Install open source flat-file CMS Grav on Ubuntu

Grav is open source flat-file CMS which means without any needs of the database.  It only has two requirements web server like Apache, Nginx, IIS, etc … and PHP 5.6.3 or higher.  It uses Markdown for formatting syntax and it automatically converts to HTML.  It also has a Normal or Expert mode for editing content.  I am installing this on Ubuntu 16.04, but it should work just fine with other versions of Ubuntu as long as you meet the server/PHP requirement.  Also, Grav have two options when you download Grav core or Grav Core + admin plugin, I am using installing with Admin plugin to get more options.

Installation is very easy, once you have the web server of your choice and PHP version meets the requirement.

Download the Grav from https://getgrav.org/downloads and extract it then upload it to your web server

Then just go to your Domain URL and you should see the following screen, where you fill in your admin information and click Create User

If everything goes well it should bring you to Dashboard screen, this is your admin screen, where you will be able to add, delete, and make changes to your Grav CMS.  Also before you do anything click Backup and it will automatically back up for you.

This is default home page of Grav after fresh installation

If you want to edit your page to your Grav CMS login to admin (YourDomain/admin)
To edit Home Page, click on Pages>click Home

Now you should be to edit Content and click on the other tabs to see more options, Advance and Mode type Normal/Expert.

After the installing you may need to upgrade, just click on the Update on your dashboard and click continue

Back to your dashboard you should see fully updated, otherwise click check for updates

That’s it, enjoy it



osTicket installation on Ubuntu 16.04

osTicket is one of the great open source support system, very easy to install and use.  I have noted the whole process, short version, and detailed version.  What you will need from start to finish.  This installation is fresh, without any add-ons or any customization osTicket version 1.10.1.  I have written this installation based on Ubuntu 16.04 with Apache as a web server, it may work just fine with other versions of Ubuntu servers or similar to other flavors of Linux systems.  Assuming you have your web server and domain up and running without any issues.  So, let’s get started

What you will need

    • PHP 5.6 (or better I am going to be using PHP7.0)
    • MySQL 5.0 (or better)
    • 2GB memory recommended 4GB or more
  • Access to web/database server via SSH
  • Access to site file via (FTP, SFT, GUI, SSH, etc. …)

Getting server ready to install osTicket:

Click Continue once you have fixed any issues, please correct it before going forward

Setup osTicket Database and give full permission using whichever tool you are comfortable with it, then fill in details and click Install now

if everything went well you should see Congratulation, then just change the permission of your config file

You should be able to login to your osTicket support system with the information you used earlier, see my notes, where I have put in some common issues you may encounter when installing.

Notes and common errors/solution: 

You may need to do these if you get errors or other settings changes


If you have not copied the ost-sampleconfig.php to include/ost-config.php
then you will get the following message


You will also need to make sure that ost-config.php has correct permission, otherwise, you will get this message:


if you have already installed the PHP IMAP extension and still gives you an error, take a look at your php.ini file and enable it by uncommenting /etc/php/php.ini:
;extension=imap.so
to
extension=imap.so


You may need to restart the web service after making changes to take effect:
sudo systemctl restart apache2

$this->data = new SessionData([‘session_id’ => $id]);
