CentOS 7
|
|
=========
|
|
|
|
We're going to be using CentOS 7 on a cloud server for this installation.
|
|
|
|
Prerequisites
|
|
-------------
|
|
|
|
- Port 9000 must be open and accessible from the Internet so that
|
|
GitHub can communicate with the Zuul web service.
|
|
|
|
Login to your environment
|
|
-------------------------
|
|
|
|
Since we'll be using a cloud image for CentOS 7, our login user will
|
|
be ``centos`` which will also be the staging user for installation of
|
|
Zuul and Nodepool.
|
|
|
|
To get started, ssh to your machine as the ``centos`` user.
|
|
|
|
.. code-block:: shell
|
|
|
|
ssh centos@<ip_address>
|
|
|
|
Environment Setup
|
|
-----------------
|
|
|
|
Certain packages needed for Zuul and Nodepool are not available in upstream
|
|
CentOS 7 repositories so additional repositories need to be enabled.
|
|
|
|
The repositories and the packages installed from those are listed below.
|
|
|
|
* ius-release: python35u, python35u-pip, python35u-devel
|
|
* bigtop: zookeeper
|
|
|
|
First, make sure the system packages are up to date, and then install
|
|
some packages which will be required later. Most of Zuul's binary
|
|
dependencies are handled by the bindep program, but a few additional
|
|
dependencies are needed to install bindep, and for other commands
|
|
which we will use in these instructions.
|
|
|
|
.. code-block:: shell
|
|
|
|
sudo yum update -y
|
|
sudo systemctl reboot
|
|
sudo yum install -y https://centos7.iuscommunity.org/ius-release.rpm
|
|
sudo yum install -y git python35u python35u-pip python35u-devel java-1.8.0-openjdk
|
|
sudo alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 10
|
|
sudo alternatives --install /usr/bin/pip3 pip3 /usr/bin/pip3.5 10
|
|
sudo pip3 install python-openstackclient bindep
|
|
|
|
Install Zookeeper
|
|
-----------------
|
|
|
|
Nodepool uses Zookeeper to keep track of information about the
|
|
resources it manages, and it's also how Zuul makes requests to
|
|
Nodepool for nodes.
|
|
|
|
.. code-block:: console
|
|
|
|
sudo bash -c "cat << EOF > /etc/yum.repos.d/bigtop.repo
|
|
[bigtop]
|
|

|
|
sudo yum install -y zookeeper zookeeper-server
|
|
sudo systemctl start zookeeper-server.service
|
|
sudo systemctl status zookeeper-server.service
|

sudo systemctl enable zookeeper-server.service
