CentOS Enterprise Setup

You will learn

How to install and configure ThreadFix on CentOS. While these instructions should apply to RHEL as well, the following instructions were developed and tested against CentOS 7.

Prerequisites

Audience: IT Professional and/or End User
Difficulty: Intermediate
Time needed: Approximately 60 minutes
Tools required: OpenJDK 8, latest version of OpenJDK 11 or Oracle Java 8, latest version of Tomcat 8.5, MySQL or Microsoft SQL Server

Install Java

To check the currently-installed version, run the java -version command.

OpenJDK 11

ThreadFix version 2.7.9 and newer can run on OpenJDK 11 (version 11.0.5 or newer), OpenJDK 8, or Oracle Java 8, shown in the sections below. If you don't have OpenJDK 11 installed, you can install it by running the following command:

sudo yum install java-11-openjdk

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

OpenJDK 8

ThreadFix version 2.7 and newer can run on OpenJDK 8 or Oracle Java 8, shown in the next section. If you don't have OpenJDK 8 installed, you can install it by running the following command:

sudo yum install java-1.8.0-openjdk

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

Oracle Java 8

To deploy versions of ThreadFix 2.6.2.6 and older, visit the Oracle JDK download page here and look for the .rpm version of the Linux x64 distribution. Copy the download link and wget it.
Example wget command to download the jdk-8u192-linux-x64.rpm file:

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "https://download.oracle.com/otn-pub/java/jdk/8u192-b12/750e1c8617c5452694857ad95c3ee230/jdk-8u192-linux-x64.rpm"

Install with yum localinstall.

Example using the file downloaded above:

The JDK should be installed at /usr/java/<jdk-version> (e.g., /usr/java/jdk1.8.0_192). You can verify the install using the java -version command. If you have multiple JDKs installed, run the sudo alternatives --config java command and select the version installed above.

Install and Configure Tomcat 8.5

ThreadFix recommends the latest version of Tomcat 8.5. Note versions prior to 8.5.78 are not recommended due to security exploit CVE-2022-22965.

  1. Download the latest version of Tomcat 8.5.

For the current version of ThreadFix, yum is not recommended for installing Tomcat. Getting the latest version of Tomcat 8.5 directly with wget is the preferred method. The link to the tarball is provided by the official Apache Tomcat site and it is a mirror site hosting the most recent version.

If the above command doesn't work, the download may have been moved/updated. Browse to Apache Download Mirrors  to determine the most recent version available.

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


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

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

  • NEW

(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 is using systemd.  Create a file at /etc/systemd/system/tomcat.service with the following content. CentOS systemd 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

Install and Configure ThreadFix
