Intro

I wanted to quickly take Laravel Octane beta for a spin, as we have been using Swoole for some time and wanted to see how official support performs vs what we have.

Test 2: Forge server

Next test is more real world as we now have a web server and database server within a VPC.

Using Laravel Forge

#!/usr/bin/env bash
# As root

# Make config and data dirs
mkdir /etc/composer -p || exit 1
mkdir /var/lib/composer -p

# Set composer home dir to global location
cat << EOF > /etc/profile.d/composer.sh
#!/usr/bin/env bash

Because of GitHub's rate limits on their API it can happen that Composer prompts for authentication asking your username and password so it can go ahead with its work.

If you would prefer not to provide your GitHub credentials to Composer you can manually create a token using the following procedure:

Create an OAuth token on GitHub.

Add it to the configuration running composer config -g github-oauth.github.com <oauthtoken>

Now Composer should install/update without asking for authentication.

To install Pulse Secure for Ubuntu 20.04, it is a bit complicated since the support isn't great.

First, we'll want to go through the form at https://www.pulsesecure.net/trynow/client-download/. You'll get an email with download links to the latest versions of pulse secure. Download the Linux one with the deb file and then you can install it using dpkg from your downloads folder.

$ cd ~/Downloads
$ sudo dpkg -i ps-pulse-linux-[your-pulse-version]-ubuntu-debian-64-bit-installer.deb
