一条命令将Linux应用安装为systemd服务运行

脚本install-app-as-service.sh：

#!/bin/bash

# 检查参数是否正确
if [ $# -ne 1 ]; then
    echo "Usage: $0 <target-directory or executable-file>"
    exit 1
fi

TARGET="$1"

# 根据输入参数的类型选择操作模式
if [ -f "$TARGET" ] && [ -x "$TARGET" ]; then
    # 单个可执行文件模式
    echo "Single executable file detected. Installing as a service."
    
    # 获取基本信息
    executable="$TARGET"
    service_name=$(basename "$executable").service
    service_path="/etc/systemd/system/$service_name"
    exec_path=$(realpath "$executable")
    work_dir=$(dirname "$exec_path")

    echo "Installing $exec_path as systemd service: $service_name"

    # 生成服务文件内容（包含路径转义）
    service_content="[Unit]
Description=Service for $(basename "$executable")
After=network.target

    # 写入系统服务文件
    echo "$service_content" | sudo tee "$service_path" > /dev/null

    # 设置文件权限
    sudo chmod 644 "$service_path"

    # 重新加载systemd并启用服务
    sudo systemctl daemon-reload
    sudo systemctl enable "$service_name"
    sudo systemctl start "$service_name"

    echo "Successfully installed and started $service_name"

elif [ -d "$TARGET" ]; then
    # 目录模式，与原来功能一致
    echo "Directory mode: Installing all executables in directory as services."
    
    # 查找所有可执行文件并处理
    find "$TARGET" -maxdepth 1 -type f -executable | while read -r executable; do

    echo "All executable services installed from $TARGET"
else

使用：

sudo install-app-as-service.sh path-to-the-app(指向单个可执行程序）
sudo install-app-as-service.sh path-to-the-dir(指向可执行程序上级目录，支持多个批量安装）
