Install Redis on Centos 6

1) Install

// --- Compiling ---
$ wget http://download.redis.io/releases/redis-2.8.3.tar.gz
$ tar xzvf redis-2.8.3.tar.gz
$ cd redis-2.8.3
$ make
$ make install

// --- or using yum ---
$ rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
$ rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

$ yum --enablerepo=remi,remi-test install redis

2) Config

$ sudo nano /etc/sysctl.conf
  vm.overcommit_memory=1
$ sysctl vm.overcommit_memory=1

$ sysctl -w fs.file-max=100000

3) Service commands

$ chkconfig --add redis
$ chkconfig --level 345 redis on
$ service redis start/stop/restart

4) Install PHP redis extension

// Install php-redis extension
$ yum --enablerepo=remi,remi-test install php-redis

// If it does not work, try the following steps:
$ wget https://github.com/nicolasff/phpredis/zipball/master -O phpredis.zip
$ unzip phpredis.zip
$ cd nicolasff-phpredis-*
$ phpize
$ ./configure
$ make
$ make install
	Installing shared extensions:     /usr/lib64/php/modules/

What is missing by the Install of the PHP redis extension, is that you should add "extension=redis.so" to your php.ini file.

I donnow how , but , it worked like magic using yu; , (the make. make install didn't work)

// , Unless you want to update all of your packages to the Remi versions the next time you do a $ sudo yum update, I recommend disabling the `/etc/yum.repos.d/remi.repo``.

sudo sed -i -e s%enabled=1%enabled=0%g /etc/yum.repos.d/remi.repo

// , Also, would anyone like some recommendations on setting up Redis Clusters on CEntOS 6 machines?

I am trying this on Centos 6.7 .
redis-server starts, but my install seems to have missed something.

# chkconfig --add redis
error reading information on service redis: No such file or directory

What is chkconfig not finding?

@ChrisGuest I met the same problem. Reinstall using rpm solved it.

If building from source, the init.d scripts are not installed by default. To install them:

[root@centos utils]# cd utils
[root@centos utils]# ./install_server.sh 
Welcome to the redis service installer
This script will help you easily set up a running redis server

Please select the redis port for this instance: [6379] 
Selecting default: 6379
Please select the redis config file name [/etc/redis/6379.conf] 
Selected default - /etc/redis/6379.conf
Please select the redis log file name [/var/log/redis_6379.log] 
Selected default - /var/log/redis_6379.log
Please select the data directory for this instance [/var/lib/redis/6379] 
Selected default - /var/lib/redis/6379
Please select the redis executable path [] /usr/local/bin/redis-server
Selected config:
Port           : 6379
Config file    : /etc/redis/6379.conf
Log file       : /var/log/redis_6379.log
Data dir       : /var/lib/redis/6379
Executable     : /usr/local/bin/redis-server
Cli Executable : /usr/local/bin/redis-cli
Is this ok? Then press ENTER to go on or Ctrl-C to abort.
Copied /tmp/6379.conf => /etc/init.d/redis_6379

The command yum --enablerepo=remi,remi-test install php-redis doesn't work for PHP 5.5.
This works:

yum -y install php55w-pecl-redis

An info for everyone using these guidelines to install Redis. The IUS repository has more uptodate redis packages. I would recommend using these when installing Redis on CentOS 6. The package redis32u installs the server, an init script and a standard config at /etc/redis.conf. The only thing you need to do after installing the package is activate the service with: chkconfig redis on

$ sudo pecl install redis
pecl/redis requires PHP (version >= 7.0.0, version <= 7.1.0, excluded versions: 6.0.0), installed version is 5.6.27
No valid packages found
install failed

Your phpRedis installation doesn't work with php 5.6

This work.
Install Redis 2.2.8 for PHP 5.6

Using Centos 7.0 and EasyApache 4, you can’t install Redis 2.2.8 for PHP 5.6
Easiest workaround is to use shell and following command:
pecl install channel://pecl.php.net/redis-2.2.8

Once it finishes installation, you should see the following lines:
Build process completed successfully
Installing '/opt/cpanel/ea-php56/root/usr/lib64/php/modules/redis.so'
install ok: channel://pecl.php.net/redis-2.2.8
configuration option "php_ini" is not set to php.ini location
You should add "extension=redis.so" to php.ini

Command for test phpredis is work

php -r "if (new Redis() == true){ echo \"OK \r\n\"; }"

=============================
Thank your for your document.

thanks I have been able to install but How can I upgrade version redis?

I couldn't complete setup.

when i run this command:
$ chkconfig --add redis

I get this error:
error reading information on service redis: No such file or directory

Oh man. 46 forks. Which one to choose? Of the forks. 15 modified. 1 with 9 stars and 19 updates, with a tutorial for CentOS 7 linked by a user who was active on GitHub in the last day. Followed those instructions, which had a number of manual steps automated with comment from @vortexau on using the install utility script shipped with the release I built (redis-3.0.4).
