This quick‑start guide walks you through turning a fresh Ubuntu 20.04 server into a fully functional Chamilo LMS site in under twenty minutes, starting with the basic prerequisites of Apache, PHP 7.x, and MySQL/MariaDB. It details how to update packages, secure MySQL, create a dedicated chamilo database and user, download the latest Chamilo release, set proper ownership and permissions, configure an Apache virtual host with rewrite support, and edit the configuration file to point at your database credentials. After launching the web installer from your browser you’ll finalize site settings, establish an admin account, and then tighten security by enabling UFW for HTTP/HTTPS traffic and disabling PHP’s display_errors directive. A quick sanity check—verifying database connectivity, a 200 OK response from Apache, and the appearance of the Chamilo login page—ensures everything is running smoothly before you begin building courses.
This guide walks you through setting up MyWebSQL on an empty Ubuntu 20.04 server by first installing the LAMP stack and essential PHP extensions, then pulling the latest release from GitHub and moving it into Apache’s web root. Once the files are in place, you copy a sample config file, edit it with credentials for a dedicated MySQL user, grant that user full privileges on all databases, and adjust ownership so the www‑data process can read and write where needed. You then test the installation by visiting your server’s IP followed by /mywebsql, logging in with the new user, and verifying that the dashboard loads and lets you run queries across any database on the machine. Finally, optional steps such as opening Apache ports through UFW and enabling services to start at boot are covered, along with a cautionary anecdote about how an unexpected PHP upgrade can break the setup if version pinning is not handled.
The guide walks you through setting up a fresh vtiger CRM instance on CentOS 8 in under an hour, covering package updates, web server and database installation, PHP configuration, and security hardening. It begins by updating the system and adding EPEL for extra PHP modules, then installs Apache with automatic startup, MariaDB with secure credentials, and a comprehensive set of PHP extensions needed to satisfy vtiger’s Composer bootstrap. After tuning php.ini for memory, execution time, file sizes, and timezone, you open HTTP ports in firewalld, create an UTF‑8mb4 database user, download the latest community release from SourceForge into /var/www/html, and adjust ownership and permissions so Apache can read and write the files safely. Finally, optional SELinux context adjustments are suggested, a symbolic link is created for easier access, and you launch the web wizard to complete the configuration while watching out for common database connectivity issues; once finished, vtiger runs ready for lead management.

The article walks readers through installing Suricata on Debian 11, starting with the prerequisites and adding an upstream repository to get the latest stable release. It covers how to install the core packages, configure the network interface in suricata.yaml for optimal throughput, and enable rule sets using suricata-update. The guide also shows how to start and verify the Suricata service, providing commands to check its status and tail logs for alerts. Finally, it lists common pitfalls such as binding conflicts and missing libpcap-dev, offering quick fixes and tips for troubleshooting.

The guide shows how to install procs, a lightweight yet powerful tool that replaces the cluttered output of ps and top with a clear, hierarchical process tree. It walks through package‑manager commands for Debian/Ubuntu, Fedora/RHEL, and Arch Linux, while pointing out that you can fetch the source from GitHub if your distro lacks it, then demonstrates the basic command procs that prints PID, PPID, CPU%, MEM%, user, and command columns in a neatly indented format. Readers learn to fine‑tune the output with grep filters, --sort options for cpu or mem, JSON piping into jq for automated alerts, and even custom column sets like pid,ppid,user,cpu,threads,command to spotlight the metrics that matter most when diagnosing performance issues. Finally, the article reminds you that while procs is perfect for quick snapshots on a headless server, interactive tools such as htop are still the go‑to choice when you need real‑time graphs or a full TUI, and encourages everyone to try procs to bring order to process chaos.
The post explains how to get pip working for Python 3 on a fresh CentOS 8 machine, pointing out that the default distribution ships only with Python 2.7 and its own pip. It walks readers through updating the system, enabling the EPEL repository, installing python36 from the base repo, then either pulling in python36‑pip or bootstrapping pip via ensurepip to create a functional pip3 binary. Once pip3 is verified, it recommends upgrading it with sudo pip3 install --upgrade pip while noting typical hiccups such as missing EPEL or confusing Python 2’s pip for the new one. The article concludes by showing a quick sanity check—installing tqdm—to confirm everything works and encourages developers to start pulling packages from PyPI on their CentOS 8 box.
This guide explains how to pull precise battery statistics on Linux with a handful of terminal commands, starting with upower for a full report that mirrors what the desktop environment shows. It then walks through inspecting raw kernel data under /sys/class/power_supply/BAT0, where files like capacity and voltage_now reveal the true state when GUI readings become misleading. A quick acpi -V snapshot offers a one‑liner status perfect for SSH sessions, while time estimates from upower or acpi provide rough runtime predictions. Finally, the article cautions that stale UPower caches can give false 100 % readings and suggests restarting the service to refresh the display.
Webmin provides a convenient interface for keeping system logs from overflowing, letting administrators locate the log module, edit rotation policies, and add new log files without diving into shell commands.
By setting parameters such as frequency, maximum size, and backup count, users can tailor how often logs rotate, cap their growth, and control retained history to balance auditability with disk space.
The guide also explains how to configure alerts that trigger when a log exceeds a threshold, as well as manual cleanup steps through File Manager and syslog filter rules to drop unwanted messages.
Overall, the article encourages maintaining lean, searchable logs while avoiding pitfalls like SSH hangs due to bloated files, and offers practical tips for staying ahead of storage nightmares.
