从单独的应用程序连接到mysql数据库

[英]Connecting to a mysql database from a separate Application

First time using OpenShift, and I've read that I am able to connect to a database on a different application under my account. 第一次使用OpenShift,并且我读到可以在我的帐户下连接到其他应用程序上的数据库。

I have APPLICATION A that is a Ruby/MySQL project. 我有一个Ruby / MySQL项目的APPLICATIONA。 I have APPLICATION B that is a PHP project. 我有一个PHP项目“ APPLICATION B”。

I'd like to connect to my APPLICATION A MySQL database from my APPLICATION B PHP script. 我想从我的APPLICATION B PHP脚本连接到我的APPLICATION A MySQL数据库。 When doing an rhc apps command, I can see that my connection URL reads: 当执行rhc apps命令时,我可以看到我的连接URL显示为:

Connection URL: mysql://$OPENSHIFT_MYSQLDB_HOST:$OPENSHIFT_MYSQLDB_PORT

When looking at my environment variables on my APPLICATION A server, I see they are: 在我的APPLICATION A服务器上查看环境变量时,我看到它们是:

OPENSHIFT_MYSQLDB_PORT=3306
OPENSHIFT_MYSQL_HOST=127.7.171.129

But when I try to connect: 但是当我尝试连接时:

$db = new mysqli('127.7.171.129', 'adminuser', 'adminpw', 'productiondb',3306);

And I dump out this: 我把这个丢掉了:

object(mysqli)#1 (17) {
  ["affected_rows"]=>
  NULL
  ["client_info"]=>
  NULL
  ["client_version"]=>
  int(50169)
  ["connect_errno"]=>
  int(2005)
  ["connect_error"]=>
  string(57) "Unknown MySQL server host 'http://127.7.171.129' (1)"
  ["errno"]=>
  NULL
  ["error"]=>
  NULL
  ["field_count"]=>
  NULL
  ["host_info"]=>
  NULL
  ["info"]=>
  NULL
  ["insert_id"]=>
  NULL
  ["server_info"]=>
  NULL
  ["server_version"]=>
  NULL
  ["sqlstate"]=>
  NULL
  ["protocol_version"]=>
  NULL
  ["thread_id"]=>
  NULL
  ["warning_count"]=>
  NULL
}

Here's a KB article that has a couple of suggestions: https://www.openshift.com/kb/kb-e1051-how-do-i-connect-multiple-applications-to-one-database 这是一篇包含一些建议的知识库文章: https : //www.openshift.com/kb/kb-e1051-how-do-i-connect-multiple-applications-to-one-database
