6 ocf_heartbeat_nginx - Manages an Nginx web/proxy server instance
7
9 nginx [start | stop | status | monitor | meta-data | validate-all]
10
12 This is the resource agent for the Nginx web/proxy server. This
13 resource agent does not monitor POP or IMAP servers, as we don't know
14 how to determine meaningful status for them.
15 The start operation ends with a loop in which monitor is repeatedly
17 called to make sure that the server started and that it is operational.
18 Hence, if the monitor operation does not succeed within the start
19 operation timeout, the nginx resource will end with an error status.
20 The default monitor operation will verify that nginx is running.
22 The level 10 monitor operation by default will try and fetch the
24 /nginx_status page - which is commented out in sample nginx
25 configurations. Make sure that the /nginx_status page works and that
26 the access is restricted to localhost (address 127.0.0.1) plus whatever
27 places _outside the cluster_ you want to monitor the server from. See
28 the status10url and status10regex attributes for more details.
29 The level 20 monitor operation will perform a more complex set of tests
31 from a configuration file.
32 The level 30 monitor operation will run an external command to perform
34 an arbitrary monitoring operation.
35
37 configfile
38 The full pathname of the Nginx configuration file. This file is
39 parsed to provide defaults for various other resource agent
40 parameters.
41 (unique, optional, string, no default)
43 httpd
45 The full pathname of the httpd binary (optional).
46 (optional, string, default "/usr/sbin/httpd")
48 port
50 A port number that we can probe for status information using the
51 statusurl. This will default to the port number found in the
52 configuration file, or 80, if none can be found in the
53 configuration file.
54 (optional, integer, no default)
56 status10url
58 The URL to monitor (the nginx server status page by default) when
59 given a level 10 monitor operation. If left unspecified, it will be
60 inferred from the nginx configuration file, or defaulted to
61 /nginx_status.
62 If you set this, make sure that it succeeds *only* from the
64 localhost (127.0.0.1) and no other cluster nodes. Otherwise, the
65 cluster software may complain about it being active on multiple
66 nodes.
67 (optional, string, no default)
69 status10regex
71 Regular expression to match in the output of status10url. Case
72 insensitive.
73 (optional, string, default "Reading: [0-9]+ Writing: [0-9]+
75 Waiting: [0-9]+")
76 testclient
78 Client to use to query to Nginx for level 10 and level 20 tests. If
79 not specified, the RA will try to find one on the system.
80 Currently, wget and curl are supported, with curl being preferred.
81 For example, you can set this parameter to "wget" if you prefer
82 that to curl.
83 (optional, string, no default)
85 test20url
87 URL to test. If it does not start with "http", then it's considered
88 to be relative to the document root address.
89 (optional, string, no default)
91 test20regex
93 Regular expression to match in the output of test20url. Case
94 insensitive.
95 (optional, string, no default)
97 test20conffile
99 A file which contains a more complex test configuration. Could be
100 useful if you have to check more than one web application or in
101 case sensitive info should be passed as arguments (passwords).
102 Furthermore, using a config file is the only way to specify certain
103 parameters.
104 Please see README.webapps for examples and file description.
106 (optional, string, no default)
108 test20name
110 Name of the test within the test configuration file.
111 (optional, string, no default)
113 external_monitor30_cmd
115 Command string to run which implements level 30 monitoring.
116 (optional, string, no default)
118 options
120 Extra options to apply when starting nginx.
121 (optional, string, no default)

129 stop
131 Stops the resource. Suggested minimum timeout: 60s.
132 reload
134 Suggested minimum timeout: 40s.
135 status
137 Performs a status check. Suggested minimum timeout: 30s.
138 monitor
140 Performs a detailed status check. Suggested minimum timeout: 30s.
141 Suggested interval: 10s.
142 monitor
144 Performs a detailed status check. Suggested minimum timeout: 30s.

149 monitor
151 Performs a detailed status check. Suggested minimum timeout: 60s.
152 meta-data
154 Retrieves resource agent metadata (internal use only). Suggested

162 The following is an example configuration for a nginx resource using
163 the crm(8) shell:
164 primitive p_nginx ocf:heartbeat:nginx \
166 op monitor timeout="30s" depth="0" interval="10s" \
167 op monitor timeout="30s" depth="10" interval="30s" \
168 op monitor timeout="45s" depth="20" \
169 op monitor timeout="60s" depth="30"
170
172 The following is an example configuration for a nginx resource using
173 pcs(8)
174 pcs resource create p_nginx ocf:heartbeat:nginx \
176 op monitor timeout="30s" OCF_CHECK_LEVEL="0" interval="10s" \
177 op monitor timeout="30s" OCF_CHECK_LEVEL="10" interval="30s" \
178 op monitor timeout="45s" OCF_CHECK_LEVEL="20" \
179 op monitor timeout="60s" OCF_CHECK_LEVEL="30"
