1.建立工作目录

mkdir -p /home/test/html && cd /home/test/html

2.准备nginx配置文件  touch nginx.conf

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html 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
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
        fastcgi_pass   php-fpm:9000; #这里是nginx 与 php-fpm 容器所在同一网络的服务名
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /var/www/html$fastcgi_script_name; #php-fpm 容器中php代码位置
        include        fastcgi_params;
    }

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

3.创建容器通信网络

docker network create -d bridge my_network

4.启动php-fpm 容器

docker pull php:7.4-fpm

docker run -itd --network my_network --name php-fpm -v /home/test/html:/var/www/html  php:7.4-fpm

5.创建nginx 的dockerfile 文件并启动   touch nginx_dfile

FROM nginx
COPY nginx.conf /etc/nginx/conf.d/default.conf
#需要替换配置文件

6.启动nginx 因为nginx依赖于php-fpm 所以先启动php-fpm

docker build -f nginx_dfile -t my_nginx .

docker run -d -p 8080:80 --network my_network --name nginx -v /home/test/html:/usr/share/nginx/html my_nginx

7.测试 touch index.php 

<?php
    phpinfo();

8. 浏览器访问8080 端口

笔记docker 常用命令

#停止并删除所有容器
docker stop $(docker ps -aq) && docker rm $(docker ps -aq) 

#查看所有容器
docker ps -a
