# Ansible Role: Redis
|
|
|
|
[](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.
