install and configure solr in openshift - solr

I am trying to follow this link for setting up solr in Openshift, but I guess the version given in the example is old. the directories given in the documentation are not working properly.
So my question is, How to install Solr in Openshift using tomcat-7 or other Cartridges ?

Without knowing what errors your getting I would recommend taking a look at https://www.openshift.com/blogs/run-your-java-tomcat-application-for-free-on-openshifts-paas to get tomcat up and running. From there to deploy a war file its as simple as:
1) clone your repo
2) remove the pom.xml file from the root directory of your repo
3) add your war to the webapps/ dir of your repo
4) do git add/commit/push

You can use the following QuickStart from LogicalSpark to make things easier to get up and running with Solr in OpenShift:

GAE: No longer able to update my Gaelyk project due to appcfg losing support

Recently tried to update my Gaelyk project (yes, it's old, but it works well and I still use it), but Google App Engine will no longer accept the update. The error message returned is "Deployments using appcfg are no longer supported. See https://cloud.google.com/appengine/docs/deprecations". The thing is, I never used appcfg to deploy my application; I used Gaelyk and Gradle. But obviously Gaelyk must have used appcfg under the covers.
I did download the replacement Google Cloud SDK, but this new tool is not similar at all to how Gaelyk and Gradle worked. Is there anything I can do to get Gaelyk to work anymore? Or is Gaelyk just dead and I need to rewrite my application (like in Node.js or something instead of Groovy).
This will be hard, however I will try to help you as possible. I think you may try to migrate it somehow to app.yaml configuration of GAE.
I am not sure what plugins are used in the project. From Gaelyk temple project I can see that it's using appengine-geb which, according to the documentation, behind the scenes, is using gradle-appengine-plugin (there is wrong link on this doc, but proper is bellow).
On the github of gradle-appengine-plugin I have found following.
There is a note:
NOTE: All App Engine users are encouraged to transition to the new
gradle plugin for their projects.
And in FAQ part there is following information:
How do I deploy with gcloud?
If you're using gcloud to deploy your application, the newest version of app deploy > doesn't support war
directories, you will need to provide it with an app.yaml OR you can
use the appengineStage task to create a directory that is deployable
in /build/staged-app
$ ./gradlew appengineStage
$ gcloud app deploy build/staged-app/app.yaml --project [app id]
--version [some version]
NOTES:
You must explicitly define all config files your want to upload
(cron.yaml, etc)
This does not work with EAR formatted projects.
I think the best option will be to migrate to new appenine plugin or if not possible try to implement is with gcloud app deploy command crating the config files manually (at least app.yaml). And for this migration I can provide you this document.
I hope you will manage somehow...
I can confirm that Serge's answer on the Gaelyk Groups site works; the same procedure that he figured out also worked for me. To summarize:
Run gradlew appengineRun as run previously with Gaelyk.
Copy all jar files inside the build\exploded-app\WEB-INF\lib folder into a \src\main\webapp\web-inf\lib folder (for me the new lib folder did not exist previously).
To deploy, use the new required gcloud tool, and instead of running gradlew appengineUpdate (which fails now), instead run
gcloud app deploy appengine-web.xml where that XML file can be found in your webapp/WEB-INF directory. I navigated to that directory to run the gcloud command, but you can use a relative path there if your working directory is elsewhere. (There are a number of optional flags associated with the gcloud app deploy command, but I didn't need any of them.)
Serge needed to use these instructions to convert datastore-indexes.xml to index.yaml and run gcloud app deploy index.yaml, however, I didn't need to do this because I had no datastores.

GoogleAppEngine wordpress complains (Could not create directory) on update and plugin install

I have a problem updating wordpress or installing wordpress plugin in my local version of google app engine. I get the following message.
Downloading install package from
https://downloads.wordpress.org/plugin/event-espresso-decaf.4.8.38.decaf.zip…
Unpacking the package…
Could not create directory.
With the same code base I am able install plugin using MAMP (Macintosh, Apache, MySQL, and PHP). However fails with google Pyton script (dev_appserver.py).
I tried changing the permission of the file system by giving privilege to all user for write. Tried executing as sudo dev_appserver.py .. Followed the advice in other post, No luck.
Whats the problem here?, With MAMP all looks good in my local, but the same code break as I deploy to GAE (​appcfg.py -A APP-ID update app.yaml). Whats the problem here
Cannot write to file on Google App Engine Dev server with PHP?
Staring SDK 1.9.18, dev_appserver disables local file writing by default to better simulate the production environment. You can enable file writing by adding "google_app_engine.disable_readonly_filesystem=1" to your php.ini file.
I also wrote a blog post about running WordPress on App Engine flexible environment at:
https://wp.gaeflex.ninja/2016/03/25/using-wordpress-multisite/
Please give it a try too.

