.SH NAME
apache2ctl \- Apache HTTP server control interface
.SH SYNOPSIS
When acting in SysV init mode, apache2ctl takes simple, one-word commands,
defined below.
.PP
.B apachectl
.I command
.PP
.B apache2ctl
.I command
.PP
When acting in pass-through mode, apache2ctl can take all the arguments available
for the httpd binary.

.PP
.SH DESCRIPTION
.B apache2ctl
is a front end to the Apache HyperText Transfer Protocol (HTTP)
server. It is designed to help the administrator control the
functioning of the Apache
.B apache2
daemon.
.PP
.B NOTE:
The default Debian configuration requires the environment variables
.BR APACHE_RUN_USER ,
.BR APACHE_RUN_GROUP ,
and
.B APACHE_PID_FILE
to be set in
.BR /etc/apache2/envvars .
.PP
The
.B apache2ctl
script returns a 0 exit value on success, and >0 if an error
occurs. For more details, view the comments in the script.
.PP
.SH OPTIONS
The \fIcommand\fP can be any one or more of the following options:
.TP 14
.BI start
Start the Apache daemon. Gives an error if it is already running.
.TP
.BI stop
Stops the Apache daemon.
.TP
.BI restart
Restarts the Apache daemon by sending it a SIGHUP. If the daemon
is not running, it is started.
This command automatically checks the configuration files via
.BI configtest
before initiating the restart to to catch the most obvious errors.
However, it is still possible for the daemon to die because of problems
with the configuration.
.TP
.BI fullstatus
Displays a full status report from
.B mod_status.
For this to work, you need to have mod_status enabled on your server
and a text-based browser such as \fIlynx\fP available on your system. The
URL used to access the status report can be set by setting the
.B APACHE_STATUSURL
variable in
.BR /etc/apache2/envvars .
.TP
.BI status
Displays a brief status report. Similar to the fullstatus option,
except that the list of requests currently being served is omitted.
.TP
.BI 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 means that if used in a log rotation script, a substantial delay may be
necessary to ensure that the old log files are closed before processing them.
This command automatically checks the configuration files via apache2ctl
configtest before initiating the restart to to catch the most obvious errors.
However, it is still possible for the daemon to die because of problems with
the configuration.
.TP
.BI graceful-stop
Gracefully stops the Apache httpd daemon.
This differs from a normal stop in that currently open connections are not
aborted.
A side effect is that old log files will not be closed immediately.
.TP
.BI configtest
Run a configuration file syntax test. It parses the configuration
files and either reports
.B "Syntax Ok"
or information about the particular syntax error. This test does not catch
all errors.
.TP
.BI help
Displays a short help message.
.TP
The following option was available in earlier versions but has been removed.
.TP
.BI startssl
To start httpd with SSL support, you should edit your configuration file to
include the relevant directives and then use the normal apache2ctl start.
.SH ENVIRONMENT
The behaviour of
.B apache2ctl
can be influenced with these environment variables:
.BR APACHE_HTTPD ,
.BR APACHE_LYNX ,
.BR APACHE_STATUSURL ,
.BR APACHE_ULIMIT_MAX_FILES ,
.BR APACHE_RUN_DIR ,
.BR APACHE_LOCK_DIR ,
.BR APACHE_RUN_USER ,
.BR APACHE_ARGUMENTS ,
.BR APACHE_ENVVARS .
See the comments in the script for details.
These variables (except
.BR APACHE_ENVVARS )
can be set in
.BR /etc/apache2/envvars .
