1.安装nginx

sudo apt-get install nginx

2.安装php 和php-fpm

sudo apt-get install phpsudo apt-get install php-fpm

3.配置ngixn

进入/etc/nginxg/sites-enabled

vim default //notice 这里只能有一个default的文件 放两个nginx会把报错

完整配置如下

##
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# https://www.nginx.com/resources/wiki/start/
# https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/
# https://wiki.debian.org/Nginx/DirectoryStructure
#
# In most cases, administrators will remove this file from sites-enabled/ and
# leave it as reference inside of sites-available where it will continue to be
# updated by the nginx packaging team.
#
# This file will automatically load configuration files provided by other
# applications, such as Drupal or Wordpress. These applications will be made
# available underneath a path with that package name, such as /drupal8.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

# You can move that to a different file under sites-available/ and symlink that
# to sites-enabled/ to enable it.
#
#server {
#	listen 80;
#	listen [::]:80;
#
#	server_name example.com;
#
#	root /var/www/example.com;
#	index index.html;
#
#	location / {
#		try_files $uri $uri/ =404;
#	}
#}

4.创建一个php文件写个最简单的 index.php

<?php
phpinfo();

5.将这个index.php拷贝到nginxi的webroot  即/var/www/html  在nginx 的nginx。conf文件下有配置这个路径

6.启动php fpm解释 

sudo systemctl start php8.1-fpm.service //这个后缀根据你安装的版本来

7.打开浏览器输入127.0.0.1/index.php就可以可以看到页面啦 ！
