OCF_HEARTBEAT_APACHE(7) 					OCF resource agents					   OCF_HEARTBEAT_APACHE(7)

NAME

       ocf_heartbeat_apache - Manages an Apache Web server instance

SYNOPSIS

       apache [start | stop | status | monitor | meta-data | validate-all]

DESCRIPTION

       This is the resource agent for the Apache Web server. This resource agent operates both version 1.x and version 2.x Apache servers.

       The start operation ends with a loop in which monitor is repeatedly called to make sure that the server started and that it is operational.
       Hence, if the monitor operation does not succeed within the start operation timeout, the apache resource will end with an error status.

       The monitor operation by default loads the server status page which depends on the mod_status module and the corresponding configuration
       file (usually /etc/apache2/mod_status.conf). Make sure that the server status page works and that the access is allowed *only* from
       localhost (address 127.0.0.1). See the statusurl and testregex attributes for more details.

       See also http://httpd.apache.org/

SUPPORTED PARAMETERS

       configfile
	   The full pathname of the Apache configuration file. This file is parsed to provide defaults for various other resource agent
	   parameters.

	   (unique, optional, string, default "/etc/httpd/conf/httpd.conf")

       httpd
	   The full pathname of the httpd binary (optional).

	   (optional, string, default "/usr/sbin/httpd")

       port
	   A port number that we can probe for status information using the statusurl. This will default to the port number found in the
	   configuration file, or 80, if none can be found in the configuration file.

	   (optional, integer, no default)

       statusurl
	   The URL to monitor (the apache server status page by default). If left unspecified, it will be inferred from the apache configuration
	   file.

	   If you set this, make sure that it succeeds *only* from the localhost (127.0.0.1). Otherwise, it may happen that the cluster complains
	   about the resource being active on multiple nodes.

	   (optional, string, no default)

       testregex
	   Regular expression to match in the output of statusurl. Case insensitive.

	   (optional, string, default "exists, but impossible to show in a human readable format (try grep testregex)")

       client
	   Client to use to query to Apache. If not specified, the RA will try to find one on the system. Currently, wget and curl are supported.
	   For example, you can set this parameter to "curl" if you prefer that to wget.

	   (optional, string, no default)

       testurl
	   URL to test. If it does not start with "http", then it's considered to be relative to the Listen address.

	   (optional, string, no default)

       testregex10
	   Regular expression to match in the output of testurl. Case insensitive.

	   (optional, string, no default)

       testconffile
	   A file which contains test configuration. Could be useful if you have to check more than one web application or in case sensitive info
	   should be passed as arguments (passwords). Furthermore, using a config file is the only way to specify certain parameters.

	   Please see README.webapps for examples and file description.

	   (optional, string, no default)

       testname
	   Name of the test within the test configuration file.

	   (optional, string, no default)

       options
	   Extra options to apply when starting apache. See man httpd(8).

	   (optional, string, no default)

       envfiles
	   Files (one or more) which contain extra environment variables. If you want to prevent script from reading the default file, set this
	   parameter to empty string.

	   (optional, string, default "/etc/apache2/envvars")

       use_ipv6
	   We will try to detect if the URL (for monitor) is IPv6, but if that doesn't work set this to true to enforce IPv6.

	   (optional, boolean, default false)

SUPPORTED ACTIONS

       This resource agent supports the following actions (operations):

       start
	   Starts the resource. Suggested minimum timeout: 40s.

       stop
	   Stops the resource. Suggested minimum timeout: 60s.

       status
	   Performs a status check. Suggested minimum timeout: 30s.

       monitor
	   Performs a detailed status check. Suggested minimum timeout: 20s. Suggested interval: 10.

       meta-data
	   Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5.

       validate-all
	   Performs a validation of the resource configuration. Suggested minimum timeout: 5.

EXAMPLE

       The following is an example configuration for a apache resource using the crm(8) shell:

	   primitive p_apache ocf:heartbeat:apache 
	     op monitor depth="0" timeout="20s" interval="10"
