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
