Install Cinelerra Video Editor on Ubuntu 24.04 | 22.04

Last updated: April 21, 2024

This tutorial shows how to install Cinelerra video editor in current Ubuntu 22.04 and Ubuntu 24.04.

Cinelerra is a free open-source video editor for Linux. It supports advanced composition operations such as keying and mattes, and many other professional functions depending on the variant.

Cinelerra has a few variants, including GG, CV, HV. The GG variant, which supports up to 8K video, and can also create DVDs and Blu-rays, is presently under active development and the only one that works in my case in current Ubuntu releases.

Download & Install Cinelerra GG

The GG edition now provides the official binary package for AppImage package.

1. Ubuntu does not support AppImage out-of-the-box since 22.04. To enable it, press Ctrl+Alt+T on keyboard to open terminal, then run command:

sudo apt install libfuse2

2. Then, select download the latest version of the AppImage from its website:

Download Cinelerra GG

Scroll down in that page and click download the latest package. At the moment of writing, it’s “CinGG-20240229-x86_64.AppImage” (for modern Intel/AMD CPUs).

3. After downloaded the package, right-click on it in file manager, then click go to its “Properties” dialog.

Next, navigate to Permissions tab and click enable “Allow executing file as program”. Finally, click Run the AppImage file to launch the video editor:

4. Create an App icon for Cinelerra.

If you want to launch the video editor from start menu or Gnome ‘Show Apps’ screen just like other normal apps. Then, click launch text editor first.

When text editor opens, create a new empty file (if it does not open a new one), then write following lines into it:

[Desktop Entry]
Name=Cinelerra GG
Comment=MultiMedia Editor
Categories=AudioVideo;AudioVideoEditing;
Encoding=UTF-8
Exec=/home/ji/Apps/CinGG-20240229-x86_64.AppImage
Icon=Cinelerra
Terminal=false
Type=Application

IMPORTANT: In the lines above, you need to replace the value for “Exec”! In my case, I moved the AppImage file into my custom “Apps” folder in user home. So, it’s “/home/username/Apps/file-name.AppImage”. You have to change it to yours!

And for icon, you need to download one from web. Either .png or .svg file. Re-name to Cinelerra.png (or Cinelerra.svg depends on image type), and put it to “.local/share/icons” directory.

When done editing the text file, click “save” (or save as), then select save the file to .local/share/applications directory, whatever name as you want with “.desktop” extension.

If everything’s done properly, you’re able to search for and launch the video editor from menu a few moments later.

Uninstall Cinelerra GG

To uninstall the video editor, just delete the .AppImage file from your file manager. Then, also remove the .desktop file from ‘.local/share/applications’ directory, as well as the icon file from ‘.local/share/icons’.

How to Install WordPress on Ubuntu Server

Last updated: April 22, 2024

Wordpress
Already installed LAMP or LEMP (Nginx with PHP, Mysql) on your Ubuntu Server? This time I’m going to show you how to install WordPress CMS.

WordPress is a popular blogging tool and a content management system (CMS) based on PHP and MySQL. It’s free and open-source.

To install WordPress, first login your Ubuntu Server as root, then follow the steps below:

1.) Create Mysql Database and User for WordPress.

    • First log into Mysql as root user: 
      mysql -u root -p

Type in the root password to get past.

  • Create a database. Change database-name in code to whatever you want. 
    CREATE DATABASE database-name;
  • Create an user. Change database-user in code to whatever you want. 
    CREATE USER database-user@localhost;
  • Give a password to the user just created. Change password-here in code. 
    SET PASSWORD FOR database-user@localhost= PASSWORD("password-here");
  • Grant all privileges to the new user. 
    GRANT ALL PRIVILEGES ON database-name.* TO database-user@localhost IDENTIFIED BY 'password-here';
  • f.) Finally, refresh Mysql: 
    FLUSH PRIVILEGES;
  • g.) Exit Mysql sell 
    exit

2.) Download WordPress and setup the configuration.

  • Download the latest wordpress: 
    wget http://wordpress.org/latest.tar.gz

    Then extract:

    tar -xzvf latest.tar.gz
  • Copy the sample configuration file to make a backup. 
    cd wordpress && cp wp-config-sample.php wp-config.php
  • Edit the configuration file: 
    vi wp-config.php

    Press I to start editing, Esc to stop editing. Press :, then type wq to save and exit, type q! to exit without save.

    Then change the section of database-name, database-user, password-here.

    // ** MySQL settings – You can get this info from your web host ** //
    /** The name of the database for WordPress */
    define(‘DB_NAME’, ‘database-name’);

    /** MySQL database username */
    define(‘DB_USER’, ‘database-user’);

    /** MySQL database password */
    define(‘DB_PASSWORD’, ‘password-here’);

3.) Setup the permissions.

    • Give ownership of the directory to the apache or nginx user by running following commands one by one:
sudo rsync -avP ~/wordpress/ /var/www/
cd /var/www/
sudo chown www-data:www-data * -R 
sudo usermod -a -G www-data username

4.) Finally in your browser go to IP or domain/wp-admin/install.php and start installing.

Enjoy!
