Installing the EMF on Linux
The following instructions are for CentOS 7. For other Linux distributions, you'll need to use the appropriate package manager commands (yum, dnf, apt).
sudo yum install java-1.8.0-openjdk
sudo yum install postgresql-server
sudo postgresql-setup initdb
sudo systemctl start postgresql
sudo systemctl enable postgresql
Enable password authentication for database connections. Change ident to md5.
sudo vi /var/lib/pgsql/data/pg_hba.conf
# IPv4 local connections:
host all all 127.0.0.1/32 md5
sudo systemctl reload postgresql

Visit https://cmascenter.org/cost/ and download the latest version of CoST/EMF. On the downloads page, look for the file labeled "CoST/EMF Windows Installation (Zip file)".

sudo systemctl stop tomcat
sudo cp state_install/EMF_Server/emf_v3.2.war /opt/tomcat/webapps/emf.war
sudo cp state_install/postgresql/postgresql-9.4-1201.jdbc41.jar /opt/tomcat/lib
sudo systemctl start tomcat
cd state_install/EMF_Client
./EMFClient.sh
The EMF Client is a Java program that can be run on Windows, macOS, or Linux. Java 8 must be installed on any computer that will run the EMF Client. To install the client, copy the state_install/EMF_Client directory to the computer.
On Windows, edit the file EMFClient.bat and update the following lines to match where the EMF Client is located (EMF_HOME) and the path to where Java is installed (JAVA_EXE). For the TOMCAT_SERVER setting, replace localhost with the IP address of the Linux machine running the EMF Server.
set EMF_HOME="C:\Users\Public\EMF"
set JAVA_EXE=C:\Program Files\Java\jre1.8.0_161\bin\java
set TOMCAT_SERVER=http://localhost:8080
On Linux or macOS, edit the file EMFClient.sh and update the TOMCAT_SERVER setting with the IP address of the Linux machine running the EMF Server.
export TOMCAT_SERVER=http://localhost:8080
