This guide walks you through installing LimeSurvey on Ubuntu 20.04 by assembling a minimal LAMP stack, hardening PHP, creating a dedicated database user, downloading the latest release, setting correct ownerships, configuring an Apache virtual host, and launching the web installer. It starts with updating the system and installing only the essential packages—Apache2, PHP 7.4, MariaDB server, and unzip—and then tweaks memory limits and execution time to avoid install hangs. After pulling the ZIP archive into /var/www/html, the instructions rename it, grant www‑data ownership, set directory and file permissions, and enable a new virtual host that points to the survey folder before reloading Apache. Finally, you open a browser to the local hostname, run through the wizard, and if all steps were followed correctly you’ll see the “LimeSurvey – Welcome!” screen; the article also highlights common pitfalls such as using an unsupported PHP version or forgetting write permissions on cache directories.

The article is a quick reference for getting an iRedMail mail server up and running on a brand‑new CentOS 8 box without unnecessary detours. It starts with a list of prerequisites such as a clean OS installation, root or sudo privileges, a static IP, and properly configured DNS records before explaining how to temporarily turn off SELinux and open the required SMTP, IMAP, and POP3 ports in the firewall. The guide then walks through installing MariaDB 10.4, creating a dedicated iRedMail database user with full privileges, and running the official installer script that sets up Postfix, Dovecot, Roundcube, and optional Let’s Encrypt certificates. Finally it covers post‑installation tweaks like replacing self‑signed TLS certs, adding DKIM, SPF, and DMARC DNS records, troubleshooting common issues such as relaying errors or queue stalls, and testing the setup with a command‑line mail send to confirm proper delivery.
The article guides readers through adding Jenkins’ official repository to Ubuntu, installing a recent Java runtime like OpenJDK 17, and then pulling and configuring the Jenkins service with systemd. It explains how to start the server, enable it to run on boot, retrieve the initial admin password from a protected file, and complete the web based wizard that installs recommended plugins and creates an administrator account. Practical advice addresses common pitfalls such as firewall blocks on port 8080, Java version mismatches, and stale packages that can keep Jenkins from launching. The writer also shares a personal tweak about switching to the official repository to resolve plugin compatibility problems on older machines, ending with encouragement to explore pipelines and automate tests.
On a fresh CentOS 8 box the guide walks you through adding Docker’s official repository, installing Docker CE with its dependencies, and enabling the service so that it starts at boot. After verifying Docker works by running hello‑world, the tutorial pulls the latest Portainer image, creates a dedicated volume for persistent configuration, and launches the container with port forwarding to 9000 over HTTPS. It then reminds you to open https://:9000 in a browser, create an admin user, and connect to your local Docker host while covering common pitfalls such as SELinux permissions and firewalld rules that might block Portainer’s socket or web interface. Finally the author explains why Portainer offers a lightweight, visual alternative for managing containers on multiple hosts compared to command‑line tools.
