Run a python script forever

In this section, we are going to show how to run a python script as a systemd service, allowing you to boot it at the start of a Linux machine and to maintain it alive.

Test method: Telegram Bot

We are going to use a very basic Telegram bot in order to test that our script will:

1. Automatically start when the machine boot
2. Automatically restart when it crashes/exits for whichever reason

If you are getting this in gdb on macOS while trying to run a program:

Unable to find Mach task port for process-id 57573: (os/kern) failure (0x5).
 (please check gdb is codesigned - see taskgated(8))

1. Open Keychain Access
2. In menu, open Keychain Access > Certificate Assistant > Create a certificate
3. Give it a name (e.g. gdbc)

good, 你已经有了一个自己的shadowsocks代理了，现在想要把这个代理公布出去给所有人分享。
但是没有两个小时，代理就没法使用了，为什么？因为你需要额外注意以下事项（以下步骤需要比较高的linux技能）
本文只关注于确保shadowsocks服务还“活着”，如果你希望让其跑得更快，请参考 
https://github.com/clowwindy/shadowsocks/wiki/Optimizing-Shadowsocks

1、 shadowsocks的timeout设置
超时时间越长，连接被保持得也就越长，导致并发的tcp的连接数也就越多。对于公共代理，这个值应该调整得小一些。推荐60秒。

2、 检查操作系统的各种限制
对于openvz的vps，特别需要检查一下
