Once the base is ready, I’ll count on you to: • install the correct Node, React build tools, and the matching .NET runtime • wire the SQL engine (SQL Server or MariaDB—advise me on the pros and cons for this size app) • configure Nginx or Apache as a reverse proxy with HTTPS, automatic renewals, and sensible caching • set up environment variables outside the repo, log rotation, and a simple backup routine • give me a one-command (or CI/CD) deployment path so I can push future updates without touching the server manually The job is done when: 1.

My AlmaLinux 8.10 server is running Plesk, Juggernaut Firewall, Apache, PHP-FPM, MariaDB and sits behind Cloudflare. After a recent DDoS wave I tightened the Juggernaut Firewall rules following AI-generated advice and, ever since, the main website only returns blank pages while every other hosted or backup domain works fine. Web pages are the only service failing; mail and databases stay responsive. I already restarted services and even rebooted the node, yet the symptom persists. I need an expert who routinely works with Plesk and Juggernaut Firewall to: • Dive into Apache, PHP-FPM and MariaDB logs to pinpoint the root cause of the blank-page delivery. • Audit the latest Juggernaut Firewall changes I applied and reverse or fine-tune anything that is blocking le...

...run flawlessly through Apache, but after some recent changes it now shows the default Apache2 page on http and refuses the ssl connection on https. The project code and its virtual-environment are still intact; only the web server seems to have slipped. I’m convinced the root cause sits inside the Apache configuration, yet I can’t pinpoint which piece—virtual-host blocks, WSGI hook-up, or a stray SSL tweak—went out of line. I may also have forgotten whether any custom directives were added earlier. What I need from you • Inspect the current Apache setup, locate the misconfiguration, and repair it so the site renders over both http and https. • Ensure the existing SSL certificate (Let’s Encrypt) or a freshly issued one is...

My application is ready for a dedicated round of performance validation and I need a specialist who can concentrate exclusively on load testing. The aim is to simulate realistic user traffic, capture solid data on response time and throughput, and translate that data into clear, actionable recommendations for tuning the system. You are free to work with the tool-set you know best—Apache JMeter, Gatling, LoadRunner, or any similar platform—as long as the results are repeatable and easy for my team to verify later. We can iterate together on scenario design, but I expect guidance on industry-standard workloads and step-up patterns so the numbers we collect truly reflect production behaviour. Deliverables • Load-test plan outlining scenarios, user counts, and ramp-...

I need an experienced Linux-Apache engineer to walk me through creating a clean, future-proof structure on my Ubuntu server so it can host four WordPress sites now and scale to eight without any one client seeing another’s data. During our 1 to 1.5 hour random weekday sessions (Starting 6pm EST Brisbane Australia) we will cover: • A simple “umbrella” landing layer that routes each owner to only their site while keeping URLs tidy. • Cloning my current (offline, re-branding) WordPress install into four separate virtual hosts. Adding domains and routes as completed and purchased by me externally as we go. There should be an admin page to transfer ownership of individual sites and then they can look after it. This admin page is the "Umbrella&qu...

My site sits on a Linux VPS running Apache 2.4 and what used to be instant page loads have turned into frequent timeouts. The first byte often takes ages, sometimes ending in a 504, yet once the connection finally starts static files stream normally. Something in the stack is stalling Apache and I need it fixed without disrupting live traffic. You’ll receive root SSH access and may use whatever diagnostic tools you trust—top, htop, mod_status, strace, iotop, sar, you name it—as long as each action is noted so I can follow the trail later. Feel free to tune prefork/event settings, adjust keep-alive, chase down misbehaving PHP-FPM pools, cron jobs, database locks or anything else you discover. Deliverables • Clear diagnosis explaining the root cause o...

...spans CentOS 6 and 7 with Apache web services, Sendmail + Dovecot mail delivery, BIND-named for DNS, Mailman mailing lists, DKIM/SPF records, MX routing, virtusertable aliases, and a range of hand-tuned legacy scripts that keep it all working together. The web, mail, and DNS layers (Apache, Sendmail, Dovecot) all carry bespoke configuration tweaks that must be kept intact. I have detailed documentation for these customisations, including conf file excerpts, directory layouts, and notes on historical work-arounds, so you will not be reverse-engineering them from scratch. Your mission is to recreate the environment on the new VPS reseller platform, validate service parity, and cut the final switchover with minimal downtime. Key expectations • Clean migration of A...

