CentOS 7：缺少mbstring扩展名

Question

I've installed phpmyadmin (4.5.3.1) on CentOS 07 with apache server (httpd-2.4.18) and PHP 7.0.1. I get the error:

The mbstring extension is missing. Please check your PHP configuration.

So I searched the internet for this error and people came with the following solution, which I tried:

Installing the php-mbstring and php-mcrypt extensions:

yum install php-mbstring php-mcrypt php-gd

this command returns:

Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: mirrors.viethosting.vn
 * epel: ftp.cuhk.edu.hk
 * extras: mirrors.viethosting.vn
 * updates: mirrors.viethosting.vn

Package php-mbstring-5.4.16-36.el7_1.x86_64 already installed and latest version

Package php-mcrypt-5.4.16-3.el7.x86_64 already installed and latest version

Package php-gd-5.4.16-36.el7_1.x86_64 already installed and latest version

Nothing to do

Please help me!

You need to check your php.ini and make sure it is loading the mbstring extension, or load it at runtime:

Here for the ini extension loading:
