not able to install contextBroker via yum on CentOs7 - centos7

HI everybody i am using CentOs7 and havae some troubles with the installation of the contextBroker. I followed the installation on the added the Fiware Repo in my yum repo.
Here is a list of my yum repo:
repo id repo name status
base/7/x86_64 CentOS-7 - Base 9,007
epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 10,368
extras/7/x86_64 CentOS-7 - Extras 356
fiware Fiware Repository 176
mongodb MongoDB repo 279
updates/7/x86_64 CentOS-7 - Updates 2,070
repolist: 22,256
I am always getting an error message that there are some failed dependencies
libboost_filesystem-mt.so.5()(64bit) is needed by contextBroker-0.15.0-1.x86_64
libboost_system-mt.so.5()(64bit) is needed by contextBroker-0.15.0-1.x86_64
libboost_thread-mt.so.5()(64bit) is needed by contextBroker-0.15.0-1.x86_64
Here is the output of my config file for the fiware.repo
[fiware]
name=Fiware Repository
#baseurl=http://repositories.lab.fiware.org/repo/rpm/$releasever
baseurl=http://repositories.lab.fiware.org/repo/rpm/x86_64/
gpgcheck=0
enabled=1
I found a possible solution under this link, but unfortunately this is not working. In the comment section there is an entry which says that there is a problem with CentOs7 but that doesn`t solve my problem
Btw: this is also not working Boost-Libboost is needed in Centos7 (ContexBroker)
So my question is, did someone installed the contextBroker on CentOs7 via yum and if he/she did how can i solve this problem ?

As you mention, there isn't official support for CentOS 7 at the present moment. However, you could do the following to get a running binary with contextBroker in your CentOS 7 system (actually, this a "quick and dirty" receipt based on the build from sources procedure documented in the Orion manual):
sudo yum install git wget
wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo rpm -i epel-release-latest-7.noarch.rpm
sudo yum install make cmake gcc-c++ scons
sudo yum install boost-devel libcurl-devel gnutls-devel libgcrypt-devel libuuid-devel
# Install mongoDB driver as described in the documentation
# Install rapidjson as described in the documentation
# Install libmicrohttpd as described in the documentation
mkdir ~/src
cd ~/src
git clone https://github.com/telefonicaid/fiware-orion.git
cd fiware-orion
# optionally, you can set an specific version with a checkout command
# e.g. 'git checkout 1.2.1'. Otherwise, you will build the latest
# code from develop branch
make
BUILD_RELEASE/src/app/contextBroker/contextBroker --version
Moreover, you can use the following to generate a RPM file:
sudo yum install rpm-build
make rpm
# The RPM is generated in rpm/RPMS/x86_64/contextBroker-1.2.0_next-dev.x86_64.rpm
# (version number may vary)
That RPM file is supposed to work in other CentOS 7 systems and you can install just using sudo yum install /path/to/contextBroker-1.2.0_next-dev.x86_64.rpm.

How to install PHP 8.1 on Amazon Linux 2 (ARM64)

I'm trying to install php 8.1 on a Graviton 2 (ARM64) EC2 instance thats running Amazon Linux 2.
All of the guides I've followed use remi-release-7.rpm. When I use this repository, yum updates are flooded with 404 errors like
http://rpms.remirepo.net/enterprise/7/safe/aarch64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
Is there a relatively easy way to install PHP 8.1 on this type of instance?
You can build it from source. I was able to install it on Amazon Linux 2 on Graviton (aarch64, 5.10 kernel) using the steps below. Be sure to update the url in the wget command to the latest available version or what ever you want to build.
sudo yum -y groupinstall "Development Tools" "Development Libraries"
sudo yum -y install libxml2-devel sqlite-devel
wget https://www.php.net/distributions/php-8.1.5.tar.xz
tar -xf php-8.1.5.tar.xz
cd php-8.1.5/
./configure
make -j$(nproc)
sudo make -j$(nproc) install
Alternatively, you could just use a container. You can get one from Amazon ECR here: https://gallery.ecr.aws/docker/library/php
docker pull public.ecr.aws/docker/library/php:8.1-rc-apache-bullseye
Amazon Linux 2 now has built-in support for PHP 8.1 including ARM!

apt-get update in a dockerfile destroys app consistency?

