EXPOSE 9000

2.编写yml文件

sudo vi docker-compose.yml

version: '3.1'

services:

 nginx:

 image: nginx

 container_name: nginx

 restart: always

 ports:

 - "80:80"

 - "443:443"

 volumes:

 - /www/data/nginx/conf.d:/etc/nginx/conf.d

 - /www/default:/www/default

 networks:

 csl:

 ipv4_address: 172.18.0.2

 

 php:

 image: php:7.2-fpm-alpine-dcwd

 container_name: php7.2

 restart: always

 volumes:

 - /www/default:/www/default

 networks:

 csl:

 ipv4_address: 172.18.0.3 mysql5:

 image: mysql:5.7

 container_name: mysql5

 restart: always

 ports:

 - "3306:3306"

 environment:

 MYSQL_ROOT_PASSWORD: thisyourpassword

 volumes:

 - /www/data/mysql/mysql5:/var/lib/mysql #- /www/data/mysql/mysql5/conf/my.cnf:/etc/my.cnf

 #- /www/data/mysql/mysql5/init:/docker-entrypoint-initdb.d

 networks:

 csl:

 ipv4_address: 172.18.0.4 mysql8:

 image: mysql:8

 container_name: mysql8

 restart: always

 environment:

 MYSQL_ROOT_PASSWORD: thisyourpassword

 volumes:

 - /www/data/mysql/mysql8:/var/lib/mysql networks:

 csl:

 ipv4_address: 172.18.0.5

networks:

 csl:

 driver: bridge

 ipam:

 config:

 - subnet: 172.18.0.0/16

3.配置default.conf文件

sudo vi /www/data/nginx/default.conf

server {

 listen 80;

 server_name localhost;

 #charset koi8-r;

 #access_log /var/log/nginx/host.access.log main;

 location / {

 root /www/default;

 index index.php 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$ {

 root /www/default;

 fastcgi_pass php7.2:9000;#php容器名或者php容器ip

 fastcgi_index index.php;

 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;

 #}

}

4.修改mysql允许远程连接并新建数据库

docker exec -it mysql5 bash

mysql -u root -p

use mysql;

update user set host='%' where user='root';

flush privileges;

5.创建并且启动容器

docker-compose up -d

6.新建index.php测试mysql连接

<?php

$con = mysqli_connect("172.18.0.4", "root", "thisyourpassword", "shop");

if ($con) {

 echo '连接 MYSQL 成功';

} else {

 echo "连接 MySQL 失败: " . mysqli_connect_error();

} mysqli_close($con);
