Is there any workaround to lack of proxy port in OpenShift Online?
Why I need it? I've got three application gears. All of them run JBoss. One of them run additionaly MySql.
I need to make three ports (3306, 5445, 5455 - mysql and HornetQ) from gear with MySQL available to other gears (HornetQ to one and MySQL to another). Is there a way to do it?
If you create a scalable application then you can access MySQL gear from other applications. Lets suppose you create a scalable application using JBoss and MySQL then OpenShift would install MySQL and JBoss on separate gears.This would allow other applications to access the MySQL database.

I have a project with a Flask backend and Vue frontend. I want to deploy it to Heroku but using my own MySQL database from my own MySQL server, without using Heroku's dynos.
Is this possible?
That depends what you mean by
my own MySQL database from my own MySQL server, without using Heroku's dynos
If your MySQL server is accessible from the Internet, sure. Just point your application at it.
(Note that using one of Heroku's database addons does not mean using dynos. These services run as hosted services on the cloud, not on your dynos. JawsDB and ClearDB are both options and both have free tiers.)
If you're talking about something running inside a firewall, e.g. on your laptop, then this won't be possible without doing a bunch of network stuff. It's possible but I strongly urge you not to do this. It's easy to create security issues.
I have made a MySQL database on my local server.
I want to port this to Heroku. Would there be any way to do this without using ClearDB? ClearDB asks for account verification, credit card details etc. which I do not want to give. The rest of the application is hosted on Heroku, so I just need to migrate the database.
Would this be possible?
You have at least three options:
There are other Heroku addons that provide MySQL databases. I'm not sure if any of them let you get started without a credit card.
You could use a MySQL provider that's not explicitly supported by Heroku and point your application to it manually.
You could update your application to use PostgreSQL instead of MySQL and use Heroku's own Postgres service.
I am about to install WordPress on a Windows 2008 server - two load balanced servers with a UNC share. Web browsing using the server is out of the question (IT security policy) so using the Microsoft Web Platform Installer is also a non starter. I will therefore have to install it manually.
So far I have installed PHP (routine), but I now need to install MySQL and create a database. However, with these being two separate servers, what effect is this going to have on the database - will this require a database on each server? Will they remain in sync? Can the database itself be put in the UNC share?
In short, can anyone advise me whether this is possible and how to go about it?
Thanks
Install MySQL and create the database on the server which is supposed to have it - preferably a 3rd one or on the UNC. In the MySQL config, enable network connections via my.cnf, specifically the bind-address.
Both the PHP boxes should connect to that one MySQL db (using it's LAN ip address). (And yes, they would remain in sync since they connect to the same db.)
I need to review the mysql 5.5 server logs but I cannot find a way to get access them via ssh, sftp or mysqlworkbench. The mysql cartridge is in a scaled application. A solution?
There are a couple things here I'd like to point out that should provide some more information on how things work and how to get to the information you're looking for.
Scalable applications with DB's actually have the DB running in a separate gear than the application framework (for scaling purposes). For instance, if you ran rhc app show <appname> --gears for one of your scalable applications you would see that there are 2 gears being used and that the ssh information for each of them is different. So if you're just looking to take a quick look at your logs via ssh, you'll need to ssh into the appropriate gear to get to them.
You will need to use the rhc port-forward command to forward the right local ports to your database gear and then be able to connect mysqlworkbench from there.
I have checked almost all solutions both in Openshift forum and here in stackoverflow but couldn't solve the problem.
Here is the situation
I have a php server with load balancing in one gear.
I have a second gear for mysql server along with PhpMyAdmin. At present OpenShift does not support load balancing for PhpMyAdmin, so my second gear does not have any scaling feature.
Now I want to host a php app in first gear and the database in the second gear. So how do I connect them internally (would be better if I could do it without port forwarding)? I need all the commands from the beginning to the end unfortunately.
Thank you.
You should just add the mysql cartridge to your scaled application. It will still put the mysql database on it's own gear, but it will be accessible from your scaled application using the standard mysql environment variables. You can view those variables by sshing into your application and running env | grep mysql. If you decide to run your own second gear for the mysql database (you still had to install a web cartridge anyways to do that right?) then you will either HAVE to use port forwarding for direct access, or you will have to write an API on that server that will allow your application to access the mysql database.
