How to Install Bastillion Jump Server on CentOS 7

Bastillion is a web-based SSH Terminal emulator. By using this software we can configure a jump server that provides centrally managed administrative access to systems. The software layers TLS/SSL on top of SSH and acts as a bastion host for administration. Bastillion is a freemium software and we can add maximum 6 users and 12 systems without acquiring a subscription.

In this article, we are installing Bastillion Jump Server on CentOS 7. Bastillion is the fork of Keybox and the same steps can be used to install Keybox software on CentOS 7.

Installing Java 9 on CentOS 7:

Bastillion is a Java based web application and it requires OpenJDK / Oracle JDK 1.9 or later.

Oracle JDK 1.9 is available to download at Oracle website.

We are required an Oracle User Account for downloading Oracle JDK 1.9. Therefore, login to Oracle website and download Oracle JDK 1.9 (RPM).

Transfer the downloaded file to bastillion-01.recipes.com using WinSCP.

Connect to bastillion-01.recipes.com using ssh as root user and install Oracle JDK using rpm command.

# rpm -ivh jdk-9.0.4_linux-x64_bin.rpm

Press Ctrl+C to break the process. Because, we will start Bastillion as a service.

Configure Bastillion startup service on CentOS 7 as follows.

# cd
# cp /usr/lib/Bastillion-jetty/jetty/bin/jetty.sh /etc/init.d/bastillion
# echo JETTY_HOME=/usr/lib/Bastillion-jetty/jetty > /etc/default/bastillion
