我正在设置Drupal Open Atrium，并在configuration中途收到一个错误：
Clean Url必须可用，并且可以使用OpenAtrium。
https://www.drupal.org/docs/7/configuring-clean-urls/enable-clean-urls告诉我运行sudo a2enmod rewrite ，这发生：
Enabling module rewrite. To activate the new configuration, you need to run: service apache2 restart
但是当我然后运行sudo service apache2 restart我得到以下错误：
Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details.
systemctl status apache2.service返回：

问题用a2dismod rewrite ，然后我回到了我开始的地方。
我的/etc/apache2/mods-enabled/rewrite.load看起来像这样，如果这是麻烦。
LoadModule rewrite_module modules/mod_rewrite.so
我怎样才能得到重写MOD与Apache的工作？
这终于通过使用sudo apache2ctl graceful和跟随错误消息中的文件链接来解决，例如：
apache2: Syntax error on line 140 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/mods-enabled/rewrite.load: LoadModule takes two arguments, a module name and the name of a shared object file to load it from Action 'graceful' failed. The Apache error log may have more information.
最后，我从Drupalbuild议的rewrite.load中删除了AddModule mod_rewrite.c ，并将链接从modules/mod_rewrite.so更改为/usr/lib/apache2/modules/mod_rewrite.so ， （用sudo find / -name mod_rewrite.so ）
然后我重新启动apache，一切正常！
