SYNOPSIS

       pcsd
       pcsd --version [--full]

DESCRIPTION

       Daemon for controlling and configuring pacemaker/corosync clusters via pcs.

       --version
              Print pcsd version information. List pcsd capabilities if --full is specified.

ENVIRONMENT

   Network and SSL/TLS Settings
       PCSD_BIND_ADDR=<string>
              List of IP addresses pcsd should bind to delimited by ',' character.

       PCSD_PORT=<string>
              Port on which pcsd should be available.

       PCSD_SSL_OPTIONS=<string>
              SSL/TLS  options  delimited  by  ',' character. This is usually used to set SSL/TLS
              protocols accepted by pcsd. List of valid options can be obtained by running:  ruby
              -e 'require "openssl"; puts OpenSSL::SSL.constants.grep /^OP_/'

       PCSD_SSL_CIPHERS=<string>
              SSL/TLS ciphers accepted by pcsd.

   Web UI Settings
       PCSD_DISABLE_GUI=<boolean>
              Set to true to disable web UI frontend in pcsd.

       PCSD_SESSION_LIFETIME=<integer>
              Web UI session lifetime in seconds.

   Proxy Settings
       See ENVIRONMENT section in curl(1) man page for more details.

       https_proxy=<string>, HTTPS_PROXY=<string>
              Proxy server address for node to node communication.

       all_proxy=<string>, ALL_PROXY=<string>
              Proxy server address for node to node communication.

       no_proxy=<string>, NO_PROXY=<string>
              List of hostnames for which proxy is not used.

   Miscellaneous Settings
       PCSD_DEBUG=<boolean>
              Set to true for advanced pcsd debugging information.

       PCSD_RESTART_AFTER_REQUESTS=<integer>
              Number  of  requests after which the Ruby server will be restarted to reduce memory
              footprint. To disable restarts, set 0, other numbers lower than 50 are  interpreted
              as 50. Invalid values are ignored and the default (200) is set instead.

FILES

       All  files  described in this section are located in /var/lib/pcsd/. They are not meant to
       be edited manually unless said otherwise.

   cfgsync_ctl
       This JSON file controls  pcsd  and  cluster  configuration  files  synchronization  across
       cluster nodes which pcsd is doing automatically in the background. This file can be safely
       edited manually.
       Example:
       {
         "file_backup_count": 50,
         "thread_disabled": false,
         "thread_interval": 600,
         "thread_interval_previous_not_connected": 60,
         "thread_paused_until": 1487780453
       }

       file_backup_count
              How many backup files should be kept for each synchronized file.

       thread_disabled
              Set this to true to completely disable the synchronization.

       thread_interval
              How often in seconds should pcsd ask other nodes if  the  synchronized  files  have
              changed.

       thread_interval_previous_not_connected
              How  often  in  seconds  should pcsd ask other nodes if the synchronized files have
              changed if during the previous attempt pcsd was unable to connect to at  least  two
              nodes.

       thread_paused_until
              Disable the synchronization until the set unix timestamp.

   known-hosts
       This  JSON  file  stores information about hosts known to the local pcsd which are used to
       login to remote instances of pcsd. Stored information include host addresses,  pcsd  ports
       and authentication tokens.

   pcs_settings.conf
       This JSON file contains web UI and cluster configuration such as clusters managed from web
       UI and cluster permissions.

   pcs_users.conf
       This JSON file stores authentication tokens accepted by local instance of pcsd.

   pcsd.cookiesecret
       Web UI cookie secret.

   pcsd.crt, pcsd.key
       These files contain pcsd server certificate and private key.
