+repmgr: Quickstart guide
+========================
+
+`repmgr` is an open-source tool suite for mananaging replication and failover
+among multiple PostgreSQL server nodes. It enhances PostgreSQL's built-in
+hot-standby capabilities with a set of administration tools for monitoring
+replication, setting up standby servers and performing failover/switchover
+operations.
+
+This quickstart guide assumes you are familiar with PostgreSQL replication
+setup and Linux/UNIX system administration. For a more detailed tutorial
+covering setup on a variety of different systems, see the README.rst file.
+
+Conceptual Overview
+-------------------
+
+`repmgr` provides two binaries:
+
+ - `repmgr`: a command-line client to manage replication and `repmgr` configuration
+ - `repmgrd`: an optional daemon process which runs on standby nodes to monitor
+   replication and node status
+
+Each PostgreSQL node requires a `repmgr.conf` configuration file; additionally
+it must be "registered" using the `repmgr` command-line client. `repmgr` stores
+information about managed nodes in a custom schema on the node's current master
+database.
+
+
+Requirements
+------------
+
+`repmgr` works with PostgreSQL 9.0 and later. All server nodes must be running the
+same PostgreSQL major version, and preferably should be running the same minor
+version.
+
+`repmgr` will work on any Linux or UNIX-like environment capable of running
+PostgreSQL. `rsync` must also be installed.
+
+
+Installation
+------------
+
+`repmgr` must be installed on each PostgreSQL server node.
+
+* Packages
+ - RPM packages for RedHat-based distributions are available from PGDG
+ - Debian/Ubuntu provide .deb packages.
+
+  It is also possible to build .deb packages directly from the `repmgr` source;
+  see README.rst for further details.
+
+* Source installation
+ - `repmgr` source code is hosted at github (https://github.com/2ndQuadrant/repmgr);
+   tar.gz files can be downloaded from https://github.com/2ndQuadrant/repmgr/releases .
+
+   `repmgr` can be built easily using PGXS:
+
+       sudo make USE_PGXS=1 install
+
+
+Configuration
+-------------
+
+### Server configuration
+
+Password-less SSH logins must be enabled for the database system user (typically `postgres`)
+between all server nodes to enable `repmgr` to copy required files.
+
+### PostgreSQL configuration
+
+The master PostgreSQL node needs to be configured for replication with the
+following settings:
+
+    wal_level = 'hot_standby'      # minimal, archive, hot_standby, or logical
+    archive_mode = on              # allows archiving to be done
+    archive_command = 'cd .'       # command to use to archive a logfile segment
+    max_wal_senders = 10           # max number of walsender processes
+    wal_keep_segments = 5000       # in logfile segments, 16MB each; 0 disables
+    hot_standby = on               # "on" allows queries during recovery
+
+Note that `repmgr` expects a default of 5000 wal_keep_segments, although this
+value can be overridden when executing the `repmgr` client.
+
+Additionally, `repmgr` requires a dedicated PostgreSQL superuser account
+and a database in which to store monitoring and replication data. The `repmgr`
+user account will also be used for replication connections from the standby,
+so a seperate replication user with the `REPLICATION` privilege is not required.
+The database can in principle be any database, including the default `postgres`
+one, however it's probably advisable to create a dedicated database for `repmgr`
+usage.
+
+
+### repmgr configuration
+
+Each PostgreSQL node requires a `repmgr.conf` configuration file containing
+identification and database connection information:
+
+    cluster=test
+    node=1
+    node_name=node1
+    conninfo='host=repmgr_node1 user=repmgr_usr dbname=repmgr_db'
+    pg_bindir=/path/to/postgres/bin
+
+* `cluster`: common name for the replication cluster; this must be the same on all nodes
+* `node`: a unique, abitrary integer identifier
+* `name`: a unique, human-readable name
+* `conninfo`: a standard conninfo string enabling repmgr to connect to the
+   control database; user and name must be the same on all nodes, while other
+   parameters such as port may differ. The `host` parameter *must* be a hostname
+   resolvable by all nodes on the cluster.
+* `pg_bindir`: (optional) location of PostgreSQL binaries, if not in the default $PATH
+
+Note that the configuration file should *not* be stored inside the PostgreSQL
+data directory. The configuration file can be specified with the
+`-f, --config-file=PATH` option and can have any arbitrary name. If no
+configuration file is specified, `repmgr` will search for `repmgr.conf`
+in the current working directory.
+
+Each node configuration needs to be registered with `repmgr`, either using the
+`repmgr` command line tool, or the `repmgrd` daemon; for details see below. Details
+about each node are inserted into the `repmgr` database (for details see below).
+
+
+Replication setup and monitoring
+--------------------------------
+
+For the purposes of this guide, we'll assume the database user will be
+`repmgr_usr` and the database will be `repmgr_db`, and that the following
+environment variables are set on each node:
+
+ - $HOME: the PostgreSQL system user's home directory
+ - $PGDATA: the PostgreSQL data directory
+
+
+Master setup
+------------
+
+1. Configure PostgreSQL
+
+  - create user and database:
+
+	```
+	CREATE ROLE repmgr_usr LOGIN SUPERUSER;
+	CREATE DATABASE repmgr_db OWNER repmgr_usr;
+	```
+
+  - configure `postgresql.conf` for replication (see above)
+
+  - update `pg_hba.conf`, e.g.:
+
+	```
+	host    repmgr_db       repmgr_usr  192.168.1.0/24         trust
+	host    replication     repmgr_usr  192.168.1.0/24         trust
+	```
+
+  Restart the PostgreSQL server after making these changes.
+2. Create the `repmgr` configuration file:
+
+        $ cat $HOME/repmgr/repmgr.conf
+        cluster=test
+        node=1
+        node_name=node1
+        conninfo='host=repmgr_node1 user=repmgr_usr dbname=repmgr_db'
+        pg_bindir=/path/to/postgres/bin
+
+   (For an annotated `repmgr.conf` file, see `repmgr.conf.sample` in the
+   repository's root directory).
+
+3. Register the master node with `repmgr`:
+
+        $ repmgr -f $HOME/repmgr/repmgr.conf --verbose master register
+        [2014-07-04 10:43:42] [INFO] repmgr mgr connecting to master database
+        [2014-07-04 10:43:42] [INFO] repmgr connected to master, checking its state

