Linux system uses Python to monitor Apache server process script sharing

crtrl.py python script to monitor Apache server processes

Copy the Code code as follows:

!/usr/bin/env Python
Import OS, sys, time

While True:
Time.sleep (4)
Try
ret = Os.popen (' ps-c apache-o pid,cmd '). ReadLines ()
If Len (ret) < 2:
Print "Apache process quits unexpectedly, restarts after 4 seconds"
Time.sleep (3)
Os.system ("Service apache2 restart")
Except
Print "Error", Sys.exc_info () [1]

Set file permissions to execute properties (using command chmod +x crtrl.py), and then join to/etc/rc.local, which automatically checks and restarts once the Apache server process exits abnormally. A brief description of listing 5 This script is not based on the/proc pseudo file system, but is based on some of the modules provided by Python itself. This is the embedded time template for Python, which provides functions for various operating times.