My forum has suddenly stopped loading c...htaccess file. Nothing in that file has been touched recently, yet Apache now refuses to serve the site as expected. I need someone who knows mod_rewrite, directory and file-level directives, and typical vHost interactions inside out. Your job is to: • Inspect the current .htaccess, identify the mis-configuration or conflicting rule • Adjust or rebuild the file so every forum page loads without 4xx/5xx errors • Provide a short rundown of what was wrong and the exact lines you added, removed, or reordered Once you confirm the fix on your end, I’ll clear the server cache and test again. Payment will be released when the forum home page and sub-threads load cleanly over both www and non-www, and no rewrite loops show...

I’m running a site on Apache with PHP 8.x and have hit a wall with what appears to be a pure code-syntax problem. The server itself is behaving, but one or more scripts now throw fatal errors after the recent version bump. I need someone who can drop in, identify the faulty lines, and patch them so everything runs cleanly again without breaking existing functionality. You should already feel comfortable combing through modern PHP 8 features (typed properties, union types, match expressions, etc.) and spotting the classic gotchas that trip an upgrade. When you reply, focus on the relevant experience you have fixing syntax or backward-compatibility issues; no long proposals—just a quick note on similar fixes you’ve completed is perfect. Deliverables I expect: &bull...

I need WHM installed on an Ubuntu-based VPS. Root SSH access is ready, and the cPanel/WHM license is already active, so there’s no procurement step—just a clean, reliable install. The job is straightforward: set up the latest stable WHM release, run any routine post-install scripts, and confirm that basic services (Apache, MySQL/MariaDB, Exim, DNS) start without errors. Standard configuration is all I’m after; no custom tweaks or extra hardening beyond what the installer applies by default. Please plan to: • Complete the installation in one session so downtime is minimal. • Hand over the WHM login URL, root credentials, and the installation log for my records. • Verify access to the WHM dashboard and that service status shows “green&rdqu...

Our WordPress site is buckling whenever wp-admin/ fires during routine back-end work. CPU load jumps from its normal sub-20 % to a sustained 100 %, bringing everything else to a crawl. I’m on Cloudways (Nginx + Varnish + Apache stack) with the native Breeze cache and Redis Object Cache already active, yet these AJAX calls bypass every layer of caching. Here’s what I need from you: • Identify the root cause of the excessive admin-ajax requests that appear mainly while I’m carrying out administrative tasks. • Implement code-level or configuration fixes that stop the spike and keep average server load consistently below 20 % during the same activities. • Tune the stack so GT-metrix and Google PageSpeed scores reflect the back-end improvements&mdas...

I’m ready to retire our self-managed Apache Kafka dev cluster and move everything onto AWS Managed Streaming for Kafka. The driving factor is cost-efficiency, but I must not sacrifice performance or reliability along the way. Automatic scaling and high availability are therefore non-negotiable parts of the build. Here is what I need from you: • Plan and provision a new AWS MSK environment that supports automatic scaling and HA out of the box. • Migrate topics, configurations, and data streams from the existing Kafka nodes with minimal downtime. • Tune broker, partition, and storage settings so we gain the cost savings MSK promises without hitting performance bottlenecks later. • Hand over clear documentation (or Terraform/CloudFormation templates if...

...services: an SVN server, Apache, and an MQTT broker. SVN is the priority. I will supply notes that describe the custom repository structure I want as well as the user-authentication rules. You will translate those notes into a working configuration, test that check-ins/outs succeed, and make sure credentials are enforced exactly as specified. Apache only needs a standard install for now—just enough to host basic web content and, if you choose, to act as the front end for SVN via mod_dav_svn. The MQTT broker can be Mosquitto; a stock setup on the default ports is fine so long as it starts automatically and is reachable from the outside once the firewall rules are in place. Deliverables • A running Google VM on Ubuntu 22.04 with SVN (custom repo structure + u...
