1.制定特定扩展的PHP镜像

?

1	sudo mkdir -p /www/docker

?

1	sudo cd /www/docker

?

1	sudo vi Dockerfile

?

2.编写yml文件

?

1	sudo vi docker-compose.yml

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105

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

?

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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73

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

?

1 2 3 4 5 6 7 8 9

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

?

1	docker-compose up -d

6.新建index.php测试mysql连接

?

1 2 3 4 5 6 7 8 9 10 11 12 13

<?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);
