启动的Apache过程中，有时候因为监听端口冲突，会报错而启动失败，类似的错误信息如下：
17:09:04 [Apache] Error: Apache shutdown unexpectedly.
17:09:04 [Apache] This may be due to a blocked port, missing dependencies,
17:09:04 [Apache] improper privileges, a crash, or a shutdown by another method.
17:09:04 [Apache] Press the Logs button to view error logs and check
17:09:04 [Apache] the Windows Event Viewer for more clues
17:09:04 [Apache] If you need more help, copy and post this
17:09:04 [Apache] entire log window on the forums
17:09:12 [Apache] Problem detected!
17:09:12 [Apache] Port 443 in use by ""E:\Program Files (x86)\VMware Workstation\vmware-hostd.exe" -u "C:\ProgramData\VMware\hostd\config.xml"" with PID 2952!
17:09:12 [Apache] Apache WILL NOT start without the configured ports free!
17:09:12 [Apache] You need to uninstall/disable/reconfigure the blocking application
17:09:12 [Apache] or reconfigure Apache and the Control Panel to listen on a different port
对于这个错误，解决方法是更换监听的端口，点击进行Apache配置文件httpd-ssl.conf
修改监听的端口
#
# When we also provide SSL we have to listen to the
# standard HTTP port (see above) and to the HTTPS port
# Listen 4450
