Basic questions about Cluster DNS configuration

Hi friends,

I configured a Cluster DNS with:

-1 Master server (WHM/cPanel)
-3 slave servers (with 3 VPS, cPanel DNSOnly): dns1.mydomain.com -> VPS 1, dns2.mydomain.com -> VPS 2, dns3.mydomain.com -> VPS3

But I have some questions and not found replies in google. I never used Cluster DNS (I always create 3 DNS for each webhosting server). This is the last step for finalize the migration's odyssey and can forgot the old server with her problems. I'll be very grateful if you reply me this last questions:

1- I goes to Master server (WHM/cPanel) -> DNS Cluster -> "Enable DNS Clustering". I need do the same step in Salve servers or not is needed?.

2- I went to Master server (WHM/cPanel) -> DNS Cluster -> Add a new server to the cluster -> Configure -> And I added the 3 slave servers here. I keep the default options: Setup Reverse Trust Relationship = Enabled, Synchronize Zones Immediately = Enabled, Debug mode = disabled, DNS Role = Standalone.

I need do the same step between the slave servers?, for example: go to to slave server 1 -> DNS Cluster -> Add a new server to the cluster -> Configure -> Add the SLAVE SERVER 2 AND 3.

Also I need add the master server to the slave servers?.

My current configuration is: ONLY ADDED SLAVE SERVERS TO MASTER SERVER.

3- The "Standalone" mode is the correct mode? or "Synchronize changes" is better?.

4- I added this 3 new DNS to the webhosting server (WHM/cPanel -> Basic WebHost Manager -> Nameservers). But I see that anybody can add my DNS to her WHM/cPanel and send her Zone DNS to my Cluster DNS. How can I block other webhosting servers and only permit Zone DNS from my webhosting servers?.

Thanks in advance. Have a nice day.

Looking for UK dedicated providers to run Proxmox cluster

Hi there!

I currently have 3 Proxmox servers in a cluster with OVH, but their customer service is shocking to say the least.

I've been trying to find a similar provider, but I can't find anything near as comparable for the price/spec I'm after.

The spec for each server is:

AMD Epyc 7351P - 16c/32t - 2.4 GHz/2.9 GHz
256 GB ECC 2400 MHz
2500 GB SSD NVMe
UK (This is a must)
Proxmox VE 6

I don't need any managed services, just access to the bare metal.

Can anyone recommend a provider who can provide me with a similar spec and price to these? I currently pay around £200/month per server.

Thanks!

How to choose right server configuration

Hi

I am tasked to purchase a new server for our network. Basically the idea is to consolidate 2 servers with VMs into one more powerful server.
Current configuration is 2xE5-2680v4 with 128GB ram per server.

I am thinking about something like AMD Epyc 7702P with 256GB of memory, but I am not completely sure about it. Yes, this server has lots of cores, but the base clock speed of this CPU is lower than what we currently have.
I did some research and this CPU seems to be more powerful compared on a sheet, but is it on reality?

We are mainly using those servers for hosting our websites, some big databases. My question is do you think we will see significant performance increase if we do this upgrade, beside saving some money on datacenter costs (consolidating 4U into 1U server)?

Server Specs for home dedicated server

Hi all,

I'm new here and this my first post

So I'd like to get my own dedicated server and set it up at home to be used for games only but I have no idea what kind of specs that is needed when it comes to servers and the distribution of system resources such as CPU, RAM etc. Storage is self explained obviously.
I'm looking to host like a Minecraft server, 7 days to die server, Rust server etc but in general, if possible to say, how many game servers can you run on a single machine?
What is a good server Intel Xeon CPU these days that is not overkilling my needs to run a few game servers on the machine? Is 64 GB of RAM enough to start with?
What is best for my needs when it comes to the server type like a tower or a rack?

I'm just trying to get an estimated cost to set this all up and i'm a bit overwhelmed what is enough and not so my apologies if I don't provide much information so if you need any more details in order to assist, let me know and I'd be happy to be more specific in the topic .
Internet speed is not an issue as I have 1 Gbit up and down.

Thanks in advance!

Hetzner network stability

We are renting some servers in hetzner fsn (about 40) in different dcs with 10g connectivity. About 1 or 2 times in month we have network problems. 30 or 40 % of packet loss for one or two minutes.
It always connected to one datacenter . For example we have that problem with 7 servers in dc14 from 13:39:00 till 13:40:30 cest. Contacting support always leads to big works like additional logs, mtr and etc. We are losing a lot of time.
Hetzner support always says that the problem is on our side. But sometimes they propose to free exchange of server or server migration. But they never confirm problem on their side. That's all. We are using very different server configuration from kubernetes on bare metal to hyper-v vms with sql server. Most of our servers are amd epyc ax161.

The problems was really serious in December. We have constant problems (once a day) with all new servers in dc15. We resolved it by relocating servers to dc16 and problem disappeared for some months.

Currently we really don't know what to do. In march we had it 3 times with dc4 and dc13(not sure). Does someone has the problem? Can you advice hosting with great support and not very high prices?

Dedicated Server or Bare Metal Server

What is the actual meaning of Dedicated servers ? ok the answer is a dedicated server is a type of web hosting in which a client has the exclusive use of an entire server. So that mean VPS also a dedicated server. We used that word a decade ago for Bare Metal Servers. I think we should correct the WHT category as Bare Metal Servers. This is just a suggestion. What do you think about that ?

Question about dedicated server

Hello is there any guides on how to setup webhosting with cPanel etc on Dedicated Server.
I'm not a big fan of reseller hosters and is there a "limit" when you should register yourself as a business?

Hetzner DNS console: only manually add domain names?

I recently got a server (AX41-NVMe) with Plesk at Hetzner. Via the DNS console I added the base domain name, where I also want to reach the server, and that works fine.

What I'm running into now is Hetzner telling me to manually add all domain names to the DNS console in order to use them with the server. But that's crazy, isn't it? There are hosting companies that also rent the servers and they cannot manually add every domain name in the DNS console, I think.

I'm not used to it that way either. The server I rent from Leaseweb allows me to simply add a domain name to cPanel and it will be automatically recognized by the worldwide DNS servers.

For me the Hetzner DNS console is not a workable solution in this way. So I thought to solve it with the Plesk extension for Digital Ocean. Works great! But unfortunately no more than 50 domain names are allowed to be added to their DNS. I want to add 100 domains, so this solution doesn't work either.

So my question to you is:

How can I make my domain names reachable, without manually adding them all to Hetzner's DNS console?

Warning: MariaDB error in last cPanel version + Solution

Hi friends,

In last MariaDB version have an error which block cPanel Database interface with this message:

The MySQL server is currently offline.
The adminbin “cpmysql” in the “Cpanel” namespace call to function “DBCACHE” ended prematurely: The subprocess reported the “” (255) error when it ended Various sysadmins reported this error in cPanel forum, I too had him.

MariaDB version with error: 10.3.26

For solve him you have 2 posibilities:

1- Outdate to version 10.3.25, I solved him with this command:

Code:

yum downgrade MariaDB-server MariaDB-common MariaDB-shared MariaDB-client MariaDB-compat MariaDB-devel -y

2- Disable this option (this not works always, some sysadmins notified that need change MariaDB version to 10.3.25 for solve the problem):

Code:

WHM » Server Configuration » Tweak Settings » SQL » Use INFORMATION_SCHEMA to acquire MySQL disk usage

You have more information in cPanel forum: https://forums.cpanel.net/threads/th...ffline.474561/

I hope that this problem not broke your servers. Have a nice day.
