[Service]
Type=forking
#EnvironmentFile=/etc/sysconfig/httpd
PIDFile=/opt/apache2.2.34/logs/httpd.pid
ExecStart=/opt/apache2.2.34/bin/apachectl -k start
ExecStop=/opt/apache2.2.34/bin/apachectl -k stop
ExecReload=/opt/apache2.2.34/bin/apachectl  -k graceful
#ExecStop=/bin/kill -WINCH ${MAINPID}
# We want systemd to give httpd some time to finish gracefully, but still want
# it to kill httpd after TimeoutStopSec if something went wrong during the
# graceful stop. Normally, Systemd sends SIGTERM signal right after the
# ExecStop, which would kill httpd. We are sending useless SIGCONT here to give
# httpd time to finish.
#KillSignal=SIGCONT
PrivateTmp=true
LimitNOFILE=infinity
