OCF_HEARTBEAT_NGINX(7)	       OCF resource agents	  OCF_HEARTBEAT_NGINX(7)

NAME
     ocf_heartbeat_nginx - Manages an Nginx web/proxy server instance

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

DESCRIPTION
     This  is  the  resource agent for the Nginx web/proxy server. This resource
     agent does not monitor POP or IMAP servers, as we don't know how to  deter-
     mine meaningful status for them.

     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 nginx resource will end with an error status.

     The default monitor operation will verify that nginx is running.

     The level 10 monitor operation by default	will  try  and	fetch  the  /ng-
     inx_status  page  -  which is commented out in sample nginx configurations.
     Make sure that the /nginx_status page works and  that  the  access  is  re-
     stricted to localhost (address 127.0.0.1) plus whatever places _outside the
     cluster_  you want to monitor the server from. See the status10url and sta-
     tus10regex attributes for more details.

     The level 20 monitor operation will perform a more  complex  set  of  tests
     from a configuration file.

     The  level  30 monitor operation will run an external command to perform an
     arbitrary monitoring operation.

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

	 (unique, optional, string, no default)

     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 sta-
	 tusurl. 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)

     status10url
	 The URL to monitor (the nginx server status page by default) when given
	 a level 10 monitor operation. If left unspecified, it will be	inferred
	 from the nginx configuration file, or defaulted to /nginx_status.

	 If  you  set this, make sure that it succeeds *only* from the localhost
	 (127.0.0.1) and no other cluster nodes. Otherwise, the cluster software
	 may complain about it being active on multiple nodes.

	 (optional, string, no default)

     status10regex
	 Regular expression to match in the output of status10url. Case insensi-
	 tive.

	 (optional, string, default "Reading: [0-9]+  Writing:	[0-9]+	Waiting:
	 [0-9]+")

     testclient
	 Client to use to query to Nginx for level 10 and level 20 tests. If not
	 specified,  the  RA will try to find one on the system. Currently, wget
	 and curl are supported, with curl being preferred. For example, you can
	 set this parameter to "wget" if you prefer that to curl.

	 (optional, string, no default)

     test20url
	 URL to test. If it does not start with "http", then it's considered  to
	 be relative to the document root address.

	 (optional, string, no default)

     test20regex
	 Regular  expression  to match in the output of test20url. Case insensi-
	 tive.

	 (optional, string, no default)

     test20conffile
	 A file which contains a more complex test configuration. Could be  use-
	 ful  if you have to check more than one web application or in case sen-
	 sitive info should be passed as arguments (passwords). Furthermore, us-
	 ing a config file is the only way to specify certain parameters.

	 Please see README.webapps for examples and file description.

	 (optional, string, no default)

     test20name
	 Name of the test within the test configuration file.

	 (optional, string, no default)

     external_monitor30_cmd
	 Command string to run which implements level 30 monitoring.

	 (optional, string, no default)

     options
	 Extra options to apply when starting nginx.

	 (optional, string, no default)

	   op monitor timeout="30s" depth="10" interval="30s" \
	   op monitor timeout="45s" depth="20" \
	   op monitor timeout="60s" depth="30"

EXAMPLE PCS
     The following is an example configuration for a nginx resource using pcs(8)

	 pcs resource create p_nginx ocf:heartbeat:nginx \
	   op monitor timeout="30s" OCF_CHECK_LEVEL="0" interval="10s" \
	   op monitor timeout="30s" OCF_CHECK_LEVEL="10" interval="30s" \
	   op monitor timeout="45s" OCF_CHECK_LEVEL="20" \
