The Synthetic Server requires JDK 17 to run services such as Synthetic Scheduler and Synthetic Shepherd.

You need to set the environmental variable JAVA_HOME to the home directory of the JDK.

Python uses pip to install software. For example, pip could be used on some Linux distributions to install flake8, a Python utility used to lint scripts.

If the machine where you're installing the Synthetic Server does not have Internet access, run the following steps to fetch and install flake8:

1. From a machine with internet access and pip installed:

   1. Create a directory for the flake8 library:

       mkdir ~/flake8

   2. Download the flake8 package:

      Python 2

      python -m pip download flake8 -d ~/flake8

      Python 3

      python3 -m pip download flake8 -d ~/flake8

   3. Zip and tar the flake8 package:

      tar cvfz flake8.tgz ~/flake8

   4. flake8.tgz to the $HOME directory of the host machine of the Synthetic Server.

2. From the host of the Synthetic Server that has no internet access, but does have pip installed:

   1. Unzip and extract the flake8.tgz file:

      tar xvfz flake8.tgz ~/flake8

   2. Change to the flake8 directory.

   3. Install the flake8 library with pip with the following command, replacing <version> with the correct version.

      Python 2

      python -m pip install flake8-<version>-py2.py3-none-any.whl -f ./ --no-index

      Python 3

      python3 -m pip install flake8-<version>-py2.py3-none-any.whl -f ./ --no-index

The Synthetic Server requires the libaio library to be on the system. This library facilitates asynchronous I/O operations on the system.

See How to Install libaio for instructions.

Use yum to install the library, such as:

• yum install libaio
• yum install numactl

Install the library RPM from the Fedora website:

• yum install libaio
• yum install numactl

Use apt-get, such as:

• sudo apt-get install libaio1
• sudo apt-get install numactl
