LifeRay: What is Liferay? How to install it?

What is liferay?

With liferay we can create any number of custom sites. We can easily create sections like web content, blog content etc and share between those
sites. We can drag and drop sections to create website parts. So it is easy to use for admin users to add sections and drag to create pages.

“Liferay Portal is an open source enterprise web platform for building business solutions that deliver immediate results and long-term value. Liferay Portal started out as a personal development project in 2000 and was open sourced in 2001.”

Insallation:

Download liferay from: https://www.liferay.com/it/downloads-community

Or by command line:

wget https://releases.liferay.com/portal/7.3.1-ga2/liferay-ce-portal-tomcat-7.3.1-ga2-20200327090859603.tar.gz

Here we are going to install liferay version 7.3

Links:

https://portal.liferay.dev/docs/7-2/deploy/-/knowledge_base/d/installing-product

OR

check the readme file in (after downloading liferay portal)

~/Downloads/liferay-ce-portal-tomcat-7.3.1-ga2-20191111141448326/liferay-ce-portal-7.3.0-ga1/ folder

After that Download and install Java (JDK) 8 (if necessary) in your local environment.

OpenJDK 8

Java 8 is the current Long Term Support version and is still widely supported, though public maintenance ends in January 2019. To install OpenJDK 8, execute the following command:



sudo apt install openjdk-8-jdk

➜ java -version
openjdk version "1.8.0_232"
OpenJDK Runtime Environment (build 1.8.0_232-8u232-b09-0ubuntu1~18.04.1-b09)
OpenJDK 64-Bit Server VM (build 25.232-b09, mixed mode)

Extract the liferay portal .zip file. Copy the folder liferay-ce-portal-7.3.0-ga1 to your home path. And go inside the folder path as shown below:

cd ~/liferay-ce-portal-7.3.0-ga1/tomcat-9.0.17/bin

and do:

Start Tomcat server:

sh startup.sh

Using CATALINA_BASE:   /home/abhi/liferay-ce-portal-7.3.0-ga1/tomcat-9.0.17
Using CATALINA_HOME:   /home/abhi/liferay-ce-portal-7.3.0-ga1/tomcat-9.0.17
Using CATALINA_TMPDIR: /home/abhi/liferay-ce-portal-7.3.0-ga1/tomcat-9.0.17/temp
Using JRE_HOME:        /usr/lib/jvm/java-8-openjdk-amd64
Using CLASSPATH:       /home/abhi/liferay-ce-portal-7.3.0-ga1/tomcat-9.0.17/bin/bootstrap.jar:/home/abhi/liferay-ce-portal-7.3.0-ga1/tomcat-9.0.17/bin/tomcat-juli.jar
Tomcat started.

Restart command for Tomcat server:

sh shutdown.sh && sh startup.sh

Goto http://localhost:8080/

Go with default hypersonic DB if you are in testing environment.


Restart the Tomcat server

sh shutdown.sh && sh startup.sh

and goto http://localhost:8080

If the server is not started properly, you can check the logs here:

cd ~/liferay-ce-portal-7.3.0-ga1/tomcat-9.0.17/logs/ && tail -f catalina.out

I faced the following issue in new 7.3 version with mysql db which I didn’t face with 7.2 version with Hypersonic DB. My mysql db schema is not proper to version 7.3.

Starting Liferay Community Edition Portal 7.3.0 CE GA1 (Athanasius / Build 7300 / January 20, 2020)

You’re presented a Basic Configuration page. Complete the configuration options. Liferay Portal uses an embedded database (HSQL) to make installation fast and easy. This database is not ready for production, so consider configuring a production-ready database (e.g., MySQL) if you plan on doing more than just exploring/testing. Agree to the terms and conditions, create a password, and configure a security question/answer.

You can now use Liferay Portal!

You can check all the projects from Liferay:

https://liferay.dev/projects

Get started from here:

Liferay IDE:
https://liferay.dev/projects/ide

Liferay SDK:

“Liferay Plugin SDK is a development environment allows you to develop plugins for Liferay of all types such as Portlet, Themes, Layout Templates. The Liferay Plugin SDK is based on the Apache Ant tool and it can be integrated with all the common IDEs or used directly from the command line by executing a set of predefined commands (targets, in Ant’s nomenclature). In this tutorial I show how to configure the Plugin SDK in the Eclipse IDE”

Check this link (this doc is for version 6.1) :

https://portal.liferay.dev/docs/6-1/develop/-/knowledge_base/t/installing-the-sdk

LifeRay DXP:

This is the paid version from Liferay. With Liferay DXP you can implement not just static site, but something like today’s frontend fromeworks do (updating the DOM according to framework and spontaneous data change). Also you get the liferay support according to your plan.

