在CentOS的7官方软件仓库有PHP 5.4已经走到了生命的完毕，由开发商不再积极保护。

要理解最新功效和平安更新，您需要在CentOS 7系统上使用更新的（大概是最新的）PHP版本。

在CentOS 7上安置PHP 7

安置必要

yum -y install gcc gcc-c++

1.要安置PHP 7，您必需使用以下命令在CentOS 7系统上安置和启用EPEL和Remi储备库。

#yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
#yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

2.接下来，您需要安置yum-utils，这是一组用于治理yum储备库和包的有用程序。它有根本上扩展yum默许功效的工具。

它可用于治理（启用或禁用）yum储备库乃至包，无需任何手动配置等等。

#yum -y install yum-utils

3. yum-utils供给的程序之一是yum-config-manager，您可以使用它来启用Remi储备库作为安置不一样PHP版本的默许储备库，如图所示。

#yum-config-manager --enable remi-php71 [ 安置PHP 7.1 ]
#yum-config-manager --enable remi-php72 [ 安置PHP 7.2 ]
#yum-config-manager --enable remi-php73 [ 安置PHP 7.3 ]

4.此刻使用以下命令安置PHP 7乃至所有必需的模块。

#yum -y install php php-mcrypt php-devel php-cli php-gd php-pear php-curl php-fpm php-mysql php-ldap php-zip php-fileinfo

5.查看php版本

[root@VM_159_140_centos lnmp]# php -v
