I am testing the Orion Context Broker, using orion-psb-R3.4.
I’ve read http://forge.fi-ware.org/plugins/mediawiki/wiki/fiware/index.php/Publish/Subscribe_Broker_-_Orion_Context_Broker_-_Installation_and_Administration_Guide#Optional_packages
Where can we find the contextBroker-test package?
I want to use the accumulator-server.py
accumulator-server.py is part of the contextBroker-tests package, that you can install doing the following:
Add FIWARE yum repository to your system (see this link)
Install using the following command:
yum install contextBroker-tests
Once installed, the accumualtor-server.py is exactlty in the following path:
/usr/share/contextBroker/tests/accumulator-server.py
It is recommented to create a symlink from /usr/local/bin to that file to have it at hand.

I am currently working on using grpc-web to write a simple client for my service. I have created a service.proto file which was successfully compiled using protoc. The problem arose when I tried to generate the gRPC-Web service client stub using the plugin protoc-gen-grpc-web which doesnt work despite having installed the latter.
Got the following error :
protoc -I=./ service.proto --grpc-web_out=import_style=commonjs,mode=grpcwebtext:./
protoc-gen-grpc-web: program not found or is not executable
--grpc-web_out: protoc-gen-grpc-web: Plugin failed with status code 1.
Any suggestions on how to solve this issue? Thank you!
You'll need to make the protoc-gen-grpc-web plugin executable and move it to a directory that is discoverable from your PATH environment variable.
From grpc-web/README:
For example, in MacOS, you can do:
$ sudo mv ~/Downloads/protoc-gen-grpc-web-1.2.1-darwin-x86_64 \
/usr/local/bin/protoc-gen-grpc-web
$ chmod +x /usr/local/bin/protoc-gen-grpc-web
You don't even have to install the plugin globally and make it discoverable from your PATH:
protoc accepts --plugin arguments to point to a required plugin. For protoc-gen-grpc-web (as for many others) there's even npm support, so you can get it with npm i --save-dev protoc-gen-grpc-web and then run protoc with --plugin=protoc-gen-grpc-web=./node_modules/.bin/protoc-gen-grpc-web
I'm using MacOS. You need to install this first with brew
$ brew install protoc-gen-grpc-web
The best solution that I could use for Linux based system was globally installing protoc-gen-grpc-web. This directly takes the files from the /bin of the node_modules files created globally across your system
sudo npm install -g protoc-gen-grpc-web
I am trying to install kafka on on centOS using this page .
https://docs.confluent.io/current/installation/installing_cp/rhel-centos.html
but getting this error
No package confluent-community-2.11 available.
After running this page command
sudo yum clean all && sudo yum install confluent-community-2.11
It seem no rpm is given here: https://packages.confluent.io/rpm/5.1/7
You need both repos added to yum, not just the 5.1/7 (which has some specific additional packages, not the main confluent-community-2.11 package)
I am trying to install mongodb 4 into an amazonlinux:2018.03 docker container. I followed these instructions. I managed to install only one package: mongodb-org, but I failed to install the rest of it: mongos, server, shell, tools.
The error I am give is the following:
Error: Package: mongodb-org-mongos-4.0.2-1.amzn2.x86_64
(mongodb-org-4.0)
Requires: libc.so.6(GLIBC_2.18)(64bit)
There is a libc.so.6 in /lib64 pointing to /lib64/libc-2.17.so
Any help would be appreciated. Thank you.
It looks like you're using an AmazonLinux 2 MongoDB package within an AmazonLinux 1 container. You should try using the MongoDB 4.0.2 package for AmazonLinux 1.
Cloud9 runs on the old Amazon linux instance, so you may run into this problem using the IDE. This is how I got it working for myself on Cloud9 running in an Amazon Linux instance:
File named "mongodb-org-4.2.repo"
[mongodb-org-4.2]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/amazon/2013.03/mongodb-org/4.2/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.2.asc
Then I ran the following in the same directory as that file:
sudo cp ./mongodb-org-4.2.repo /etc/yum.repos.d/mongodb-org-4.2.repo
sudo yum install -y mongodb-org
I had a similar issue but I followed this installation guide here; https://www.attosol.com/how-to-install-mongodb-in-aws-linux-step-by-step
You can get a more appropriate repo on this link https://www.mongodb.org/dl/linux/x86_64-amazon . My suggestion is that you experiment with the two most recent ones and see what works.
