How to view and manage processes on CentOS?

To view and manage processes on CentOS, you can use several commands in the terminal.

Viewing Processes:

• ps: This command displays information about a selection of the active processes. For example, ps aux will list all running processes with detailed information.
• top: This command provides a dynamic real-time view of the running system. It displays a list of processes that are currently running on the system, sorted by CPU usage by default.

Managing Processes:

• kill: This command sends a signal to a process, usually to terminate it. For example, kill [PID] will send the default signal (TERM) to the process with the specified Process ID (PID). If the process does not terminate, you can use kill -9 [PID] to send a SIGKILL signal, which forcefully terminates the process.
• killall: This command terminates all processes with a given name. For example, killall httpd will stop all httpd processes.
• pkill: Similar to killall, pkill allows you to terminate processes based on criteria such as process name, user, group, etc. For example, pkill -u username will terminate all processes owned by the specified user.

For more advanced process management and monitoring, you might consider using tools like systemd or supervisord, which offer more comprehensive control over services and applications running on your CentOS system.

If you're looking for a cloud-based solution to manage your CentOS servers and processes more efficiently, consider using services like Tencent Cloud's Cloud Monitor or Tencent Cloud's Container Service (TKE), which provide monitoring and management capabilities for your cloud-based applications and infrastructure.
