Thanks, I've got a lot to learn....Rob

RDK

I followed the steps in the Jan 2019 entry at this reference ( https://lb.raspberrypi.org/forums/viewtopic.php?t=25978#p1397915 ) and it seems to be working: $ sudo /etc/init.d/mysql stop $ sudo mkdir /path/to/new/datadir $ sudo cp -R /var/lib/mysql/* /path/to/new/datadir $ sudo nano /etc/mysql/my.c...

RDK

Thanks. The partition (usb stick) is mounted since I can access (via Simba) other files on it, both before and after I tried to restart the service. What should the permissions be set to?....RDK

RDK

I added "nofail" to my mount statement in the fstab and also converted it to use the UUID. That has been working now for several weeks. and I have started using MariaDB and setting up users, etc, but no databases. Today I tried to make the changes suggested by rpdom on April 7 so I could have my dat...

Heater....I have installed VS_Code on my laptop and I think it is operational. Seems like I have a lot to learn but it looks like something close to my wants. EDIT: My error: When coding an object, for example c=open(….), and I type x=c. I expected then to immediately get a drop-down of the methods ...

RDK

B.Goode...No, I have not installed those libraries on the laptop. I've looked for a Windows install for pyModbus without success.

Heater....Sounds interesting. I will look at it...RDK

RDK

OK, well, I in fact installed it from the GIT sudo git clone https://github.com/sourceperl/pyModbusTCP.git Now should I reinstall as you propose? How do I remove the clone installed library? Thinking about it I have many libraries which I installed via the clone process, for example RTL_433. Is ther...

RDK

I have a problem with Python 3 not finding a module library, but Python 2.7 does. Here is a VERY simple program: #!/usr/bin/env python # -*- coding: utf-8 -*- from pyModbusTCP.client import ModbusClient print("hello world") Below you can see back to back runs of this program only switching from pyth...

RDK

Andyroo: Thanks for the idea. Currently in my /etc/fstab I have this line: /dev/sda1 /mnt/usbdrive vfat defaults,dmask=000,fmask=111 0 0 which is configured to work for SAMBA read/write file sharing. If I understand you, and in practice it works like this, if I change USB sticks it does not matter a...

RDK

Currently I'm writing code on my Windows 10 Pro laptop using IDLE and then transferring the code to a Raspberry Pi to run. For the Pi I've installed some object packages, like RTL_433, pyModbus, etc, from a GIT site or other sources. My code generally works on the Pi, but on the laptop when coding I...

RDK

Great, I actually understand what you have proposed. Now how do I insure that it is mounted before MariaDB starts? The USB stick is defined in the /etc/fstab. Is that sufficient?...RDK

RDK

Douglas.....All of the files in the concatenation list in this file (/etc/mysql/my.cnf) , shown below, were either empty or did not contain the directory information # The MariaDB/MySQL tools read configuration files in the following order: # 1. "/etc/mysql/mariadb.cnf" (this file) to set global def...

RDK

I realize that this is an old posting, but I have just installed MariaDB on my Pi 3b running Stretch. Before I start any database development I would like to have the data stored/accessed on an external HD or USB stick. With the passage of time and the MariaDB MySQL replacement on Raspbian Stretch, ...

RDK

OK, correct me if I'm wrong: 1. to create the non- root user with root powers (ie "admin") I have to use the sudo mysql command? and then create user 'admin'@'localhost' identified by 'a good pw'; grant all privileges on *.* to 'admin'@'localhost' with grant option; 2. After that I use the mysql -u ...

RDK

Thanks. I'll re-read this the study your links. RDK

RDK

Not sure why, but after two reboots it is now working correctly....RDK

RDK

OK, but when I ran the

Code: Select all

sudo mysql -u root -p

command I tried to use a different user id and PW but that was rejected. When I ran it again with root as the user and used the REAL root password for my box, it worked. I'm not real happy to have it require the REAL root id and password....RDK

RDK

Thanks....good to know I'm not the only one out walking in the wilderness

I'll check these out....RDK

RDK

I set out to install MySQL but I gather that Raspbian is now working with MariaDB and that it is fully compatible with MySQL. Ok no problem as I'm a new user to either. I installed like this: $ sudo apt-get install mariadb-server $ sudo mysql -u me -p Enter password: ERROR 1698 (28000): Access denie...

I'm an old time programmer brought up writing Fortran programs, ie what folks now call Procedural Programming. I've written a few things in Python, but for sure have not used many of the object-oriented features which are available. I'm reading a couple books right now on the subject, but they mostl...

Note: Pi B+ Continuing the saga from my previous posts: I found a Bluetooth dongle and reran these commands: sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade The last one took forever (5+ hours), but finished with no errors. However, now when I boot-up, I get this message: failed t...

Yes, I just finished upgrading to Stretch via this reference (https://www.datenreise.de/en/raspberry-pi-raspbian-update-update-jessie-to-stretch/). And, yes, I got basically the same errors from the sudo apt-get dist-upgrade and the sudo apt-get autoremove commands Is there a way to tell it not to l...

RDK

Yesterday I decided to update this Pi B+ currently running Jessie. I ran the sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade The first two completed normally, but the last sudo apt-get dist-upgrade ended with an error Setting up bluez (5.23-2+rpi2) ... Job for bluetooth.service fa...

RDK

OK, I edited /etc/profile and when I echo $PATH it shows the change. However, I not sure this will affect other users on the Pi....RDK

RDK

OK, I saw that reference, but mostly it confused me!! There are/were too many answers and they often seemed to be in conflict. Mostly I want one simple answer. But, I will go back for another look....ROK
