如何以 root 身份运行 sudo 命令？
我只有服务器的根访问权限，因此 sudo 命令不起作用。我正在尝试运行一个尝试使用 sudo 命令的命令，但由于我已经具有 root 访问权限，所以它失败了。
未找到命令：sudo chmod +x /usr/local/bin/wkhtmltopdf
有没有办法让我运行此命令？我可以以某种方式退出 root 权限，或者让 root 暂时能够使用 sudo 命令吗？
I only have root access to my server and the sudo command therefore does not work. I am trying to run a command that tries to use the sudo command and as I already have root access, it fails.
command not found: sudo chmod +x /usr/local/bin/wkhtmltopdf
Is there a way that I can get this command to run? Can I move out of root somehow, or make root temporarily able to use the sudo command?

刚刚尝试过，它对我有用
（在 Mandriva Linux 上；其他发行版应该没有什么不同）。
您真的安装了
sudo吗？某些发行版上并非默认设置。
Just tried it and it worked for me
(on Mandriva Linux; other distros shouldn't be different).
Do you really have
sudoinstalled?It is not by default on some distros.
如果您以 root 身份登录，您不能在没有 sudo 的情况下运行命令吗？
IE
If you are logged in as root can't you just run your command without the sudo?
ie
正如其他人提到的，如果您已经是 root，通常不需要使用 sudo。但是，如果您编写一些脚本或类似的内容，并且需要在使用 root 用户而不是 root 用户时运行它，则需要将完整部分放入 sudo 命令中。
您可以找到从非 root 用户运行
whereis sudo的 sudo 应用程序所在位置。通常 sudo 位于：所以你可以在脚本中写入：
/usr/bin/sudo shutdown -h 现在
As others mentioned you normally don't need to use sudo if you are already root. But if you write some scripts or something like that and need to run it when you use root and not root users you need to put the full part to your sudo command.
You can locate where sudo app is situated running
whereis sudofrom a non-root user. Normally sudo situated at:So you can write in your script:
/usr/bin/sudo shutdown -h now
“我能以某种方式离开root吗？”
您可以创建另一个用户帐户，然后登录该帐户。
"Can I move out of root somehow?"
You could make another user account, and log into that.
看来您根本没有安装 sudo：
只需安装即可！ sudo 应默认配置为允许 root 无需询问即可调用
对于密码...
Seems you simply don't have sudo installed:
Just install it! sudo should be configured by default to allow being called by root without even asking
for password...
如果您已经是 root，则不需要 sudo。只需删除 sudo 这个词即可。
sudo 是一个以普通用户身份获取 root 访问权限的工具。
You don't need sudo if you already are root. Just remove the word sudo.
sudo is a tool to get root access as a normal user.
