Install and Set Up on TomCat

Arthor currently runs on n-1-136, which runs CentOS Linux release 7.7.1908 (Core). You can check the version of CentOS with the following command

    cat /etc/centos-release

Check your current version of Java with the following command:

   java -version

On n-1-136 we are running openjdk version "1.8.0_222", OpenJDK Runtime Environment (build 1.8.0_222-b10), and OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode) If Java is not installed, install it using yum

I followed this link to install TomCat on CentOS 7

Open port for Arthor

In order for Arthor to be usable in the browser, the port you wish to run it on must be opened.

How to run standalone Arthor instance

Setting environment variables for TomCat Server

Set the environment variables in the file. Note: Be sure to edit the file in the directory corresponding to the latest version of TomCat. As of December 2019, we are running 9.0.27 on n-1-136.

  vim  /opt/tomcat/apache-tomcat-9.0.27/bin/

Add the line below to the file above, or substitute the path to wherever you currently store the arthor.cfg file

  export ARTHOR_CONFIG=/usr/local/tomcat/arthor.cfg

Here is an example of the arthor.cfg file:

  # Arthor generated config file
  NTHREADS=64 . 

Important parts of the arthor.cfg file

BINDIR is the location of the Arthor command line binaries. These are used to generate the Arthor index files and to perform searches directly on n-1-136. An example of this would be using atdbgrep for substructure search.

DATADIR This is the directory where the Arthor data files live. Location where the index files will be created and loaded from.

STAGEDIR Location where the index files will be built before being moved into the DATADIR.

NTHREADS The number of threads to use for both ATDB and ATFP searches

Set AutomaticIndex to false if you don't want new smiles files added to the data directory to be indexed automatically