+
+
+Slave/standby setup
+-------------------
+
+1. Use `repmgr` to clone the master:
+
+        $ repmgr -D $PGDATA -d repmgr_db -U repmgr_usr -R postgres --verbose standby clone 192.168.1.2
+        Opening configuration file: ./repmgr.conf

+  -R is the database system user on the master node. At this point it does not matter
+  if the `repmgr.conf` file is not found.
+
+  This will clone the PostgreSQL database files from the master, including its
+  `postgresql.conf` and `pg_hba.conf` files, and additionally automatically create
+  the `recovery.conf` file containing the correct parameters to start streaming
+  from the primary node.
+
+2. Start the PostgreSQL server
+
+3. Create the `repmgr` configuration file:
+
+        $ cat $HOME/repmgr/repmgr.conf
+        cluster=test
+        node=2
+        node_name=node2
+        conninfo='host=repmgr_node2 user=repmgr_usr dbname=repmgr_db'
+        pg_bindir=/path/to/postgres/bin
+
+4. Register the master node with `repmgr`:
+
+        $ repmgr -f $HOME/repmgr/repmgr.conf --verbose standby register
+        Opening configuration file: /path/to/repmgr/repmgr.conf

+
+Monitoring
+----------
+
+`repmgrd` is a management and monitoring daemon which runs on standby nodes
+and which and can automate remote actions. It can be started simply with e.g.:
+
+    repmgrd -f $HOME/repmgr/repmgr.conf --verbose > $HOME/repmgr/repmgr.log 2>&1
+
+or alternatively:
+
+    repmgrd -f $HOME/repmgr/repmgr.conf --verbose --monitoring-history > $HOME/repmgr/repmgrd.log 2>&1
+
+which will track advance or lag of the replication in every standby in the
+`repl_monitor` table.
+
+Example log output:
+
+    [2014-07-04 11:55:17] [INFO] repmgrd Connecting to database 'host=localhost user=repmgr_usr dbname=repmgr_db'

+    [2014-07-04 11:55:17] [INFO] repmgrd Starting continuous standby node monitoring
+
+
+Failover
+--------
+
+To promote a standby to master, on the standby execute e.g.:
+
+    repmgr -f  $HOME/repmgr/repmgr.conf --verbose standby promote
+
+`repmgr` will attempt to connect to the current master to verify that it
+is not available (if it is, `repmgr` will not promote the standby).
+
+Other standby servers need to be told to follow the new master with:
+
+    repmgr -f  $HOME/repmgr/repmgr.conf --verbose standby follow
+
+See file `autofailover_quick_setup.rst` for details on setting up
+automated failover.
+
+
+repmgr database schema
+----------------------
+
+`repmgr` creates a small schema for its own use in the database specified in
+each node's conninfo configuration parameter. This database can in principle
+be any database. The schema name is the global `cluster` name prefixed
+with `repmgr_`, so for the example setup above the schema name is
+`repmgr_test`.
+
+The schema contains two tables:
+
+* `repl_nodes`
+  stores information about all registered servers in the cluster
+* `repl_monitor`
+  stores monitoring information about each node
+
+and one view, `repl_status`, which summarizes the latest monitoring information
+for each node.
