准备工作

配置yum源"阿里云官方镜像网站"

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo   
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
sed -i 's|$releasever|8|' /etc/yum.repos.d/CentOS-Base.repo  
yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm
sed -i 's|^#baseurl=https://download.fedoraproject.org/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel*
sed -i 's|^metalink|#metalink|' /etc/yum.repos.d/epel*
sed -i 's|$releasever|8|' /etc/yum.repos.d/epel* 

关闭防火墙和selinux

systemctl disable --now firewalld
setenforce 0
sed -ri 's/^(SELINUX=).*/1disabled/g' /etc/selinux/config

安装php

//安装开发工具包
[root@php ~]# yum -y groups mark install 'Development Tools'

//安装依赖包
[root@php ~]# yum -y install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libicu-devel libjpeg libjpeg-devel libpng libpng-devel openldap-devel  pcre-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel mhash mhash-devel php-mysqlnd

//安装php
[root@php ~]# yum -y install php-*

//启动php
[root@php ~]# systemctl start php-fpm

配置apache和php主机

//http主机
#取消注释，启动需要的模块
sed -i '/proxy_module/s/#//g' /etc/httpd24/httpd.conf
sed -i '/proxy_fcgi_module/s/#//g' /etc/httpd24/httpd.conf

#配置虚拟主机
[root@httpd ~]# vim /etc/httpd24/httpd.conf
#在文件的最后一行加上
<VirtualHost *:80>
    DocumentRoot "/usr/local/apache/htdocs/"
    ServerName leidazhuang.com    //域名可以自己设置
    ProxyRequests Off    ProxyPassMatch ^/(.*.php)$ fcgi://192.168.110.13:9000/var/www/html/$1      //这里配置的php主机的IP地址
    <Directory "/usr/local/apache/htdocs/">
        Options none
        AllowOverride none
        Require all granted
    </Directory>
</VirtualHost>

#添加这一行
<IfModule dir_module>
    DirectoryIndex index.php index.html   //在index.html前面加上index.php优先访问前者
</IfModule>

//搜索AddType，添加以下内容
# If the AddEncoding directives above are commented-out, then you
    # probably should define those extensions to indicate media types:
    #
    AddType application/x-compress .Z
    AddType application/x-gzip .gz .tgz
    AddType application/x-httpd-php .php          //添加此行
    AddType application/x-httpd-php-source .phps  //添加此行

//php主机
#修改/etc/php-fpm.d/www.conf
[root@php ~]# vim /etc/php-fpm.d/www.conf

#搜索listen =进行修改
listen = 0.0.0.0:9000								//修改成0.0.0.0：9000
#搜索allowed_进行修改
listen.allowed_clients = 192.168.110.11   //修改成httpd主机的IP地址

#创建php测试页面
[root@php ~]# vim /var/www/html/index.php
<?php
        phpinfo();
?>
[root@php ~]# chown -R apache.apache /var/www/html/

重启服务测试

//重启http和php服务
[root@httpd ~]# apachectl restart
[root@php ~]# systemctl restart php-fpm
