记录下来，这帮助我解决了问题:

For the record, this helped me getting it solved:

• 检查是否可以通过程序而不是服务来启动apache，而是通过命令提示符启动！ httpd或httpd -e debug表示所有可能的错误&调试消息 如果无法启动，则可能会告诉您原因(例如php或apache配置错误)
• 如果仍然不能正常运行，请通过命令提示符安装并作为服务*运行，以查看是否还有其他问题.
  httpd -k install和httpd -k start
  检查命令提示符下的输出，error.log和Windows System Event Viewer(Windows日志/系统)

• Check if you can start apache as program, not service, but via command prompt! httpd or httpd -e debug for all possible error & debug messages If it won't start, it will probably tell you the reason (e.g. php or apache configuration error)
• If still not OK then install and run it as a service* via command prompt to see if there is anything else wrong.
  httpd -k install and httpd -k start
  Check output at command prompt, error.log and Windows System Event Viewer (Windows Logs/System)

对我来说，这使我知道我的httpd.conf中有错误. 一段时间后，我发现它与别名目录有关，可能与权限有关.更改文件夹的权限无济于事(可能是BC.我不知道默认服务使用的用户)，但是更改服务以我的用户(即admin)身份登录确实可以.

For me this learned me that I had errors in my httpd.conf. After a while I discovered it had something to do with my alias directory, probably permissions. Changing permissions on folder didn't help much (probably bc. I don't know which User the default service uses), but changing service to log on as my user (which is admin) did work.
