• Click Run in wizard window to run installation script
• When prompted, press Return to close the window
• Devices>Shard Folders>Shared Folder Settings
• Click the "Add a folder" icon and select a path to the folder you want to share between your Host and your Virtual Machine. Select "Auto-mount" and "Make Permanent" and click "OK". Then Click "OK" on the next window
• The "sf_Desktop" drive should be visible on your Virtual Machine desktop
• Select Devices>Shared Clipboard>Bidirectional (preference, not requirement)

Step 3 : Install Oracle Java SE Development Kit 8u202

This will require registering as a user with Oracle. It's free.

• Open FireFox and copy this link into the address bar to navigate to Oracle's download page.
  https://www.oracle.com/java/technologies/javase/javase8-archive-downloads.html

• Download the jdk-8u202-linux-x64.rpm

• you will need to be logged in as root or use sudo to install java

• move it to the /opt directory by opening Terminal (right click on desktop) and running
  mv ~/Downloads/jdk-8u202-linux-x64.rpm /opt

• Go to /opt directory
  cd /opt/

• Run local install command
  yum localinstall jdk-8u202-linux-x64.rpm

• Type "y" when prompted in the installation wizard

• Run alternatives command
  alternatives --config java

• Select the correct number option for 8u202

• Check version by running the command
  java -version

Step 4: Install Apache Maven

• In the terminal, use the wget command to download Apache Maven
  wget https://us.mirrors.quenda.co/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz
• Expand and install
  tar -xzvf apache-maven-3.6.3-bin.tar.gz
• Give ownership to the user
  chown -R root:root /opt/apache-maven-3.6.3/
• Add Maven to your paths
  echo 'export PATH=$PATH:/opt/apache-maven-3.6.3/bin' | sudo tee -a /etc/profile
• Refresh profile to enforce changes
  cd /etc/
. profile
• Change working directory back to /opt and check version to confirm installation and
  cd /opt/
mvn -version
• Check paths to ensure /opt/apache-maven-3.6.3/bin is there
  echo $PATH

Step 5: Install Apache ActiveMQ

• In the terminal, use the wget command to download Apache ActiveMQ
  wget http://archive.apache.org/dist/activemq/5.16.0/apache-activemq-5.16.0-bin.tar.gz
• Expand and install
  tar -xzvf apache-activemq-5.16.0-bin.tar.gz
• Start ActiveMQ
  ./apache-activemq-5.16.0/bin/activemq start
• Confirm installation and status by viewing in web browser
  http://localhost:8161/admin

user: admin
password: admin

Step 6: Install Apache Tomcat

• In the terminal, use the wget command to download Apache Tomcat
  wget http://archive.apache.org/dist/tomcat/tomcat-9/v9.0.37/bin/apache-tomcat-9.0.37.tar.gz
• Expand and install
  tar -xzvf apache-tomcat-9.0.37.tar.gz

Step 7: Install MariaDB Client and Server

• update yum repositories
  sudo yum -y update
• modify MariaDB repo to select correct versions for GTAS use
  sudo tee /etc/yum.repos.d/MariaDB.repo<<EOF
• Copy and paste all of this text into the document editor and press "return"

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.4/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
EOF

• Update the cache
  sudo yum makecache fast
• Download and install MariaDB server and client software
  sudo yum -y install MariaDB-server MariaDB-client
• Enable MariaDB as a service
  sudo systemctl enable --now mariadb
• Configure MariaDB installation
  sudo mysql_secure_installation
• Follow the prompts. Configure to suit your preferences

Step 8: Install GTAS from Source Code on GitHub

• Download the source code
  git clone --branch dev --single-branch https://github.com/US-CBP/GTAS.git

• To create the GTAS database, navigate to gtas-commons
  cd GTAS/gtas-parent/gtas-commons/

• Run the following command
  mvn clean install

• Run each of these commands sequentially, after the previous is successful
  mvn hibernate:update
mvn hibernate:drop
mvn hibernate:create

• check for creation of database and table population
  mysql -u root -p

• enter password from MaraiDB configuration

• Select GTAS database
  use gtas;

• check tables
  show tables;

• check user table
  select * from user;

• To compile .war files from source code, navigate to the gtas-parent directory
  cd /opt/GTAS/gtas-parent/

• Run clean install command
  mvn clean install

• Copy .war files and application.configuration file to the tomcat server
  cp /opt/GTAS/gtas-parent/gtas-job-scheduler-war/target/gtas-job-scheduler.war /opt/apache-tomcat-9.0.37/webapps/
cp /opt/GTAS/gtas-parent/gtas-webapp/target/gtas.war /opt/apache-tomcat-9.0.37/webapps/
cp /opt/GTAS/gtas-parent/gtas-commons/src/main/resources/default.application.properties /opt/apache-tomcat-9.0.37/conf/application.properties

• Create directories for messages. The best place for them is in the Host/Virutal Machine shared directory
  mkdir /media/sf_Desktop/in
mkdir /media/sf_Desktop/working
mkdir /media/sf_Desktop/out
mkdir /media/sf_Desktop/error

• Change the directory addresses in "application.properties" for the file loader to match the directories made
  vim /opt/apache-tomcat-9.0.37/conf/application.properties

press "i" to insert
make required edits to the doc
press "esc" to stop
press ":" to enter prompt
type "wq" and press "enter" to write and quit

• change the directory addresses for the file loader to match the directories made (i.e. message.dir.origin=/media/sf_Desktop/in )

message.dir.origin=/media/sf_Desktop/in
message.dir.working=/media/sf_Desktop/working
message.dir.processed=/media/sf_Desktop/out
message.dir.error=/media/sf_Desktop/error

• To start the server, enter the command
  /opt/apache-tomcat-9.0.37/bin/catalina.sh run
• You can now access the GTAS webapp by opening a browser and navigating to:
  http://localhost:8080/gtas/login.html
  username: admin
  password: password

Step 9 Optional: Forward ports to access GTAS on Host Machine

• In the CentOS user interface, in the menu bar, go to firewall settings: Applications>Sundry>Firewall

• configuration permanent add 8080

• configuration runtime add 8080

• on Oracle VM VirtualBox Manager go to the menu bar on the Host Machine: Network>Advanced>Port Forwarding

• Add a rule

Name: webapp
Protocol: TCP
Host IP: 127.0.0.1
Host Port: 8080
Guest IP: 10.0.2.15
Guest Port: 8080

• Access the web application on your host machine at the address:
  http://127.0.0.1:8080/gtas/login.html
  username: admin
  password: password
