php -m | grep mbstring

This is here. if you are not there, you will not be there.
If not, download the mbstring source code again, compile and install it.

The above is the answer before the subject changes ..

No extensions are loaded in ini. will php-m contain?
Is php-cli the same version as php-cgi?
It won't be because the local machine has two versions of php ..

Someone has asked this question before. please refer to this question at https://segmentfault.com/q/10 ....
The main reason is that after the extension is installed, the php-fpm (FastCGI Process Manager: FastCGI Process Manager) is not restarted, resulting in inconsistent php configuration files loaded by cgi and cli.
