Redis
Introduction
• Redis is an open source (BSD licensed), in-memory data
structure store, used as a database, cache and message
broker. It supports data structures such as strings, hashes,
lists, sets, sorted sets with range queries, bitmaps,
hyperloglogs, geospatial indexes with radius queries and
streams. Redis has built-in replication, Lua scripting, LRU
eviction, transactions and different levels of on-disk
persistence, and provides high availability via Redis
Sentinel and automatic partitioning with Redis Cluster.

Oracle Linux
Introduction
Johan Louwers
• The Oracle Linux operating system is engineered for open
cloud infrastructure. It delivers leading performance,
scalability, reliability and security for enterprise SaaS and
PaaS workloads as well as traditional enterprise
applications. Oracle Linux Support offers access to award-
winning Oracle support resources and Linux support
specialists, zero-downtime updates using Ksplice,
additional management tools such as Oracle Enterprise
Manager and lifetime support, all at a low cost. Unlike
many other commercial Linux distributions, Oracle Linux is
easy to download and completely free to use, distribute
and update.

Oracle Linux – Network settings
Network settings:
• This guide assumes that you have both a eth0
and a eth1 network interface.
• Having a different set of network interfaces will
not hinder you from using Redis.

Oracle Linux – Set the correct yum repo
Yum settings:
• Ensure you have the EPEL repository configured
in your yum config.
• To install the EPEL repo you can use the following
command:
rpm -ivh
https://dl.fedoraproject.org/pub/epe
l/epel-release-latest-7.noarch.rpm
• Check the enabled repositories with yum
repolist command this now should list:

Start Redis:
• Ensure you start Reduis with the following
command:
systemctl start redis
• Ensure you enable the redis service with the
following command:
systemctl enable redis
• You can check the status with the following
command:
systemctl status redis
Johan Louwers
Start Redis as a Service

[root@localhost ~]# redis-cli ping
PONG
[root@localhost ~]#
Check if Redis is working:
• You can use the redis-cli to do a ping, if the
response is PONG your service is up and running

40 # By default, if no "bind" configuration directive is specified, Redis listens
41 # for connections from all the network interfaces available on the server.
42 # It is possible to listen to just one or multiple selected interfaces using
43 # the "bind" configuration directive, followed by one or more IP addresses.
44 #
45 # Examples:
46 #
47 # bind 192.168.1.100 10.0.0.1
48 # bind 127.0.0.1 ::1
49 #
50 # ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
51 # internet, binding to all the interfaces is dangerous and will expose the
52 # instance to everybody on the internet. So by default we uncomment the
53 # following bind directive, that will force Redis to listen only into
54 # the IPv4 lookback interface address (this means Redis will be able to
55 # accept connections only from clients running into the same computer it
56 # is running).
57 #
58 # IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
59 # JUST COMMENT THE FOLLOWING LINE.
60 # ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
61 bind 127.0.0.1 192.168.33.12 10.0.2.15
62
Optional network config
• By default Redis will only listen to localhost /
127.0.0.1 and will not allow remote connections.
• In case you want to allow remote connections to
Redis you will have make some changes to the
/etc/redis.conf configuration file.
• Find the bind config and add your external IP(s)
to this. In our example case those will be:
192.168.33.12 and 10.0.2.15 (DO NOTE line 61)
• Do restart the bind service after changing the
settings
Johan Louwers

[root@localhost ~]# netstat -antup | grep -i 6379

tcp 0 0 127.0.0.1:6379 127.0.0.1:36795 TIME_WAIT -
[root@localhost ~]#
Verify Redis is listening
• You can verify if Redis is listening now on all NIC
as it should be by invoking a netstat command.
• This should have given you a working Redis
server for your development work.
