Php 无法打开共享对象文件：amazon-elasticache-cluster-client.so没有此类文件或目录

在执行systemctl restart php fpm时，我不断收到这些php警告

[23-Apr-2019 09:54:12] NOTICE: PHP message: PHP Warning:  PHP Startup: Unable to load dynamic library 'amazon-elasticache-cluster-client.so' (tried: /opt/remi/php72/root/usr/lib64/php/modules/amazon-elasticache-cluster-client.so (/opt/remi/php72/root/usr/lib64/php/modules/amazon-elasticache-cluster-client.so: failed to map segment from shared object: Permission denied), /opt/remi/php72/root/usr/lib64/php/modules/amazon-elasticache-cluster-client.so.so (/opt/remi/php72/root/usr/lib64/php/modules/amazon-elasticache-cluster-client.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

在ec2机器上，memcached和session配置正确

/etc/opt/remi/php72/php.d/session.ini,

session.trans_sid_tags => a=href,area=href,frame=src,form= => a=href,area=href,frame=src,form=

但是从网站上的info.php访问这个，似乎

session.save\u path

和

session.save\u handler

被过度编写了

任何关于如何解决此问题的建议都将不胜感激
