Installing Manifold on Centos/RHEL: Download & Install Package

Note: Manifold is a new piece of software, and we're working hard to refine and improve the installation process. If you run into problems, please don't get frustrated. Let us know in Slack (join here) or report the issue here. It's very important to us that Manifold be easy to install, and we appreciate your help as we improve this process.

The most recent Manifold CentOS release is 5.1.3. To install previous releases, grab the apprporiate URL from the downloads page.

The following instructions have only been tested on CentOS 7, but we expect this RPM to work just fine on RHEL7.

Installation Prerequisites

  1. Manifold should be installed on a virtual or physical server with at least 1 CPU and 6 GB of RAM (8GB preferred).1 We’ve had good luck installing Manifold on Google Cloud Compute instances, AWS EC2 instances, and Digital Ocean droplets.

  2. You will need to have root access to the server and the ability to shell into the server.

  3. Your server should have a fully qualified domain name (FQDN). If the hostname is setup correctly, the installer should detect it and configure manifold accordingly. If it’s not, you can set the hostname manually in /etc/manifold/manifold.rb and reconfigure the application. Reconfiguration is discussed below.

Installation Process

via YUM Repository

1. Select and add a repository

Manifold offers two tracks to receive packages from, release and devel.

For production-ready, official releases, add the following yum repository as root (or via sudo). Most people will choose this one.

curl -O /etc/yum.repos.d/manifold-release.repo

To include official release candidates along with official releases, you can add the following instead:

curl -O /etc/yum.repos.d/manifold-devel.repo

Note: You should not add both tracks.

2. Install the package

Once the correct repository is in place:

yum install manifold

via Manual RPM

1. Download the Package

Shell into the server as root and download the most recent package.

cd ~
curl -O

2. Install the Package

Install the RPM package.

cd ~
rpm -ivh manifold-5.1.3-1.el7.x86_64.rpm

Apply Minimal Configuration

The package installer creates a file at /etc/manifold/manifold.rb. Use this file to configure and manage the various services that Manifold is composed of. After changing this file, you’ll need to run sudo manifold-ctl reconfigure from the command line so that Manifold picks up the changes and regenerates various configuration files based on the new settings.

For now, let’s just make sure Manifold is on the right domain. Open /etc/manifold/manifold.rb in your preferred text editor (nano, vi, etc.) and look for the external_url setting near the top of the file. Set this to the fully qualified domain name of your Manifold installation, then reconfigure Manifold with the following command. You may be prompted to accept the license. You can scroll through the licenses by pressing space, or “q” to exit the license view. You will need to accept the licenses before proceeding with the installation.

/usr/local/bin/manifold-ctl reconfigure

Once this process is complete, visit the fully qualified domain name in your browser. You should see an empty Manifold home page.

If everything looks good, proceed to the next step.


1 We advise against attempting to install Manifold in a shared hosting environment for security and stability reasons. Manifold consists of a number of distinct services, each of which requires RAM to function correctly. On a small VM with less than 6GB of RAM, you will likely need to enable swap memory or risk consuming all available memory.
