Mixpost

[privsec]

If you install a fresh instance, do you need to worry about the upgrade? Or does this upgrade process have to be followed for each subsequent update?

[humptydumpty]

@privsec a fresh install will get you to v1 but you might still encounter an error when running php artisan migrate. In that case, follow my post above the upgrade guide to get that sorted out. I think we’ll encounter the same issues when upgrading in the future because the file ownership defaults to root and not www-data for newly added files, so the upgrade guide should apply to future updates.

@humptydumpty Ayeee! GG +1
Well done. I have not messed with my instance recently - my Horizon would eventually kill or become inactive somehow and I would have to manually restart.

I was planning on a rebuild and more TS so i will test your steps and report back

[humptydumpty]

@plusone-nick I just checked Horizon and it's still running on my instance. I linked Twitter yesterday and made two posts which worked as intended. I think we got a working and stable guide going for Mixpost! The only issue left is figuring out the Horizon magic. How is it alive?! It feels like we created Frankenstein and now trying to see what makes him tick

[humptydumpty]

@girish We sorted out all Mixpost installation errors but the Horizon mystery remains. Dima has no clue how Horizon is staying alive without Supervisor. Any thoughts?

[privsec]

@humptydumpty and @plusone-nick
Do we need to have Horizon stay alive? Is there a way we can confirm it is up, and if it is not working, what do you do?

[humptydumpty]

@privsec Horizon has to stay alive. It's a must.

Go to your domain.com/mixpost/admin/system/status page and it should all be green like this.

Also, when you ran the command: php artisan horizon

If you wait a few seconds, you should see it report back something similar to a ping test:

bla bla bla.... 15ms
bla bla bla... 8ms

Otherwise, it will say KILLED instead.

If its not working, then you need to redo the installation and apply the "fix" that I posted in comment #83

[privsec]

Ol, so do the steps listed in comment #49 and then comment #83

Would one need to do these same steps every time an upgrade is needed?

How do you retain customers account logins when doing an upgrade?

[humptydumpty]

@privsec Please keep in mind, I just installed it too and I haven't used the app before, so I'm in the same boat as you. However, since we worked out all the errors, the upgrade path should keep all existing posts/users/media/etc. intact.

Start with Nick's installation guide (#49) (skip step 10; somehow the app works without supervisor) and apply the fixes in #83 to get rid of the errors during the outlined steps. Yes, I believe we will have to do the fixes for each upgrade since any new files that get added by the upgrade will default to root ownership which need to be changed to www-data.

My suggestion is to try to install it the first time while keeping in mind that it's a test run just to familiarize yourself with the process. Then, you'll know when to apply the fixes during the intial installation. A cool thing you can do here is to create a backup of the fresh LAMP that you can restore to. If you delete the app and reinstall it, then all the credentials (mysql, phpmyadmin, etc.) will change.

One thing that wasn't mentioned yet, during the installation, you'll be asked "do you want to save these credentials". Say Yes!

I feel comfortable enough to start using the app for my own use. I wouldn't dare give it out to paid clients since it's not a packaged app and Horizon is working automagically but no one knows how because it shouldn't be able to stay alive! With that said, Cloudron backups work and the app itself is stable enough for production use.

[humptydumpty]

@privsec I just realized my mistake. For the initial installation follow #49 (skip step 10; somehow the app works without supervisor) and apply the fixes in #83 to get rid of the errors during the outlined steps.

In the future when you need to upgrade from v1.0 to v1.X, follow the upgrade guide in comment #84 and apply the fixes in comment #83. If you do #49 again, user data won't transfer over.

[privsec]

Ahh, awesome, ok. Thank you

[girish]

@humptydumpty interesting. LAMP app has no special code to run horizon in the background. There must be something else running it. Have you tried to use ps to figure out what the parent process of horizon is?

[humptydumpty]

@girish I ran ps aux (had to look that up, I love that you're mistaking my copy/paste skills with actual coding knowledge )

@humptydumpty Could it be that you started php artisan horizon manually on a web terminal ? Have you tested that it starts up automatically after restarting the app ? (which kills all the existing web terminal sessions).

[humptydumpty]

@girish You're right, after a restart Horizon is inactive. Can this be turned on automatically via a cron like you suggested before? If so, what code should I be using?

[girish]

@humptydumpty yes, correct, you can just put it in the app's cron . Alternately, the LAMP app supports a startup script - https://docs.cloudron.io/apps/lamp/#custom-startup-script .

[humptydumpty]

App won't start. I think I know why its because the php artisan horizon has to be cd'd to /app/data/mixpost-pro-team-app/ first. How do you enter that in run.sh? startup script didn't work.

After much trial and error, I got the cron method to start horizon automatically after I remembered the @service cron Girish mentioned in an earlier post.

@service cd /app/data/mixpost-pro-team-app && php artisan horizon
* * * * * cd /app/data/mixpost-pro-team-app && php artisan schedule:run >> /app/data/null 2>&1

@plusone-nick add this cron to your install guide

[humptydumpty]

I updated from Mixpost Pro v.1.0.0 to v.1.2.0 using the official Mixpost update guide. But you need to do one thing beforehand, and another at the end to complete the steps on Cloudron.

Step 1: navigate to the mixpost folder before starting the update process

cd /app/data/mixpost-pro-team-app/

Step 2: follow update guide https://docs.inovector.com/books/mixpost-pro/page/in-your-standalone-or-laravel-app

Step 3: finish it off by running

 php artisan horizon

Done.

[humptydumpty]

Starting to hit storage issues. I received a backup failed notification. The app size was around 100MB for a fresh install. Now it's 3.98 GB! I'm not really using the app yet or uploading any media so the increase must be from the last update I did (v1.0 to v1.2).

Edit: The culprit is the log file located at /mixpost-pro-team-app/storage/logs/laravel.log (in my case it grew to over 5GB!). It had a lot of Redis references. The app's Redis is green in services and is using around 1/3 of the allocated 150MB so nothing out of the ordinary. The values in the .env file match what's in the credentials.txt file so that's good too. I'll update the post if Dima finds the root cause.

a few lines of the laravel.log file: https://pastebin.com/bkWK1LGA

[girish]

@humptydumpty maybe you can symlink that file to somewhere in /run so that it is not part of the backup.