In the dockerfiles I have seen, and the in the best practices for writing a docker file: https://docs.docker.com/engine/reference/builder/#copy, when apt-get is used to install some packages, apt-get update is always run first. I have a concern on this because the app we build in the corresponding docker container would depend on these installed packages, if there is some inconsistency in the newest version of the installed packages, the software we build will not work right any more. Why we do not specify a version of the packages, but use apt-get update instead?
From the man page for apt-get:
update is used to resynchronize the package index files from their
sources. The indexes
of available packages are fetched from the location(s) specified in
/etc/apt/sources.list. For example, when using a Debian archive, this command retrieves
and scans the Packages.gz files, so that information about new and updated packages is
available. An update should always be performed before an upgrade or dist-upgrade.
Please be aware that the overall progress meter will be incorrect as the size of the
package files cannot be known in advance.
You can try running apt-get install without running update on a docker image but you'll probably find that a lot of things will fail to install because the package indexes are out of date.
Once you update the package data, then you can specify a specific version for packages when you run install e.g.
apt update && apt install -y \
git=1:2.7.4-0ubuntu1.4
Example with docker container:
> sudo docker run -it ubuntu:16.04 /bin/bash
# root#513eb786d86d:/# apt install git

installing php-imap on amazon ec2 linux 2

I need to install php-imap on amazon ec2 linux 2 instance.
All the php stuff is inside amzn2extra-lamp-mariadb10.2-php7.2 but php-imap package is missing.
Any advice ?
Thanks
I installed it like this.
I downloaded the php source code of the currently installed version in my Amazon Linux 2
wget http://php.net/get/php-7.2.8.tar.bz2/from/a/mirror
Unpacked it and went into php-7.2.8/ext/imap/
Compiled extension:
phpize
./configure
I got some errors.
Some U8T_CANONICAL stuff so
sudo yum install libc-client-devel
Then libc-client.a not found so created a symlink for it:
cd /usr/lib
sudo ln -s /usr/lib64/libc-client.a
some other imap library error so:
sudo yum install uw-imap-static
I got some other errors so the working configure line was:
./configure --with-kerberos --with-imap-ssl
make
SUCCESS!
cd php-7.2.8/ext/imap/modules
sudo cp imap.so /usr/lib64/php/modules/
Created an ini file to load it:
sudo vi /etc/php.d/30-imap.ini
added to the file this content:
extension=imap
restarted php service (you might need to restart httpd depending on your php installation):
sudo systemctl restart php-fpm
PHPinfo now contains:
imap
IMAP c-Client Version 2007f
SSL Support enabled
Kerberos Support enabled
For those who are facing the U8T_CANONICAL error and can't being able to install the libc-client-devel on Amazon Linux 2 AMI need to do something extra to resolve the U8T_CANONICAL error.
The main problem is that libc-client-devel isn't available so we need to do it in another way.
I found this link while searching for my problem. The solution that is posted here is solid. The following link that i gave is for those who are not being able to install the libc-client-devel will be benifited from the link.
Or you could just copy paste the commands i'm giving below.
1 - sudo yum groupinstall "Development Tools"
2 - sudo amazon-linux-extras install epel
3 - yum install epel-release
4 - sudo yum install libc-client-devel uw-imap-static openssl-devel
5 - sudo ln -s /usr/lib64/libc-client.a /usr/lib
The rest can be followed from respondent.
Again thanks to the person who answered.
Same problem here.
I came from debian/ubuntu and i miss a lot of php packages on aws linux2.
I know it's still a candidate and not a final LTS release. Only worked for a month with this distro and saw a lot of changes and updates. Some php dependencies can be solved with pear or pecl, but I couldn't get nothing working on php-imap.
php-imap depends on libc-client (maybe that's a problem?)
Here is my solution.
Search for the libc-client rpm that correspond to your version and
install manually.
Search for the rpm that corresponds to your php installed version. In my case it was 7.2.5**-2** about 2 weeks ago. (today is
7.2.5**-3** ) and isntall manually
CODE
wget https://dl.iuscommunity.org/pub/ius/stable/CentOS/7/x86_64//php72u-imap-7.2.5-2.ius.centos7.x86_64.rpm -P /tmp
wget http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/l/libc-client-2007f-16.el7.x86_64.rpm -P /tmp
rpm -i /tmp/libc-client-2007f-16.el7.x86_64.rpm
rpm -i /tmp/php72u-imap-7.2.5-2.ius.centos7.x86_64.rpm
If it fails because Failed dependencies:
rpm -ivh /tmp/php72u-imap-7.2.5-2.ius.centos7.x86_64.rpm --nodeps
I dont like this solution, but can't find for now any other solution more stable and easy. It will be a pain with updates....

How to install Docker from the Source code?

I am trying to install docker from the source code downloaded from github.com/docker/docker
I am unable to install it from the source code .
The Makefile present creates a image , but i want to install it in my system.
Can anyone suggest solution ?
I am using UBUNTU 14.04
Well, idk if this works for your linux distro. (looks like it is ubuntu) but i run kali linux and even if we have different commands to use the process is just as same in every linux distro.
first, before we jump on, we need to update our linux repos.(repositories)
sudo apt update
and,
sudo apt-get update
then,
sudo apt install git
[This installs git]
Now we can start cloning git repos. into our system
go to your desired folder/working directory and type:
sudo git clone "link of the git repo. without the commas"
i would better suggest you to just:
sudo apt install docker.io
[To install docker by apt]
it's better to install it via the docker package and update it to the last version. This is the best way to install docker.
