How to install and configure ThreadFix on Ubuntu. While currently ThreadFix supports Ubuntu 12.04 and newer, these instructions were developed and tested against Ubuntu 16.04.

Prerequisites

Audience: IT Professional and/or End User
Difficulty: Intermediate
Time needed: Approximately 60 minutes
Tools required: OpenJDK 11 or OpenJDK 8 or Oracle Java 8, at least Tomcat 7.0.59, MySQL or Microsoft SQL Server

Install Java

ThreadFix 2.7.9 and newer can run on OpenJDK 11 (or Oracle Java 8 / OpenJDK 8, shown in the sections below).

OpenJDK 11

To install, open a Terminal and run the following commands:

sudo apt-get update
sudo apt-get install openjdk-11-jre

If you have multiple JREs installed, run the sudo update-alternatives --config java command and select the version installed above.

OpenJDK 8

To install, open a Terminal and run the following commands:

sudo apt-get update
sudo apt-get install openjdk-8-jre

If you have multiple JREs installed, run the sudo update-alternatives --config java command and select the version installed above.

Oracle Java 8

To deploy versions of ThreadFix 2.6.2.6 and older, you'll need to use Oracle Java 8. To pull the Oracle version, you'll need to add a repository by opening Terminal and running the following commands:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

Select "OK" to proceed through the install, and accept the license terms.

Install and Configure Tomcat 8

ThreadFix requires at least Tomcat 7.0.59, but we recommend the latest version of Tomcat 8.5.

1. Download the latest version of Tomcat 8.5

wget http://mirrors.advancedhosters.com/apache/tomcat/tomcat-8/v8.5.57/bin/apache-tomcat-8.5.57.tar.gz

2. Create a directory to install Tomcat 8, then extract the tar ball there

sudo mkdir /opt/tomcat
sudo tar xvf apache-tomcat-8*tar.gz -C /opt/tomcat --strip-components=1

3. Create a group and user to manage the Tomcat execution.

sudo groupadd tomcat
sudo useradd -s /bin/false -g tomcat -d /opt/tomcat tomcat

Web.xml Update

For compatibility with Tomcat 8.5.43 and newer, make the following update:

Open the <tomcat-deploy>/conf/web.xml file in a text editor with elevated privilege and edit the default servlet as follows:

• OLD

  Code Block
  <servlet> <servlet-name>default</servlet-name> <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class> <init-param> <param-name>debug</param-name> <param-value>0</param-value> </init-param> <init-param> <param-name>listings</param-name> <param-value>false</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>

• NEW

  Code Block

  <servlet> <servlet-name>default</servlet-name> <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class> <init-param> <param-name>debug</param-name> <param-value>0</param-value> </init-param> <init-param> <param-name>listings</param-name> <param-value>false</param-value> </init-param> <init-param> <param-name>fileEncoding</param-name> <param-value>UTF-8</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>

  (Note that the above adds the fileEncoding parameter and sets its value to UTF-8.)

Enable Tomcat Service

If you want tomcat to run as a service that you can have start automatically at boot, the preferred method in Ubuntu 16.04 is using systemd.  Create a file at /etc/systemd/system/tomcat.service with the following content.

# Systemd unit file for tomcat
[Unit]
Description=Apache Tomcat Web Application Container
After=mysql.service network.target
 
[Service]
Type=forking
 
Environment=JAVA_HOME=/usr
Environment=CATALINA_PID=/opt/tomcat/temp/tomcat.pid
Environment=CATALINA_HOME=/opt/tomcat
Environment=CATALINA_BASE=/opt/tomcat
Environment='CATALINA_OPTS=-Xms2G -Xmx8G -server -XX:+UseParallelGC'
Environment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'
 
ExecStart=/opt/tomcat/bin/startup.sh
ExecStop=/bin/kill -15 $MAINPID
 
User=tomcat
Group=tomcat
UMask=0007
RestartSec=10
Restart=always
 
[Install]
WantedBy=multi-user.target

Reload Systemd to load the Tomcat unit file and enable the tomcat.service.

sudo systemctl daemon-reload
sudo systemctl enable tomcat.service

SSL/TLS Implementation

For information on configuring Tomcat to run over SSL/TLS, refer to the following article.

Install and Configure the Database

• To install and configure MySQL, refer to the Ubuntu MySQL Installation and Configuration page.

• To install and configure Microsoft SQL Server, refer to the Windows SQL Server Configuration page.
