php报错Error: You have to install PHP mcrypt extension!

登录php网页时报错，如下

Error: You have to install PHP mcrypt extension!

环境 php是以模块的方式安装到httpd中

[root@use01 ~]# hostnamectl Static hostname: use01 Icon name: computer-vm Chassis: vm Machine ID: 01f864f07ad64060ab7ceef6f47e3a40 Boot ID: f57ff425ed86492ba1b2a9ad7ba330da Virtualization: vmware Operating System: CentOS Linux 7 (Core) CPE OS Name: cpe:/o:centos:centos:7 Kernel: Linux 3.10.0-957.el7.x86_64 Architecture: x86-64 [root@use01 ~]# apachectl -v Server version: Apache/2.4.6 (CentOS) Server built: Apr 2 2020 13:13:23 [root@use01 ~]# rpm -q php php-5.4.16-48.el7.x86_64

处理 开启mcrypt extension，如没有安装可安装 yum install php-mcrypt

/etc/php.ini ;;;;;;;;;;;;;;;;;;;;;; ; Dynamic Extensions ; ;;;;;;;;;;;;;;;;;;;;;; extension=php_mcrypt.so

重启httpd

[root@use01 ~]# systemctl restart httpd
