How to install php mbstring extension?

[lkanter]

Hello,
we have php-mbstring rpm, but if you installed cpanel it adds php* to exclude= line in your /etc/yum.conf. Please use cpanel to configure your php.

On CentOS its as simple as running the command "yum install php-mbstring" however when I run it on Cloud Linux I get

root@cpanel [~]# yum install php-mbstring

Loaded plugins: fastestmirror, rhnplugin

Loading mirror speeds from cached hostfile
