Recommended MINIMUM system specs: 1 Gigahertz CPU / 512 Megabytes RAM / HIGH QUALITY 32 Gigabyte MicroSD card (running Nginx or Apache headless with PHP v7.2+)
Compatible With Raspberry Pi Zero W
To install / upgrade everything automatically on Ubuntu or Raspberry Pi (an affordable low power single board computer), copy / paste / run the command below in a terminal program (using the 'Terminal' app in the system menu, or over remote SSH), while logged in AS THE USER THAT WILL RUN THE APP (user must have sudo privileges):
Follow the prompts. This automated script gives you the options to: install / uninstall a PHP web server automatically, download / install / configure / uninstall the latest version of the Open Crypto Tracker app automatically, setup a cron job automatically (for price alerts / price charts), and setup SSH (to update / install web site files remotely to the web server via SFTP) automatically.
When the auto-install is completed, it will display addresses / logins to access the app (write these down / save them for future use).
SEE DOCUMENTATION-ETC/RASPBERRY-PI for additional information on securing and setting up Raspberry Pi OS (disabling bluetooth, firewall setup, remote login, hostname, etc).
Your web host must have CURL modules activated on your HTTP server. Most web hosting companies provide this "out-of-the-box" already. This app will detect whether or not CURL is setup on your website server (and also alert you to any other missing required system components / configurations).
WINDOWS 10 USERS WHO ARE USING XAMPP WILL NEED TO ENABLE GD FOR PHP (FOR THE ADMIN LOGIN CAPTCHA SECURITY) BEFORE USING THIS APP. PLEASE SEE THE SCREENSHOT LOCATED AT /DOCUMENTATION-ETC/XAMPP-ENABLE-GD.png FOR A VISUAL ON SETTING THIS UP EASILY.
See "Setting Up Price Charts And Email / Text / Telegram / Alexa Price Alerts", for how to setup a cron job for additional features.
Running price charts or price alerts requires setting up a cron job or scheduled task on the Ubuntu / Raspberry Pi / Windows 10 machine or website server (this is automated for Ubuntu and Raspberry Pi users using the automated FOLIO-INSTALL.bash script / Windows 10 users who run the ADD-WIN10-SCHEDULER-JOB.bat file), otherwise charts / alerts will not work. Also see the related settings in Admin Config for charts / alerts.
Once a cron job is setup, there is no need to keep your PC / Laptop turned on. The price charts and price alerts run automatically from your app server. If you encounter errors or the charts / alerts don't work during setup, check the error logs file at /cache/logs/error.log for errors in your configuration setup. Basic checks are performed and errors are reported there, and on the Settings page.
If you want to take advantage of these cron job based features and more (chart data backups, daily or weekly error log emails / etc), then the file cron.php (located in the primary directory of this app) must be setup as a cron job on your Ubuntu / Raspberry Pi / website server device.
As mentioned previously, if you run the automated setup / install script for Ubuntu or Raspberry Pi devices on home / internal networks, automatic cron job setup is offered as an option during this process. If you are using a full stack website host for hosting a TLD website domain name remotely, consult your web server host's documentation or help desk for their particular method of setting up a cron job.
Note that you should have the cron job run every 5, 10, 15, 20, or 30 minutes 24/7, based on how often you want chart data points / alerts / any other cron based features to run. Setting up the cron job to run every 20 minutes is the RECOMMENDED lowest time interval. IF SET BELOW 20 MINUTES, lite chart disk writes may be excessive for lower end hardware (Raspberry PI MicroSD cards etc). IF SET #VERY LOW# (5 / 10 minutes), the free exchange APIs may throttle / block your data requests temporarily on occasion for requesting data too frequently (negatively affecting your alerts / charts).
FOR WINDOWS 10 USERS, just click / run the file 'ADD-WIN10-SCHEDULER-JOB.bat' found in the main directory of the app, and everything will be automatically setup for you. As long as you login into your Windows account after system startup, the scheduled task will run every 20 minutes until your computer is shut off.
