Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Un*x-like operating systems.
I have recently installed CentOS 7 (Minimal Install without GUI) and now I want to install a GUI environment in it. How can I install Desktop Environments on previously installed CentOS7 without reinstalling it? Rather than make use of the hacking of a startx command into a .xinitrc file, it's probably better to tell Systemd that you want to boot into a graphical GUI vs. Isn't it better to use Systemd commands to enable graphical mode rather than manually creating a symlink? Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count). Not the answer you're looking for?Browse other questions tagged centos gui desktop-environment or ask your own question.
In the Saturn V launch sequence, what defined COMMIT, and what happened between COMMIT and LIFTOFF? For this guide I will be using CentOS 6, but any RHEL distro should work with similar commands. Transmission can be installed quite easily through the repositories, however it is not part of the default Red Hat repositories. For simplicity sake you can always just following my guide with version as of time of this writing, as it will be updated when you do an upgrade anyways.
The reason for this error is because Transmission is setup by default to only accept connections from localhost.
I have the same issue, this is new, I am running centos 6 on a VPS – Did you find a solution ?
Jenkins is free and open source continues integration tool and it’s code is written in Java.
In case firewall is enabled on your Linux server then run the following commands to open jenkins related ports like 80 and 8080. Let’s first install git package on your machine on which you have installed Jenkins because Jenkins use git command to pull the GitHub project code. Specify the Project Description and Select Git option in Source Code Management Tab and specify the Web URL of your GitHub Project and its credentials. Netdata is a real-time performance monitoring solution, which used to monitor all our systems and applications on Linux PCs, servers or embedded devices. Netdata is a Linux daemon, which collects data in real time (per second) and presents a web site to view and analyze them. Netdata has been designed to be installed on every Linux system, without disrupting the installed applications on it. Netdata will work all the major Linux Distribution such as Gentoo, Arch Linux, Ubuntu, Debian, CentOS, Fedora, RHEL, SUSE, openSUSE, Alpine Linux & PLD Linux.
Make sure you have to install below prerequisites packages before proceed Netdata installation on your system. Netdata will listen with Port Number 19999 make sure you have to allow the port number on firewall level.


After the first PXE prompt appears press F8 and Enter keys to continue and then select Install Windows 7 from PXE menu. I'am a computer addicted guy, a fan of open source and linux based system software, have about 4 years experience with Linux distributions desktop, servers and bash scripting.
Yes, it can be done, but it requires multiple changes to dnsmasq configuration file , as well as on pxelinux.cfg file snd syslinux.
You would need efi64 or efi32 directories depending on what type or architecture you will boot-up to be copied inside tftp directory. You can but dnsmasq is not able to discriminate the offered NBP based on the client architecture.
Also, booting the pxe winpe image from network can take a large amount of time depending on client resources and net bandwidth.
Universal USB Installer aka UUI is a Live Linux USB Creator that allows you to choose from a selection of Linux Distributions to put on your USB Flash Drive.
Feel free to inform me of unlisted Live Linux distributions or version revisions, and I will do my best to update UUI to support them.
UUI Expects the Volume Label of your USB drive to be UUI in order for OpenSUSE, CentOS and several other distributions to boot. Your USB drive may be improperly formatted, contains more than one partition or MBR, or your BIOS is not properly detecting the USB drive and its firmware needs to be updated. Many Flash Drives ship USB-FDD formatted and some systems will not detect or even boot USB-FDD. If you're running a Windows Vista or 7 Installer from your USB, after the first reboot, remove the flash drive and let the pc complete from the hard disk.
When browsing for an ISO, UUI will only display ISO Files that match exactly what the tool is asking for. Auto Detection: If you run Universal USB Installer from the same directory containing an installable ISO, the script should Auto Detect the ISO and bypass step 2. This is arguably the better method since you're managing the state of the system directly through Systemd and its CLIs. Our focus is on advancing knowledge of services and software and keeping you up to date on the latest deals and news in the market. It provides the feature of continues build and deployment or in other words we can say it is a automation server. Whenever a new code is pushed on the GitHub project it will be automatically push to Jenkins workspace with new versions. Netdata written in C and is extremely lightweight with less than 1% CPU utilization of a single core. The presentation is also real-time and full of interactive charts that precisely render all collected values. On this second part, logon to a Windows 7 Operating System computer, go to Microsoft Download Center and download Windows Automated Installation Kit ISO image file by using the following link.
After AIK ISO image finishes downloading, mount the image using a Windows mount software (Daemon Tools Lite Free Edition will do the job) and install Windows Automated Installation Kit software. Now it’s time to build the Windows 7 Preinstallation Environment (WinPE) x86 boot image by issuing the following commands on Deployment Tools Command Prompt.


Although for this tutorial just the WinPE x86 Boot ISO Image is required, below you can find the commands to build PE Images for Windows 7 64-bit and Windows 8 architectures also. In order to boot and install Windows 7 via network and PXE server, first instruct the clients machines to boot over network by modifying BIOS device boot order or hit a custom key during BIOS post to select a network boot device. After WinPE image finishes loading, a customized minimal image of windows starts and a Command Prompt window will be displayed on screen. Use the following commands to start the installation process (replace the samba network address location and network drive letter accordingly) and continue with the installation process as you normally do it from a local DVD media.
If you want to install the 64-bit architecture, map the specific 64-bit network path using a different letter and continue the installation procedure by following the same steps explained above. In case the installation sources are configured with authentication use the following command switch to specify the username. After both architectures installation sources had been mapped you can change between them by switching to the designated network drive letter as presented in the screenshot below. Performing Windows installations over PXE and network has a lot of advantages, such as cutting down the installation time drastically, allowing the installation process to take place the same time on multiple machines without the need to use a physical installation media. You need to run a ISO image from PXE server or you need to automatically mount a ISO directly from PXE menu?

Jenkins are used where continues build and integration is going on for software development. We have already covered many more Monitoring Tools that are capable to presenting statistics of past performance but netdata is designed to be perfect for real-time performance troubleshooting. Out of the box, it comes with plugins that collect key system metrics and metrics of popular applications.
Also be aware that the client must have sufficient ram to load the image over network and the network sould operate properly without any congestion or packet loss. Simply choose a Live Linux Distribution, the ISO file, your Flash Drive and, Click Install. Please ensure that the Volume Label of your USB remains UUI if you expect distributions to boot!
If you are having a hard time getting your BIOS to detect your flash drive, you can try to format it as USB-HDD or USB-ZIP using BOOTICE (GET IT HERE), and then proceed to use Universal USB Installer to put your chosen Distro on USB. A dedicated Linux based Universal USB Installer is in the works (and will be finished as I have time).
Upon completion, you should have a ready to run bootable USB Flash Drive with your select operating system installed.
