Thing to do after updating to latest OS

After updating the OSX to the latest one.

My webserver didn’t recognize my previously customized VHOST.
Turn out,the update saved those config as ~previous.
So, I just need to restore it back and it is online again.

Thanks.

nb-namran:/etc/apache2$ diff httpd.conf httpd.conf~previous

after restore the config,you may need to restart the apache2 server with the following command.

apachectl restart
