通大学都已经激活了节点。

xxx <xxx@xxx.com> has signed up for a new PlanetLab account at Tsinghua University and has requested the following@H_502_39@roles: user.
To deny the request or enable the account,visit: https://www.planet-lab.org:443/db/persons/index.PHP?id=xxxx@H_502_39@ @H_502_39@ 然后我就去Login，但是不断地提示： Sorry. Unrecognized username or password. @H_502_39@ @H_502_39@没办法，我坚持不懈地登录，终于给出了不同的结果：
Unable to connect to database
This either means that the database information in your settings.PHP file is incorrect or we can't contact the Postgresql database server. This could mean your hosting provider's database server is down.
The Postgresql error was: pg_connect() [<a href='function.pg-connect'>function.pg-connect</a>]: Unable to connect to Postgresql server: FATAL: connection limit exceeded for non-superusers < is db.planet-lab.org .
- Are you sure you have the correct username and password?
- Are you sure that you have typed the correct hostname?
- Are you sure you have the correct database name?
- Are you sure that the database server is running?
For more help,see the Installation and upgrading handbook . If you are unsure what these terms mean you should probably contact your hosting provider.
上面提示说站点可能down掉了，或者我的用户名和密码不对吧？
无语阿，所以直接跑到PlanetLab欧洲网站上去出重新弄一遍，发现还是同样的问题，难道我rp有问题？
我还是再试试重置密码：
