用 asyncio 重写 shadowsocks
- 安装
pip install aioshadowsocks
- 多用户配置
aioshadowsocks 将json作为配置文件, 会读取当前目录下 userconfigs.json
作为默认的配置文件
{
"users": [
{
"user_id": 1,
"port": 2345,
"method": "none",
"password": "hellotheworld1",
"transfer": 104857600,
"speed_limit": 0
},
{
"user_id": 2,
"port": 2346,
"method": "chacha20-ietf-poly1305",
"password": "hellotheworld2",
"transfer": 104857600,
"speed_limit": 384000
}
]
}
同时也支持从http服务器读取配置文件,这时需要注入环境变量 SS_API_ENDPOINT
作为读取配置的api地址
- 注入环境变量
export SS_API_ENDPOINT="https://xxx/com"
- 启动ss服务器
aioss run_ss_server
- install docker
curl -sSL https://get.docker.com/ | sh
- install docker-compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
- apply executable permissions
sudo chmod +x /usr/local/bin/docker-compose
- run server
docker-compose up
主要想通过这个项目的推进来深入了解 asyncio
另外我的一个项目: django-sspanel 依赖 shadowsocksr
但该项目已经停止开发了,所以决定重新造个轮子
- tcp/udp 代理
- 流量统计
- 速率控制
- 开放了grpc接口(类似ss-manager)
- 单端口多用户(利用AEAD加密在不破坏协议的情况下实现)
- prometheus/grafana metrics监控 (dashboard在项目的static/grafana/文件夹下)
Shadowsocks本身是一个IO密集行的应用,但是由于加入了AEAD加密,使得SS本身变成了CPU密集行的应用 而Python本身是不太适合CPU密集的场景的,所以在AEAD模式中的表现不佳 PS: 当然,其实是我代码写的烂,python不背锅
- Steam-Cipher-None(不加密 高IO)
- AEAD-Cipher-CHACHA-20(加密 高CPU)
