Configuration:

The configuration process involves several steps:

All the steps will be discussed herein, but separate detailed instructions can also be found here: Install a Custom Distribution on a Linode

Before we begin, let's discuss a couple topics.

A hosted VM service like Linode requires some sort of “console” access, Linode offers several. Using the Linodes → Remote Access tab, view the available options.

Console Access

More Info: Using the Linode Shell (Lish)

Additionally, Linode offers a “Shutdown Watchdog”, enabled by default using the Linodes → Settings tab.

Lassie

We mention this since your AstLinux “reboot” will only act as a “poweroff” if Lassie is disabled.

OK, let's begin …

Using the Linodes → Dashboard tab, create an installer disk (200 MB) and a boot disk (8000 MB), both of type “unformatted / raw”.

Create Installer Disk

Create Boot Disk

Using the Linodes → Dashboard tab, create two configuration profiles, one to run the ISO installer, the other to boot AstLinux.

Installer Profile:

Tip -> Don't miss that the boot device is set to /dev/sdb

Installer Config

Boot Profile:

Boot Config

Using “Rescue Mode” dd copy the AstLinux ISO Installer to the raw installer image, we boot into the rescue Linux image to copy the AstLinux Install ISO onto the raw installer disk. Note where the installer disk is mounted, assuming /dev/sda.

Rescue Mode

Click “Reboot into Rescue Mode” using Linodes → Rescue

Access Lish via “Lish via SSH” using Linodes → Remote Access

This example command copies the AstLinux 1.3.3 “Guest VM x86-64bit” ISO onto /dev/sda, adjust accordingly. 

curl -L --capath /usr/share/ca-certificates/mozilla https://astlinux-project.org/mirror/downloads/iso/astlinux-1.3.3-genx86_64-vm.iso | dd of=/dev/sda

Look for any errors with the curl and dd commands.

Now we are ready to launch the installer, exit the “Lish via SSH” console.

Dashboard Install

Select “Installer-astlinux-1.3” and click “Reboot” using Linodes → Dashboard

Access Glish via “Launch Graphical Web Console” using Linodes → Remote Access

Installer

Select the “Install” installer menu, follow the dialogs to install an AstLinux image to your virtual disk.

When finished do not select the “Shutdown” installer menu, if you did Linode's Lassie would just restart it.

Dashboard

Select “Boot-AstLinux-1.3” and click “Reboot” using Linodes → Dashboard

Access Glish via “Launch Graphical Web Console” using Linodes → Remote Access

AstLinux

Finally, configure AstLinux using the normal setup.

Tip -> Note the “IPv4 Address:” on the screen and access the VM with SSH or an HTTPS browser from anywhere.

Warning -> It is important to enable the Firewall as soon as possible. Create rules with limited access for TCP ports 22,80,443 (SSH/HTTP/HTTPS) from trusted public addresses.


Out-of-Band Console Access:

Out-of-Band Console Access is an optional feature, but very useful, so enable it.

After you have AstLinux setup with persistent storage and firewall rules applied, out-of-band console access is enabled by editing the /etc/inittab file.

Change this line… 

# ttyS0::respawn:/sbin/getty -L 115200 /dev/ttyS0 vt100

to this… 

ttyS0::respawn:/sbin/getty -L 19200 /dev/ttyS0 vt100

Tip -> You may want to replace vt100 with xterm-color as the TERM variable setting.

Reboot AstLinux to apply the change.

Below is a sample session to access AstLinux box “linode” via the Linode Shell (Lish).

More Info: Using the Linode Shell (Lish) 

## Where <user> is your Linode username
## Where <location> is: dallas, newark, frankfurt, etc.

Tip -> Access occurs via a screen console session.

To exit, type Control-A then D then D and finally exit to return to the starting shell.
