在您抱怨之前曾問過這個問題：我不想建立一個ssl連接。帶有MySQL的Perl模塊DBI會拋出「錯誤2026記錄：SSL連接錯誤：協議版本不匹配」
我只是想從我的客戶（Ubuntu的16.04）連接：
mysql Ver 15.1 Distrib 10.0.27-MariaDB
到舊的MySQL服務器（運行在Solaris上）：
5.5.10-log MySQL Community Server (GPL)
用Perl。
我試圖顯式禁用mysql_ssl，但它似乎沒有改變。
當我將下面的samme perl代碼連接到另一個具有實際版本的MariaDB時，沒有錯誤。 當我通過命令行連接MySQL-Client到舊的MySQL服務器時，沒有錯誤。
服務器變量被設置是這樣的：
MySQL [(none)]> show variables like '%ssl%';
+---------------+--------------------------------+
| Variable_name | Value |
+---------------+--------------------------------+
| have_openssl | YES |
| have_ssl | YES |
| ssl_ca | /etc/mysql/ssl/ca-cert.pem |
| ssl_capath | |
| ssl_cert | /etc/mysql/ssl/server-cert.pem |
| ssl_cipher | |
| ssl_key | /etc/mysql/ssl/server-key.pem |
+---------------+--------------------------------+
我的Perl代碼如下所示：
$ perl -e '
use DBI;
DBI->trace("15|CON");
my $dbh = DBI->connect("DBI:mysql:host=my_dbhost;database=test;", "test", "test",
{
PrintError => 1,
RaiseError => 1,
mysql_ssl => 0,
mysql_skip_secure_auth => 1
});
$dbh->disconnect();'
這是調試級別15輸出：用於

任何想法如何真正禁用ssl的連接？ 在此先感謝！
