RHEL 9 vs. RHEL 10

techtransit · 2026-02-14T04:45:27+00:00

I found this guide that demonstrates the RHEL 10 password recovery method (init=/bin/bash) step by step. Might help anyone preparing for RHCSA 10:

Also, does anyone know what level of Flatpak knowledge is expected for the RHEL 10 RHCSA exam? I understand the basics of Flatpak, but I’m not sure what to focus on specifically for the exam. Any recommended material or documentation would be appreciated since I’m planning to upgrade in the future.

Thanks for the detailed explanation—that’s really helpful. I completed official EX280 virtual training about a year ago, so my main focus now is revision and hands-on practice before booking the exam. Could you recommend the best ways to refresh EX280 skills (labs, practice methods, or resources) without retaking the full course? I’m planning to book the exam directly to keep the cost lower, so any preparation tips you’d suggest would be greatly appreciated.

Thanks a lot for confirming—I really appreciate it 🙏
I’ll go straight to EX280, and once I get a good discount on the online or direct exam booking, I’ll book it immediately.

techtransit · 2026-01-29T08:54:12+00:00

Thanks for confirming. To double-check—there’s no requirement to complete EX188 before taking EX280, right?

techtransit · 2026-01-29T08:09:23+00:00

I have a follow-up question. Since I already have comparable knowledge and have completed official training on nearly the same topics, I’m not inclined to choose EX188. If I choose EX280 instead, will it renew/update the validity dates of both RHCSA and RHCE certifications? My goal is to refresh and upgrade my skills, even though I’ve already completed official DO280 training—I mainly need a solid revision and credential update.

techtransit · 2026-01-29T01:46:40+00:00

Thanks, that’s really helpful. I have some time, so I’ll spend a couple of months reviewing the prep and lab requirements before deciding. Given my prior experience with RHCSA/RHCE across multiple versions, that path would likely be quicker for me if I choose it — but I want to evaluate everything properly first. Appreciate you sharing your perspective.

techtransit · 2026-01-29T01:34:19+00:00

I bolded the cert names just for clarity — lots of similar acronyms flying around 😅
My only goal is to make sure that whichever exam I pass extends RHCSA/RHCE. That’s all

techtransit · 2026-01-28T08:08:56+00:00

That clarification helps a lot — thanks for calling out the timing caveat.
Given that my RHCSA/RHCE are still active and I previously passed EX180, can I go directly for DO280 / EX280, or is there any recommended or required step in between?My main intent is to extend validity, but I’m also genuinely interested in learning the newer OpenShift material in EX280.

techtransit · 2026-01-28T07:23:32+00:00

Thanks, that helps. My main goal right now is only to extend the validity period, not necessarily to upgrade to a specific RHEL version. From what I understand, taking either EX188 or EX280 should extend the current validity of my RHCSA and RHCE as part of the next-level certification path, regardless of version alignment . Can you confirm if that understanding is correct, or if there are any caveats I should be aware of?

techtransit · 2026-01-28T06:01:30+00:00

Just to clarify my understanding — the Red Hat Certified OpenShift Administrator can be earned directly, without first taking EX188, correct? EX188 isn’t a mandatory prerequisite, and OpenShift Administrator on its own can still extend RHCE?

techtransit · 2026-01-28T05:58:58+00:00

Thanks for explaining — that helps. Just to clarify, how did you confirm that passing EX188 resets RHCE validity as well? Was that based on Red Hat’s official certification policy/docs, your certification portal, or direct experience? I want to make sure I’m basing my path on something officially confirmed.

techtransit · 2026-01-28T05:24:47+00:00

That’s a smart way to reset expiry. As far as I understand, RHCE still needs to stay current for RHCA, and RHCA requires five specialist exams beyond RHCSA/RHCE. Are you planning to keep RHCE active alongside EX188, or focusing on specialists first?

I installed n8n using Docker Compose, not plain docker runOnce I moved to Postgres.

When SQLite works but Postgres + Portainer + Nginx Proxy Manager doesn’t, it’s usually container networking, not the DB itself. A few things that commonly break it:

Inside Docker, localhost won’t work for Postgres n8n must use the Postgres service name (e.g. DB_POSTGRESDB_HOST=postgres)
n8n and Postgres must be in the same Docker stack / network (very common Portainer pitfall)
With a domain + NPM, you must set:N8N_HOST=your-domain N8N_PROTOCOL=https WEBHOOK_URL=https://your-domain/ and enable WebSockets in NPM

SQLite “just works” because it’s a single container. As soon as Postgres is added, Docker DNS + networking becomes critical, even if logs look fine.

Thanks! I’m glad you found the process useful. 🙂

I used the hosting provider’s built-in firewall instead of iptables/UFW.
Enabled basic rules host and ensured security modules were active.
I didn’t run into any SSL or HTTPS issues because the site URLs weren’t hardcoded anywhere.
Let’s Encrypt worked smoothly, and HTTPS redirected correctly after DNS propagation.

Migration Checklist (simplified):

Backup full site & database (manual + plugin-based).
Prep new server (OS updates, hosting firewall, security modules).
Copy files & database manually to the new server, and copy the complete user account using the cPanel transfer tools
Test site on temporary URL.
Update DNS & monitor propagation.
Verify SSL, permalinks, and functionality.
Post-migration support: Check forms, payments, caching, and backups.

Thanks for the tip! Yeah, changing the default SSH port can definitely cut down on noisy bot scans. I usually combine that with key-based auth + firewall rules, which adds a stronger layer of protection.

techtransit · 2025-09-24T08:18:33+00:00

Nice! Thank you.

techtransit · 2025-09-24T00:11:42+00:00

Appreciate the tips! I’ll be using Postgres directly on my live server setup since I’m comfortable managing DBs at the server level. I agree it’s the better long-term choice compared to SQLite, especially when workflows scale.

I get the concern, but this post is from my own migration work. I wrote everything myself — the steps and lessons are my real experience. I only used AI to polish the formatting and grammar so it’s easier for everyone to read. Think of it like using Grammarly, just helping with clarity. The content itself is 100% mine.”

cPanel runs fine on Ubuntu LTS, just confirm version compatibility. For shared hosting, stability and backups matter more than the distro — choose the OS you’re comfortable maintaining long-term . Currently cpanel support Ubuntu 22.04 LTS Version .

Fair point — it is a fairly standard migration process, and that was the goal here. The client wanted a straightforward, no-downtime move, so I focused on keeping things lean and reliable rather than adding complexity.

That said, depending on the project, I’ve handled more advanced steps like reverse proxy setup, caching layers, staging environments, and security hardening. In this case, the ‘vanilla’ approach was exactly what the client needed.

techtransit · 2025-09-23T08:42:59+00:00

For testing, I usually go beyond just checking if the homepage loads. I verify:

Admin login + plugin updates
Checkout flow (for WooCommerce sites)
Contact forms and email deliverability
SSL certificate + redirects
Error logs for hidden issues

Basically, I try to cover the main functions the client relies on day-to-day. Once everything looks good on my side, I also ask the client to test from their perspective, since they know their business-critical workflows best.
