echo shell_exec("sudo bash.sh 2>&1");

sudo: no tty present and no askpass program specified
www-data is not in the sudoers file.  This incident will be reported.

There are a couple of issues you might encounter: 您可能会遇到几个问题：

The user that is running the php process must have sudo rights (check with visudoers command) 运行php进程的用户必须具有sudo权限（请使用visudoers命令检查）
There is no environment set, so the $PATH variable does not include the path to the sudo command 没有设置环境，因此$PATH变量不包含sudo命令的路径
sudo might require a password. sudo可能需要密码。 Either change the sudoers file, adding NOPASSWORD , which would be hugely unsafe. 更改sudoers文件，添加NOPASSWORD ，这将是非常不安全的。 Or you have to use pipes ( proc_open ), and pass the password through the stdin pipe 或者，您必须使用管道（ proc_open ），并通过stdin管道传递密码

I've managed to find a way to do so, but after some help from people on this site: 我设法找到了一种方法，但是在此站点上的人提供了一些帮助之后：
