Getting  Canvas LMS Pre-installed

If you want to skip the installation of Canvas LMS and purchase a pre-installed VPS Canvas already installed, or alternatively, have a secure instance of Canvas LMS hosted on your own domain, please contact me by email  (joseph@ripplesoftware) or via contact page for more details.

The full instructions for installing Canvas LMS on your own Ubuntu 18.04 server are below.

Installing Canvas LMS on Ubuntu 18.04

8GB of ram is recommended for a server running Canvas LMS. However, it is possible that you can install and run Canvas LMS on a server with only 4GB or less. This installation was done on a Digital Ocean Ubuntu 18.04 VPS. Be sure to point your domain’s name-servers at your correct cloud host and edit your DNS networking so that your domain is pointed at your server before you begin. You can check using nslookup command as shown below. The result should show the IP of the sever you are setting up.

Check if your domain is being resolved properly

  1. Install required OS Packages shows errors
    E: Package ‘apache’ has no installation candidate
    E: Unable to locate package sqlite-devel
    E: Unable to locate package xmlsec1-openssl
    E: Unable to locate package xmlsec1-devel
    E: Unable to locate package xmlsec1-openssl-devel
    E: Unable to locate package libxslt-devel

    • I have modified the installation of OS packages section to break down into multiple parts. If apt-get still cannot locate a package you should look up each package and find out how to install on your version of Ubuntu. Also it sounds like you are likely using Ubuntu version 20.04 since python-pip is available for Ubuntu 18.04 but not 20.04. These instructions are written for Ubuntu 18.04. I don’t believe that Canvas LMS has been tested or is supported for Ubuntu 20.04.

      • Hi there, I am using Digital Ocean VPS and Ubuntu 18.04. I notices these errors.

        1. after input: sudo sh -c ‘echo deb https://oss-binaries.phusionpassenger.com/apt/passenger xenial main > /etc/apt/sources.list.d/passenger.list’sudo apt-get update

        you get this error: N: Ignoring file ‘passenger.listsudo’ in directory ‘/etc/apt/sources.list.d/’ as it has an invalid filename extension

        2. gem install bcrypt -v ‘3.1.13’ –source ‘https://rubygems.org/‘
        needs to change “‘” to “‘”

        3. when input: touch /home/canvas/.bash_profile
        gets error msg: touch: cannot touch ‘/home/canvas/.bash_profile’: No such file or directory

        4. when input: /etc/.bashrc >> export RAILS_ENV=production
        gets error msg: /etc/.bashrc: command not found

        • Thanks for finding those error and pointing them out to me. I have corrected the code. If you notice any other errors, please let me know!

          • 1. input: chkconfig ntpd on
            error: chkconfig: command not found

            input: systemctl enable ntpd

            Should it be sudo a2enmod ssl??

            3. setsebool -P httpd_can_sendmail 1
            error: setsebool: SELinux is disabled.

            5. apt-get install -y libapache2-mod-passenger

            Some packages could not be installed. This may mean that you have
            requested an impossible situation or if you are using the unstable
            distribution that some required packages have not yet been created
            or been moved out of Incoming.
            The following information may help to resolve the situation:

            The following packages have unmet dependencies:
            libapache2-mod-passenger : Depends: passenger (= 1:6.0.6-1~xenial1) but it is not going to be installed
            E: Unable to correct problems, you have held broken packages.

            fix:

            sudo apt-get install -y dirmngr gnupg
            sudo apt-key adv –keyserver hkp://keyserver.ubuntu.com:80 –recv-keys 561F9B9CAC40B2F7

          • There should have been an update a at the first line, so I modified include that. It will fix most of those errors. Otherwise, I found Canvas to be a brutal installation with so many dependencies. If you want I can provide a VPS instance of Canvas on Ubuntu, but it’s costly.
