NAME

ocf_heartbeat_varnish - Manage a Varnish instance

SYNOPSIS

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

DESCRIPTION

The Varnish Resource Agent can manage several varnishd instances throughout the cluster. It does so by creating a unique PID file and requires a unique listen address and name for each instance.

SUPPORTED PARAMETERS

config The VCL configuration file that Varnish should manage, for example "/etc/varnish/default.vcl". (unique, required, string, no default) name Override the name of the instance that should be given to Varnish (defaults to the resource identifier). (unique, optional, string, default "RESOURCE_ID") pid Write the process's PID to the specified file. The default will include the specified name, i.e.: "/var/run/varnish_production.pid". Unlike what this help message shows, it is most likely not necessary to change this parameter. (unique, optional, string, default "/var/run/varnishd_RESOURCE_ID.pid") listen_address Listen on this address:port, for example "192.168.1.1:80" (unique, optional, string, default "0.0.0.0:80") mgmt_address Provide a management interface, for example "127.0.0.1:2222" (unique, required, string, no default) ttl Specify a hard minimum time to live for cached documents. (optional, integer, default 600) varnish_user Specify the name of an unprivileged user to which the child process should switch before it starts accepting connections. (optional, string, default "varnish") varnish_group Specify the name of an unprivileged group to which the child process should switch before it starts accepting connections. (optional, string, default "varnish") backend_type Use the specified storage backend. Valid options are 'malloc' for memory and 'file' for a file backend. (optional, string, default "malloc") backend_size Specify the size of the backend. For example "1G". (optional, string, default "1G") backend_file Specify the backend filename if you use backend_type file. For example /var/lib/varnish/mybackend.bin (unique, optional, string, default "/var/lib/varnish/RESOURCE_ID.bin") threads_pools Number of worker thread pools. Each pool has the minimum, maximum and timeout values configured in the thread_pool_min, thread_pool_max and thread_pool_timeout parameters (optional, string, default "2") thread_pool_min Start at least min but no more than max worker threads with the specified idle timeout in each pool. (optional, string, default "100") thread_pool_max Start at least min but no more than max worker threads with the specified idle timeout in each pool. (optional, string, default "3000") thread_pool_timeout Start at least min but no more than max worker threads with the specified idle timeout in each pool. (optional, string, default "120") client_binary This is used to control Varnish via a CLI. It's currently only used to check the status of the running child process. (optional, string, default "varnishadm") maxfiles Maximum number of open files (for ulimit -n) (optional, string, default "131072") max_locked_memory Locked shared memory limit (for ulimit -l) (optional, string, default "82000") secret Path to a file containing a secret used for authorizing access to the management port. (optional, string, default "/etc/varnish/secret")

SUPPORTED ACTIONS

This resource agent supports the following actions (operations): start Starts the resource. Suggested minimum timeout: 20. stop Stops the resource. Suggested minimum timeout: 20. monitor Performs a detailed status check. Suggested minimum timeout: 20. Suggested interval: 10. status Performs a status check. Suggested minimum timeout: 20. 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: 20.

EXAMPLE CRM SHELL

The following is an example configuration for a varnish resource using the crm(8) shell: primitive p_varnish ocf:heartbeat:varnish \ params \ config=string \ mgmt_address=string \ op monitor timeout="20" interval="10" depth="0"

EXAMPLE PCS

The following is an example configuration for a varnish resource using pcs(8) pcs resource create p_varnish ocf:heartbeat:varnish \ config=string \ mgmt_address=string \ op monitor timeout="20" interval="10" depth="0"
