2020系统综合实践第3次实践作业

（1）完成Docker-compose的安装

下载Docker-compose

curl -L https://get.daocloud.io/docker/compose/releases/download/1.22.0/docker-compose-uname -s-uname -m > /usr/local/bin/docker-compose

添加权限

sudo chmod +x /usr/local/bin/docker-compose

（2）Dockerfile编写

获取PHP基础镜像

(html,mysql参照上一次作业编写dockerfile）

nginx

FROM nginx:latest
MAINTAINER wang
#default.conf
server {
        listen       80;
        server_name  localhost;
    
        location / {
            root   /var/www/html;
            index  index.html index.htm index.php; # 增加index.php
        }
    
        #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   /var/www/html;
        }
        location ~ .php$ {
            root           /var/www/html; # 代码目录
            fastcgi_pass   phpfpm:9000;    # 修改为phpfpm容器
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name; # 修改为$document_root
            include        fastcgi_params;
        }
    }

phpfpm

FROM php:5.6-fpm
RUN apt-get update && apt-get install -y 
libfreetype6-dev 
libjpeg62-turbo-dev 
libpng12*-dev 
vim 
&& docker-php-ext-install pdo_mysql 
&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ 
&& docker-php-ext-install gd

（3）使用Compose实现多容器运行机制

docker-compose.yml

version: "3"
services:
 nginx:
   build: ./nginx
   ports:
     - "80:80"
   links:
     - "phpfpm"
   volumes:
     - ./html/:/var/www/html/
     - ./nginx/conf/default.conf:/etc/nginx/conf.d/default.conf
 phpfpm:
   build: ./phpfpm
   ports:
     - "9000:9000"
   volumes:
     - ./html/:/var/www/html/
   links:
     - "mysql"
 mysql:
   build: ./mysql
   ports:
     - "3306:3306"
   volumes:
     - ./mysql/data/:/var/lib/mysql/
   environment:
     MYSQL_ROOT_PASSWORD : 123456
