+# Ansible Role: Redis
+
+[![Build Status](https://travis-ci.org/geerlingguy/ansible-role-redis.svg?branch=master)](https://travis-ci.org/geerlingguy/ansible-role-redis)
+
+Installs [Redis](http://redis.io/) on RHEL/CentOS or Debian/Ubuntu.
+
+## Requirements
+
+On RedHat-based distributions, requires the EPEL repository (you can simply add the role `geerlingguy.repo-epel` to install ensure EPEL is available).
+
+## Role Variables
+
+    redis_enablerepo: epel
+
+(Used only on RHEL/CentOS) The repository to use for Redis installation.
+
+Available variables are listed below, along with default values (see `defaults/main.yml`):
+
+    redis_port: 6379
+    redis_bind_interface: 127.0.0.1
+
+Port and interface on which Redis will listen. Set the interface to `0.0.0.0` to listen on all interfaces.
+
+    redis_unixsocket: ''
+
+If set, Redis will also listen on a local Unix socket.
+
+    redis_timeout: 300
+
+Close a connection after a client is idle `N` seconds. Set to `0` to disable timeout.
+
+    redis_loglevel: "notice"
+    redis_logfile: /var/log/redis/redis-server.log
+
+Log level and log location (valid levels are `debug`, `verbose`, `notice`, and `warning`).
+
+    redis_databases: 16
+
+The number of Redis databases.
+
+    # Set to an empty set to disable persistence (saving the DB to disk).
+    redis_save:
+      - 900 1
+      - 300 10
+      - 60 10000
+
+Snapshotting configuration; setting values in this list will save the database to disk if the given number of seconds (e.g. `900`) and the given number of write operations (e.g. `1`) have occurred.
+
+    redis_rdbcompression: "yes"
+    redis_dbfilename: dump.rdb
+    redis_dbdir: /var/lib/redis
+
+Database compression and location configuration.
+
+    redis_maxmemory: 0
+
+Limit memory usage to the specified amount of bytes. Leave at 0 for unlimited.
+
+    redis_maxmemory_policy: "noeviction"
+
+The method to use to keep memory usage below the limit, if specified. See [Using Redis as an LRU cache](http://redis.io/topics/lru-cache).
+
+    redis_maxmemory_samples: 5
+
+Number of samples to use to approximate LRU. See [Using Redis as an LRU cache](http://redis.io/topics/lru-cache).
+
+    redis_appendonly: "no"
+
+The appendonly option, if enabled, affords better data durability guarantees, at the cost of slightly slower performance.
+
+    redis_appendfsync: "everysec"
+
+Valid values are `always` (slower, safest), `everysec` (happy medium), or `no` (let the filesystem flush data when it wants, most risky).
+
+    # Add extra include files for local configuration/overrides.
+    redis_includes: []
+
+Add extra include file paths to this list to include more/localized Redis configuration.
+
+The redis package name for installation via the system package manager. Defaults to `redis-server` on Debian and `redis` on RHEL.
+
+    redis_package_name: "redis-server"
+
+(Default for RHEL shown) The redis package name for installation via the system package manager. Defaults to `redis-server` on Debian and `redis` on RHEL.
+
+    redis_requirepass: ""
+
+Set a password to require authentication to Redis. You can generate a strong password using `echo "my_password_here" | sha256sum`.
+
+    redis_disabled_commands: []
+
+For extra security, you can disable certain Redis commands (this is especially important if Redis is publicly accessible). For example:
+
+    redis_disabled_commands:
+      - FLUSHDB
+      - FLUSHALL
+      - KEYS
+      - PEXPIRE
+      - DEL
+      - CONFIG
+      - SHUTDOWN
+
+## Dependencies
+
+None.
+
+## Example Playbook
+
+    - hosts: all
+      roles:
+        - { role: geerlingguy.redis }
+
+## License
+
+MIT / BSD
+
+## Author Information
+
+This role was created in 2014 by [Jeff Geerling](https://www.jeffgeerling.com/), author of [Ansible for DevOps](https://www.ansiblefordevops.com/).

+# Ansible Role tests
+
+To run the test playbook(s) in this directory:
+
+  1. Install and start Docker.
+  1. Download the test shim (see .travis.yml file for the URL) into `tests/test.sh`:
+    - `wget -O tests/test.sh https://gist.githubusercontent.com/geerlingguy/73ef1e5ee45d8694570f334be385e181/raw/`
+  1. Make the test shim executable: `chmod +x tests/test.sh`.
+  1. Run (from the role root directory) `distro=[distro] playbook=[playbook] ./tests/test.sh`
+
+If you don't want the container to be automatically deleted after the test playbook is run, add the following environment variables: `cleanup=false container_id=$(date +%s)`
