MySQL SSL远程连接错误:无法获取私钥

Question

我正在尝试使用SSL编写一个PHP脚本(托管在带有GoDaddy的VPS上),该脚本连接到远程MySQL数据库(托管在Amazon EC2实例上).

我生成了一些证书(根据http://dev.mysql.com/doc/refman/5.0/en/creating-ssl-certs.html)并在远程/服务器数据库上配置my.cnf,如下所示:

[mysqld]
ssl-ca      =/etc/mysql/ca-cert.pem
ssl-cert    =/etc/mysql/server-cert.pem
ssl-key     =/etc/mysql/server-key.pem

[client]
ssl-ca      =/etc/mysql/ca-cert.pem
ssl-cert    =/etc/mysql/client-cert.pem
ssl-key     =/etc/mysql/client-key.pem

配置正在远程/服务器端(即,本地运行到远程数据库的php脚本能够使用生成的SSL证书建立连接).

但是,虽然我可以在VPS上托管的PHP脚本和远程数据库之间建立不安全的连接,但是当我尝试在相同的两个系统之间建立SSL连接时出现错误.

如果我尝试使用以下命令通过命令行连接到远程数据库:

mysql -h hostIP --ssl-ca=ca-cert.pem --ssl-cert=client-cert.pem --ssl-key=client-key.pem –u ssluser –p

我收到错误:

ERROR 2026 (HY000): SSL connection error: Unable to get private key

当我尝试通过php脚本连接到服务器时,我得到了同样的错误:

<?php
 $link = mysqli_init();

 $key   = '/home/userName/etc/mysql/certs/client-key.pem' ; 
 $cert  = '/home/userName/etc/mysql/certs/client-cert.pem'; 
 $ca    = '/home/userName/etc/mysql/certs/ca-cert.pem';
 $capath = NULL;
 $cipher = NULL;

 mysqli_ssl_set ( $link , $key , $cert , $ca , $capath , $cipher );
 mysqli_real_connect ($link, $host, $user, $pass, $schema, 3306, NULL, MYSQLI_CLIENT_SSL);
?>

导致错误:

(HY000/2026): SSL connection error: Unable to get private key

我已根据(forums.mysql.com/read.php?11,400856,401127)尝试修复,但进行此更改会导致"分段错误".

有没有我错过的一步？我究竟做错了什么？

Answer 1

决议:

删除了client-key.pem密码

openssl rsa -in client-key.pem -out client-key2.pem

根据本网站的说明.

我变了

$key   = '/home/userName/etc/mysql/certs/client-key2.pem' ; 

和

mysql -h hostIP --ssl-ca=ca-cert.pem --ssl-cert=client-cert.pem --ssl-key=client-key2.pem –u ssluser –p

但不是

[client]
ssl-key     =/etc/mysql/client-key.pem
