echo "deb https://deb.debian.org/debian buster-backports main" | tee /etc/apt/sources.list.d/buster-backports.list
apt update
apt -t buster-backports install shadowsocks-libev
ss-server -v
systemctl status shadowsocks-libev
systemctl enable shadowsocks-libev

现在我们需要编辑默认配置文件。

nano /etc/shadowsocks-libev/config.json