A Ruby on Rails Application without models

This blog is a quick walkthrough of creating a Ruby On Rails application without a model.

Find Rails new options from here:
https://gist.github.com/abhilashak/3c0c62fa62b2f7a439c417b68d032575

Find Gemfile options from here:

http://bundler.io/v1.2/gemfile.html

Install Ruby/Rails using rbenv

$ touch .rbenv-gemsets
$ echo project-name > .rbenv-gemsets
$ rbenv gemset active
$ rbenv install 2.5.3
$ gem install bundler
$ rbenv rehash
$ gem install rails -v 5.2.9
$ rbenv rehash
$ rails new my-new-porject --skip-active-record --skip-bundle -v 5.2.9

Add in Gemfile:

ruby “2.5.3”

comment jbuilder, we don’t need it.

# gem 'jbuilder', '~> 2.8’

Move rbenv gems file to new rails app folder

$ mv .rbenv-gemsets my-new-porject

$ touch .ruby-version

$ echo 2.5.3 > .ruby-version

$ gem install bundler

$ bundle

$ ruby -v
ruby 2.5.3p105 (2018-10-18 revision 65156) [x86_64-darwin18]

Start Rails server:

$ rails s

Gemfile add:

# Bootstrap Theme

gem 'bootstrap', '~> 4.3.0’

# Slim template Engine

gem 'slim', '>=4.0.1’

Do Bundle Install

$ bundle

Rename css to scss because we use bootsrap mixins and variables that work with scss files

$ mv app/assets/stylesheets/application.css app/assets/stylesheets/application.scss

Import Bootstrap styles in app/assets/stylesheets/application.scss:

// Custom bootstrap variables must be set or imported *before* bootstrap.
@import "bootstrap";

Then, remove all the *= require and *= require_tree statements from the Sass file. Instead, use @import to import Sass files.

Bootstrap JavaScript depends on jQuery
Add jquery-rails to Gemfile:

gem 'jquery-rails', '~> 4.3.4’

Bootstrap tooltips and popovers depend on popper.js for positioning.
Add Bootstrap dependencies and Bootstrap to your application.js:

//= require jquery3
//= require popper
//= require bootstrap-sprockets

While bootstrap-sprockets provides individual Bootstrap components for ease of debugging, you may alternatively require the concatenated bootstrap for faster compilation:

//= require jquery3
//= require popper
//= require bootstrap

Sass: Individual components

All Bootstrap opponents will be imported by default.
You can also import components explicitly. To start with a full list of modules copy _bootstrap.scss file into your assets as _bootstrap-custom.scss. Then comment out components you do not want from _bootstrap-custom. In the application Sass file, replace @import ‘bootstrap’ with:

@import 'bootstrap-custom';

Your application.css:

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, or any plugin's
 * vendor/assets/stylesheets directory can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the bottom of the
 * compiled file so the styles you add here take precedence over styles defined in any other CSS/SCSS
 * files in this directory. Styles in this file should be added after the last require_* statement.
 * It is generally better to create a new file per style scope.
 *
 */

/*Custom bootstrap variables must be set or imported *before* bootstrap.
  The available variables can be found: 
  https://github.com/twbs/bootstrap-rubygem/blob/master/assets/stylesheets/bootstrap/_variables.scss
*/
@import "bootstrap";

Your application.js File:

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, or any plugin's
// vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file. JavaScript code in this file should be added after the last require_* statement.
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.
//
//= require rails-ujs
//= require turbolinks
//= require_tree .
//= require jquery3
//= require popper
//= require bootstrap-sprockets

You can check sample bootstrap forms here:

Remove cable.js from javascripts # we don’t need this for now

Install Rails 3.1.3 and set up in Linux

Install RVM

If you are not already installed RVM install from here:
https://rvm.beginrescueend.com/rvm/install/

If you already have rvm installed, update it to the latest version.

$ rvm get latest
$ rvm reload
$ rvm -v

Create a Rails 3.1.3 Gemset

Create a default Rails 3.1.3 gemset. It’s advisable to create a new gemset for each application you build. But to get started, create just one new Rails 3.1.3 gemset as your default.

$ rvm ruby-1.9.2-p290@rails313 --create --default

To see a list of the gemsets you have installed:

$ rvm gemset list

And see a list of the gems included with the standard Ruby installation:

$ gem list

$ rvm list gemsets

rvm gemsets

ruby-1.9.2-p290 [ i386 ]
ruby-1.9.2-p290@global [ i386 ]
=> ruby-1.9.2-p290@rails313 [ i386 ]

Make sure you are using the newest version of Rake before you install Rails 3.1.3.

$ gem update rake
$ rake --version

Install Rails

$ gem install rails -v "3.1.3"
