how install rvm on RHL7 using centos repo - centos

How to install rvm(ruby) on RHL7 using centos repo.
I know if we are using centos repository we should be using centos OS and not RedHat, but we have a proprietary software that require Redhat.
when I try to install ruby 1.93 using rvm I got this:
rvm install 1.9.3
Searching for binary rubies, this might take some time.
No binary rubies available for: redhat/6/x86_64/ruby-1.9.3-p551.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for redhat.
Unable to locate SystemId file. Is this system registered?
Our client does not have registered system with redhat, So I did configure centos repository.
But how can I tell RVM to use this centos repository?

I managed the problem running:
rvm autolibs read-only
In that way rvm do not try to download the dependencies from redhat. But it tell us what is missing, so we can install what is missing manually with yum install from centos repository.

RedHat uses the concept of software collection to offer update packages for Ruby, Python, etc:
softwarecollections
For your case, they have software collection for Ruby193 and Ruby22.
On each page you will find instructions on how to use it.

How do I get PHP 7.1 to talk to PostgreSQL on RHEL 7?

Running a Laravel installation on a RedHat Enterprise Linux 7 server using PHP 7.1. I can see php-pgsql.x86_64 listed in the available yum packages, but it doesn't appear to be compatible with PHP 7.1 (and indeed is listed as version 5.4.16-43.el7_4.1).
On a lark, I tried installing it anyway and physically moved the pgsql.ini and pdo_pgsql.ini files from /etc/php.d into the relevant PHP 7.1 folder /etc/opt/rh/rh-php71/php.d/ (and did the same with the .so files they reference), but that returns an error indicating that the package couldn't be read (undefined symbol: file_globals_id in Unknown on line 0).
Has anyone managed to get PHP 7.1 talking to PostgreSQL on RHEL 7?
The sysadmin who originally created the server for me set me straight. The problem was I was looking in the wrong repository for the packages I needed for my particular PHP installation. Running the following two commands did the trick:
sudo yum install --disablerepo=* --enablerepo=rhui-REGION-rhel-server-rhscl rh-php71-php-odbc
sudo yum install --disablerepo=* --enablerepo=rhui-REGION-rhel-server-rhscl rh-php71-php-pgsql
We then added those two packages to the Ansible playbook so future generations would not suffer needlessly.

Exception: Failed to solve dependencies: 1:perl-JSON-XS-2.27-2.el6.x86_64 requires perl(:MODULE_COMPAT_5.10.1)

Scenario: new installation of plesk 12.5 on centOS 7 into an OpenVZ container (proxmox):
Installing Plesk 12.5 I get the following error:
Exception: Failed to solve dependencies: 1:perl-JSON-XS-2.27-2.el6.x86_64 requires perl(:MODULE_COMPAT_5.10.1)
any tips?
You mention CentOS 7, but the package you are attempting to install (perl-JSON-XS-2.27-2.el6.x86_64) is for RedHat/CentOS 6, denoted by the el6 tag in the package name.
In any case, the issue appears to be due to not having the correct repositories available in yum to solve all necessary dependencies. Plesk maintains their own yum repositories to provide all of the necessary packages. Usually the install script will handle this for you (the install script is just a quick way to obtain the Plesk autoinstaller which should have the proper source repository configured).
I would suggest you examine the currently configured yum repositories in your container and make sure there are no conflicting repositories. Depending on the components you are installing with Plesk, it will want to manage nginx, apache, mysql, php, and some perl components so make sure you do not have yum repositories attempting to install related packages. Also, if you are indeed using CentOS 7, make sure you have no repositories attempting to install CentOS 6 packages. This bash one-liner should print out all the configured yum repository URLs so you can quickly scan if any are using the wrong version:
grep -re '^\(mirrorlist\|baseurl\)' /etc/yum.repos.d/
If you need further troubleshooting help, please include how you are attempting to install Plesk.

If my CentOS 7.2 box has vagrant 1.7.2, can I just run the 1.8.1 rpm to get vagrant 1.8.1?

I have a CentOS 7.2 laptop. I have VirtualBox 5.0.x installed on it. Out of the box, it appears that I have Vagrant 1.7.2. Apparently this doesn't support VirtualBox 5.0.x, but it appears that version 1.8.1 does. What is the proper way to get access to 1.8.1? There is an installation rpm for 1.8.1 that I've downloaded, I can run this with "rpm", but do I have to do anything else before I do that?
Use Software Collections to get Vagrant 1.8.1 on CentOS: Vagrant 1.8 by Software Collections (the linked page contains instructions on how to do that). That will give you a build tested by the CentOS project.
As a sidenote: If you downloaded a standalone RPM package (presumably directly from the Vagrant project) and wish to install it, do it using the yum package manager, not rpm -- yum takes care of dependencies.

postgresql-9.3-pljava-gcj for 64 bit architecture

I need to install pljava for postgresql 9.3 on Ubuntu 14.04. I installed the 64bit version of postgre using the apt-get packet manager of Ubuntu, and I tried installing pljava in the same way
sudo apt-get install postgresql-9.3-pljava-gcj
but it gives me the "unmet dependencies error"
The following packages have unmet dependencies:
postgresql-9.3-pljava-gcj:i386 : Depends: postgresql-9.3:i386 but it is not going to be installed
Apparently, there's no version of pljava for 64bit architectures of pljava for postgresql 9.3. Also searching the Web led me to this conclusion (https://launchpad.net/ubuntu/+source/postgresql-pljava/1.4.3-3 - see the "not build" versions of the packet).
Now, my problem is that I have to use a 64bit version of postgresql-9.3, and I definitely need pljava to embed some "java triggering" inside the db. Does anyone know any solution to this issue? Can I use pljava-9.1 with postgresql-9.3? Anything else?
Thanks a lot
There is no maintained PL/JAVA package for Ubuntu anymore. The package you mentioned is using a too old version of PL/JAVA, depending on gcj. It is highly recommended to use PL/JAVA version 1.5.0, using a recent Oracle or OpenJDK java version.
The sad news is you have to build it yourself. For instructions, see
https://tada.github.io/pljava/build/build.html (building)
https://tada.github.io/pljava/install/install.html (installing)
At the time this question was asked, it was true that there were not maintained PL/Java packages for Ubuntu.
Just to update the story, more recently there are. They can be found in the PGDG apt repository.

yum syntax to get jboss on centos?

What's the syntax to get JBoss AS (latest, say 7.1.1) on CentOS (latest, 6.5)? I tried
su
yum install jbossas
but get the error
No package jbossas available.
Error: Nothing to do
Either I need to add some repos to yum or the package name is wrong. I understand I can just unzip the .zip into /bin/ per this post, but that would lead to messy/orphaned files in upgrades, so I'm looking for open, community repos that might have the jboss-as binaries.
So far my knowledge, you can not do this using yum at CentOS. Also, you can not upgrade from one version of JBoss into another one automatically(like any software or compiler do it automatically). Things are totally different here. For example JBoss 5.1 is having a totally different directory architecture compare to JBoss 7.1.
