Need help installing on Digital Ocean

uing

After spending an entire day trying to install Flarum onto my regular hosting service without success (AllowOverride was the problem), I made the switch to Digital Ocean with the hope of finally running Flarum. However I keep running into problems. Here are my steps:

Creating a new Droplet with LAMP 16.04 (from the one-click apps menu)
Adding a new user (following this guide: https://www.digitalocean.com/community/tutorials/how-to-add-and-delete-users-on-ubuntu-16-04)
mysql secure intallation (sudo mysql_secure_installation)
sudo apt-get install curl php-cli php-mbstring git unzip
Since I don't know which method of installing curl is correct, I've tried this also: apt-get install php7.0-curl
Installing composer:
- curl -sS https://getcomposer.org/installer -o composer-setup.php
- sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer
Installing Flarum:
- cd /var/www/html
- composer create-project flarum/flarum . --stability=beta

If I try this with my new user account this happens:
Cannot create cache directory /home/uing/.composer/cache/repo/https---packagist .org/, or directory is not writable. Proceeding without cache
Installing flarum/flarum (v0.1.0-beta.6)

If I try this as root (which I should not do...) I get this error:

What am I doing wrong?

webeindustry

Do sudo apt-get install php-xml
Clear the directory & reinstall as root.

Thanks for the reply. Now I get the following error:

uing I'd use a 1gb droplet. You're probably using a 512mb one?

uing

luceos that is correct. Let me give it a try

uing

Ok, so I created a new droplet with 1gb and repeated all the steps I mentioned above.
I am logged in with my new user account. When I try to install Flarum with the following command:
composer create-project flarum/flarum . --stability=beta
I get this error even though the folder /var/www/html/ is empty:

Failed to download flarum/flarum from dist: Could not delete ./:
Now trying to download from source
- Installing flarum/flarum (v0.1.0-beta.6) Cloning 0c975a7f10 from cache

[RuntimeException]
Could not delete ./:

then I tried the same command but with sudo, but it gives me the same error as in my first post:
Your requirements could not be resolved to an installable set of packages etc.

did the sudo apt-get install php-xml again. Now I get:
[InvalidArgumentException]
Project directory ./ is not empty.

When I connect with Filezilla and check the folder, it is empty!? What is going on?

luceos

uing delete and re-create the directory, there are hidden files. See them using:

ls -la

uing

luceos thanks, I deleted the folder and recreated it but still get this message:

[RuntimeException]
Could not delete ./:

uing

Ok, so I got around it by using sudo chmod 775 /var/www/html

but now after the installation is complete and I refresh my browser I get: 500 Internal Server Error

luceos

uing enable debug in your config.php and see if any errors show up in the log files of your webserver and php.

uing

luceos How do I enable debugging? and how can I view the results?

But am I doing something wrong during installation? I have been deleting/creating droplets all day and I can reproduce this error every time. So there must be something.

Though I do have a few questions:
1. when I first connect as root and create a new user, should I continue installing as root or switch to the new user?
2. after I create the mysql databse "flarum" the guide suggest I continue with:
GRANT ALL PRIVILEGES ON flarum.* TO 'flarum'@'localhost' IDENTIFIED BY 'password';
Do I enter a new password or do I use the password created with the secure mysql installation?

uing

Another try: new droplet and followed this guide step by step (https://discuss.flarum.org/d/1951-a-flarum-installation-guide-for-dummies-and-the-truly-clueless)

As soon as I try to install Flarum i get:
[InvalidArgumentException]
Project directory ./ is not empty.

Deleting and re-creating the html-folder doesn't change anything.

This is by far the most difficult forum to install ? Been trying for 2 days now. It's giving me a headache

@uing

I would recommend starting from scratch.

Get a ssh login to your host.

Run webeindustries install script:
https://raw.githubusercontent.com/webeindustry/flarumvpsinstallscript/patch-1/script

Something like this:

ssh ubuntu@yourhost
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get install wget
wget https://raw.githubusercontent.com/webeindustry/flarumvpsinstallscript/patch-1/script
sudo chmod +x script
sudo ./script

This install script will walk you through the installation. Im all for troubleshooting but sometimes it best to just use what works.

Enable Debug:

sudo nano /var/www/yoursite/config.php

<?php return array (
'debug' => true,

Yours will no doubt show: false,

You might also want to review:

Stay calm, and Flarum on.

uing

0E800 Thanks a lot! The picture is spot on. I ran the script on a clean droplet and everything went smoothly, yea! But how do I access flarum? When I put in the droplets IP address I get a to a landing page from nginx: If you see this page, the nginx web server is successfully installed and working. Further configuration is required.

Edit: I installed another instance. This time when asked for the url, I entered "html". But after the installation is finished and I access my droplet in the browser by entering the IP address I get the following: 403 Forbidden

What is the output of:

sudo cat /etc/nginx/sites-enabled/yoursitename

What is the location of your site?
/var/www/yoursite?

0E800

uing
Also try clearing your browser cache, ctrl_f5.
The website your seeing is showing /var/www/html but we want it to show /var/www/cyc

Looks like everything is good there.
I had the same issue but not sure what I did to make it work.

Try rebooting your host and see if that helps. What is your site address? I can try testing.

uing

0E800 Thanks for helping out. I tried refreshing, but it still shows the "welcome to nginx".

how do I point to the other folder?

0E800

uing
Solution:

sudo nano /etc/nginx/sites-enabled/cyc

Change:

server_name cyc;

To:

server_name yourserversipaddress;

Then restart nginx or reboot the host.

When you end up registering a domain name you will need to change it to that name.

I stood up a AMAZON EC2 instance to recreate your steps. Thats how I was able to troubleshoot as Amazon provides only an IP.

You may now proceed to flarum on.

uing

0E800 you're the man! Thanks a lot for guiding me through this!
