Linux Installation Steps


Prerequisites

  • Ensure your deployment can meet the system requirements for Zephyr.

Zephyr Server System Requirements 

Zephyr Data Center System Requirements

Zephyr Cloud Deployment 

Zephyr Server Sizing & Utilization  

  • Ensure you have your Zephyr license and any plugin license files that were provided. 

  • Download and install or upgrade the required software dependencies: 
    • JAVA JDK: Oracle Version 1.8 Download - here /  Installation Instructions - here

    • MySQL: 5.6.x Series only Download - here /  Upgrade / Installation Instructions - here

    • MySQL Connector: Download - here

    • Elasticsearch (5.5.0 only): Download - here /  Installation Instructions - here

    • Zephyr Linux Installer: Download - here

Install Software Dependencies

The following software will need to be installed:

  1. Install Oracle JAVA JDK 1.8: Please review the Oracle website or documentation for your Linux distribution for JAVA installation instructions.  

  2. Install MySQL 5.6:  A database server is required to use Zephyr, and MySQL is the default for single server installations. If you plan to use MS SQL or Oracle, please review our Zephyr Data Center installation instructions.

  3. Configure MySQL:  See the recommended database settings below.

  4. Install Elasticsearch 5.5.0:  It is now a requirement to install Elasticsearch as a separate process. Zephyr Server installations allow you to install this on the same VM as the Zephyr server application. 

  5. Upload Zephyr License: The Zephyr installer requires access to the license file provided. It will need to be first uploaded to the file system of the server

  6. Upload the MySQL Connector: The Zephyr installer requires access to the MySQL connector jar file downloaded. It will need to be first uploaded to the file system of the server.

  7. Install / Configure Zephyr server: The installer will guide you through the application configuration options necessary for a new installation.

  8. Setting ulimit in Linux: Increase ulimit on the server to 65535

Install & Configuring MySQL

  1. Install MySQL Server according to the instructions for your Linux distribution: https://dev.mysql.com/downloads/mysql/5.6.html

  2. Configure MySQL with the following settings below and after configuration, restart the MySQL service. You will need to edit the my.cnf file and add the following configuration settings.  Depending on your linux distribution, this may be in the /etc folder. 

[mysqld]
user=mysql
max_allowed_packet = 150M
max_connections = 600
default-storage-engine=INNODB
character-set-server=utf8
collation-server=utf8_unicode_ci
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

[mysqld_safe]
default-storage-engine=INNODB
character-set-server=utf8
collation-server=utf8_unicode_ci

[mysql]
max_allowed_packet = 150M

[mysqldump]
quick
max_allowed_packet = 150M


NOTE: You may run into an issue where the "max_connections" setting does not actually reflect in MySQL. This could be due to a file open limit built into the Linux operating system. Please see these instructions for how to setup MySQL and Systems to adjust for the "LimitNOFILE" setting.  https://dev.mysql.com/doc/refman/5.7/en/using-systemd.html



Install & Configure Elasticsearch

Elasticsearch is required to be installed as a separate system service. 

  1. Download Elasticsearch 5.5.0: https://www.elastic.co/downloads/past-releases
