在CentOS的7官方软件仓库有PHP 5.4已经走到了生命的结束,由开发商不再积极维护。

要了解最新功能和安全更新,您需要在CentOS 7系统上使用更新的(可能是最新的)PHP版本。

在CentOS 7上安装PHP 7

安装必要

yum -y install gcc gcc-c++

1.要安装PHP 7,您必须使用以下命令在CentOS 7系统上安装和启用EPEL和Remi存储库。

#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,您需要安装yum-utils,这是一组用于管理yum存储库和包的有用程序。它有基本上扩展yum默认功能的工具。

它可用于管理(启用或禁用)yum存储库以及包,无需任何手动配置等等。

#yum -y install yum-utils

3. yum-utils提供的程序之一是yum-config-manager,您可以使用它来启用Remi存储库作为安装不同PHP版本的默认存储库,如图所示。

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

4.现在使用以下命令安装PHP 7以及所有必需的模块。

#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

6.启动php-fpm

systemctl start php-fpm
