以root用户创建目录/etc/shadowsocks-rust，编辑/etc/shadowsocks-rust/config.json：

{
    "servers": [
        {
            "address": "127.0.0.1",
            "port": 1080,
            "password": "hello-world",
            "method": "aes-256-cfb"
            "timeout": 300
        },
        {
            "address": "127.0.0.1",
            "port": 1081,
            "password": "hello-kitty",
            "method": "aes-256-cfb"
        }
    ],
    "local_port": 8388,
    "local_address": "127.0.0.1"
}

配置文件请根据自己的需求修改.

配置shadowsocks-rust服务

以root用户创建/etc/systemd/system/shadowsocks-rust.service:

[Unit]
Description=Shadowsocks-Rust Custom Client Service.
Documentation=sslocal -h
After=network.target

[Service]
Type=simple
CapabilityBoundingSet=CAP_NET_BIND_SERVICE
AmbientCapabilities=CAP_NET_BIND_SERVICE
User=nobody
Group=nogroup
ExecStart=/usr/local/bin/sslocal --log-without-time -c /etc/shadowsocks-rust/config.json

[Install]
WantedBy=multi-user.target

注册并启动服务：

chown -R root:nogroup /etc/shadowsocks-rust
chmod -R g-w,o-rwx /etc/shadowsocks-rust
systemctl daemon-reload
systemctl enable shadowsocks-rust
systemctl start shadowsocks-rust

注意:

为降低sslocal进程权限，以nobody用户和nogroup组运行它。
为防止密码泄漏，/etc/shadowsocks-rust/config.json仅root用户或nogroup组可读。
限制sslocal进程仅能监听socket.
