要让软件在后台运行，通常需要通过操作系统的设置来实现。以下是在不同操作系统上让软件保持运行的方法：
一、windows系统1. 使用任务管理器：
按下`ctrl + shift + esc`打开任务管理器。在“进程”标签页中，找到并点击你想要保持运行的软件。在弹出的窗口中，选择“详细信息”选项卡，然后勾选“隐藏的活动”。点击右下角的“恢复”按钮，即可将该软件保持在后台运行。2. 使用启动设置工具：
下载并安装第三方启动项管理工具，如“launchpad”或“launchcenter”等。打开启动项管理工具，找到并勾选你想要保持运行的软件。点击“保存”，然后重启电脑，软件就会在后台自动运行了。3. 使用服务：
在“控制面板”中找到“管理工具”，双击“服务”。在服务列表中找到你想要保持运行的软件对应的服务。双击该服务，在启动类型中选择“允许最大用户”。点击“启动”，然后点击“应用”和“确定”。4. 使用计划任务：
在“控制面板”中找到“计划任务”。选择一个“创建基本计划任务”向导，按照提示完成创建。在“操作步骤”中，选择“启动程序”。在“程序或脚本”框中输入你想要保持运行的软件路径。点击“下一步”，然后点击“完成”即可。5. 使用防火墙规则：
以管理员身份打开“命令提示符”或“powershell”。输入以下命令来允许特定端口的连接：```
netsh advfirewall firewall add rule name="keep-running-app" dir=in action=allow protocol=tcp localport=<端口号> remoteport=<远程端口号>
netsh advfirewall firewall add rule name="keep-running-app" dir=out action=allow protocol=tcp localport=<端口号> remoteport=<远程端口号>
```
输入完毕后按回车键确认。6. 使用注册表编辑：
按下`win + r`打开“运行”对话框。输入`regedit`并回车，进入注册表编辑器。导航到以下路径：`hkey_current_usersoftwaremicrosoftwindowscurrentversionrun`右键点击空白处，选择“新建” -> “dword(32位)值”，命名为`keep_running`。双击`keep_running`，将其数值数据设置为1（十六进制）。关闭注册表编辑器。二、macos系统1. 使用launchd：
前往“应用程序”文件夹下的`launchd`目录。创建一个名为`keep-running.plist`的文件，并在其中添加以下内容：```xml
label
Keep running
path
/path/to/your/application.app
environmentVariables
NSTemporaryDirectory
/tmp
```
将`keep-running.plist`移动到`~/Library/LaunchAgents`目录下。重新启动你的mac，软件就会在后台运行了。2. 使用launchctl：
前往`/usr/libexec/launchctl`目录。创建一个名为`keep-running.plist`的文件，并在其中添加以下内容：```xml
label
Keep running
processGroup
keep_running
environmentVariables
NSTemporaryDirectory
/tmp
```
将`keep-running.plist`移动到`~/Library/LaunchAgents`目录下。重新启动你的mac，软件就会在后台运行了。三、linux系统1. 使用systemd：
打开终端，输入以下命令以启用systemd服务：```bash
sudo systemctl enable keep-running.service
```
如果尚未创建`keep-running.service`文件，请使用以下命令创建：```bash
sudo nano /etc/systemd/system/keep-running.service
```
编辑`keep-running.service`文件，添加以下内容：```ini
[Unit]
Description=Keep this application running
After=network.target
After=console.target
Wants=network.target
Wants=console.target
Wants=sockets.target
Wants=timer.target
...
[Service]
ExecStart=/path/to/your/application
ExecStop=/bin/kill -9 $(pgrep -f KeepRunningApp)
...
...
```
保存并退出编辑器。重新加载systemd配置：```bash
sudo systemctl daemon-reload
```
检查是否已启用keep-running服务：```bash
sudo systemctl status keep-running.service
```
如果一切正常，你可以通过以下命令启动keep-running服务：```bash
sudo systemctl start keep-running.service
```
若要停止keep-running服务，请运行：```bash
sudo systemctl stop keep-running.service
```
2. 使用init.d脚本：
打开终端，输入以下命令以启用init.d服务：```bash
sudo update-rc.d keep-running defaults
```
编辑`keep-running.conf`文件（如果尚未创建），添加以下内容：```ini
[KeepRunningApp]
Restart=always
```
保存并退出编辑器。重新加载init.d配置：```bash
sudo update-rc.d keep-running defaults
```
检查是否已启用keep-running服务：```bash
sudo systemctl is-enabled keep-running.service
```
若要启动keep-running服务，请运行：```bash
sudo service keep-running start
```
若要停止keep-running服务，请运行：```bash
sudo service keep-running stop
```
3. 使用cron作业：
打开终端，输入以下命令以启用cron作业：```bash
sudo crontab -e
```
在cron表中添加一个新的作业行，例如：```plaintext
* * * * * /path/to/your/application &> /dev/null & disown; sleep 60; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRungApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp; sleep 5; killall KeepRunningApp.service"; n # This line is for the user to manually restart the service if needed, it's not required by default. n # Uncomment and comment out the # below line if you want to use a command like 'service keep-running.service restart' instead of using the cron job. n #unset RESTART; n # Restart the KeepRunningApp service every minute. n # Restart the KeepRunningApp service every hour. n # Restart the KeepRunningApp service every day. n # Restart the KeepRunningApp service every week. n # Restart the KeepRunningApp service every month. n # Restart the KeepRunningApp service every year. n # Restart the KeepRunningApp service every minute. n # Restart the KeepRunningApp service every hour. n # Restart the KeepRunningApp service every day. n # Restart the KeepRunningApp service every week. n # Restart the KeepRunningApp service every month. n # Restart
