This guide walks Fedora users through installing Slack on version 38 or newer, beginning with a quick system update to avoid dependency snags. After verifying your system is current, it shows how to download the official RPM from Slack’s website, install it via dnf—which automatically resolves libraries—launch the app to create its configuration folder, and highlights why Snap versions often fail due to sandbox restrictions. It also offers a flatpak alternative for those who need isolation, noting that this route consumes more disk space and starts up slower, so the author advises using the native package unless sandboxing is essential. Finally, the tutorial explains how to keep Slack updated with dnf upgrades, clean up old menu entries, and remove the application cleanly without leaving residual configuration files.
This guide shows how to install MySQL Tuner on the server that actually runs your application and run it against a busy database so you get real‑time performance data.
After interpreting the tuner’s output, you learn which configuration options to change in my.cnf—such as increasing the InnoDB buffer pool size, disabling the deprecated query cache on newer MySQL releases, and enabling a low threshold slow query log—to capture problematic statements.
The tutorial then walks you through adding indexes, running ANALYZE TABLE to refresh statistics, and seeing how these adjustments cut response times from seconds to milliseconds.
Finally, it reminds you to run the tuner again after major updates or traffic spikes so that the database stays tuned as your schema grows.
This quick‑start guide walks you through installing GitLab on a fresh Debian 10 or 11 machine, from system preparation to getting your first repository online. First it updates the base packages and installs essential tools such as curl, openssh-server, ca‑certificates, tzdata, and perl. Then it pulls in the official GitLab repo by importing its GPG key, adding the correct codename line for bullseye or buster, installing the omnibus package with an EXTERNAL_URL, running gitlab-ctl reconfigure, and opening HTTP/HTTPS firewall ports. Finally it highlights common hiccups like missing tzdata or a wrong codename, shows how to verify services are running, and explains how to tweak /etc/gitlab/gitlab.rb for custom settings before you start inviting teammates.
The article explains how to locate the default Nginx access and error log files, which live in /var/log/nginx by default but may be elsewhere if configured differently. It then walks through real‑time monitoring with sudo tail -f, shows how to stop it, and why catching a 503 or traffic spike early can prevent bigger problems. For targeted investigation the guide demonstrates using grep to pull out specific IPs, URLs, or error patterns, piping results into less for easier reading, and explains how archived logs can be read on the fly with zcat after rotation. Finally it cautions against installing heavy tools like multitail or lnav when simple utilities are sufficient, ending with a real‑world anecdote that illustrates how a single log line uncovered a 500 error loop.
The guide explains how to move from the older Debian‑provided Nginx package to the newer mainline build on both Debian 10 and 11, stressing that the stock versions lack recent security patches, performance improvements, and modern modules. It lists the key benefits of the mainline release—such as native HTTP/2 and QUIC support, an updated reverse‑proxy module, and faster bug fixes—and illustrates with a real‑world TLS handshake speed improvement after upgrading. The steps themselves are straightforward: add the official Nginx repository to /etc/apt/sources.list.d, import and trust the GPG key, run apt update, install nginx, and check that the output shows “mainline”. Finally, the article covers useful post‑installation tweaks like pinning the package for automatic security updates, removing the default site configuration to avoid conflicts, and restarting the service to confirm it is running.
