【问题描述】:
我正在尝试在 MariaDB 10.6.3 服务器(Rocky Linux)中启用文件密钥管理加密。我正在使用 open ssl 生成密钥文件。我已遵循本指南https://mariadb.com/resources/blog/mariadb-encryption-tde-using-mariadbs-file-key-management-encryption-plugin/
echo \"1;\"$(openssl rand -hex 32) > /etc/mysql/encryption/keyfile
openssl rand -hex 128 > /etc/mysql/encryption/keyfile.key
使用生成加密文件时
openssl enc -aes-256-cbc -md sha1 -pass file:/etc/mysql/encryption/keyfile.key -in /etc/mysql/encryption/keyfile -out /etc/mysql/encryption/keyfile.enc
我收到警告
*** WARNING : deprecated key derivation used.
Using -iter or -pbkdf2 would be better.
由于上面的代码产生了一个警告,我用
openssl enc -aes-256-cbc -md sha512 -pbkdf2 -iter 100000
-pass file:/etc/mysql/encryption/keyfile.key -in /etc/mysql/encryption/keyfile -out /etc/mysql/encryption/keyfile.enc
这是我在 server.cnf 中添加的配置
#File Key Management Plugin
plugin_load_add = file_key_management
file_key_management_filename = /etc/mysql/encryption/keyfile.enc
file_key_management_filekey = FILE:/etc/mysql/encryption/keyfile.key
file_key_management_encryption_algorithm = AES_CTR
# InnoDB Encryption Setup
innodb_encrypt_tables = ON
innodb_encrypt_log = ON
innodb_encrypt_temporary_tables = ON
innodb_encryption_threads = 4
innodb_encryption_rotation_iops = 2000
# Temp & Log Encryption
encrypt_tmp_disk_tables = ON
encrypt_tmp_files = ON
encrypt_binlog = ON
aria_encrypt_tables = ON
保存配置后,当我尝试重新启动 MariaDB 时,它无法启动。 MariaDB 状态产生
[ERROR] mariadbd: Cannot decrypt /etc/mysql/encryption/keyfile.enc. Wrong key?
[ERROR] Plugin \'file_key_management\' init function returned error.
[ERROR] Plugin \'file_key_management\' registration as a ENCRYPTION failed.
[ERROR] InnoDB: cannot enable encryption, encryption plugin is not available
[ERROR] Plugin \'InnoDB\' init function returned error.

systemd[1]: mariadb.service: Failed with result \'exit-code\'.
systemd[1]: Failed to start MariaDB 10.6.3 database server.
我检查了 /var/lib/mysql/ 并且 file_key_management.so 文件可用。
我确定添加-pbkdf2 -iter 100000 是问题所在。
谁能告诉我哪里出了问题?
