mysql を自動的にインストールするための bash スクリプトを作成しようとしています。mysql に付属するユーティリティ「mysql_secure_installation」があります。これは、mysql のインストールを保護するために実行できます。これはシェル スクリプトで、呼び出されると複数のインタラクティブな入力を受け取ります。ユーティリティスクリプトを実際に変更せずに、これらの値をスクリプトに自動的に渡すにはどうすればよいですか。EOF マーカーについては知っていますが、ここで使用できるかどうかはわかりません。前もって感謝します

このユーティリティ スクリプトは、一連の質問をします。単一のプロンプトの場合、ヒアドキュメントを使用できますが、入力を後続のプロンプトに渡すにはどうすればよいですか。実行はこんな感じ

venkatesh@venki-ws003:~/jit/jambuvaan-app$ mysql_secure_installation 




NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!


In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

You already have a root password set, so you can safely answer 'n'.

Change the root password? [Y/n] n
 ... skipping.

By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] Y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] Y
 ... Success!

By default, MySQL comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] Y
 - Dropping test database...
ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist
 ... Failed!  Not critical, keep moving...
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] Y
 ... Success!

Cleaning up...

使用できる期待スクリプトは次のとおりです。

#!/usr/bin/expect -f

set timeout 2 
set password ""

spawn mysql_secure_installation

expect {
    timeout { exit 1; }
    "Enter current password for*"
}

send "$password\r"

expect {
    timeout { exit 1; }
    "Set * password? *"
}

send "n\r"

expect {
    timeout { exit 1; }
    "Remove anonymous users? *"
}

send "Y\r"

expect {
    timeout { exit 1; }
    "Disallow root login remotely? *"
}

send "Y\r"

expect {
    timeout { exit 1; }
    "Remove test database and access to it? *"
}

send "Y\r"

expect {
    timeout { exit 1; }
    "Reload privilege tables now? *"
}

send "Y\r"

expect {
    timeout { exit 1; }
    "Cleaning up..."
}

UNIX 形式でファイルに保存し、実行しますexpect script.exp。

これらの「EOF マーカー」はヒアドキュメントと呼ばれます。また、プログラム/スクリプトが標準入力から入力を取得する場合は、それらを使用できます (ほとんどの場合)。

some_command << EOF
do this
do that
EOF
