Can I run a Python script as a service?
提问by TheFlash
Is it possible to run a Python script as a background service on a webserver? I want to do this for socket communication.

You can make it a daemon. There is a PEP for a more complete solution, but I have found that this works well.
你可以让它成为一个守护进程。有一个更完整的解决方案的 PEP，但我发现这很有效。
import os, sys
def become_daemon(our_home_dir='.', out_log='/dev/null', err_log='/dev/null', pidfile='/var/tmp/daemon.pid'):
""" Make the current process a daemon. """
try:
# First fork
try:
if os.fork() > 0:
sys.exit(0)
except OSError, e:
sys.stderr.write('fork #1 failed" (%d) %s\n' % (e.errno, e.strerror))
sys.exit(1)
os.setsid()
os.chdir(our_home_dir)
os.umask(0)
# Second fork
try:
pid = os.fork()
if pid > 0:
# You must write the pid file here. After the exit()
# the pid variable is gone.
fpid = open(pidfile, 'wb')
fpid.write(str(pid))
fpid.close()
sys.exit(0)
except OSError, e:
sys.stderr.write('fork #2 failed" (%d) %s\n' % (e.errno, e.strerror))
sys.exit(1)
si = open('/dev/null', 'r')
so = open(out_log, 'a+', 0)
se = open(err_log, 'a+', 0)
os.dup2(si.fileno(), sys.stdin.fileno())
os.dup2(so.fileno(), sys.stdout.fileno())
os.dup2(se.fileno(), sys.stderr.fileno())
except Exception, e:
sys.stderr.write(str(e))

There is the very helpful Pypi packagewhich is the basis for my daemons written in Python.
有一个非常有用的Pypi 包，它是我用 Python 编写的守护进程的基础。

on XP and later you can use the sc.exeprogram to use any .exe as service:
在 XP 及更高版本上，您可以使用sc.exe程序将任何 .exe 用作服务：
>sc create
Creates a service entry in the registry and Service Database.
SYNTAX:
sc create [service name] [binPath= ] <option1> <option2>...
CREATE OPTIONS:
NOTE: The option name includes the equal sign.
type= <own|share|interact|kernel|filesys|rec>
(default = own)
start= <boot|system|auto|demand|disabled>
(default = demand)
error= <normal|severe|critical|ignore>
(default = normal)
binPath= <BinaryPathName>
group= <LoadOrderGroup>
tag= <yes|no>
depend= <Dependencies(separated by / (forward slash))>
obj= <AccountName|ObjectName>
(default = LocalSystem)
DisplayName= <display name>
password= <password>
You can start your pythonscript by starting the python interpreter with your script as argument:
您可以通过使用您的脚本作为参数启动 python 解释器来启动您的 pythonscript：
python.exe myscript.py

如果您在谈论 linux，那么就像执行 ./myscript.py & 之类的事情一样简单
