执行

ps -ef | grep php-fpm

可以看到多版本 PHP 运行情况

[root@iZbp14vt99zpj8dde2fdlmZ ~]# ps -ef | grep php-fpm
root      818812       1  0 00:16 ?        00:00:00 php-fpm: master process (/usr/local/php/etc/php-fpm.conf)
root      818845       1  0 00:16 ?        00:00:00 php-fpm: master process (/usr/local/php7.4/etc/php-fpm.conf)

修改vhoust

增加以下内容

#include enable-php-pathinfo.conf;
include enable-php7.4.conf;

检查项目是否已经使用7.4PHP

<?php
	phpinfo();
?>

更改环境变量的PHP

cd /usr/bin
sudo rm -rf ./php
cd /usr/bin
sudo ln -s /usr/local/php7.4/bin/php /usr/bin/php

如下

[root@iZbp14vt99zpj8dde2fdlmZ ~]# ll /usr/bin/ | grep php
