Automatisez l'installation sécurisée de mysql en utilisant un script shell

Essayez ceci tel quel, il semble qu'il y ait un problème avec ( et le pipe | donc j'ai dû les échapper.

Code source

#!/bin/bash

      MYSQL=$(grep 'temporary password' /var/log/mysqld.log | awk '{print $11}')
      MYSQL_ROOT_PASSWORD="test@123"

      SECURE_MYSQL=$(expect -c "

      set timeout 10
      spawn mysql_secure_installation

      expect "Enter password for user root:"
      send "$MYSQL\r"

      expect "Change the password for root ?\(Press y\|Y for Yes, any other key for No\) :"
      send "y\r"

      expect "New password:"
      send "$MYSQL_ROOT_PASSWORD\r"

      expect "Re-enter new password:"
      send "$MYSQL_ROOT_PASSWORD\r"

      expect "Do you wish to continue with the password provided?\(Press y\|Y for Yes, any other key for No\) :"
      send "y\r"

      expect "Remove anonymous users?\(Press y\|Y for Yes, any other key for No\) :"
      send "y\r"

      expect "Disallow root login remotely?\(Press y\|Y for Yes, any other key for No\) :"
      send "y\r"

      expect "Remove test database and access to it?\(Press y\|Y for Yes, any other key for No\) :"
      send "y\r"

      expect "Reload privilege tables now?\(Press y\|Y for Yes, any other key for No\) :"
      send "y\r"

      expect eof
      ")

      echo "$SECURE_MYSQL"

VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?

Le script ci-dessous a fonctionné pour moi.
