It seems you have php 5.6 installed.
You need to install mbstringfor that particular version of php.
您似乎安装了 php 5.6。
您需要mbstring为该特定版本安装php.
Run sudo yum install php56-mbstring
跑 sudo yum install php56-mbstring
After that it might be a good idea to restart apache (thanks! @hexicle),
using sudo service httpd restart
之后，重新启动 apache 可能是个好主意（谢谢！@hexicle），
使用sudo service httpd restart
