crtrl.py监控Apache服务器进程的Python 脚本

复制代码 代码如下:

!/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) print "apache 进程异常退出, 4 秒后重新启动"
time.sleep(3)
os.system("service apache2 restart")
except:
print "Error", sys.exc_info()[1]

设置文件权限为执行属性(使用命令 chmod +x crtrl.py),然后加入到/etc/rc.local 即可,一旦 Apache 服务器进程异常退出,该脚本自动检查并且重启。 简单说明一下清单 5 这个脚本不是基于/proc 伪文件系统的,是基于 Python 自己提供的一些模块来实现的 。这里使用的是 Python 的内嵌 time 模板,time 模块提供各种操作时间的函数。

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Python concatenate list stringsPython concatenate list stringsMay 14, 2025 am 12:08 AM

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Python: compiler or Interpreter?Python: compiler or Interpreter?May 13, 2025 am 12:10 AM

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