FOR LINUX / MAC USERS, here is an example cron job command line for reference below (NOT including any cron parameters your host interface may require), to setup as the "command" within a cron job. Replace system paths in the example with the correct ones for your server (TIP - A very common path to PHP on a server is /usr/bin/php):
Here is another example of a COMPLETE cron command that can be added by creating the following file (you'll need sudo/root permissions): /etc/cron.d/cryptocoin on a linux-based machine with systemd (to run every 20 minutes 24/7)...play it safe and add a newline after it as well if you install examples like these:
If your system DOES NOT have the directory /etc/cron.d/ on it, then NEARLY the same format (minus the username) can be installed via the legacy 'crontab -e' command (YOU MUST BE logged in as the user you want running the cron job):
Important Cron Job Notes:
MAKE SURE YOU ONLY USE EITHER /etc/cron.d/, or 'crontab -e', NOT BOTH...ANY OLD DUPLICATE CRONTAB ENTRIES WILL RUN YOUR CRON JOB TOO OFTEN. If everything is setup properly, and the cron job still does NOT run, your particular server may require the cron.php file permissions to be set as 'executable' ('755' chmod on unix / linux systems) to allow running it.
Below is an example for editing your assets / markets into the portfolio assets in the file config.php (located in the primary directory of this app), in the PORTFOLIO ASSETS section. It's very quick / easy to do (after you get the hang of it, lol). Also see the text file DOCUMENTATION-ETC/CONFIG-EXAMPLE.txt, for a pre-configured set of default settings and example assets / markets.
Contact any supported exchange's help desk if you are unaware of the correct formatting of the trading pair naming you are adding in the configuration file (examples: Kraken has arbitrary Xs inserted in SOME older pair names, HitBTC sometimes has tether pairing without the "T" in the symbol name).

USAGE (ADDING / UPDATING COINS):
SEE DOCUMENTATION-ETC/CONFIG-EXAMPLE.txt FOR A FULL EXAMPLE OF THE DEFAULT CONFIGURATION (ESPECIALLY IF YOU MESS UP config.php, lol)
If you recently upgraded to a newer version of this app, and layout or features don't work properly anymore, you may need to clear your browser cache (temporary files) and restart you browser / refresh the page afterwards. This will assure your browser is loading any newly-updated layout styling or javascript-based features.
If your problems still persist even after clearing your browser cache (temporary files) and restarting your browser, your config.php setup may be corrupt IF YOU EDITED IT BY HAND. If you did edit it by hand, try backing up you old config.php file, and replacing it with the default config.php file included with the latest release. This will ensure your configuration setup is not corrupt from messed up file formatting.
If none of the above solutions work, your last resort (before contacting me for support) is to wipe out all data in your cache directory folder within the app. THIS WILL ERASE YOUR CHART DATA, SO YOU MAY WANT TO BE SURE YOU HAVE A BACKUP FIRST. After your chart data is backed up, delete the folder named 'cache' in the main directory of this app. Reloading the app web page should re-create the cache folder, with new / clean cache files.
If you are still having issues after trying everything, file an issue here at the github project account, and I will help you troubleshoot the problems: https://github.com/taoteh1221/Open_Crypto_Tracker/issues
If you are sure your username / password / host:port setup are valid, try disabling SMTP email sending by blanking out your username / password / host:port (in the Admin Config COMMUNICATIONS section), and see if PHP's built-in mail function sends emails OK (no setup required, other than SMTP settings must be blanked out).
Important Note:
SMTP email sending is REQUIRED if you are running this app on a home network, or if reverse DNS hasn't been properly setup for the TLD domain hosted on this device (servers receiving email from this machine would likely blackhole it, or mark it as junk email).
If it is a bad or misconfigured proxy setup causing the issue, and everything runs great after disabling proxies, you probably have either (a) a bad proxy or proxy configuration, or (b) an API server / endpoint address is not responding properly when routed through proxies (example: HTTP used instead of HTTPS can cause this error). If you are absolutely sure your proxy setup is ok, and that an API connection built-in to this app is the issue, please report it.
If you already have plenty of disk space quota freed up / your cache folder permissions are readable / writable, and you still have file write issues on linux-based operating systems, you MAY need to setup a higher "open files" limit for your website user account. If you have shell access you can login and run this command to check your current limits:
If it's a low number like 1024, this MAY be the cause of your file write error issue (especially if you run multiple web apps that write a lot of data on the same account). If you are running a dedicated or VPS server, you can easily change this limit.
Running a google search for "set permanently ulimit -n linux", you'll find tons of articles on permanently upping your user's open files limit:
https://www.google.com/search?q=set+permanently+ulimit+-n+linux
To adjust the API timeout, go to the Admin Config POWER USER section. Adjust the 'remote_api_timeout' setting much higher, save the setup in the app, and run the app again to see if this fixes the issue. Adjust higher again if the issue still occurs frequently. DON'T SET 'remote_api_timeout' TOO HIGH though, or any unresponsive connections may cause the app to take a very long time to load / reload.
