RPM-based installation

The following instructions are meant to be "copy-and-paste" to install and demonstrate. If a step requires you to think and make a decision, it will be prefaced with ⚠️.

The instructions have been tested against a bare CentOS-7-x86_64-Minimal-1511.iso image.

Overview

1. Install prerequisites
2. Set environment variables
3. Clone repository
4. Install

Prerequisites

1. YUM installs

   sudo yum -y install epel-release
   sudo yum -y install git

Set Environment variables

1. ⚠️ Set environment variables. These variables may be modified, but do not need to be modified. The variables are used throughout the installation procedure.

   export GIT_ACCOUNT=senzing
   export GIT_REPOSITORY=stream-logger
   export SENZING_DIR=/opt/senzing

2. Synthesize environment variables.

   export GIT_ACCOUNT_DIR=~/${GIT_ACCOUNT}.git
   export GIT_REPOSITORY_DIR="${GIT_ACCOUNT_DIR}/${GIT_REPOSITORY}"
   export GIT_REPOSITORY_URL="https://github.com/${GIT_ACCOUNT}/${GIT_REPOSITORY}.git"
   export LD_LIBRARY_PATH=${SENZING_DIR}/g2/lib:$LD_LIBRARY_PATH
   export PYTHONPATH=${SENZING_DIR}/g2/python

Clone repository

1. Get repository.

   mkdir --parents ${GIT_ACCOUNT_DIR}
   cd  ${GIT_ACCOUNT_DIR}
   git clone ${GIT_REPOSITORY_URL}
