在OS X El Capitan上更改Apache DocumentRoot后连接被拒绝

我正在使用OS X El Capitan，并更改了Apache2配置文件/etc/Apache2/http.conf以重新定位文件路径

我修改了 DocumentRoot/Library/WebServer/Documents 到 DocumentRoot~/Dropbox/myweb，以及

<Directory "Library/WebServer/Documents"> 

并将文件夹更改为

sudo chmod 777 ~/Dropbox/myweb

我重新启动了Apache，然后无法再连接。歌剧还我

铬还我

ERR_CONNECTION_REFUSED

我不确定是否遗漏了任何步骤？

尝试运行apachectl configtest以确定您的配置是否都正常。这里出现了同样的问题，configtest告诉我httpd-userdir.conf文件中有问题。

我的configtest说语法正常。。。还有其他想法吗？
