Discription
NAME
apache2ctl - Apache HTTP server control interface
SYNOPSIS
When acting in SysV init mode, apache2ctl takes simple, one-word commands, defined below.
apachectl command
apache2ctl command
When acting in pass-through mode, apache2ctl can take all the arguments available for the httpd
binary.
apachectl [httpd-argument]
apache2ctl [httpd-argument]
DESCRIPTION
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 apache2 daemon.
NOTE: The default Debian configuration requires the environment variables APACHE_RUN_USER,
APACHE_RUN_GROUP, and APACHE_PID_FILE to be set in /etc/apache2/envvars.
The apache2ctl script returns a 0 exit value on success, and >0 if an error occurs. For more
details, view the comments in the script.
OPTIONS
The command can be any one or more of the following options:
start Start the Apache daemon. Gives an error if it is already running.
stop Stops the Apache daemon.
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 con‐
figtest before initiating the restart to to catch the most obvious errors. How‐
ever, it is still possible for the daemon to die because of problems with the con‐
figuration.
fullstatus Displays a full status report from mod_status. For this to work, you need to have
mod_status enabled on your server and a text-based browser such as lynx available on
your system. The URL used to access the status report can be set by setting the
APACHE_STATUSURL variable in /etc/apache2/envvars.
status Displays a brief status report. Similar to the fullstatus option, except that the
list of requests currently being served is omitted.
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.
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.
configtest Run a configuration file syntax test. It parses the configuration files and either
reports Syntax Ok or information about the particular syntax error. This test does
not catch all errors.
help Displays a short help message.
The following option was available in earlier versions but has been removed.
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.
ENVIRONMENT
The behaviour of apache2ctl can be influenced with these environment variables: APACHE_HTTPD,
APACHE_LYNX, APACHE_STATUSURL, APACHE_ULIMIT_MAX_FILES, APACHE_RUN_DIR, APACHE_LOCK_DIR,
APACHE_RUN_USER, APACHE_ARGUMENTS, APACHE_ENVVARS. See the comments in the script for details.
These variables (except APACHE_ENVVARS) can be set in /etc/apache2/envvars.
