Redis Install and Configure

In this tutorial, How to Install and configure Redis on Linux. Now, let’s go Redis Install and Configure.


  • It is an Open Source.
  • In-memory data structure store.
  • Used as Database.
  • Cache and message broker.
  • Redis is a key-value pair cache and store

Redis is perfect for storing sessions. All operations are performed in memory, and so reading and write will be fast

Redis Install and Configure

Download Redis

Link latest Redis home here

$ cd /opt
$ wget
$ sudo tar zxvf redis-5.0.5.tar.gz
$ cd redis-5.0.5

Install Redis

$ sudo make test
$ sudo make
$ sudo make install

If the following error is in make test command as below.

You need tcl 8.5 or newer in order to run the Redis test
make[1]: *** [test] Error 1
make[1]: Leaving directory `/opt/redis-5.0.5/src'
make: *** [test] Error 2

You need to install tcl

$ sudo yum install -y tcl

Again install Redis

$ sudo make test


Executing test client: couldn’t execute “src/redis-benchmark”: no such file or directory.

Then perform the following steps

$ sudo make distclean
$ sudo make
$ sudo make install

Configure Redis

$ sudo mkdir /etc/redis
$ sudo cp redis.conf /etc/redis/6379.conf
$ sudo vi /etc/redis/6379.conf

Create Deamon for Redis

$ sudo cp utils/redis_init_script /etc/init.d/redis
$ sudo chkconfig --add redis
$ sudo chkconfig redis on
$ sudo /etc/init.d/redis start

Redis server has been installed on your system.

$ sudo netstat -nplt | grep 6379                                            
 tcp        0      0    *                   LISTEN      11567/redis-server

For more advanced details the “redis.conf” file configuration item is described as follows:

When the client is idle for a long time, close the connection

timeout 300

Specify the logging level. Redis supports four levels: debug, verbose, notice, warning. The default is verbose.

loglevel verbose

Set the number of databases, the default database is 0, you can use the “select DBID from v$database;” command to specify the database id on the connection

databases 16

Set the IP address and port of the master service when the machine is slav service. When Redis starts, it will automatically synchronize data from the master.

slaveof <masterip> <masterport>

When the master service is password protected, the slav service connects to the master password.

masterauth <master-password>

Set the Redis connection password. If the connection password is configured, the client needs to provide the password through the AUTH command when connecting to Redis. The default is off.

requirepass abc

Set the maximum number of client connections at the same time. The default is unlimited.

maxclients 128

Specify the maximum memory limit of Redis. Redis will load the data into the memory at startup. After the maximum memory is reached, Redis will first try to clear the expired or expired Key. When this method is processed, the maximum memory setting is still reached. The write operation will no longer be possible, but the read operation will still be possible. Redis’ new VM mechanism will store the Key in memory and the value will be stored in the swap area.

maxmemory <bytes>

You can use the same configuration file between multiple Redis instances on the same host, and each instance has its own specific configuration file.

include /path/to/local.conf
