如何解决PHP配置文件中 save_handler 修改不生效

1.修改/etc/php-fpm.conf，或者，/etc/php-fpm.d/*.conf，或者，/usr/local/php/etc/php-fpm.conf

; Set session path to a directory owned by process user  
;php_value[session.save_handler] = files  
;php_value[session.save_path] = /var/lib/php/session     
php_value[session.save_handler] = redis  
php_value[session.save_path] = "tcp://127.0.0.1:6379"

如果php-fpm.conf设置了save_handler，那么php.ini的配置就不会起作用。

2.php-fpm成为内置进程
