Over the course of many complex projects, I have gained proficiency in designing, implementing, and maintaining robust and scalable infrastructures. My experience covers optimizing performance, ensuring high availability, and enhancing system security while working with web servers, load balancers, databases, CI/CD pipelines, containers, and serverless technologies.

If you’re using cPanel DNS only you probably know that AutoSSL feature isn’t available on it. Reason for that is because DNSOnly cPanel installation doesn’t have web server running as classic version does. To circumvent this you may use certbot standalone mode to issue a Let’s encrypt certificate. Command you would...
To install and run PostgreSQL in FreeBSD jail you’ll need to enable allow.sysvipc system tuneable on that specific jail: List jails: jls Note jail ID and use following command to enable it for that running jail: jail -m jid=JAILID allow.sysvipc=1 This can also be accomplished by changing ezjail jail configuration...
This one is quite simple to be honest. Assuming you have Redis already installed and set up correctly you can just change your php-fpm pool definition to include: php_value[session.save_handler] = redis php_value[session.save_path] = "tcp://127.0.0.1:6379" If you’re using password for logging into redis you would...
Instead of adding all IP addresses statically to your server via host’s /etc/rc.conf file you may instead leave them out and specify them on per-jail basis. That way when Jail is started IP address gets assigned to specific network interface, and when it is shut down it disappears from that interface. This comes in...
On FreeBSD top(1) utility, although having much less command line switches and options is in fact much more powerful than one that comes with your favorite Linux distribution. Maybe one day I decide to publish an in depth write up about it but until that day comes here’s one hint. To show only processes that are...
On FreeBSD 11 sendmail is not enabled by default. Also by default, php configuration (php.ini) has sendmail binary configured for sending email so using mail() within your PHP application may not work. To resolve that you need to enable sendmail which you can do with: # sysrc sendmail_enable="YES" sendmail_enable:...
So, app was connecting from jail’s public IP to the MySQL and that didn’t worked since I had user created like: USER@localhost Instead of: USER@% or USER@JAILIP And that got me confused badly. I would like to thank Mark for clarification.
Recently I had to discover custom SSH port on the server so I needed to come up with a somewhat quick way to check for open ports on the server. To do that simplest and prettiest solution I’ve found was using netcat utility. As you can see by looking at syntax I prefer OpenBSD one.
In previous article I’ve explained how to add IPv6 to your server, now it’s time to show you how to assign IPv6 address to Jail running on your IPv6 host. I’m using ezjail at this moment to manage my Jails. If you’re like me you can use following command to assign already configured IPv6 address to your Jail at...
This article will be one of the few to come in the near future. I’m in the process of switching my VPS servers from various VPS providers to dedicate box I’ve leased at Hetzner. Up until now I’ve mostly used CentOS on my server systems but it is time to switch to FreeBSD now, various reasons but that’s a topic for...
Recently I have started thinking about backups on my personal web server (on which this blog is hosted on). Simplest solution I have come up with is to just mount additional drive to the server, format it as ZFS, sync stuff to it and then just snapshot that drive. This way I don’t use much space for storing backups...
If you were fast on a trigger and upgraded to Fedora 25 as soon as it was available and you use Owncloud client for your syncing needs you may found yourself that Owncloud client doesn’t start. You may have also noticed an that it causes an error while trying to perform an upgrade to newest release. Error that I got...
