If you have k3b (CentOS-4 users do, all other CentOS users do not by default) I recommend you use it. You want to use the Tools -> CD -> Burn CD Image or Tools -> DVD -> Burn DVD ISO Image option to write the ISO file to a CD/DVD. Now you can burn the ISO to a disk. Once you have verified the checksums of the ISO, you know you have a good download.

A version of up2date is also provided that does not connect to the upstream vendor, but instead connects to the CentOS Network (CN) for updates. Starting with CentOS 4, yum will import the key, but only after the user sees the key and can verify it is authentic.
How To Set Up and Use Yum. This article reviews setting up and using YUM repositories on a CentOS.
I made an example @ Github (//github. I used Cheetah(Python) as the first layer, as it have lot more features then Tenjin, and I’ve used Golang as the webserver (second layer). Although Golang is not the fastest TE I know, it’s fast enough and I really like Golang as a web server.
Also, the same steps should work on RHEL and Scientific Linux 7 systems too. This tutorial describes how to setup a local Yum repository on CentOS 7 system.
No repo config is provided. These packages have not been tested by the CentOS developers, and may not track upstream version releases very closely. On external public mirrors, ISOs may or may not be directly downloadable (at the discretion of the mirror owner). X falls into this category). These packages have undergone some basic testing, should track upstream release versions fairly closely and will never replace any core distribution package. UpdatesContains updates released for the CentOS distro. ContribPackages contributed by the CentOS Users, which do not overlap with any of the core Distribution packages. CRContains updates from the next point-release which went through basic QA but have not yet been released as a new CentOS point release. CentosplusPackages contributed by CentOS Developers and the Users. You should understand the implications of enabling and using packages from this repository. These packages might replace rpm’s included in the core Distribution. AddonsContains packages required in order to build the main Distribution or packages produced by SRPMS built in the main Distribution, but not included in the main Red Hat package tree (mysql-server in CentOS-3. On the main CentOS mirror sites ISOs cannot be downloaded directly, but we provide a Bittorent file for downloading. These packages are found at //debuginfo. Packages contained in the addons repository should be considered essentially a part of the core distribution, but may not be in the main Red Hat Package tree. DocsContains manuals and release notes for CentOS extrasPackages built and maintained by the CentOS developers that add functionality to the core distribution. DebuginfoContains RPMs with debugging symbols generated when the primary packages are built. IsosContains the ISOs for download. What are all the CentOS repositories (directories) and what is each one for. OsContains the base OS tree that is on the Main ISO files.
People regularly appear in CentOS support venues asserting that a PCI assessor, or a web driven scanning tool is reporting that they need to update to some specific version of software not shipped in CentOS. CentOS and its upstream are continuously updated, and the CVE’s addressed are reflected in the aforementioned changelog, so running a protective backup, updating, and rebooting or restarting the affected daemon service should address the matter. If a scan report is complaining about package versions, the person providing it is probably not doing it right, as the popular meme goes. Other approaches, such as using one keyed to package version numbers, are simply wrong. PCI does not mandate specific version levels, but rather freedom from known testable vulnerabilities, usually expressed in the shorthand CVE number fashion.
Instructions for setting up the Utter Ramblings Yum Repository for RHEL & CentOS.
If you need to make the selection of packages at install time, please use one of the other installation disks instead of the live isos. Once the image is copied to the hard disk, you can adjust the set of installed packages using yum as you would do on any other CentOS system. Installing CentOS from the live images is just a simple transfer of the image that exists already on the CD (or DVD).
Replace “good” with “bad”
echo “good good” | sed ‘s/good/bad/g’ output: bad bad
echo “good good” | tr ‘good’ ‘bad’ output: bddd bddd
tr is more like a mapping command, it’s like a set of rules:
The char “g=b”, the char “o=a”,”o=d” the last one will be the active one “o=d”.
Change ‘ ‘ to a new line:
echo “line1 line2” | tr ‘ ‘ ‘n’ output: line1 line1
echo “line1 line2” |sed -e ‘s/ss*/n/g’ output: line1 line1
As you can see tr is a lot easier for this job. Replace “hi” with “bye”
echo “hi hi” | sed ‘s/hi/bye/g’ output: bye bye
echo “hi hi” | tr ‘hi’ ‘bye’ output: by by
While sed can replace strings tr can only replace characters,
so with complete string replacement sed is the way to go.
To add an extra repository, place a definition file in the /etc/yum. D/ directory on your system.
