我刚刚将我的 Windows Azure Hosted Ubuntu 12.04 Apache 服务器上的站点配置为使用 SSL，这些站点运行正常且重定向正确。这是我的虚拟主机配置：
<VirtualHost *:80>
ServerName site1.company.com
Redirect permanent / https://site1.company.com/
</VirtualHost>
<VirtualHost *:443>
DocumentRoot /var/www/site1
ServerName site1.company.com
Options -Indexes
DirectoryIndex login.php
SSLEngine on
SSLCertificateFile /etc/apache2/certs/company.com.crt
SSLCertificateKeyFile /etc/apache2/certs/server1.key
SSLCertificateChainFile /etc/apache2/certs/gd_bundle.crt
</VirtualHost>
所有虚拟主机的配置几乎相同。但是我在 Apache 的错误日志中看到了很多条目，这让我担心生产过程中的性能/问题。
[debug] ssl_engine_kernel.c(1866): OpenSSL: Handshake: start
[debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: before/accept initialization
[debug] ssl_engine_io.c(1908): OpenSSL: I/O error, 11 bytes expected to read on BIO#7f8f746c6ae0 [mem: 7f8f746cc0d0]

[info] [client x.x.x.x] Connection to child 0 established (server site1.company.com:443)
[info] Seeding PRNG with 656 bytes of entropy
此循环每 15 秒重复一次。我是否配置错误？所有网站均正常运行，没有错误。
答案1
这里的谜团已经解开了，这是 Azure 的负载均衡器探测。我不知道为什么 IP 地址被报告为在香港注册，但现在这很有意义了。我不得不删除并重新创建端点，以便更新端点状态并纠正问题。
如果 168.63.129.16 未在香港注册（这是访问我服务器的 IP），那么这将更容易弄清楚
