Mysql 通过 userdata 在 aws ec2 实例上安装

Question

I am giving this script as a userdata in an ec2 instance to install and setup mysql. The code runs fine manually but when given to ec2 instance as userdata it doesnot creates the database or user.

#!/bin/bash
sudo yum -y update
sudo yum -y install aspell aspell-en httpd24 mysql mysql-server php56 php56-cli php56-gd php56-intl php56-mbstring php56-mysqlnd php56-opcache php56-pdo php56-soap php56-xml php56-xmlrpc php56-pspell --skip-broken
sudo yum list installed
sudo /sbin/chkconfig httpd on
sudo /sbin/chkconfig mysqld on  
sudo /sbin/service httpd start
sudo /sbin/service mysqld start
sudo mysqladmin -u root password '123a'
sudo mysql -u root -p123a
CREATE DATABASE db;
CREATE USER '1234'@'localhost' IDENTIFIED BY '123a';
GRANT FILE ON *.* TO '1234'@'localhost';
FLUSH PRIVILEGES;

Mysql version: 5.7.28

Answer 1

Your grant command is not right, nowadays it is simply without password

sudo mysql -u root -p123a -e  "CREATE DATABASE db DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;use db;create user 'db'@'localhost' identified by '123a';  grant all on testdb.* to 'db';GRANT ALL ON db.* TO ' db '@'localhost';GRANT ALL ON db.* TO ' db '@'%';FLUSH PRIVILEGES;"
