一、安装nginx

1、加载EPLE软件仓库

sudo yum install epel-release

2、安装nginx

sudo yum install nginx

3、启动nginx

sudo systemctl start nginx

二、安装php 7.2

0、如果安装过php先卸载

sudo yum -y remove php*

1、加载软件源

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm   
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm    

2、安装各种扩展

yum -y install php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-fpm php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml

2.1 如果要支持pecl

yum install php72w-pear

三、配置nginx服务器的php

1、删除原来的配置文件，复制默认配置文件

cd  /usr/share/nginx/
rm -rf nginx.conf
cp nginx.conf.default nginx.conf

2、修改配置文件

vim nginx.conf

server {
         listen       80;
         server_name  localhost;

        #charset koi8-r;

          #access_log  logs/host.access.log  main;

          location / {
              root   html;
              # 修改1：这里新增了index.php
              index index.html index.htm index.php;
              # 修改2：这里新增url重写（path）
              try_files $uri $uri/ /index.php$is_args$args;
          }

          #error_page  404              /404.html;

          # redirect server error pages to the static page /50x.html
          #
          error_page   500 502 503 504  /50x.html;
          location = /50x.html {

             root   html;
          }

          # proxy the PHP scripts to Apache listening on 127.0.0.1:80
          #
          #location ~ \.php$ {
          #    proxy_pass   http://127.0.0.1;
          #}

          # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
          #
    #修改3：解开php支持的注释
          location ~ \.php$ {
              root           html;
              #默认就使用php-fpm
              fastcgi_pass   127.0.0.1:9000;
              fastcgi_index  index.php;
              #修改4：修改fastcig的路径
              fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
              include        fastcgi_params;
          }

          # deny access to .htaccess files, if Apache's document root
          # concurs with nginx's one
          #
          #location ~ /\.ht {
          #    deny  all;
          #}
      }

#保存并关闭

3、重启nginx

systemctl restart nginx

4、编写测试文件测试

cd /usr/share/nginx/html/
vim phptest.php

<?php
phpinfo();

#保存并退出
