rhel 6.6 download




Open a second File Explorer window and go to the directory where the Gradle distribution was downloaded. Double-click the ZIP archive to expose the content. Drag the content folder gradle-7.6 to your newly created C:\Gradle folder.


The Red Hat package manager (yum) provides the simplest and most comprehensive way to install Couchbase Server on Red Hat Enterprise and CentOS platforms.This method involves downloading and installing a small meta package from Couchbase, which yum can then use to automatically download and install Couchbase Server and all of its dependencies.


Choosing the right NCL binary for yourLinux systemDealing with missing libgfortran issueDealing with missing libxxx.so filesInstalling other software for LinuxFull list of available binariesChoosing the right NCL binary for your Linux systemIf you are installing pre-compiled NCL binaries on a Linux system,there are a number of binaries tochoose from. The binary filenames contain the type of Linux it was built on(RedHat/RHEL, Debian, CentOS, SuSE Linux), the "bitness" (32-bit or64-bit), and which version of the GNU or Intel compilers it wascompiled with. The binary filenames look like this:ncl_ncarg-6.6.2.Linux_RHEL6.4_x86_64_gnu472.tar.gzThe above binary was compiled on a 64-bit RedHat release 6.4system using GNU compilers version 4.7.2.If you are not sure which Linux binary to download, we recommendtrying one of these two binaries if youneed OPeNDAP support:ncl_ncarg-6.6.2-CentOS6.8_64bit_gnu447.tar.gzncl_ncarg-6.6.2-RHEL6.4_64bit_gnu447.tar.gzor one of these two binaries if you don't need OPeNDAP support:ncl_ncarg-6.6.2-CentOS6.8_64bit_nodap_gnu447.tar.gzncl_ncarg-6.6.2-RHEL6.4_64bit_nodap_gnu447.tar.gzIf you want to download a Linux binary that is close to the kind ofsystem you have, then type the following commands from a terminalwindow to get the type of system you have (32-bit or 64-bit), theflavor of LINUX you are running (RedHat/RHEL, Debian, CentOS, etc),and the version of gcc and gfortran: uname -m cat /etc/issue lsb_release -d gcc --versionFor example, if the above commands report "x86_64", "Debian 8", and"4.7.2", then you should download one of these binaries:ncl_ncarg-6.6.2.Linux_Debian8.6_x86_64_gnu492.tar.gzncl_ncarg-6.6.2.Linux_Debian8.6_x86_64_nodap_gnu492.tar.gzYou must match the bitness (32-bit or 64-bit). You can't use an"x86_64" binary on a system whose "uname -m" reports "i686".Secondly it's important to try to match your flavor of Linux ifpossible, and then match your version of gcc as close as possible.If your flavor of Linux or "bitness" doesn't match, then you canusually use one of the other ones. For example, if you have a CentOSor Fedora system, then try a RedHat binary. If you have a Ubuntusystem, try a Debian binary.If you run into a problem, pleaseemail ncl-install (youmust subscribefirst).Dealing with missing libgfortran issueFor most Linux binaries, NCL was built using gcc and gfortran. Thismay cause a dependency on a file called "libgfortran.so.x".If you have a different version of gfortran installed on your systemthan what NCL was built with, then you may get an error message that"libgfortran.so.x can't be found".If you see this, then you can try one of these things:Trying googling part of the error message that you're getting,along the flavor of LINUX.c for example, "CentOS cannot openlibgfortran.so.1". You will usually get several hits with lots ofgood suggestions.Install the version of gfortran that your version of NCL was builtwith. (It is possible to have multiple versions of gfortran installedon the same system without conflict.)If you are using Debian or Ubuntu, you can use the "apt-file"command (you may need to install it first) to search for a packagethat contains the missing libgfortran file ("libgfortran.so.3" inthis example): sudo apt-get install apt-file sudo apt-file update apt-file search libgfortran.so.3If you are using Red Hat or CentOS, you can use the "yum provides"command to search for a package that contains the libgfortran file: yum provides "*/libgfortran.so.3"Try to find the libgfortran.so.x file that it iscomplaining about. You can try the "locate" command.For example if the file is "libgfortran.so.1": locate libgfortran.so.1If found, you can add this path to your LD_LIBRARY_PATH environment variable.Important note: it is generally recommended that you do notdirectly set LD_LIBRARY_PATH. If you have to do this, it may mean thatgfortran may not be installed correctly on your system, and settingLD_LIBRARY_PATH is just a kludgy work-around. However, if you justcan't get it to work, then read on.For example, if "libgfortran.so.1" is the file you need, andit is in /usr/local/lib, then look at the instructionsbelow, depending on what shell you are running, and dependingon whether LD_LIBRARY_PATH is already set: env grep LD_LIBRARY_PATHFrom csh or tcsh, if not set: setenv LD_LIBRARY_PATH /usr/local/libFrom csh or tcsh, if already set: setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:/usr/local/libFrom bash or ksh, if not set: export LD_LIBRARY_PATH=/usr/local/libFrom bash or ksh, if already set: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/libFrom sh, if not set: LD_LIBRARY_PATH=/usr/local/lib export LD_LIBRARY_PATHFrom sh, if already set: LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib export LD_LIBRARY_PATHIf all else fails, then send email to ncl-install@ucar.edu. You needto be amember in order to post.Dealing with missing libxxx.so filesSome of the NCL binaries are OPeNDAP-enabled, which meansthere are a number of dependencies on shared libraries. If you try torun "ncl" and get one or more errors about not finding"libxxx.so" files, then you can try a few things.If you don't need OPenDAP support, then you can try downloading anon-OPenDAP enabled binary.If you need OPeNDAP support, you may need to install the "OpenSSL"software on your system, or find where it resides on your system andpoint to it.To look for a particular missing file, try using the "locate" command: locate libcrypto.so.0.9.8If you see the file, then read the previous section on the libgfortran issue to see how to point yourLD_LIBRARY_PATH environment variable to this location.If you can't find this file, then you may need to installOpenSSL on your system.For example, on some Linux systems, you may be able to type: yum install opensslor apt-get openssl apt-get install opensslFor further information and more links about where to find software,see the previous section on dealing with the missing libgfortran issue. You may simply need to setyour LD_LIBRARY_PATH environment variable, or you may need to installsome system libraries.Installing other software for Linux systemscairo, X11, and other dependent libraries - you need anX11 server in order to run ncl and display output to an X11 library,and you need the cairo, X11, and other development libraries in orderto build NCL from source code.Getting the development libraries on your system depends on what kindof Linux system you have. The commands below are samples of the typesof commands you can use to install the required software. apt-get install x11-dev apt-get install xorg-dev apt-get install libx11-dev apt-get install libcairo-devel yum install libX11-devel yum install cairo-develIf you find other libraries are missing, like "bz2", then you may needadditional libraries: apt-get install libbz2-dev yum install libbz2-devtcsh/csh - you need tcsh or csh if you are trying to run oneof the shell applications like ng4ex or nhlcc.You can install these shells with a command like: apt-get install cshor yum install tcsh If any of these instructions are out-of-date, please send emailto ncl-install.


