Installing Software On Centos 6



YUM Repositories are warehouses of Linux software (RPM package files). RPM package file is a Red Hat Package Manager file and enables quick and easy software installation on Red Hat/CentOS Linux. YUM Repositories hold a number of RPM package files and enable download and installation of new software on our VPS. YUM Repositories can hold RPM package files locally (local disk) or remotely (FTP, HTTP or HTTPS). YUM Configuration files hold the information required to successfully find and install software (RPM packages files) on our VPS.




Installing Software On Centos 6



Sometimes the software we want to install on our CentOS VPS is not available from default Official CentOS Repositories. In situations like this, we can use one of the additional (Non-Official) CentOS YUM Repositories listed above. Additional repositories sometimes hold newer versions of software packages than Official CentOS Repositories.


We can install new software on Red Hat/CentOS Linux with "yum install packagename" command from console. Running this command first checks for existing YUM Repository configuration files in /etc/yum.repos.d/ directory. It reads each YUM Repository configuration file to get the information required to download and install new software, resolves software dependencies and installs the required RPM package files.


CentOS DVD ISO holds a large number of software (RPM package files) which are available for installation during Red Hat/CentOS installation wizard. We can also use RPM package files from CentOS DVD ISO to create CentOS DVD ISO YUM Repository. This way we can install all of the software available on CentOS DVD ISO with "yum install packagename" command from VPS console even after we have completed Red Hat/CentOS installation wizard.


If RPM package files are not yet present on our VPS we need to transfer them to our cloud server via FTP or SSH - use software like WinSCP (free SFTP client and FTP) or similar. We can also download RPM package files directly to our VPS (internet connection needed) with "wget" command from console (please change HTTP link accordingly):


If there are any missing dependencies, you can install them from the standard repositories using yum or dnf. If your software requires other non-standard software, it will often be noted in the installation instructions.


Red Hat have pulled the plug on RHEL 6.x as of Nov 30th 2020 and as aresult CentOS 6 is now a dead version. The online yum repos for CentOS6 have been archived to vault.centos.org and there will be no moreupdates to it at all, ever.


YUM (Yellowdog Updater, Modified) allows you to easily download and install software, and simplifies your installations on a CVM instance, saving you time and efforts. With it, you only need to run the yum command to install software in the CentOS environment. Tencent Cloud provides a YUM repository so you can directly install software packages without adding sources.


The system will automatically search for the relevant software package and dependencies, and ask for your confirmation.For example, after you run the dnf install php command to install PHP, the following prompt will appear:2. Confirm that the software package is correct. Enter y and press Enter to start the installation.The Complete prompt indicates the installation is completed.

This post explains how to install NVIDIA proprietary drivers on CentOS 6. By default, CentOS 6 comes with nouveau drivers, which for 3D (OpenGL) rendering, is order of magnitude slower that NVIDIA's proprietary drivers. For instance, I had glxgear running at round 400 frames per second (FPS) before installing NVIDIA proprietary drivers and at around 1000 FPS after. So it pays to add this extra step to your CentOS 6 installation. Before we start, make sure you have all required packages installed:


Another difference, between CentOS 6 and earlier versions of CentoOS is that system-config-packages (Add/remove applications) is now called gpk-application. You need to run yum install gnome-packagekit if gpk-application is not installed in your system. Also, if you are planning to do OpenGL development run (source: www.centos.org - Forums - CentOS 6 - Software Support - Help me ..):


Installing updates for software packages or the kernel itself, is a highly recommended and beneficial task for system administrators; more especially when it comes to security updates or patches. While security vulnerabilities are discovered, the affected software must be updated so as to lessen any potential security risks to the whole system.


If you have not configured your system to install security patches or updates automatically, then you need to do it manually. In this article, we will show you how to check and install software updates on CentOS and RHEL distributions.


Trying using Windows X-server software such as Cygwin/X, which will allow you to connect to your Centos 6 computer in such a way that GUI application on linux will be displayed locally on your windows computer.


A VNC is slightly separate software. You would first need to setup a VNC server on the Centos 6 computer, and then install and connect to it with a VNC Client on windows. There are dozens of VNC server/clients out there, a Google search will reveal many. You will have to find one that work with the combination of OS-es you want to use.


You can download the RPM package andinstall it manually and manageupgrades completely manually. This is useful in situations such as installingDocker on air-gapped systems with no access to the internet.


If you come across issues after installing or uninstalling the AWS CLI, see Troubleshooting AWS CLI errors for troubleshooting steps. For the most relevant troubleshooting steps, see Command not found errors, The "aws --version" command returns a different version than you installed, and The "aws --version" command returns a version after uninstalling the AWS CLI.

There's a lot of flexibility in how you install an application on Linux. It's partly up to the software's developer to decide how to deliver it to you. In many cases, there's more than one "right" way to install something.


However, when an application is mission-critical, it's important that you get timely and reliable updates. The best way for that to happen is to install software from a central hub. On Red Hat Enterprise Linux (RHEL), that central hub for application installation and maintenance is the dnf (formerly known as yum) package manager.


Applications available on Red Hat's servers are divided into several software repositories. These include the BaseOS, AppStream, Red Hat Linux Builder (previously called CodeReady Linux Builder), and Supplementary repositories.


Sometimes you might need to install software that's been developed in-house or that's sent to you from a vendor or trusted developer. As long as an application is packaged in the RPM format, you can install it using dnf. As with software installed from a remote repository, using dnf records every file installed along with a package, so it can accurately update or remove those files later.


Instead of installing everything in a terminal, you can browse for desktop and graphical applications with the GNOME Software application. By default, GNOME Software displays only applications available from the BaseOS and AppStream repositories. You can view all available repositories with the Software repositories menu selection in the top-right corner of the browser.


Most Linux distributions and BSD variants have NGINX in the usual package repositories and they can be installed via whatever method is normally used to install software (apt on Debian, emerge on Gentoo, ports on FreeBSD, etc).


If you get an error about add-apt-repository not existing, you will want to install python-software-properties.For other Debian/Ubuntu based distributions, you can try the lucid variant of the PPA which is the most likely to work on older package sets:


There are three simple steps involved in the installation of the AMDGPU-Pro Driver: Download, Extract, and Install. The instructions to perform the installation are intended for a CentOS 6.8 and 7.3 installation and should take less than 10 minutes to complete. Before installing the driver, a quick note on how to check if your system already has AMDGPU-PRO installed. In addition, the recommended best practice is to bring the system up-to-date before starting the driver installation, with:


As an experimental feature, you can use SQLite in addition to PostgreSQL. You can also switch between SQLite and PostgreSQL by editing /etc/xdl/db.conf after installing the Linux VDA package. For manual installations, you must install SQLite and PostgreSQL manually before being able to switch between them.


Assume that you have installed and configured the Quest software on the Active Directory domain controllers, and have been granted administrative privileges to create computer objects in Active Directory.


After installing the Linux VDA on RHEL 7.x, run the sudo yum install -y python-websockify x11vnc command. The purpose is to install python-websockify and x11vnc manually for using the session shadowing feature. For more information, see Shadow sessions.


After installing the package, you must configure the Linux VDA by running the ctxsetup.sh script. Before making any changes, the script verifies the environment and ensures that all dependencies are installed. If necessary, you can rerun the script at any time to change settings. 041b061a72
