[error] Unable to configure RSA server private key错误解决方法

现象:

#service apache2 restart

 * Restarting web server apache2                                                Apache/2.2.16 mod_ssl/2.2.16 (Pass Phrase Dialog)

Some of your private key files are encrypted for security reasons.

In order to read them you have to provide the pass phrases.

Server xdty.org:443 (RSA)

Enter pass phrase:

OK: Pass Phrase Dialog successful.

                                                                         [ OK ]

解决如下：

应该是因为key有密码导致的，进入key目录，通过以下命令去除密码

openssl rsa -in my-server.key -out my-server.key

重启服务即可
