建立新的目录，并创建文件

[root@localhost lnmp]# tree
.
├── conf
│   └── default.conf
├── docker-compose.yml
└── html
    ├── dbtest.php
    ├── index.html
    └── test.php

nginx配置文件：

[root@localhost lnmp]# cat conf/default.conf 
server {
    listen       80;
    listen  [::]:80;
    server_name  localhost;

#charset koi8-r;

    index  index.html index.php index.htm;
}

#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   /usr/share/nginx/html;
}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80

    fastcgi_pass   php:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  /var/www/html/$fastcgi_script_name;
    include        fastcgi_params;
}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one

[root@localhost lnmp]# cat html/dbtest.php 
<?php
$conn=mysql_connect("mysql","root","123456");
if ($conn) echo "it's ok!!!!!";
mysql_close();
?>

测试连接数据库文件：

[root@localhost lnmp]# cat html/dbtest.php 
<?php
$conn=mysql_connect("mysql","root","123456");     ##数据库用户密码
if ($conn) echo "it's ok!!!!!";
mysql_close();
?>

docker-compose.yml 文件：

[root@localhost lnmp]# cat docker-compose.yml 
version: "3"
services:
  nginx:
    image: nginx
    ports:
      - 80
    volumes:
      - /root/lnmp/conf/default.conf:/etc/nginx/conf.d/default.conf    ##配置文件位置映射
