Recently, I activated a very small VPS: 512MB RAM, 20GB SSD drive space. It ran WordPress well under Fedora 27. However, I encountered a problem with DNF refusing to update, exiting with a kernel panic on the executable.

Turns out that a virtual server image with minimal OS config can be born without a swap file. I found this link to be useful (note that for this subsystem Fedora 27 is close enough to CentOS 7, which itself is Fedora 19):

Although my experience with web hosting servers goes back two decades, I have recently stopped hosting content for others, and no longer maintain DNS or email server infrastructure.

Given the trends of consolidation and cloud, what are the best practices to manage a digital footprint at the beginning of 2018? There are 4 fundamentals: domain registrar, dns server, email server, and web server. For bonus points, a test server.

Here is what I did, which is a strategy that would be suitable for a small business or personal presence on the Internet, or for a startup up to 10 or 20 people.

Domain registrar

I purchased the domain on which this is hosted from godaddy.com

DNS server

GoDaddy offers a terrific DNS control panel built-in — I encourage people to use it rather than giving up control of their DNS to a hosting ISP.

email server

A colleague continues to maintain an email server, and has been gracious enough to host my email. I would suggest outsourcing your email to a boutique ISP like integrationm.com, or a service like Gmail for Business.

web server

What works for me:

I leased a small Virtual Private Server (VPS) from Digital Ocean running Fedora Linux, and have configured it to host a few websites, including my personal blog using WordPress, and some vacation photos. Some people might want a server with cPanel in order to manage the server.

What you should consider as a hosted option:

Get a WordPress blog from a boutique ISP like integrationm.com or wordpress.com, or if you need a builder and commerce capabilities, squarespace.com to host the www.domain.com and domain.com for your site. Do not give the ISP control of your DNS, just ask them for the IP address and point to the hosts using your DNS control panel.

Test server

I have a test server at home, a Vista-class 64 bit dual core with 4GB RAM and a small SSD for the operating system, and a few big usb external drives formatted with ext4 and ntfs partions, running Fedora 27. I can supplement the limited resources of a very small VPS package by mounting, over the WAN, the file system on my home test server. Some of this can of course be done as a network mount like xfs or smb (windows style) over a VPN link. However, an even cleaner yet still secure approach is sshfs remote file system mount, which I predict will make many VPN setups redundant or greatly simplified in the future.

We may live in the age of the cloud but there is still room for individual expression and self-sufficiency. It’s never too late to reformat a piece of junk as a home test server.

 

This blog is my way of posting relatively uncontroversial information, like technical articles about Linux, or vacation photos. There have been times where a Google search helped me find a blog article written by somebody in 2012 that helped me fix a technical problem. I hope to pay it forward by creating similar articles myself.

Although I work as a system administrator, I have only recently renovated my personal digital presence, with a domain, a Virtual Private Server (VPS), and now this blog. I plan to follow my brother’s example in terms of blog posting, except that I plan to keep the blog hosted on the VPS rather than on bare metal running at home.

My test server at home can run of course run Linux/Apache/MySQL/MariaDB/PHP (LAMP) sites, but it is mostly a home media server and VPN server. In the next few days I will be posting about my test server and recent experiments with OpenVPN on my home network — making home resources available remotely via a VPN client, or acting as a network gateway to other computers on the network. There have been many howtos, some excellent but out of date. I will share my adaptation of another person’s suggested procedure, along with corrections and additions.

If you stick around for a few weeks, you might even see pictures of Star Trek stuff.
