Installs Redis on Linux.
On RedHat-based distributions, requires the EPEL repository (you can simply add the role geerlingguy.repo-epel to install ensure EPEL is available).
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.
redis_maxmemory_samples: 5
Number of samples to use to approximate LRU. See Using Redis as an 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
None.
