I'm trying to uninstall the current version of Eclipse IDE in my RHEL machine by simply deleting all the files like:
sudo rm -rf ~/.eclipse
sudo rm -rf ~/eclipse-workspace
I also tried
sudo yum remove 'eclipse*'
However, these didn't seem to solve the purpose.
Any help will be appreciated, thanks!
Applications on Linux systems are most often installed using so-called packages, which are managed by a package management system. In the case of RHEL, packages use the RPM format, and the package manager of choice is a tool called yum.
Both installation and removal of software (packages) should be done using yum, so as to allow the package management system keep track of all installed files and current status. Therefore, you shouldn't try to remove software by simply deleting files from the file system. Instead, use the yum command. See the RHEL System Admin Guide for a detailed explanation of how to use yum to search, install, upgrade, and remove packages: Working with Packages.
You have tried the correct command (yum remove <package-name>), but you need to use the correct package name. On RHEL 7.4, the latest version of Eclipse is available as a part of the DevTools channel, and the package name is rh-eclipse47 (see Enabling the Red Hat Developer Tools Repositories). Note that you may have also installed an older version, which would be, for example, rh-eclipse46.
To find out what is the name of the package you have installed, you can run, for example, the following command:
yum list installed | grep eclipse
There is also the possibility that you installed the software not from an RPM package but manually, e.g. from a .tar.gz file distrubuted from eclipse.org. If that's the case, you will need to use the uninstaller program supplied with that distribution of the software.
Write command as:
rpm -qa|grep eclipse
This will give a list of installed packages. Remove all the packages by giving below command:
rpm -e *package-name*
Done!!!

"Yum install monit" command by default will install 5.14 version. But Monit has released till 5.20 version
I tried with the below command for available packages
sudo yum --showduplicates list monit | expand
It shows up only one available package
Available Packages
monit.x86_64 5.14-1.el6
Are there any other option apart from manually downloading the tar using wget command and then installing it.
There used to be an RPM on the rpmforge/repoforge repos although these are presently down.
I believe these might resurface (based on this https://github.com/repoforge/rpms/issues/375) but in the mean time unless you want to build your own RPM for it you could grab this from a mirror.
Such as:
yum install https://www.insaneworks.co.jp/pub/el6/RPMS/x86_64/monit-5.20.0-1.el6.x86_64.rpm
I'm running Centos 6.7 on my server and am trying to install Erlang/Rabbitmq following these instructions:
Erlang Installation
RabbitMQ Installation
The trouble is that at time of writing these install Erlang 19.0 with RabbitMQ 3.6.3, which leads to a pretty major bug as far as my client who occasionally looks at the management interface to monitor queues is concerned.
The guidance in the error ticket is not to use erlang 19 until RabbitMQ 3.6.4 is released. But how can I install a specific version of Erlang?
These steps worked for me:
Go to the download page here: https://packages.erlang-solutions.com/erlang/
Select your appropriate package -- you can copy/peek the link then download it using wget.
Install it using rpm.
Example:
# Download erlang 19
$ wget http://packages.erlang-solutions.com/site/esl/esl-erlang/FLAVOUR_1_general/esl-erlang_19.0~centos~7_amd64.rpm
# Install
rpm -Uvh esl-erlang_19.0~centos~7_amd64.rpm
You can always build install from source.
Go to the Erlang.org Downloads page, pick your version from the right side.
From there you can follow the instructions. Although they are for Ubuntu, the commands are the same except for the dependencies part where you can use the command below to install what you need:
sudo yum install g++ openssl-devel unixodbc-devel autoconf ncurses-devel
Another option would be to use kerl, which is similar to rvm in some sense and very (very!) easy to use. It will let you install different Erlang versions and switch between them any time you want.
I prefer this approach instead of looking up packages myself (with possible incompatibilities in the dependencies required) or downloading and compiling everything myself every time I want to try a new Erlang version.
I have a brand new CentOS 6 box and wanted to install sphinx, in order to compile documents as generated by readthedocs.org i.e. rst files.
In a previous ubuntu box I was running
make html
and that would invoke the
sphinx-build
command and compile the documentation.
I downloaded the latest version of sphinx and installed it as such:
sudo wget http://sphinxsearch.com/files/sphinx-2.1.9-1.rhel6.x86_64.rpm
sudo localinstall sphinx-2.1.9-1.rhel6.x86_64.rpm
Everything seems to be fine but sphinx-build is nowhere to be found.
Any pointers are more than appreciated.
You are mixing up two different tools named Sphinx: the full text search server (http://sphinxsearch.com/) and the documentaton generator (http://sphinx-doc.org/). You need the latter tool in order to compile documents usingsphinx-build.
You can also install rpm package of sphinx (Python documentation generator) with yum at CentOS 6 using:
yum install python-sphinx.noarch
at Fedora 20 using:
yum install python-sphinx-doc.noarch
A short addup, according to offical document, one just need to run
pip install Sphinx to install the python documentation generator, sphinx. Or it can be downloaded from distribution package.
I would like to change some code in one element X in gstreamer ugly plugin and rebuild and use it.
How I can do it?
I have gstreamer-0.10 and installed gstreamer-ugly plugin.
I would like to download only gstreamer0-10 ugly plugin code and change it and would like to use the new lib file. How I can do it?
unfortunately gstreamer-ugly depends on a lot of stuff in at least libgstreamer and plugins-base (if you're using linux and your distro provides *-dev packages as debian/ubuntu does).
If you're on debian you could use dpkg-buildpackage after checking out the source using apt-source. The big advantage here is that all the build dependencies can be easily installed.
The manual way will probably need you to first build all the other gstreamer packages have a close look on what ./configure tells you
I'm workin on debian and have already built gstreamer+plugins to backport the recent ones to ubuntu (although I'm not sure if I did it in a best-practice way ;) )
/edit: I'll try to cover the basic steps for ubuntu here:
add the source repositories to apt (check the "source code" checkbox in the ubuntu software center's "software sources" tool
sudo apt-get install dpkg-dev devscripts
sudo apt-get build-dep gst-plugins-ugly0.10
apt-get source gst-plugins-ugly0.10
change to the newly created gst-plugins-base* folder
dpkg-buildpackage (and make sure it works)
change the source to your needs
you can rebuild it any time using dpkg-buildpackage (to simply see if it compiles make might be faster though). This creates a .deb file in the parent folder that you can simply install using dpkg -i
If it's a useful change you might want to get in touch with the gstreamer-devs ;)
On a debian system, run apt-get build-dep gstreamer0.10-plugins-ugly to get all the build dependencies for that package. After that you can build the package from git, source tarball or even rebuild the debian package (using dkgp-buildpackage).
i have installed clutter-1.0 from gnome site using terminal.
But when i run the application, error is notified as libcluttermm-1.0 not found. Has this
library not available as of now. if not what is the alternative that i can use.
What did you install exactly? libcluttermm (C++ interface to Clutter) is provided by the cluttermm package. On my Fedora system, I ran:
# yum install cluttermm
# locate libcluttermm
/usr/lib/libcluttermm-1.0.so.0
/usr/lib/libcluttermm-1.0.so.0.0.0
Of course, if you are doing development against it install cluttermm-devel instead.
Use libclutter instead, as libcluttermm is not in Ubuntu repositories.
