Apache status

How to check Apache status in command line: started or stopped?

Other Linux distributions has more options for services. For example, /etc/rc.d/httpd status. As i see Arch can only stop or start

Maybe give "netstat -ta" a go for daemon status.
If you only want to see if apache is listening, "netstat -ta |grep http" instead of the list.

if [ ! -z "$(pgrep httpd)" ]; then 
  echo "apache is running"
else 
  echo "apache is not running"
fi

Thanks, cactus

How Arch knows about services (from /etc/rc.d) that it must stop (for example) on shutdown?

from /etc/rc.d/functions

add_daemon() {
        [ -d /var/run/daemons ] || mkdir -p /var/run/daemons
        touch /var/run/daemons/$1
}

So you could look in /var/run/daemons, but that won't help you if the process has crashed (it would have an entry but not be running).

Is there a difference between
- run Apache via '/etc/rc.d/httpd start'
- run Apache via 'apachectl start'
(except that apachectl don't create /var/run/daemons/httpd)?

cat /etc/rc.d/httpd

That shows you what happens when you use the init script.

Thanks, cactus.

Also i found, that apachectl is a bash-script too It has command-line option status (inside, not in help), it requires lynx and produce strange output...

# apachectl status
                               Object not found!

   The requested URL was not found on this server. If you entered the URL
   manually please check your spelling and try again.

   If you think this is a server error, please contact the [1]webmaster.

Error 404

   1. mailto:admin@server
   2. http://localhost/

So better way to check Apache status is
- to use script /etc/rc.d/httpd to start/stop
- and check presence of file /var/run/daemons/httpd for status

From Apache manual:

In order to stop or restart Apache, you must send a signal to the running httpd processes. ... You will notice many httpd executables running on your system, but you should not send signals to any of them except the parent, whose pid is in the PidFile. That is to say you shouldn't ever need to send signals to any process except the parent. ...
To send a signal to the parent you should issue a command such as:
kill -TERM `cat /usr/local/apache2/logs/httpd.pid`

/usr/local/apache2/logs/httpd.pid = /var/run/httpd.pid in Arch
just check existence of file /var/run/httpd.pid
