Aria2 是一个轻量级的多协议下载工具，支持 HTTP/HTTPS、FTP、BitTorrent 和 Metalink。

apt update\napt install aria2\n

配置 Aria2

创建配置文件 /root/aria2/aria2.conf：

# 下载目录\ndir=/media/sda-ext/download\n\n# 断点续传\ncontinue=true\ndisable-ipv6=true\n\n# RPC 服务\nenable-rpc=true\nrpc-listen-all=true\nrpc-listen-port=9800\nrpc-secret=admin\nrpc-allow-origin-all=true\n\n# 下载优化\nmax-concurrent-downloads=5\nmax-connection-per-server=16\n

配置说明：

dir: 下载文件保存目录
rpc-secret: RPC 接口密码，用于 Web UI 认证
max-connection-per-server: 单服务器最大连接数，提升下载速度

创建 systemd 服务

创建服务文件 /etc/systemd/system/aria2.service：

[Unit]\nDescription=Aria2, Download Manager\nAfter=network.target\n\n[Service]\nType=simple\nRestart=always\nExecStart=/usr/bin/aria2c --conf-path=/root/aria2/aria2.conf\n\n[Install]\nWantedBy=multi-user.target\n

启动服务

# 启动服务\nsystemctl start aria2\n\n# 设置开机自启\nsystemctl enable aria2\n\n# 查看服务状态\nsystemctl status aria2\n

Web UI 管理

Aria2 支持通过 Web UI 进行管理，推荐使用 AriaNg 或 webui-aria2。
