Linux 服务器中 PHP 版本从 5.x 升级到 7.x

如果把 linux 服务器的 PHP 版本升级呢？比如目前版本是 php 5.6.40，升级到7.4 当前最最新版本 PHP 7.4.30。

查看当前 PHP 版本

 php -v

卸载已安装的 PHP

yum remove php-common

安装 EPEL 源

yum install epel-release

如果已安装过，则提示如下：

安装 remi 源

yum install Http://rpms.remirepo.net/enterprise/remi-release-7.rpm

安装 yum-config-manager

yum install yum-utils

指定 remi 的php 7.4 仓库

yum-config-manager --enable remi-php74

注意：如果要安装其它 PHP 版本，可以把上面命令中的 remi-php74 改为 remi-php72、remi-php71、remi-php70 等。

输出结果：
