I want to install Redis into my server, I have gone through the instruction mention here, but still I am not able to configure redis into my server. Please find below command which help you to understand what I am doing wrong ?


bash-4.1# service redis_6379 restart

/var/run/ does not exist, process is not running
Starting Redis server...

Reading the configuration file, at line 55

'tcp-backlog 511'
Bad directive or wrong number of arguments

bash-4.1# redis-server

[27218] 20 Jun 01:42:13.166 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf
[27218] 20 Jun 01:42:13.167 * Max number of open files set to 10032
[27218] 20 Jun 01:42:13.167 # Creating Server TCP listening socket *:6379: bind: Address already in use

bash-4.1# redis-cli> ping

NOTE : Here after entering "ping", redis goes stuck and doesnt display any output.

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

Copy link

$ 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://

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


Command for test phpredis is work

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


Thank your for your document.

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).
