Use composer global require without sudo AND without permission errors

Composer is not supposed to be ran as sudo / root, but at the same using the global (or -g) argument might give us permission errors. To fix this, we need to change ownership of the ~/.composer directory to the current user:

$ sudo chown -R $USER:$USER ~/.composer

I’ll go step-by-step on how to create a virtual host in the XAMPP environment. As we know, the default http://localhost points to /opt/lampp/htdocs as the root directory. The desired result is to be able to visit http://examplevhost.local, with the root directory being /opt/lampp/htdocs/examplevhost.

Note: The steps below are done on Ubuntu 16.04, but they should also work on most other Linux distributions (Debian, Mint, Arch).

Note: I’ll assume that XAMPP is installed in /opt/lampp/. If it’s different on your setup, please read carefully and adjust accordingly.

Enable virtual hosts in apache configuration file

Note: This should be done only once per XAMPP installation. If you want to add another virtual host later you can skip to the next step.

The POL Way

Normally the Microsoft Core Fonts can be installed like this:

• Click Configure
• Select the prefix where you want the fonts installed
• Tab Install components
• Select Microsoft Core Fonts from the list and click Install

Manually

After installing XAMPP on Linux, the htdocs folder (default: /opt/lampp/htdocs) can only be written to by root. Although this is normal since the installer has been executed as root, we would still like to be able to create, edit, and remove content from htdocs within our file manager or text editor, without the need for sudo.

Requirements:

• XAMPP installed
• sudo

Note: The steps below are done on Ubuntu 16.04, but they should also work on any other Linux distribution.

Warning: These permissions are safe on local environments such as XAMPP. I do not recommend using this for production.
