OK, if you are not running apache or nginx, you should install the php-cli package instead.

So that seems to get installed anyway as a dependency on its own.

Yes, it does. But by using the php package and not php-cli, you probably got apache installed on your system as well - by dependencies.

You could find out by running: apt list --installed | grep apache

Or systemctl status apache2 to see if it's running.

Even if it was, Laravel uses Artisan's server.

I'm guessing they are invoking php's built-in webserver.

Regardless, the point is that if you swap php to php-cli in your install guide you don't get apache and other stuff you don't need.

Yeah this is bread and butter for config management tools. You'd either use a template for the config or the lineinfile module for Ansible.

Your template would have something like this:

PermitRootLogin {{ root_login_enabled }}

In it and then you can control which servers allow root login with the root_login_enabled variable.

@Pete-S said in Searching for text in file:

If you have a text file that looks like this:

start_folder='/folder1/abc.txt' iterations='123' passphrase='xyz' last_command='invoke' return_value='0'

How can you pick out just xyz when looking for "passphrase"?

I know grep will get me the line but what should I use if I want just a part of the line?
Can it be done in one command or do I have to pipe several together?

If you the text has a character that would be a good delimiter, you can pipe grep to cut... ie:

cat myfile.txt|grep "iterations"|cut -d '=' -f 2 Output: '123'

the -f # is which column you want.

There may be other ways to do it, but that's the first way I can think of.

You can specify a file with grep, no need to pipe in from cat.

This is true! I always seem to get it backwards when I do that, so i just cat $thefile | grep | blah ... Cuts down on frustration, ha ha.

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.

I ran some test on a VM and created some groups and added some top-level directories for those groups.

Changed the group on each top-level directories and files below recursively with chown -R.

Set directories to permission 2770 and files to 0660 with chmod -R.

Changed smb.conf and added create mask=0660 and directory mask=2770.

Now new files and directories created on the share have the right permission and belongs to the right group automatically, simply depending on what group the top-level directory belongs to.

If you're not a member of a group, you will not even see the directories or files that belongs to that group.

I think this is a good interim solution without too much work. Then moving to onedrive or whatever can be done in the future on a department to department basis.

Only admin required for adding users is to add them to linux/samba and make sure they become members of the right groups.

It's also very simple to make a separate share out of the top-level folders if you wanted.

@EddieJennings Good info thanks eddie!

You're welcome. My RHCSA videos are truly "practice sessions" for me, but the information should be accurate. 🙂

if you want to also know the progress you can pipe it to pv, like in the below example

ssh [email protected] "sudo dd if=/dev/nvme0n1" | pv | dd of=/Users/someuser/Desktop/mydisk.img

TY @black3dynamite

Just install one of the old supported OSes on another drive, reboot and run the firmware update. It's a self extracting executable.

With HP and Dell, it's their intention to support you by providing an additional layer of management on top of the actual manufacturers product. But you have to be in warranty to be able to leverage that support. If you intend to run equipment longer than the 5 year warranty, don't use Dell or HP or live without any firmware upgrades or support. If you use Dell or HP, replace hardware when it's out of warranty.

HP Gen8 servers are from 2012-2013 so 7-8 years old and not the best candidates for new installations.

To do that....

Edit...

sudo vi /etc/libvirt/qemu.conf

And set...

user = "root" group = "root"

And then...

sudo systemctl restart libvirtd

@Seb1982 said in Ubuntu 20.04 Desktop Lag:

My Dell XPS 13 lags after upgrading to 20.04. All graphics are fine, but the system simply does not respond quickly enough. Sometimes all is fine, but often the pointer is about half a second behind, so is typing.

And, I assume, it was snappy under the previous version?

Since the initial issues, mine has stayed responsive.

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.