You can download source code packages and Windows installers which are automatically created each time code is checked into the source code repository. These packages are available in the automated build section of our download area.


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.


PLEASE NOTE: Red Hat Linux is no longer a supported platform and may no longer be available for download. You should consider one of the following options:For a supported version of Red Hat: Red Hat Enterprise LinuxFor a no cost product sponsored by Red Hat: FedoraThere are also a variety of RHEL rebuilds available: CentOS and Scientific Linux are examples.Old Description: What began as a better way to build software--openness, transparency, collaboration--soon shifted the balance of power in an entire industry. The revolution continues. Today Red Hat is the world`s most trusted provider of Linux and open source technology. And that technology is pervasive, running systems of all sizes, and, more than ever, powering mission-critical computing in the enterprise.


Additionally, all binaries are signed by thejq Package Signing Key.The signatures can be found undersig/v1.x/*.asc.The signatures for jq 1.6 are insig/v1.5/*.asc.The signatures for jq 1.5 are insig/v1.5/*.asc.You can use GnuPG to verify a signature by downloadingthe signature and running gpg --verify signature.asc.


Throughout this section we will be using the wget command to download the Oracle Java software packages. wget may not be included by default on your Linux distribution, so in order to follow along you will need to install it by running:


Note: In order to install Oracle Java, you will need to go to the Oracle Java Downloads Page, accept the license agreement, and copy the download link of the appropriate Linux x86 .rpm package. Substitute the copied download link in place of the highlighted part of the wget command. 2ff7e9595c
