Deploying MarketData a) Stop the cron sevice. sudo service cron stop b) Check that MarketData is not running any tasks... ps xa | grep MarketData. mks might be running but that should be all b) Open Folder ARM64 and do dotnet clean followed by dotnet build c) Locate the build files in /home/pi/ARM64/MarketData/MarketData/bin/Debug/net8.0 d) Backup the /opt/MarketData/MarketData files into /opt/MarketData/MarketData_Rollback e) Delete all but the logs folder from the /opt/MarketData/MarketData folder f) Copy files from /home/pi/ARM64/MarketData/MarketData/bin/Debug/net8.0 into /opt/MarketData/MarketData g) Restart cron service.. sudo service cron restart h) Ensure that cron is running sudo service cron status
Deploying MarketDataService a) Disable the service sudo systemctl disable mks b) Stop the service. sudo systemctl stop mks This might take 30 seconds c) Copy all files from /opt/MarketData/MarketDataServer to /opt/MarketData/MarketDataServer_Rollback d) Delete all but the logs folder from /opt/MarketData/MarketDataServer e) Copy files from /home/pi/ARM64/MarketDataServer/bin/Debug/net8.0 into /opt/MarketData/MarketDataServer f) Enable the service sudo systemctl enable mks g) Start the service sudo systemctl restart mks h) Ensure that the service running systemctl status mks
Deploying IPMonitor a) Stop the cron service. sudo service cron stop b) Check that IPMonitor is not running. ps xa | grep ipmonitor notes: crontab -e shows the process in lower case c) Delete all but the ipaddress and logs folders from /opt/MarketData/IPMonitor d) Copy files from /home/pi/ARM64/IPMonitor/bin/Debug/net8.0 into /opt/MarketData/IPMonitor e) Restart the cron service. sudo service cron restart f) Ensure that cron cron is running sudo service cron status

Adding notes on MariaDb as I plan to migrate the MySql over to one of the Raspberry PI 4 B's https://hevodata.com/learn/mysql-to-mariadb/

journalctl --disk-usage # See log file disk use sudo journalctl --vacuum-size=200M # Drop log file size to 200M, if possible. sudo journalctl --vacuum-time=10d # Drop logs, over 10 days old

DEV NULL
ping a.b.c > /dev/null 2>&1

CRON SCHEDULE sudo crontab -e

** THE LATEST AND GREATEST IS ALWAYS AT THE BOTTOM

Also note that 1>/dev/null is synonymous to, but more explicit than >/dev/null

Here is the official latest crontab. Adding the monthly jobs to run on the 17th Notice that the monthly jobs will all run on the 15th of the month at 00:00 (zero hour and zero minute=midnight) CalcSticker will also start on the 15th but 15 seconds past midnight. It will wait for the completion of the specified processes

crontab is... (minute) (hour) (day of month) (month) (day of week)

The following is the production crontab. you can directly copy these lines into the cron schedule...

Stop the cron service. sudo service cron stop
Copy/Paste daya ... sudo crontab -e and then copy the below lines
Restart cron sudo service cron restart
Ensure cron is running sudo service cron status
