Linux-centos7 Installing PHP Extensions

Today, when using PHP in Centos7, the mbstring extension is not installed, so use Yum instll php-mbstring
After installation, it is found that the/etc/php.d/directory has mbstring.iniFile and there's a line inside. extension=mbstring.so
/usr/lib64/php/modules/In the catalogue there are also mbstring.soFile, after restarting Nginx found phpinfoThere is still no mbsting extension, why? Is it a step that I'm missing?
The same directory of Curl and other extensions are such a configuration, why loaded in, and the newly installed mbstring load do not come in?

PS: It has been solved. The reason is that there is no restart php-fpm after installation, it is useless to restart Nginx. Thank you!

PHP.ini plus extension=mbstring.so.

Try setting the extension_dirin php.ini and set it to absolute path.

Some people have done the same thing, but I'm not sure if it's the same as the main problem.

sudo yum remove php-commonsudo yum install php-mbstring
