Ubuntu安装mysql时候如果通过shell实现自动输入密码

Question

!/bin/bash

apt-get install -y mysql-server

通过脚本安装mysql时,如何自动输入mysql root密码

Answer 1

If you install it with root, you don’t need a password.
If you are an ordinary user and call sudo directly, you can only use methods such as expect, or change /etc/sudoers so that you do not need to enter a password.

Answer 2

mysql -u root -ppasswd
root is the username, passwd is the user’s password

Note that there should be no space between -p and password

Is this what you mean?

Answer 3

DEBIAN_FRONTEND=noninteractive apt install -y mysql-server
