[Ubuntu] 系统非 root 账号,安装了 xxxapp 后,运行权限是属于 root? 还是所有 users?

发表于

有些云服务商默认 Server 的账号是 root ,有一些则是另外建一个 newuser1 账号。登录 newuser1 安装应用就要 sudo apt-get install xxxapp 之后,运行权限是属于 root? 还是所有 users?

  1. sudo apt-get install xxxapp 安装的路径,算是在 root 用户下面?还是在 newuser1 下面?
  2. sudo apt-get install xxxapp 安装的应用,运行权限是不是 root 权限?另外在创建一个 newuser2 有没有权限直接运行 xxxapp ?
  3. 如果 xxxapp 需要加入到系统开机自启动服务中,比如 systemd 中,是否需要添加 root 运行权限?
