기본적으로 php 7.2 버전 이상부터는 mcypt 를 지원하지 않는다
편법으로 mcrypt를 설치해본자
기존에 웹서버(apache 2.4 ) / php 7.3 버전은 설치되어 있다

현재 php에 mcrypt가 설치되어 있는지 확인해보면 아무런 정보가 표시되지 않는다 즉 미설치 상태

1. libmcrypt 다운로드 및 설치 ( 만약 설치되어 있다면 패스)
   
   Shell

   [root@xinet ~]# wget https://download-ib01.fedoraproject.org/pub/epel/7/x86_64/Packages/l/libmcrypt-2.5.8-13.el7.x86_64.rpm [root@xinet ~]# wget https://download-ib01.fedoraproject.org/pub/epel/7/x86_64/Packages/l/libmcrypt-devel-2.5.8-13.el7.x86_64.rpm [root@xinet ~]# rpm -Uvh libmcrypt-*

   1 2 3 4 5

   [root@xinet ~]# wget https://download-ib01.fedoraproject.org/pub/epel/7/x86_64/Packages/l/libmcrypt-2.5.8-13.el7.x86_64.rpm   [root@xinet ~]# wget https://download-ib01.fedoraproject.org/pub/epel/7/x86_64/Packages/l/libmcrypt-devel-2.5.8-13.el7.x86_64.rpm   [root@xinet ~]# rpm -Uvh libmcrypt-*

   
   2. mcyrpt 1.0 파일 다운로드 및 phpize 이용 설치
   
   Shell

   [root@localhost ~]# wget https://pecl.php.net/get/mcrypt-1.0.2.tgz [root@localhost ~]# tar xvfz mcrypt-1.0.2.tgz [root@localhost ~]# cd mcrypt-1.0.2 [root@localhost mcrypt-1.0.2]# /usr/local/php/bin/phpize Configuring for: PHP Api Version: 20190902 Zend Module Api No: 20190902 Zend Extension Api No: 320190902 [root@localhost mcrypt-1.0.2]# ./configure --with-php-config=/usr/local/php/bin/php-config [root@localhost mcrypt-1.0.2]# make [root@localhost mcrypt-1.0.2]# make install Installing shared extensions: /usr/local/php/lib/php/extensions/debug-zts-20190902/

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

   [root@localhost ~]# wget https://pecl.php.net/get/mcrypt-1.0.2.tgz   [root@localhost ~]# tar xvfz mcrypt-1.0.2.tgz   [root@localhost ~]# cd mcrypt-1.0.2   [root@localhost mcrypt-1.0.2]# /usr/local/php/bin/phpize Configuring for: PHP Api Version:         20190902 Zend Module Api No:      20190902 Zend Extension Api No:   320190902   [root@localhost mcrypt-1.0.2]# ./configure --with-php-config=/usr/local/php/bin/php-config   [root@localhost mcrypt-1.0.2]# make   [root@localhost mcrypt-1.0.2]# make install Installing shared extensions:     /usr/local/php/lib/php/extensions/debug-zts-20190902/

   
    

   3. 파일을 확인하고  파일을 php.ini에서 인식
   

   Shell

   [root@localhost mcrypt-1.0.2]# ls -l /usr/local/php/lib/php/extensions/debug-zts-20190902/ 합계 1732 -rwxr-xr-x 1 root root 105840 8월 10 15:48 mcrypt.so -rwxr-xr-x 1 root root 1665344 7월 27 17:54 opcache.so [root@localhost mcrypt-1.0.2]# vi /usr/local/apache/conf/php.ini extension=mcrypt.so

   1 2 3 4 5 6 7 8

   [root@localhost mcrypt-1.0.2]# ls -l /usr/local/php/lib/php/extensions/debug-zts-20190902/ 합계 1732 -rwxr-xr-x 1 root root  105840  8월 10 15:48 mcrypt.so -rwxr-xr-x 1 root root 1665344  7월 27 17:54 opcache.so   [root@localhost mcrypt-1.0.2]# vi /usr/local/apache/conf/php.ini   extension=mcrypt.so

   
   4. 웹서버 재시작
   
   Shell

   [root@localhost mcrypt-1.0.2]# systemctl restart httpd

   1	[root@localhost mcrypt-1.0.2]# systemctl restart httpd
