1. 安装Aria2

该文所使用的系统是Ubuntu 20.04.3 LTS，并且以守护进程的方式运行Aria2。最终效果如下：

aria2-config

1. 安装Aria2

$ sudo apt install aria2

2. 配置Aria2

在**/home/www/aria2/**下创建aria2.conf文件。以下是我的配置文件，配置里有注释，可作为参考。

3. 服务开机自启

使用systemctl添加服务，并设为开机自启

1. 在**/lib/systemd/system/**目录下，新建文件aria2.service，内容如下：

[Unit]
Description=Aria2c service
After=network.target

[Service]
User=www-data
Group=www-data

Type=forking
ExecStart=aria2c --conf-path=/home/www/aria2/aria2.conf -D
#KillMode=mixed

[Install]
WantedBy=multi-user.target

以守护进程的方式启动Aria2，并且给aria2服务最小的权限，我这里限定以www-data用户的身份运行。注意替换配置文件路径位置。

2. 使能开机自动启动

sudo systemctl enable aria2.service

3. 启动/停止服务

sudo systemctl start aria2.service
sudo systemctl stop aria2.service

4. 防火墙配置

开放Aria2端口：

# IPv4
iptables -A INPUT -p tcp -m multiport --dports 9800,51413 -j ACCEPT # aria2 rpc and aria2 bt
iptables -A INPUT -p udp --dport 6881:6999 -j ACCEPT # aria2 dht

# IPv6 同 ipv4, 略
