Linux Ubuntu安装Syncthing

添加官方仓库源并安装

sudo mkdir -p /etc/apt/keyrings
sudo curl -L -o /etc/apt/keyrings/syncthing-archive-keyring.gpg https://syncthing.net/release-key.gpg

echo "deb [signed-by=/etc/apt/keyrings/syncthing-archive-keyring.gpg] https://apt.syncthing.net/ syncthing stable" | sudo tee /etc/apt/sources.list.d/syncthing.list

echo "deb [signed-by=/etc/apt/keyrings/syncthing-archive-keyring.gpg] https://apt.syncthing.net/ syncthing candidate" | sudo tee /etc/apt/sources.list.d/syncthing.list

sudo apt-get update
sudo apt-get install syncthing

创建systemd服务

创建服务文件：

sudo vim /etc/systemd/system/syncthing@.service

粘贴以下内容：

[Unit]
Description=Syncthing - Open Source Continuous File Synchronization for %i
Documentation=man:syncthing(1)
After=network.target

[Service]
User=%i
ExecStart=/usr/bin/syncthing serve --no-browser --no-restart --logflags=0
Restart=on-failure
RestartSec=5
SuccessExitStatus=3 4
RestartForceExitStatus=3 4

[Install]
WantedBy=multi-user.target

应用并启动服务

sudo systemctl daemon-reload
sudo systemctl enable syncthing@$(whoami)
sudo systemctl start syncthing@$(whoami)

# 验证服务状态
systemctl status syncthing@$(whoami)

更改为局域网访问（可选）

如果是无桌面环境的服务器安装，可能需要执行这一步

打开配置文件
```
vim ~/.local/state/syncthing/config.xml
```

找到<gui>部分并将127.0.0.1修改为0.0.0.0

    <gui enabled="true" tls="false" debugging="false" sendBasicAuthPrompt="false">
        <address>0.0.0.0:8384</address>
        <metricsWithoutAuth>false</metricsWithoutAuth>
        <apikey>xxxxxxxxx</apikey>
        <theme>default</theme>
    </gui>