I'm trying to install RabbitMQ 3.7.4 on CentOS 6.8. Currently I have installed Erlang 20 following instruction from https://github.com/erlang/otp/blob/maint/HOWTO/INSTALL.md , but when I tried :
sudo yum install https://dl.bintray.com/rabbitmq/all/rabbitmq-server/3.7.4/rabbitmq-server-3.7.4-1.el6.noarch.rpm
it doesn't detect the Erlang 20. Instead it searched for the available Erlang package from my EPEL, which is the R14B, and wont install since it is lower than the minimum Erlang version requirements. How do I fix this and install RabbitMQ?
From the Installation instructions at https://packages.erlang-solutions.com/erlang/
Installation using repository
1. Adding repository entry
To add Erlang Solutions repository (including our public key for verifying signed package) to your system, call the following commands:
wget https://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
Alternatively: adding the repository entry manually
RPM packages are signed. To add Erlang Solutions key, execute command:
rpm --import https://packages.erlang-solutions.com/rpm/erlang_solutions.asc
Add the following lines to some file in "/etc/yum.repos.d/":
[erlang-solutions]
name=CentOS $releasever - $basearch - Erlang Solutions
baseurl=https://packages.erlang-solutions.com/rpm/centos/$releasever/$basearch
gpgcheck=1
gpgkey=https://packages.erlang-solutions.com/rpm/erlang_solutions.asc
enabled=1
2. Adding repository with dependencies
Packages requires some packages that are not present in standard repository. Please ensure that EPEL respository is enabled.
3. Installing Erlang
Call the following command to install the "erlang" package:
sudo yum install erlang
or this command to install the "esl-erlang" package:
sudo yum install esl-erlang
Please refer to the FAQ for the difference between those versions. Your erlang will be kept up to date either way.
How I yum install postgres using rpm from http://yum.postgresql.org?
I followed these steps:
Install Centos 6.5 from Live DVD:
http://vault.centos.org/6.5/isos/x86_64
I google: Postgres 9.5 install on Centos 6.5
I run two shell commands:
wget https://download.postgresql.org/pub/repos/yum/9.5/redhat/rhel-6-x86_64/pgdg-centos95-9.5-2.noarch.rpm
yum install pgdg-centos95-9.5-2.noarch.rpm
I'm not sure what to do next.
I see this page:
http://yum.postgresql.org/repopackages.php
At the top of the page is a link: 'Yum Howto'
I click that link and see this page:
http://yum.postgresql.org/howtoyum.php
The first link there is this:
http://yum.postgresql.org/repopackages.php
So I am seeing circular documentation rather than helpful documentation.
I see a link to a pdf:
http://yum.postgresql.org/files/PostgreSQL-RPM-Installation-PGDG.pdf
I open the pdf and it lists packages that are available.
I surmise that I need these packages:
postgresql-libs, postgresql and postgresql-server
It does not say where they are.
Questions:
Where are the packages listed in PostgreSQL-RPM-Installation-PGDG.pdf ?
Assuming I want to install: postgresql-libs, postgresql and postgresql-server, How to?
At postgresql.org, I see this rpm : pgdg-centos95-9.5-2.noarch.rpm
What is the purpose of pgdg-centos95-9.5-2.noarch.rpm?
I figured this out.
The purpose of pgdg-centos95-9.5-2.noarch.rpm is to expose more packages to the yum-package-list on my host.
I can then see some of them with this command:
yum list postgresql95*
And I can install them with this command:
yum install postgresql95 postgresql95-server postgresql95-libs postgresql95-devel
I ran the above commands on my centos host and they worked perfectly.
