Installing ArangoDB on RHEL and CentOS requires adding the official signed repository, pulling the server and client packages with YUM or DNF, tweaking SELinux and firewall rules, and enabling the systemd unit that ships with the installation. The tutorial guides you through each prerequisite check—clean machine, sufficient RAM, fully patched kernel—and shows how to adjust data directories and expose the default ports 8529 for HTTP and 8530 for AQL. After starting the service, you can confirm it’s running by querying the local API endpoint or by creating a root user if you plan to expose the database beyond localhost. In short, the article gives sysadmins and developers a practical, step‑by‑step path to get a fully functional ArangoDB instance up and ready for use on their Linux hosts.
The article walks you through setting up Artifactory OSS on RHEL 8, CentOS 8 or Rocky Linux 8 by adding JFrog’s official Yum repo, installing a Java 11 runtime, and downloading the RPM directly from that repository.
Before you begin it lists key prerequisites: a 64‑bit host with sudo access, at least four gigabytes of RAM, SSH connectivity, and an early SELinux configuration set to permissive to avoid post‑reboot permission problems.
Once Java is installed, the guide installs the jfrog-artifactory-oss package, places it under /opt/jfrog, tweaks the systemd unit to raise the JVM heap to 2 GB minimum, reloads daemon configurations and then enables the service.
You can verify the installation by checking the service status or visiting http://your-host:8081/artifactory, logging in with admin/password, and referring to /opt/jfrog/artifactory/var/log/server.log if anything goes wrong.

The instructions add the firewall-config package (the GTK front‑end for firewalld) to a fresh Fedora 36 system, first refreshing the system with sudo dnf upgrade --refresh -y and then installing the GUI via sudo dnf install firewall-config -y. After installation you ensure SELinux permits the UI by setting firewalld_gui with sudo setsebool -P firewalld_gui 1, enable and start the firewalld daemon (sudo systemctl enable --now firewalld) if it isn’t already running, and finally launch the graphical tool from the Activities menu or with firewall-config &. The GUI lets you select zones, open ports, and block services visually, and you can keep it synchronized with any command‑line changes by using File → Reload. With these few commands and a couple of clicks you have a fully functional firewall management UI on Fedora 36.
On an Ubuntu 20.04 server with root or sudo rights, the guide walks you through updating packages and installing Apache, PHP, MySQL, Git, and unzip before moving on to configuration. It then shows how to create a dedicated database user, clone YOURLS from GitHub into /var/www, and edit the settings file with your credentials, site URL, and admin login. After enabling mod_rewrite and configuring an Apache virtual host that points to the YOURLS directory, you can launch the admin interface, create a short link, and confirm redirects work. A final tip reminds you to adjust ownership of the YOURLS folder so Apache can write cache files, ensuring smooth operation when extending or using its API.
Enabling mod_rewrite on Rocky 8 or Alma Linux 8 starts by verifying that the module is already loaded, which you can do with `sudo httpd -M | grep rewrite`; if nothing appears, Apache has not activated it yet.
Once confirmed missing, add the line `LoadModule rewrite_module modules/mod_rewrite.so` to `/etc/httpd/conf.modules.d/00-base.conf`, ensuring the module is automatically reloaded whenever the package updates.
If your site relies on `.htaccess` files, edit or create `/etc/httpd/conf.d/allow-override.conf` and insert a ` AllowOverride All ` block so that rewrite rules in those files are respected.
Finally, run `sudo systemctl reload httpd`, then place a simple rule in `/var/www/html/.htaccess`—for example `RewriteEngine On` followed by `RewriteRule ^hello$ welcome.html [L]`—to confirm that the URL rewriting is functioning correctly.

The guide shows how to install a fresh Zulip instance on Debian 11 within an hour, using plain package installs instead of complicated scripts and ending with a simple systemd tweak. It lists the basic prerequisites—a non‑root user with sudo rights, internet access, and a clean Debian installation—then walks through adding the Zulip repository by importing its GPG key and editing the apt sources list. After that it installs the necessary packages such as zulip-server, python3-pip, python3-venv, postgresql, libpq-dev, and nginx, configures PostgreSQL with a dedicated user and database, runs the Zulip setup wizard to create tables and systemd service files, and finally enables and starts those services for verification. Once everything is running you can access the welcome screen locally or secure it with a Let’s Encrypt certificate if you plan to expose the server publicly.
An in‑depth tutorial walks the reader through installing a self‑hosted Firefox Sync server on Debian 11, starting with system updates and user creation before pulling the official binary from GitHub or compiling it from source.
It covers the installation of required libraries like libssl3 and libpq5, setting up PostgreSQL credentials, running migrations, and writing a TOML config that binds to port 443 while deferring TLS handling to Nginx.
Next, the article explains how to configure an Nginx virtual host, obtain Let’s Encrypt certificates with Certbot, reload services, and finally verify the sync functionality from Firefox by adding an account pointing to the new endpoint.
The final sections emphasize troubleshooting common pitfalls such as wrong database URLs or missing Nginx reloads, recommend automating certificate renewal, and suggest additional security hardening steps before deploying in production.
