检查 Linux 服务状态并在停止使用 Python 脚本时启动它

Question

I have a fixed list of services in a Linux server. I want to check the status of these services and start the service if it's stopped. I'm able to get this done using a shell script, but I'm looking for a Python script to do this.

Answer 1

You can use python subprocess.Popen or os.system .

Example:

subprocess.Popen(["sudo", "service", "redis", "start"])

subprocess.Popen(["sudo", "service", "redis", "status"], stdout=subprocess.PIPE)

You can read the stdout and check if the process is stopped and also see the exist status.

Alternatively you can use psutil to monitor processes.