Which version of Eclipse works with PHP Google App Engine?

I've search in vain for about a month now and I can't get my PHP application pushed to Google App Engine, for the PHP platform. I've got the Java version set up nicely on my computer. I followed the instructions for GAE PHP here: https://developers.google.com/appengine/docs/php/gettingstarted/introduction
..but it's really confusing because it essentially tells me to install Eclipse made for PHP which is Luna, but the only versions of Eclipse that GAE supports is Kepler, Juno and Indigo (https://developers.google.com/eclipse/docs/getting_started), so I'm super confused.
I don't think you can install two different GAE plugins on a standard version of Eclipse (which is what I use for the Java GAE plugin).
I also tried (in vain, but it was worth a shot) to upload my app using my Java plugin/setup and obviously this was a terrible idea because all it does is just print the php script/code to the browser.
Any thoughts, brothas/sistas?
I have figured out how to push php files to GAE. There are essentially 3 ways.
Use appcfg.py. Run following command:
--appcfg.py update helloworld/, where helloworld is replaced by the name of the folder containing your project files. Make sure the path is relative to appcfg.py directory or an absolute path.
--Enter your Google username and password at the prompts.
**2. Use the App Engine Launcher, probably found in C:\Program Files (x86)\Google\google_appengine\launcher. Executable is called GoogleAppEngineLauncher.exe. Simply select the project in Launcher and click Deploy.
**3. Use Git. Create a local repository on your machine. Add a repo to your Github account, and follow these instructions: https://developers.google.com/appengine/docs/push-to-deploy#creating_a_cloud_project
**4. Use PhPStorm. Download PHPStorm for free for 30 days, or buy a student version/whatever version you quality for here: . Then follow these instructions: http://confluence.jetbrains.com/display/PhpStorm/Getting+Started+with+PhpStorm+as+Google+App+Engine+PHP+IDE. The only thing I haven't figured out is #5 - where to find the php-cgi.exe file. I can't provide a path for a file I don't have.
** denotes super easy and I have used successfully.
The Google Plugin for Eclipse is only for Java applications. For PHP applications, you'll want to use the Python/PHP SDK and either the command-line tools or the Launcher UI app for running the development server. You can still use Eclipse for editing your PHP source files.
RE #5 - "I can't provide a path for a file I don't have".
That was also my problem.
They are fond of pointing out that the SDK directory should contain dev_appserver.py and ‘google’ and ‘php’ packages but you don't find those in a simple search cause they are invisible. You have to muck through the installation directory.

Missing Files in Drupal 7 on OpenShift

I have a drupal installation running on OpenShift. I have been installing all modules and themes using git (commandline). However, I attempted to install the modules directly and the installation worked.
The problem that I now face is that when I attempt a pull request all I get is the modules and themes I had installed using the commandine and not the ones that I installed 'directly'.
Any one with a heads up on this?
OpenShift runs your code form a checkout of the git repository located at ~/app-root/repo within your gear. When you upload files using Drupal (instead of the git repository), the modules and themes are installed in this checked out directory and are not tracked in git.
I you are using a scaled application, I would recommend that copy the modules/themes and check them into git instead of the Drupal install method.
For now, to retrieve all your files you can try the rhc export command.
Thanks to #kraman above I got a hint of what to do.
I ran rhc snapshot save -a appname and got all the files. At least I know where to start off from since I can access the files.
A word of caution though for drupal users on openshift, just use git or sftp for pushing files and save yourself the headache.

Java | Maven - Plugins | Is it suggested to use cargo maven plugin in production environment ?

Currently we have a script that does maven build + tomcat deploy.
Deploying to tomcat involves stopping the server (force stop by setting CATALINA_PID), deleting war file and exploded folder from its webapps directory, copying new war file to webapps/ , deleting tomcat work directory and finally starting the server.
Can we achieve all/most of these using cargo-maven2 plugin (cleaning work/webapps ??)
[ I have a basic config that can be used to just stop,deploy and start ]
And is it good to use the plugin in production environment as well ? The documentation mentions that its useful for integration tests.
Can you guys share your thoughts on this?
Thanks,
Gayathri
As you already mentioned from the docs Cargo is for functional testing. For production you should use other things like puppet or chef. Furthermore Maven is not a deployment tool it's a build tool. From a technical point of view it's of course possible to use it in production but it's not intended.
