Introduction

This document will describe the Initial setup of Site Controller on a CentOS linux distribution. 

Prerequisites

You will need to know the IP of the system and to have access via ssh.

Required installation files

  • SiteController installation archive (e.g. SiteController-install-1.3-Astra.tar.gz):  SiteController modules and necessary python libraries 


SiteController is available through official purchase of a license or directly through azeti for development tests / integration tests. Upload the required files to the server, e.g. in /root/download and proceed from there.

Configure the time zone

Core software installation

All the following commands must be done as root. You can add "sudo" to the beginning of all the commands or use "sudo su" in order to be root and continue with the instructions.


Once the system is installed, you will need to do a basic configuration of the system in order to connect to the cloud server. You should have received all the credentials beforehand, contact your provider in case you miss some information.

  1. Install prerequisites for compiling packages

    yum install gmp-devel python-devel



  2. Install Mosquitto

    1. Download the repository config file for your CentOS version from below and copy it to /etc/yum.repos.d/ You’ll now be able to install and keep mosquitto up to date using the normal package management tools.

    2. Install mosquitto "yum install mosquitto" and mosquitto clients "yum install mosquitto-clients"

      [root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# wget http://download.opensuse.org/repositories/home:/oojah:/mqtt/CentOS_CentOS-7/home:oojah:mqtt.repo

  3. Install SiteController (output was truncated)

    [root@localhost SiteController-install]$ ./setup.sh
Checking python version ... Python 2.7.5
WARNING: at least Python version 2.7.9 is required for TLS support
Hint: you could avoid this question by issuing the setup.sh
script with environment variable IGNORE_PYTHON_TLS_ISSUE set to 1:

    IGNORE_PYTHON_TLS_ISSUE=1 ./setup.sh

Press [a] to abort, any other key to continue!
Checking mosquitto version ... 1.4.10 (build date 2016-12-05 08:26:01+0000)

Your entry: > CentOS_Test
Thank you.
Serial name set to CentOS_Test
Changing serial id of SiteController from "" to "CentOS_Test".


/opt/azeti/SiteController/config/SiteController.cfg has been modified.

Hint: to start the SiteController directly after installation
        run the setup script with AUTOSTART_SITECONTROLLER set to 1:

    AUTOSTART_SITECONTROLLER=1 ./setup.sh

Please check the configurations in
"/opt/azeti/SiteController/config".
Adapt them to your needs, then start the controller with
the following line (copy the complete line, there are two
quotes in it):

    "/opt/azeti/SiteController/run_SiteController.py" start

[root@localhost SiteController-install]$
