вообще-то есть такая замечательная вещь как sudo service apache2 graceful
graceful: Gracefully restarts the Apache daemon by sending it a SIGUSR1. If the daemon is not running, it is started. This differs from a normal restart in that currently open connections are not aborted. A side effect is that old log files will not be closed immediately. This command automatically checks the configuration files via configtest before initiating the restart to make sure Apache doesn't die.
