The "no tty present" error indicates that you have the 'requiretty' setting in your sudoers file. In your case, it is probably in /etc/sudoers.d. Once this line is there, it does not matter what group you are in - sudo will require a tty whenever it is executed.
“不存在 tty”错误表明您的 sudoers 文件中有“requiretty”设置。在您的情况下，它可能在 /etc/sudoers.d 中。一旦有了这一行，无论您在哪个组中都无关紧要 - sudo 每次执行时都需要一个 tty。
To get around this, you need to either remove (or comment out) the requiretty line in the configuration file, or add a line to exclude your user from the requiretty setting. You can see how to do that here: Disable requiretty per user
要解决此问题，您需要删除（或注释掉）配置文件中的 requiretty 行，或者添加一行以从 requiretty 设置中排除您的用户。您可以在此处查看如何执行此操作： Disable requiretty per user

By adding the following: Defaults:username !authenticate to your /etc/sudoers you should not get the error but this username will be accessible without asking for a password
通过添加以下内容： Defaults:username !authenticate to your /etc/sudoers 您应该不会收到错误，但无需输入密码即可访问此用户名

Please use the "id" command and paste the output. Only if you are in admin group then you don't need password but for all other even though you have access but you need to type the sudo password. In this case sudo doesn't have a tty to ask for the password and hence the error.
请使用“id”命令并粘贴输出。仅当您在 admin 组中时，您才不需要密码，但对于所有其他人，即使您有权访问，但您需要输入 sudo 密码。在这种情况下，sudo 没有 tty 来询问密码，因此会出现错误。
One solution could be, don't use sudo only for mysql restart, instead run the entire script as sudo "sudo {your script path}" in this case sudo will have the terminal to ask for the password.
一种解决方案可能是，不要仅将 sudo 用于 mysql 重启，而是将整个脚本作为 sudo "sudo {your script path}" 运行，在这种情况下，sudo 将让终端要求输入密码。
