在Linux操作系统中，CentOS是一种广泛使用的开源服务器操作系统，它以其稳定性、安全性和灵活性而受到许多开发者和企业的青睐，PHP是一种广泛使用的开源服务器端脚本语言，用于创建动态网页和应用，本文将详细介绍如何在CentOS上安装和配置PHP环境。
1、更新系统软件包
我们需要更新系统软件包，以确保我们使用的是最新的软件包，在终端中输入以下命令：
sudo yum update
2、安装EPEL存储库
EPEL（Extra Packages for Enterprise Linux）是Fedora项目的一部分，它提供了额外的软件包，这些软件包不在默认的CentOS存储库中，我们需要安装EPEL存储库，以便我们可以安装更多的软件包，在终端中输入以下命令：
sudo yum install epel-release
3、安装Apache HTTP服务器
Apache HTTP服务器是一个开源的、跨平台的、模块化的HTTP服务器，它是最流行的Web服务器之一，在终端中输入以下命令来安装Apache：
sudo yum install httpd
4、启动并设置开机启动Apache服务
安装完成后，我们需要启动Apache服务，并将其设置为开机启动，在终端中输入以下命令：
sudo systemctl start httpd sudo systemctl enable httpd
5、安装PHP及其扩展
接下来，我们将安装PHP及其一些常用的扩展，在终端中输入以下命令：
sudo yum install php php-mysql php-fpm php-mbstring php-xml php-pear php-gd php-curl php-zip php-json php-bcmath php-ldap php-intl php-soap curl curl-devel libxml2-devel openssl-devel gd-devel bzip2-devel libcurl-devel libjpeg-devel libpng-devel freetype-devel libmcrypt-devel libxslt-devel zlib1g-devel libicu-devel libidn11-devel libpspell-devel librecode-devel libtidy-devel libonig-devel libxslt-devel libexif-devel gettext gettext-devel ncurses ncurses-devel readline readline-devel sqlite3 sqlite3-devel pcre pcre-devel openssl openssl-devel perl perl-devel wget zip unzip net-tools bind-utils rsync mod_ssl mod_perl mod_python mod_fcgid mod_wsgi python2 python2-devel python3 python3-devel patch autoconf automake bison gcc gcc-c++ make nasm openssl openssl-devel pcre pcre-devel zlib zlib-devel libtool libtool-ltdl xz xz-devel mhash mhash-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libmcrypt mcrypt-devel libm
