In this week’s feature highlight, we look at How to Install LAMP Stack on AlmaLinux 8
A LAMP stack is a group of open-source software that is typically installed together to enable a server to host dynamic websites and web apps. This term is actually an acronym which represents the Linux operating system, with the Apache web server. The site data is stored in a MySQL database, and dynamic content is processed by PHP.
Install Apache Web Server
First, we will start by installing the Apache web server. To complete the installation, use the following command.
Once the installation is complete, enable Apache (to start automatically upon system boot), start the web server and verify the status using the commands below.
systemctl enable httpd
systemctl start httpd
systemctl status httpd
Output:
[root@server ~]# systemctl status httpd
● httpd.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor prese>
Active: active (running) since Mon 2021-02-08 15:03:51 EST; 5s ago
Docs: man:httpd.service(8)
Main PID: 26398 (httpd)
Status: "Started, listening on: port 80"
Tasks: 213 (limit: 23680)
Memory: 29.1M
CGroup: /system.slice/httpd.service
├─26398 /usr/sbin/httpd -DFOREGROUND
├─26399 /usr/sbin/httpd -DFOREGROUND
To make your pages available to public, you will have to edit your firewall rules to allow HTTP and HTTPS requests on your web server by using the following commands.
Now restart your web server so that Apache knows that it will be serving PHP requests as well.
systemctl restart httpd
Test your PHP, by creating a simple info.php file with a phinfo() in it. The file should be placed in the directory root for your web server, which is /var/www/html.
MariaDB is a popular database server. The installation is simple and requires just a few steps as shown.
yum install mariadb-server mariadb
Output:
[root@server ~]# yum install mariadb-server mariadb

systemctl enable mariadb
systemctl start mariadb

Finally, you will want to secure your MariaDB installation by issuing the following command.
mysql_secure_installation
Output:
[root@server ~]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] asdfghjkl
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
Once secured, you can connect to MySQL and review the existing databases on your database server by using the following command.
mysql -e "SHOW DATABASES;" -p
Output:
[root@server ~]# mysql -e "SHOW DATABASES;" -p
Enter password:

In this week’s feature highlight, we look at how to change the Hostname of your VPS on CrownPanel.
Before learning How to set the Hostname in CrownPanel, let us learn what is a Hostname.
A hostname is a domain name assigned to a host computer. For example, if Computer “A” had two computers on its network named “A1” and “A2,” the domain name “A1.abc.com” is connecting to the “A1” computer. A hostname may have appended the name of a Domain Name System (DNS) domain, separated from the host-specific label by a period (“dot”) then the hostname is said to be a fully qualified domain name (FQDN).
OpenVZ Based VPS
OpenVZ VPSes pull the hostname from the config file which is updated when setting the hostname via our panel
Login to https://crownpanel.com/ and click on the “Manage” button beside the VPS you wish to edit the hostname for.
Next click on the “Hostname” listed beside the IP address,
This will open a new form where you can edit the hostname as you wish. Once the hostname is edited/changed, the VPS hostname is updated.
KVM Based VPS
Click on the “Manage” button beside the VPS you wish to edit the hostname for.
Next click on the “Hostname” listed beside the IP address,
This will open a new form where you can edit the hostname as you wish. Once the hostname is edited/changed, the VPS hostname is updated.
CentOS
How do I see the Host names?
hostnamectl
OR
hostnamectl status
How do I set the Host name? The new hostname can be set with the following command,
In this week’s feature highlight, we look at how to set arDNS in CrownPanel.
Before knowing what is rDNS first let us learn what is DNS,
DNS is typically used to resolve a domain name to an IP address and this function is known as a forward resolution and is performed every time you visit a site on the internet.
rDNS which is known as Reverse DNS as its name implies it is a method of resolving an IP address back to a domain name.
Please note,
You will need to setup a A record on your domain to point to the IP, for eg, if you wish to setup my.domain.com on IP 127.0.0.1, then my.domain.com will have to have a A record pointing to 127.0.0.1. If this is not possible to do, please contact us via the Client Area to setup your rDNS manually.
Most IP(s) should be available to setup via the automated module, in some cases, you may see a message saying “Click here to contact our support team to setup rDNS for this IP Address” for these you will need to click on the message button to open a support ticket.
In this week’s feature highlight, we will look at how to set a label on a VPS in CrownPanel.
Labels are identifiers for your VPS’s to easily mark and/or group servers together, You can set the VPS labels and color according to your usage of the server.
Setting labels on a VPS is easy as it gets:
First, Click on the “Manage” button beside the VM you wish to Label
Next, Switch to the “Label” Tab.
Next, Click on Add Label to add the label to the VPS.
Here, you can fill in the Label Text and select the Colour you wish to use from Red/Green/Blue. Then, Click on Add Label to Confirm.
After setting a label on a VPS it will look like this,
You can remove Label by clicking the Cross mark as shown in the below screenshot.
In this week’s feature highlight, we look at how to use SSH keys with your KVM VPS on CrownPanel.
SSH (Secure Shell) is a widely-used protocol for interacting with remote servers for configuration and general usage. SSH keys provide a more secure way of logging into a server with SSH than using a password alone.
Here just a few easy steps to add a new key and use it.
Click on “SSH Keys” in the navbar,
Click on “New Key” to add a new SSH key,
Once the key is added, switch to the “VPS List” from the navbar,
Click on the “Manage” button beside the VPS you wish to manage,
Switch to the “Reinstall” tab and you can now select your SSH key,
