![]() Combining standard industrial communication peripherals such as RS-485 capable UARTs and CAN-FD with a solid microcontroller foundation means that designers can implement a wide range of products in the industrial space. The simplicity/flexibility balance is important in many industrial applications. One aspect of the baseline family of parts is having options that deliver a good balance of simplicity and flexibility. The LPC5500 series has a wide range of offerings and with the recent release of the baseline LPC550x/S0x family of parts, there are plenty of device options all sharing the Cortex® M33 technology on a 40nm platform. Last year I wrote quite a bit about the new LPC5500 series MCUs focusing on the LPC55S69 and its ample processing capabilities.

Open the terminal and run the following command: Understanding reboot or ‘systemctl reboot’ or ‘shutdown -r now’ commands Personally, if I were you, I would shutdown the database server before issuing the reboot command.# systemctl poweroff # <- complete power off An alternative and recommended way is to type as shutdown/reboot is soft link to /sbin/systemctl:.Synchronize cached writes to persistent storage as root user by flushing everything to avoid problem with PostgreSQL/MySQL/MariaDB, run:.Best way to gracefully restart CentOS or RHEL Instead of typing “ sudo shutdown -r now“, we can type “ sudo reboot“. The last three command acts as a shortcut to a longer command and saves some typing. Please note that there is no need to press the power off button. Shut down and poweroff the system complety. poweroff command : Symlink or soft link to /sbin/systemctl to power off your CentOS/RHEL box.You still need to press the power-off button manually. halt command : Again, symbolic link and alias set to /sbin/systemctl to halt the CentOS/RHEL.reboot command : Symbolic link and aliased to /sbin/systemctl to restart the CentOS/RHEL.systemctl command : Systemd’s systemctl command can reboot or shutdown your server too.shutdown command : All in one command to halt, power-off or reboot the machine.RHEL/CentOS Linux commands that we can use to restart the server carefully: Restarting CentOS or RHEL server safely over ssh
