CentOS Upstream: Isn't okay for Production Servers anymore?

I assume you mean CentOS Stream?

Honestly it is a more viable solution for a Linux server than CentOS ever was as it is no longer so out dated.

But, I would give the entire RHEL ecosystem a wide berth at this point.

@Pete-S said in MariaDB Package Issues While Updating from CentOS 7 to CentOS 8:

But nobody in their right mind...

...uses LTS releases. So we have to accept we are working from a crippled situation anytime that this comes up. It means we are already dealing with politics over function. So knowing that, it should explain why we have to deal with what we have to deal with. Would have been super fast to do a fresh install.

But you'd not do a fresh install of CentOS 8 or Streams if it wasn't for politics. We'd be putting in Fedora, Ubuntu, or OpenSuse. So not getting to do a fresh install is just one artefact of many when doing what's best for the application platform isn't what drives decision making.

@DustinB3403 said in Oracle Linux Installation and performance seems insanely bad:

@Obsolesce CentOS as a product is dead, the alternatives are RHEL or CentOS Stream.

CentOS Stream is a totally different thing. Not what people consider alternatives. It is an alternative in the same way that Ubuntu or Windows is.

The real alternatives that are drop in replacements that work exactly the same and cost the same are Oracle Linux, AlamLinux and Rocky Linux.

@scottalanmiller said in New to Linux Administration: RHEL-Based or Debian-Based OS:

I agree, both is the obvious choice. But to truly answer the question, I'd focus on Ubuntu (not Debian) and then RHEL. Debian is great, but it is Ubuntu specifically that has the market.

Yes, almost the same is never the same as exactly the same.

@gotwf said in SAMIT: IBM Is Killing Off CentOS:

@scottalanmiller Yes. This I know. But this isn't bare metal but rather SmartOS hypervisor in a Triton datacenter. So I presume all is atop ZFS. I never delved deeper so honestly do not know.

Hopefully not, as ZFS isn't all that fast. But you need XFS touching WiredTiger... what's lower in the stack isn't what it is concerned with. You still control your own filesystem regardless of what the datacenter may or may not use elsewhere.

@Pete-S said in How to use firewall-cmd to verify that tcp 80 & 443 is open?:

One thing that would be nice to have, something that I've used on hardware firewalls, is a command that will simulate packets through the firewall rules to see if they will pass or not.
I've not seen something like that for iptables/netfilter.

Not sure about simulating, but you can always send packets at it and use iptables -v to see the counters.

@black3dynamite said in Install Skyetel Postcards on CentOS 7:

Still preferred fallocate instead of dd to create a swap file?

dd if=/dev/zero of=/swapfile count=4096 bs=1MiB && chmod 600 /swapfile && mkswap /swapfile && swapon /swapfile && echo "/swapfile swap swap defaults 0 0">>/etc/fstab

Still using swap file? Memory is cheap. I don't recall a server where I created swap partition or swap file.

Memory is NOT cheap, not at all.

It is if you own it. If you rent your hardware, yeah, it adds up.

Even if I own it, throwing away 2-3GB of RAM makes no sense. Now, if I own it, I can easily assign 4GB of RAM then remove it once installed, by why? That's harder to script and still no benefit.

It's a bad habit to see resources as cheap and so waste them just because you can. Extra memory doesn't improve performance, it hurts it (just the tiniest bit). And it's not free, if you always apply twice as much RAM as you use (or four times, here), that gets costly one way or another. Either you wasted money overspeccing in the beginning, or you are stuck buying more now.

@scottalanmiller said in Deploying NodeBB 1.14 on CentOS 8 with MongoDB 4.2:

By default, NodeBB uses the REDIS NoSQL database,

By default, in 1.15.x it uses Mongo

I'm pretty sure it did in the last version I installed also. But that was months ago and I do not recall clearly.

If you install using the above method, it never tells you the random password assigned to your management interface. But no fear, there is a tool that sets that for you and is super, duper easy.

cd /usr/local/lsws/admin/misc sh admpass.sh

It is interactive. And voila.

@JaredBusch said in Deploying NodeBB 1.13 on CentOS 8 with MongoDB 4.2:

You can only remove this line if you are going to host the reverse proxy on the same instance.

No reverse proxy needed if you are going to just look at it locally without going over the network.

Turns out that there was a wildcard A record in DomainA2.com

The last time I set up Graylog I had to configured SELinux.

Allow the web server to access the network:
sudo setsebool -P httpd_can_network_connect 1

Graylog REST API and web interface:
sudo semanage port -a -t http_port_t -p tcp 9000

Elasticsearch (only if the HTTP API is being used):
sudo semanage port -a -t http_port_t -p tcp 9200

Allow using MongoDB default port (27017/tcp):
sudo semanage port -a -t mongod_port_t -p tcp 27017

@scottalanmiller said in Installing Hugo Static Website Generator on Linux:

However, they don't have any standard Linux install documentation on their website and only show using Homebrew, a MacOS package that essentially no one on Linux uses. Very odd.

I just looked. I'm not sure what you're talking about. The page clearly shows snaps, dnf, apt, pacman, eopgk, and pkg_add for OpenBSD.

https://gohugo.io/getting-started/installing

Completely different than what I got from the same link this morning. I went to that page, clicked on Linux, and they only showed Brewlinux, which isn't even the current name of the system.

Way back machine shows it's been there since at least the 13th.

https://web.archive.org/web/20191113183617/https://gohugo.io/getting-started/installing/

Very weird. I wonder if it was a cache somewhere? I definitely poked around this morning and Linuxbrew was the only thing that it had and had it from every link that I tried on their site.

Finally released!!

@Pete-S said in UREs Strike InnoDB on MySQL:

Step one is to remove the drives and clone them with dd or recovery tool to a new drive.
You could probably recover 99.9% of the data - if you want.

As you can guess from all of their previous issues, they don't want to pay for any recovery, they just want it magically fixed for free. They don't own any storage onto which to clone it, either.

Then what is the point of any of it? It appears to have zero value to the business.

I said that to them.

I can't read the phrase "kernel panic" without thinking of this tune:

@DustinB3403 said in MySQL MariaDB password reset without knowing the password:

Just still seems weird to have the password in plaintext on in a config file.

has to be somewhere, how else can an application connect? Look at WordPress, for example, you have to enter the password into the application so that the application can connect to the database. Otherwise, the database would have to have no password protection at all or you'd need a human to log in and enter the password every time a database connection was needed (which is normally thousands of times a minute.)

@wrx7m said in Configure Nginx as Reverse Proxy for ScreenConnect to Enable Lets Encrypt:

Less to that than I thought there would be.

It's surprisingly simple and basic. It's really just passing one port to another, and using SSL. About the most basic setup you can have.

@JaredBusch said in Prerequisites for Yealink YDMP Install:

@DustinB3403 worked with this I believe...

I did, but the install process was pretty easy.
