Raspberry Pi cloud disk internal network penetration and expansion

1. External network access

First download the peanut shell software to your computer, then register an account to receive a free domain name, open the intranet penetration service (you should pay 6 yuan now to activate), after activation, open the intranet penetration to add the mapping, add according to the picture below

After adding the mapping, we will start to change the trust domain of the cloud disk. Follow the steps below on the Raspberry Pi terminal

cd /var/www/html/owncloud

sudo nano config/config.php

Change the original ip of the Raspberry Pi in the brackets to your Internet access address

After the change, you can test it on your phone

Enter "external network access address/owncloud" in the browser to enter your cloud disk

15239m665v.51mypc.cn:19358/owncloud

2. Expansion

1. First format your hard disk/U disk to ext4 format

Use MiniTool software, send "M" to WeChat public account to get

Find the hard disk/U disk you want to mount, click delete above

2. Mount the hard disk/U disk

Insert it into the Raspberry Pi and check the status with the following command

 sudo fdisk -l 

We mount it on /disk under /home

cd /home

sudo mkdir disk
sudo mount -o uid=pi,gid=pi /dev/sda1 /home/disk
sudo nano /etc/fstab

Add the following piece of code at the end

/dev/sda1 /home/disk ext4 defaults 0 0

3. After the mounting is complete, copy the /var/www/html/owncloud/data folder to /home/disk

(If you are not familiar with the command here, you can use the VNC graphical interface to complete it)
First give permission

sudo chmod 777 /var/www/html/owncloud/data

sudo chmod 777 /home/disk

sudo chmod 777 /var/www/html/owncloud/data/owncloud.log

Next, go to the graphical interface and copy the data folder to /home/disk

After copying, give the user permission for the path

sudo chown -R www-data:www-data /home/disk/data

4. Modify owncloud settings

cd /var/www/html/owncloud/config

sudo nano config.php

After opening the file, change the /var/www/html/owncloud/data inside to /home/disk/data

Save and exit

Successful expansion

Just upload a picture, you can see it is stored in /home/disk/data
