Atlantic.Net Cloud – How to enter single user mode for Centos Cloud servers

Verified and Tested 02/28/2015


This article will show you how to enter single user mode for maintenance of multi-user environments or changing/resetting a lost superuser password of Centos servers.

Why do I need this?

My cloud server will only enter read-only mode, FSCK complains about permissions, or I need to make sure no one can access my server while I make security changes.

I forgot my cloud server password and I would not like to use the automated password reset feature (see https://www.atlantic.net/cloud-hosting/how-to-resetting-atlantic-net-cloud-server-password/).

You will need to access your cloud server using the provided VNC. See the following URL on how to access the server: https://www.atlantic.net/cloud-hosting/how-to-using-vnc-access-cloud-server/.

Entering Single User mode for Centos

Once you have decided that single user mode is the only way you can, or want to proceed, you will need to VNC to the server. Don’t worry about logging into the server at this point, since this process will need you to reboot the server.

From the cloud portal issue a hard reboot, instructions here: https://www.atlantic.net/community/howto/soft-or-hard-reboot-a-atlantic-net-cloud-server/

Once you issue the hard reboot, you will need to click refresh at the top right of the VNC screen since the hard reboot will reset that connection. You need to click this refresh very quickly otherwise you will miss the boot screen where you can interrupt the boot process.


When the server starts to boot, you will see a GRUB menu/screen. You will need to interrupt the boot by pressing any key.


Now you can edit the default kernel your system boots to. By default, the most recently added kernel is at the top of the list and is the default kernel. This kernel should already be highlighted for you.

Press e to edit.


Go to the line that starts with kernel, and press e to edit.


Add the word “single”, no quotes needed, to the end of the line and then press Enter.



Press b to boot into the newly edited kernel.


Now you are in single user mode. You may perform actions such as FSCK, passwd, and other commands for maintenance.

GE Says its New Apps are “North of 90%” Public Cloud

General Electric’s head of IT told InfoWorld editor Eric Knorr in October that the company was moving aggressively toward the public cloud, with 90% of new systems built within that environment and moving to 100% public cloud over the next 15 years:

  • Why General Electric’s Announcement is Important
  • General Electric’s Vision – Beyond Hybrid
  • Tomorrow vs. 15 Years
  • Big Data and the Massive Scale of GE
  • Total Cost of Ownership

Why General Electric’s Announcement is Important

Although the incredible investments into cloud infrastructures – most prominently Amazon, Microsoft, Google, and IBM – have brought increasing attention to the public cloud, the technology often gets little respect. Many firms still don’t trust the multi-tenant environments of cloud service providers, at least not with their most sensitive applications.

Censorship Workarounds, Part 3: Windows Cloud Server for Anonymity

<<< Part 2 – How to Set Up a VPN

We started out this series by talking about the extent to which censorship and site-blocking are common ways that the Internet is controlled around the world. For those who want to access sites that they otherwise could not, or for those who want access to the user experience in various areas (a great way to expand your comparison shopping by checking numerous regions), a VPN (virtual private network) is a viable solution. One way to surf the Internet encrypted and anonymously is with a more full-featured and robust option than a VPN service, a Windows cloud server.

5 Tips to Optimize Cloud Security for Developers

If it’s a popularity contest, cloud is winning.

February 2014’s State of the Cloud Survey gathered information and perspectives on cloud computing from 1068 IT executives throughout a broad spectrum of economic sectors. 24% of those who completed the survey were from enterprises employing 1000+ people. This year’s results show that cloud has exceptionally high acceptance, with 94% of companies either using cloud applications or Infrastructure as a Service (IaaS; also called Hardware as a Service, or HaaS). 87% of companies are at least partially integrated with a public cloud while 74% either have a hybrid cloud in place or are planning a transition to that model.

CPanel Cloud Servers are Available at a Low Hourly Rate

CPanel is a privately held company that was founded in 1997. Headquartered in Houston, Texas, the company originally designed what is considered by far the most popular Linux control panel for hosting websites and managed cloud servers. CPanel cloud hosting & WHM, the two integrated halves of the software, make server automation simple and intuitive so that website owners and hosting companies can spend less and reduce their manual workload. This system is widely considered to be the first server control panel available on the market. Both the laser focus by cPanel on its one (bipartite) continually improving application and a widespread familiarity with the platform practically give the company a monopoly on the website control panel for those using Linux.

Financial Stability of Cloud Providers

This video – “Cloud Hosting Companies Are Dropping Like Flies” — discusses that many cloud hosting companies are shutting down. That makes sense. There has been a huge amount of money injected into the cloud hosting industry, which means there have been many startups. When it comes down it, a startup is a test business. They haven’t proven themselves capable of maintaining solvency. While you may want to run technological test projects yourself, you never want to serve as a guinea pig in an infrastructure experiment since that puts your online presence at risk, especially if you’re hosting mission-critical information, such as that which may require HIPAA cloud hosting.
