Installing LEMP & NextCloud on a Raspberry Pi running Ubuntu 16.04

This is a thrown tutorial mostly from here and here, I have been piecing together from tutorials about how to do this so I thought I'd share the steps I took to install NextCloud.

Section 1: First get your Rasberry Pi setup with ssh and take it through the inital setup steps until you have ssh setup and connected. There are plenty of websites that have that tutorial so go ahead and find one.

Section 2: Start by signing up for a dynamic DNS service like NoIP. If you use NoIP go through their documentation for setting up their app on linux. Also make sure you forward ports 80 and 443 on your router.

Section 3: Setup & Install dependencies

Download & Install NextCloud

wget https://download.nextcloud.com/server/releases/latest.zip
sudo apt install unzip
unzip nextcloud-latest.zip

Lets move the NextCloud directory to the doc root of Nginx:

sudo mv nextcloud /usr/share/nginx/

Give it permissions like so:

sudo chown www-data:www-data /usr/share/nginx/nextcloud/ -R

We are going to start installing some of the dependencies. Start by updating

sudo apt-get update
sudo apt-get upgrade
Install and start Nginx, and have it start on boot

sudo systemctl enable nginx
sudo systemctl start nginx
sudo systemctl enable nginx

Here are more commands if you need to deal with Nginx:
Check if Nginx is running
```
 systemctl status nginx
```
Stop then start Nginx
```
 sudo systemctl restart nginx
```
Start nginx at boot
```
 sudo systemctl enable nginx
```

Configure MariaDB
Install, start and have MariaDB start on boot:

sudo apt install mariadb-server mariadb-client
sudo systemctl start mysql
sudo systemctl enable mysql

When you are done with the install you still need to run the SQL startup scrypt:

sudo /usr/bin/mysql_secure_installation

mysql -u root -p

Create a database for NextCloud:

create database nextcloud;

Create a user and a password for that user:

create user nextclouduser@localhost identified by 'your-password';

Grand that user privileges:

grant all privileges on nextcloud.* to nextclouduser@localhost identified by 'your-password';

Flush privileges and exit:

  flush privileges;
  exit;

Install php7 and extensions

sudo apt install php7.0-fpm php7.0-mbstring php7.0-xml php7.0-mysql php7.0-common php7.0-gd php7.0-json php7.0-cli php7.0-curl

Edit your php config

 sudo nano /etc/php/7.0/fpm/pool.d/www.conf

Find the line that starts with listen and make it look like this:

;listen = 127.0.0.1:9000
listen = /var/run/php5-fpm.sock

Reload php

 sudo service php7.0-fpm reload

Create an Nginx config file in /etc/nginx/conf.d/

   sudo nano /etc/nginx/conf.d/nextcloud.conf

Paste this as your config. Replace your domain with your noip domain

server {
    listen 80;
    server_name nextcloud.your-domain.com;

    # Add headers to serve security related headers
    add_header X-Content-Type-Options nosniff;

        # Optional: Don't log access to other assets
        access_log off;
   }
}

Save and close the file. Test Nginx and reload. If this passes you should be able to

sudo nginx -t
sudo systemctl reload nginx

Download & install Let's Encrypt:

cd 
git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt
./letsencrypt-auto --help

Switch to the directory and replace webroot and domain name:

cd ~
cd letsencrypt/
./letsencrypt-auto certonly --nginx -w root /usr/share/nginx/nextcloud/ -d your-domain.name

If that was sucessful, then we need to edit the Nginx config again:

sudo nano /etc/nginx/conf.d/nextcloud.conf

Change the top of the file to be this, overrite the old listen 80;:

listen 443 ssl;

Add these lines below they are to verify Let's Encrypt so you can use ssl. Replace the domain with yours:

ssl_certificate /etc/letsencrypt/live/your-domain.com/cert.pem;
    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;

Then add this to the top of the file, not inside your other server declaration:

server {
  listen 80;
  server_name mre.sytes.net;
  return 301 https://$server_name$request_uri;  # enforce https
}

Test Nginx and reload. If this passes you should be able to navigate to your-domain.com/nextcloud in a browser:

sudo nginx -t
sudo systemctl reload nginx

Make Nextclouds data directory and give it permission

sudo mkdir /usr/share/nginx/nextcloud-data
sudo chown www-data:www-data /usr/share/nginx/nextcloud-data -R

Now if it shows the web login then it was a sucess! If you have an external hhd you want to add here's how. Use this to find your external hard drives UUID which is associated with a /sda1 drive:

ls -l /dev/disk/by-uuid/

Mount the drive:

sudo mount -t ntfs-3g -o uid=1000,gid=1000,umask=007 /dev/sda1 /media/nextcloud

Backup and open fstab:

sudo cp /etc/fstab /etc/fstab.backup
sudo nano /etc/fstab

Add this line:

UUID=[Your UUID] /media/nextcloud ntfs-3g uid=1000,gid=1000,umask=007 0 0

Now that should be it, your nextcloud installation should work and after you install the external files app you should be able to add your drive through the web interface.
