This guide will help you for the installation of Redis server and binding with PHP using Redis PHP extensions on a cPanel server.

Step 1 – Prerequisites

In order to use this tutorial, you must have root shell access of your WHM/cPanel server. Login to your server shell access using root account.

ssh root@remote.cpanel

Redis packages are not available under default yum repositories. You need to enable EPEL yum repository on your server first. Execute below command to enable:

### CentOS/RHEL 7 
yum install epel-release

### CentOS/RHEL 6 
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

Step 2 – Install Redis Server

Now, You can use yum package manage to install Redis server packages by executing below command

yum install redis

After successfully installation start Redis service and enable to auto-start on system reboot.

### CentOS/RHEL 7 
systemctl enable redis
systemctl start redis

### CentOS/RHEL 6 
chkconfig redis on
service redis restart

Redis server is up and running on your system. Go to next step to enable Redis PHP extension on your cPanel server.

Step 3 – Install Redis PHP extension

In this step there are two option available based in the EasyApache version on your cPanel server. Follow one of below step:

cPanel with EasyApache 4

You can install Redis PHP extension for all installed PHP version on your system or install for the active version only. We recommend to install for all versions.

PHP 5.6

/opt/cpanel/ea-php56/root/usr/bin/pecl install igbinary igbinary-devel redis 
/opt/cpanel/ea-php56/root/usr/bin/php -m | grep redis

PHP 7.0

/opt/cpanel/ea-php70/root/usr/bin/pecl install igbinary igbinary-devel redis 
/opt/cpanel/ea-php70/root/usr/bin/php -m | grep redis

PHP 7.1

/opt/cpanel/ea-php71/root/usr/bin/pecl install igbinary igbinary-devel redis 
/opt/cpanel/ea-php71/root/usr/bin/php -m | grep redis

cPanel with EasyApache 3

If the cPanel is still running with EasyApache 3, Execute below commands to install Redis PHP extension on your system. Also check Redis module is enabled for PHP.

pecl install igbinary igbinary-devel redis
php -m | grep redis

All done. Redis has been installed on your system along with the PHP extension.

Error: The login is invalid

After that I google about this issue and found few solutions in which below solution work for me.

Solution:

This issue is creating due to my IP address was blocked by cphulkd. So I have added my ip to white list using following command. Make sure to change 11.22.33.44 with your actual public ip. To find your public ip visit here.

But If we want to add our own custom configuration in the Apache configuration of any website VirtualHost, We can do it by creating a configuration file at /usr/local/apache/conf/userdata/std/2_2/<username>/<sitename.com>/extra.conf.

In other versions, this location may change. So to find this location, check the website VirtualHost in the main configuration file, at the end of VirtualHost you will get a location like below

# To customize this VirtualHost use an include file at the following location
# Include "/usr/local/apache/conf/userdata/ssl/2_2/myuser/mydomain.com/*.conf"

Adding Custom Settings in Apache cPanel

Now use the following commands to create a directory structure and configuration file. Change myuser with your actual cPanel username and change mydomain.com with actual domain name for which you want to add custom settings.

mkdir -p /usr/local/apache/conf/userdata/ssl/2_2/myuser/mydomain.com/ 
cd /usr/local/apache/conf/userdata/ssl/2_2/myuser/mydomain.com/ 

Now create configuration file with any name but with .conf extension

vim extra.conf 

Put your custom settings in extra.conf file and execute the following command from the shell. This command will uncomment the “Include “/usr/local/apache/conf/userdata/ssl/2_2/myuser/mydomain.com/*.conf” line in the VirtualHost of the main Apache configuration file.

/scripts/ensure_vhost_includes --all-users 

And all done. In this way, you will not lose any custom changes for your VirtualHost.

This tutorial will help you to install IonCube Loaders in cPanel server without recompiling Apache/PHP on cPanel server. If you are not running cPanel server, read article Install IonCube Loader in CentOS/RHEL (non cPanel Server).

Install IonCube Loaders in cPanel

To install ioncube first connect to your server using root access using ssh client (e.g. Putty ) and execute following command.

# /scripts/phpextensionmgr install IonCubeLoader

This script will install the ionCube loader and do all required settings. below is the sample output of above command

Updating md5sum list
Fetching http://httpupdate.cpanel.net/cpanelsync/easy/targz.yaml (connected:0).......(request attempt 1/12)...Using dns cache file /root/.HttpRequest/httpupdate.cpanel.net......searching for mirrors (mirror search attempt 1/3)......loaded mirror speeds from cache......mirror search success......connecting to 91.121.124.18...@91.121.124.18......connected......receiving...100%......request success......Done
Installing IonCubeLoader
Determining PHP version
Installing IonCube Loader binaries
Activating IonCube Loader extension in /usr/local/lib/php.ini
IonCube Loader extension activated

Verify IonCube Loader

After installing ionCube Loader, You can verify it by the Linux command line using below command

php -v

Sample Output
