在 AWS EC2 中将 Python 配置为服务 [英] Configure a Python as a service in AWS EC2

问题描述

如何将 Python 脚本配置为在 Amazon AWS EC2 实例中作为服务运行(系统重启时重新启动，失败时重新启动)?

How do I configure a Python script to run as a service (re-launch on system restart, restart on failure) in Amazon AWS EC2 instance?

推荐答案

您可以在 ec2 实例上创建一个 systemd 服务来实现这一点.步骤是:

You can create a systemd service on the ec2 instance to achieve this. Steps are:

1. 创建服务定义文件:

1. Create a service definition file:

sudo vi /lib/systemd/system/mypythonservice.service

添加 systemd 单元文件定义.您可以查看this 或 systemd 参考指南更多详情:

Add the systemd unit file definition. You can check this or the systemd reference guide for more details:

[Unit]
Description=My Python Service
After=multi-user.target

[Service]
Type=idle
ExecStart=/usr/bin/python /home/myuser/mypythonproject.py
Restart=on-failure

[Install]
WantedBy=multi-user.target

为文件设置必要的权限:

Set the necessary permissions on the file:

sudo chmod 644 /lib/systemd/system/mypythonservice.service

重新加载 systemd 守护进程:

Reload the systemd daemon:

sudo systemctl daemon-reload

启用服务在重启时启动:

Enable the service to start on reboot:

sudo systemctl enable mypythonservice.service

当然，您可以将所有这些添加为 EC2 实例用户数据脚本的一部分，以便在实例启动时自动配置.

And of course you can add all of this as part of a EC2 Instance User Data script to automatically configure on instance launch.
