Zookeeper set up for Kaa - kaa

I'm trying to set up kaa v0.10.0 on ubuntu 14.04 LTS. To install zookeper I used the following command.
sudo apt-get install zookeeper
But it fails to start when I start the kaa-node service.
But when I install the package zookeeperd (seen in older kaa versions documentation sudo apt-get install zookeeperd), it works fine.
Can anyone please clarify which is the correct zookeeper package for kaa 0.10? - zookeeper or zookeeperd

From few of my experiences in deploying Kaa, I don't think Zookeeper will start automatically after installation, perhaps you can start it manually before starting Kaa-node.

How to install the new "Boost" dependency using the "AzerothCore Bash Dashboard" installation?

I have an AzerothCore Bash Dashboard installed version.
What should I do to install "Boost" as it seems to be required (from the announcement message on Discord dated May 24th 2021) going forward?
Does a simple
sudo apt-get install boost
work? Or since I installed with the bash dashboard issuing a
git pull
followed by a
./acore.sh compiler build
Will take care of installing any missing dependencies?
Or should I run, instead, another time:
./acore.sh install-deps
Thank you
the following worked for me on Ubuntu 20.04 on an AC bash dashboard setup:
sudo apt install libboost-all-dev
and I successfully managed to update my AC version to latest.
Tested both core compile and run.

EPEL & Codeready-builder AWS EC2 RHEL8

I am running an EC2 instance with a RHEL8 AMI.
I am looking to install R on the instance and I believe I need the EPEL package and to enable the codeready builder through the following two commands
sudo dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf config-manager --set-enabled rhui-codeready-builder-for-rhel-8-rhui-rpms
more info at (https://aws.amazon.com/premiumsupport/knowledge-center/ec2-enable-epel/)
I can download epel (first line) fine but when I run the second line I get the following:
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Error: No matching repo to modify: rhui-codeready-builder-for-rhel-8-rhui-rpms.
Also when I try to run the following, I get the following:
This system has no repositories available through subscriptions.
and for completeness, this is the error when i try to install R
$sudo yum install -y R
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

Error:
Problem: package R-3.6.3-1.el8.x86_64 requires R-devel = 3.6.3-1.el8, but none of the providers can be installed
- package R-devel-3.6.3-1.el8.x86_64 requires R-core-devel = 3.6.3-1.el8, but none of the providers can be installed

- nothing provides texinfo-tex needed by R-core-devel-3.6.3-1.el8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
Does anyone have any ideas or has solved this same problem?
I worked this out just after writing it...
For anyones reference, it seems AWS had their command written wrongly.
Still download epel package as shown above
sudo dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
and instead of the following from AWS website
sudo dnf config-manager --set-enabled rhui-codeready-builder-for-rhel-8-rhui-rpms
You can use
sudo dnf config-manager --set-enabled codeready-builder-for-rhel-8-rhui-rpms
Then go ahead with sudo yum install -y R

unable to install DPDK in Devstack(in Ubuntu 16.04 version)

I am trying to install Devstack with DPDK in Ubuntu 16.04. I have installed Devstack (Rocky version) in Ubuntu machine.
Reference link to install the devstack is mentioned below.
https://docs.openstack.org/devstack/latest/
Devstack was successfully installed. However, i am trying to validate DPDK in it.
When i check the status of both DPDK and openvswitch. It is showing the status of openvswitch alone.
Can anyone, please let me know how to install dpdk manually or along with Devstack?
I haven't tried devstack with ovs-dpdk, but if you are using ovs which is compiled with dpdk, then you can start from 'setup Hugepage' section in following doc manually:
http://docs.openvswitch.org/en/latest/intro/install/dpdk/
I also notice networking-ovs-dpdk plugin which can be used in devstack.

Install kaa single-node 0.10.0 or 0.11.0 on Ubuntu 18.10

is Kaa single-node compatible with Ubuntu 18.10?
If i install on Ubuntu 16.04 it works, on Ubuntu 18.10 everything seems starting right but when i try connecting to http://localhost:8080/kaaAdmin it shows that "it couldn't connect to the page" (in Ubuntu 16.04 works). Is it a firewall problem?
I followed kaa installation guide (configuring zookeeper, mongodb etc)
Kaa's logs are empty (no errors, no warnings)...
I also tried compiling kaa 0.11.0 from source and this situation persists.
Greetigs,
kaa_newbie.
EDIT: It's a Zookeeper problem! Kaa works only on Zookeeper v3.4.8. If I install this version on Ubuntu 18.10, it works!

How to install a specific version of nginx on Debian 7?

I did the following to nstall nginx on Debian 7
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install nginx
sudo service nginx start
This installed the latest version of nginx , How do I install another version?
Doing sudo apt-get install nginx=1.2 or sudo apt-get install nginx-1.2 does not work. It fails saying version not found?
Older version of Nginx is not available in Debian repository, you need configure Nginx Debian repository http://nginx.org/en/linux_packages.html or find the deb package and install manually.
A distribution of Debian is a set of software packages that was tested to run well together. Every change imposes a risk to break somethign somewhere since that change may not have been prepared for by another software also installed.
When you are for a newever version than what the distributions ships, then a look at the package "tracker" will present an overview of what is currently available, which includes so-called backports to your distribution: https://packages.qa.debian.org/n/nginx.html but indeed the packages directly provided by nginx.org should be just fine. For looks into the past, check out http://snapshot.debian.org/package/nginx/ .
