Zephyr Production Installation for Linux

Prerequisites

Ensure your deployment can meet the system requirements for Zephyr.
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 - one of the following:
  - OpenJDK 8 (recommended): Installation instructions - here
  - Oracle Version 1.8 Download - here / Installation instructions - here
- MySQL: 8.0.x Series Download - here / Upgrade / Installation instructions - here
- MySQL Connector: Download - here
- Elasticsearch: v. 8.6.2: Download - here / Installation instructions - here
- Zephyr Linux Installer: Download - here

In a nutshell

The procedure to install Zephyr Server on Linux includes the following steps:

Install Java:
- If you want to use OpenJDK (recommended), refer to https://openjdk.java.net/install/ section "JDK 8" for the installation instructions.
- If you want to use Oracle Java JDK 1.8, review the Oracle JDK documentation or documentation for your Linux distribution for Java installation instructions.
Install MySQL 8.0: 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.
Configure MySQL: See the recommended database settings below.
Install Elasticsearch: Zephyr supports Elasticsearch 8.6.2. Elasticsearch must be installed as a separate process. Zephyr Server installations allow you to install this on the same VM as the Zephyr Server application.
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.
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.
Install / Configure Zephyr server: The installer will guide you through the application configuration options necessary for a new installation.
Set ulimit in Linux: Iincrease ulimit on the server to 65535.

The rest of this guide explains these steps in more detail.

Install & configure MySQL

Install MySQL Server according to the instructions for your Linux distribution:
For MySQL 8.0- https://dev.mysql.com/downloads/mysql/8.0.html
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. Refer to these instructions for how to setup MySQL and Systems to adjust for the "LimitNOFILE" setting.

For MySQL 8.0 - https://dev.mysql.com/doc/refman/8.0/en/using-systemd.html

Install & configure Elasticsearch

Elasticsearch is required to be installed as a separate system service. For information on how to install it, see Steps to Install Elasticsearch.

After you install Elasticsearch, start the service and make sure it is running.

Install Zephyr

Make sure you have installed Elasticsearch prior to installing Zephyr.

Ensure the installer file has the proper permissions to be executed:
```
chmod +x zephyr_(Build Number)_linux_setup.sh
```
Launch the setup file with the -c command line option as shown below, and ensure you launch it as sudo or root:
```
 ./zephyr_(Build Number)_linux_setup.sh
```

You will be prompted to continue with the installer.

Starting Installer...
This will install Zephyr X.X on your computer
OK [o, Enter], Cancel [c]

You may be prompted to choose between a new install or an upgrade.
```
Choose type:
Install [1, Enter], Upgrade [2]
```

You will be prompted to confirm your system meets the Zephyr Server Requirements. Please review that your system meets the requirements before proceeding.

You will be prompted to agree to the Zephyr EULA.

License Agreement
D Software End User License Agreement
IMPORTANT - PLEASE READ CAREFULLY:

This End User License Agreement ("Agreement") constitutes a valid and
binding agreement between D Software, INC. (”d software,” ”WE” or ”US”) and

You will then be prompted to enter the path to place the Zephyr home directory.

Select Destination Location
Setup will install Zephyr into the following folder.
To continue click Next. If you would like to select a different folder, click Browse
[/usr/local/zephyr]

You will then be prompted to choose an installation type. For information on how to deploy Data Center, see Set Up Zephyr Data Center.

.
```
Customization
Server Port :
[80]
```
You will then be prompted to choose a Tomcat Server Shutdown Port. We recommend you leave it to the default port.
```
Tomcat Server Shutdown Port:
[8005]
```

You will then be prompted to choose a database system. Use the default MySQL.

Note: If you had just uninstalled. Please wait few minutes for the port to get free and try again.

# ************************************************************

Zephyr installation is now complete and the service should have started. You can choose 'N' when prompted to Launch Zephyr Desktop and connect to Zephyr from your desktop machine.

ZephyrService.sh may or may not start automatically. Please check and start manually if not started.
Done!

Zephyr x.x has now been installed on your computer.

Zephyr Desktop will now be launched automatically.
You can access additional help from the Zephyr installation.

Click Finish to exit setup.

Launch Zephyr Desktop?
Yes [y, Enter], No [n]

To start Zephyr:

cd /usr/local/zephyr/tomcat/bin

./startup.sh

To stop Zephyr:

cd /usr/local/zephyr/tomcat/bin

./shutdown.sh

Set ulimit in Linux

Increase ulimit on the server to 65535:

Stop the Zephyr Service.
As the root user, open the file /etc/security/limits.conf for editing and add these lines at the end:
```
<zephyr_user> soft nofile 65535
<zephyr_user> hard nofile 65535
```
replacing <zephyr_user> with the user used to install Zephyr.

3. Start a new session and then start the Zephyr service.
