docker-compose部署php项目实例详解

1.制定特定扩展的PHP镜像

sudo mkdir -p /www/docker

sudo cd /www/docker

sudo vi Dockerfile

FROM php:7.2-fpm-alpine

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);
