啟用 MariaDB SSL

啟用 MariaDB SSL

我必須使我的 MariaDB 身份驗證比預設身份驗證更安全。我嘗試為此設置 SSL 支持，但在這裡只找到了一個舊的操作方法：

如何在 Ubuntu 上啟用 MySQL SSL

我遵循了它，但是檢查後我得到了這個：

MariaDB [(none)]> show variables like "%ssl%";
+---------------+----------------------------+
| Variable_name | Value                      |
+---------------+----------------------------+
| have_openssl  | NO                         |
| have_ssl      | DISABLED                   |
| ssl_ca        | /etc/mysql/ca-cert.pem     |
| ssl_capath    |                            |
| ssl_cert      | /etc/mysql/server-cert.pem |
| ssl_cipher    |                            |
| ssl_crl       |                            |
| ssl_crlpath   |                            |
| ssl_key       | /etc/mysql/server-key.pem  |
+---------------+----------------------------+
9 rows in set (0.00 sec)

MariaDB [(none)]> \s
...
SSL: not in use
...

這個原始碼是2011年寫的。當我生成時.pems沒有錯誤。我的/var/log/mysql/error.log文件是空的。

你有什麼想法？

要在 mariadb 中啟用 ssl，您的版本需要使用 ssl ( have_ssl | DISABLED) 進行編譯，並且需要在 mysql 配置中啟用它：

# grep -Ri ssl /etc/mysql/my.cnf
ssl = true
ssl-ca = /etc/mysql/cacert.pem
ssl-cert = /etc/mysql/server-cert.pem
ssl-key = /etc/mysql/server-key.pem

重啟後或者mysql進程ssl應該被啟用。

邊註

這個答案來自另一個問題幫助我擺脫了這個錯誤：

ERROR 2026 (HY000): SSL connection error: tlsv1 alert unknown ca

答案2

我創建了 Ubuntu 18.04.3 憑證授權單位。驗證了一切。根、證書、鑰匙鏈有效。

MariaDB [(none)]>

我按照 CA 的線上流程創建了 MariaDB SSL 金鑰。

我這樣做是my.cnf為了讓鑰匙出現在上面。/etc/mysql/mariadb.cnf裡面有鑰匙。我已經安裝了 Mariadb 儲存庫來進行更新。

這是my.cnf：

[mysqld]
ssl = true
ssl-ca          = /etc/mysql/ssl/ca-cert.pem
ssl-cert         = /etc/mysql/ssl/mariadb-cert.pem
ssl-key          = /etc/mysql/ssl/mariadb-key.pem
log_error=/var/log/mysql/mysql_error.log
ssl-cipher=DHE-RSA-AES256-SHA


grep -Ri ssl /etc/mysql/my.cnf
ssl = true
ssl-ca          = /etc/mysql/ssl/ca-cert.pem
ssl-cert         = /etc/mysql/ssl/mariadb-cert.pem
ssl-key          = /etc/mysql/ssl/mariadb-key.pem
ssl-cipher=DHE-RSA-AES256-SHA

ssl-cipher entry can be removed.
