I am very new to the yum package system, so please forgive my rookie question.
I am using an Amazon Linux AMI on EC2, would like to install a package, say opencv with yum:
$ sudo yum install opencv
Loaded plugins: priorities, update-motd, upgrade-helper
amzn-main/latest | 2.1 kB 00:00
amzn-updates/latest | 2.3 kB 00:00
No package opencv available.
Error: Nothing to do
It appears the repository yum knows does not contain a opencv distribution. I am wondering whether there is a way to tell yum to find this package at certain third-party repository, and if so, is there a good place to search for repository that contains particular packages? Any pointer will be greatly appreciated!
Check if epel repo is disabled by running:
sudo yum repolist all
If you see epel is disabled, then enable it and search:
sudo yum --enablerepo=epel search opencv
If you find it, then install it. If you don't find it, you may to download the source, build and install it. Should be straightforward.

How can I install both of them on CentOS 7? They both depend on each other. The machine is not connected to the internet.

However, for i686 (yes, I need both unfortunately) I have tried to combine all packages into single command, lots of other dependencies appeared. I have tried to install 2.17-292 like I did for x86_64, this is the final output with errors. Before this last command, dependency errors appeared all the time, this is the first different error.

Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was
14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"
One of the configured repositories failed (Unknown),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=<repoid> ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable <repoid>
or
subscription-manager repos --disable=<repoid>
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
Cannot find a valid baseurl for repo: base/7/x86_64
You can upgrade all the packages at the same time, using a command like this one:
sudo rpm -U glibc-2.17-317.el7.x86_64.rpm glibc-common-2.17-317.el7.x86_64.rpm
Or you can use yum update, like this:
sudo yum update --disablerepo="*" *.rpm
This has the advantage that packages not installed are not automatically installed by the upgrade (unless dependencies require it). --disablerepo="*" ensures that yum update does not try to download anything.
jlehtone in forums.centos.org solved my situation. I just needed to write
sudo rpm -i glibc-2.17-292.el7.i686.rpm nss-softokn-freebl-3.44.0-8.el7_7.i686.rpm nspr-4.25.0-2.el7_9.i686.rpm nss-util-3.53.1-1.el7_9.i686.rpm

I'm pretty new in AWS, I've tried to install PHP on my virtual machine, but it doesn't works, I get the error:

I don't know the reason of this, I already tried the comamnd yum update, but it doesn't help, please help me
PHP5 is quite old and is probably not available anymore in the YUM package manager.
Also I think the tutorial you are using is Debian/Ubuntu based.
Apache2 is called httpd24 in yum for instance.
That would look something like this:
sudo yum install -y httpd24 php72 mysql57-server php72-mysqlnd
Or if you are using the Amazon Linux 2 image, then use this command:
sudo amazon-linux-extras install -y lamp-mariadb10.2-php7.2 php7.2
To find out which specific image you are running:
cat /etc/system-release
Please check out the AWS documentation for an up-to-date tutorial on howto deploy your own LAMP-server:

My company has firewall rules for yum so we can use only rpm to install the softwares on the RHEL 6 SERVER. So, I got a task to install virtualbox 5.1 on it. i used the rpm from the virtualbox website and installed it, but it failed with 2 dependencies and i installed them also. Then i got the below error.I just googled that i need some kernel-devel rpms but i dono, what to do after that and what else i need to make the virtual box running.
# virtualbox
WARNING: The vboxdrv kernel module is not loaded. Either there is no module available for the current kernel (2.6.32-642.4.2.el6.x86_64) or it failed to load. Please recompile the kernel module and install it by
sudo /sbin/vboxconfig
You will not be able to start VMs until this problem is fixed.

There will be lot of dependencies while installing rpm's. you need to check one by one and install the RPM's. Is suggest you to build local yum repository which doesnt require internet. you should use rhel 6 iso file to build local repo. And download the virtual box rpm, and try to install it with yum utility. yum will use local repo for dependency resolution.

I have been searching the web hours on end for several days and I am unable to install psycopg2 library on my Linux machine (CentOS - 2.6.32-431.3.1.el6.x86_64 GNU/Linux).
I know that the problem is that I am missing the libpq header files since I am getting this message after attempting pip install psycopg2: libpq-fe.h: No such file or directory
http://initd.org/psycopg/docs/install.html#install-from-source
Almost all the articles I found pointed me to use apt-get on CentOS but apt-get is not a standard tool on CentOS 6.3 so I've been trying yum install instead.
However, every time I try to use sudo yum install to download something the package is not available. For example:
yum install postgresql-devel
Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Install Process
Loading mirror speeds from cached hostfile

No package postgresql-devel available.
Error: Nothing to do
I've tried this for:
yum install postgresql-server
yum install python-devel
service postgresql initdb
service postgresql start
yum install python-psycopg2
Any ideas? Without the the libpq header files I can't install the psycopg2 module that is necessary for my Python program. This is for Python 2.7.12. And PostgreSQL 9.3.13.
I had this exact issue on Fedora 2016.09 box on Amazon. I was able to install postgresql-devel via yum, but that didn't do the trick; the version seemed to be out of date.
I solved it using:
sudo yum install /usr/include/libpq-fe.h
This installs an updated version of postgresql-devel which allows psycopg2 to compile correctly when installing through pip.
I'm facing OSError on centos 7.
OSError: decoder jpeg not available
I tried many solutions for this but still facing same. How to solve this?
I have faced this problem with Python/Django in Ubuntu amazon server.
The solution was to recompile Pillow library after installing the following packagers:
libjpeg libjpeg-dev libfreetype6 libfreetype6-dev zlib1g-dev
Probably the package names are different in CentOS, but you can search in yum to get the right names.
That's important to notice that you must uninstall and reinstall Pillow, PIL or any library that depends on these packages.
Rômulo is correct; on CentOS 7, you're going to want to install a few pre-requisites. I also recommend installing EPEL (correct at time of writing):
# EPEL
echo 'Enabling Extra Packages for Enterprise Linux (EPEL) repository...'
yum install http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
# Install additional packages
yum install zlib-devel libjpeg-turbo-devel libpng giflib
Then give it a try again.
