HaProxy is a remarkable tool that notably allows for load balancing or reverse proxying. It’s this latter functionality we will be focusing on.
The goal is to make two different web servers accessible from the same IP address and port via two subdomains.
An important step when deploying an Apache2 server is the transition from the HTTP protocol to HTTPS. This allows for the encryption of data between the client and the server to protect its content from being transmitted in plain text over the internet.
Setting up DKIM (DomainKeys Identified Mail) on a server is essential for authenticating emails sent from that server. This ensures that the email content has not been altered during transit.
I encountered a rather constraining issue for sticklers like me; I have my mail server hosting Postfix and Dovecot duo. The logs are respectively distributed in /var/log/mail.log for Postfix and /var/log/mail.log for Dovecot. Problem is, when sending these logs via Rsyslog to the receiving server, I ended up with a concatenation of both files into one. Let’s discover the solution to this problem together!
For certain needs, it may be necessary to execute a script via crontab by a user other than root. In this tutorial, I will use www-data because my script will be related to my Apache server.
WireGuard is a very lightweight and easy-to-configure VPN that operates on a P2P system. It is available on many platforms like Windows or Android and is incredibly stable!
The goal of this tutorial is to set up a WordPress server. For this, we will install and configure Apache and MariaDB. You can use this tutorial for another tool like GLPI, but you will obviously need to check the official website for the required PHP packages.
After a new installation, the main disk on which Proxmox is installed consists of two partitions.
local and local-lvm
By default, the virtual machines and containers will be stored on the local-lvm partition.
And on the local partition, the backups, templates, and iso files will be stored.
If you have a second disk or several in a raid, it may be useful to delete the local-lvm partition in order to allocate its space to the local partition to store more content (backups, iso, template, etc.).
Here’s a brief overview of basic Linux commands.
It can be useful to be able to remotely power on one of your computers.
In this procedure, we will see how to configure Wake On Lan, which allows you to send a “magic packet” to the powered-off machine to start it through the WAN.
