HomeBackend DevelopmentPython Tutorialpython进程管理工具supervisor使用实例

平时我们写个脚本,要放到后台执行去,我们怎么做呢?

代码如下:


nohup python example.py 2>&1 /dev/null &

用tumx或者screen? 但是用着可能都不爽,今天就看看python里面的一个进程管理工具supervisor:

官方说:Supervisor: A Process Control System

说白了他就是一个demon程序,他来帮助我们完成对我们想要托管的脚本也好程序也好,好好的照料;

1、安装

python的东西就是好安装,如果是centos系列,可以使用:

代码如下:


yum install supervisor


如果是debin系列的:

代码如下:


apt-get install supervisor

或者干脆点:

代码如下:


easy_install supervisor
pip install supervisor

2、创建配置文件

你可以使用自带的一个工具:echo_supervisord_conf
默认是在/etc下 创建,但需要你有root权限:

代码如下:


echo_supervisord_conf > /etc/supervisord.conf


当然也可以是其它目录,但需要在启动的时候指定(-c)

3、启动Supervisor

接下来我们来看看怎么启动supervisord 和 supervisorctl

首先找一个要托管的程序,比如/bin/date

代码如下:


vim /etc/supervisord.conf

[program:test]
command=python /root/test_supervisor.py
process_name=%(program_name)s
stdout_logfile=/root/test.log
stderr_logfile=/root/test.log


保存,启动:

代码如下:


/usr/bin/supervisord -c /etc/supervisord.conf

发送信号:

肿么样,很爽吧,接下来,就可以自由发挥了。。。
http://supervisord.org/ 这是官网。
最后的最后,他还可以界面管理哦,这也为我们在界面进行进程管理提供了一种方法哦!

How to concatenate two lists in python 3?How to concatenate two lists in python 3?May 14, 2025 am 12:09 AM

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.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
