如何在CentOS 7上安装指定版本的PHP

缺省方式下在CentOS 7上安装PHP，版本为5.4，而比如希望使用指定版本，比如7.3，则需要通过yum-config-manager

安装epel和remi

使用如下命令安装epel和remi仓库

执行命令：yum install epel-release remi-release -y

安装yum-utils 确认方法

使用如下命令可以确认yum-config-manager命令在哪个包中：

执行命令：yum whatprovides yum-config-manager

确认之后会发现在yum-utils中，所以接下来需要安装此包

安装yum-utils

使用如下命令可以确认yum-config-manager命令在哪个包中：

执行命令：yum install yum-utils -y

设定安装版本

通过yum-config-manager设定安装的php版本
