[英]Getting php error related to MySQL server in docker: SQLSTATE[HY000] [2002] Connection refused
When I try to connect php whith the container that has the mysql server I get this error当我尝试将 php 连接到具有 mysql 服务器的容器时,出现此错误
NOTICE: PHP message: PHP Fatal error: Uncaught PDOException: SQLSTATE[HY000] [2002] Connection refused in /app/public/src/ConexaoBD.php:5

This is the docker compose file:这是 docker 撰写文件:
version: '3.1'
services:
memcached:
image: 'memcached:alpine'
mailhog:
image: 'mailhog/mailhog:latest'
ports:
- '8001:8025'
redis:
image: 'redis:alpine'
mysql:
image: 'mysql:8.0'
working_dir: /app
volumes:
- ./init:/docker-entrypoint-initdb.d
environment:
- MYSQL_ROOT_PASSWORD=1234
- MYSQL_PASSWORD=1234
ports:
- '8002:3306'
clickhouse:
image: 'yandex/clickhouse-server:latest'
webserver:
image: 'nginx:alpine'
working_dir: /app
volumes:
- '.:/app'
- './phpdocker/nginx/nginx.conf:/etc/nginx/conf.d/default.conf'
ports:
- '8000:80'
php-fpm:
build: phpdocker/php-fpm
working_dir: /app
volumes:
- '.:/app'
- './phpdocker/php-fpm/php-ini-overrides.ini:/etc/php/8.2/fpm/conf.d/99-overrides.ini'
This is the connection class:这是连接 class:
class ConexaoBD{
public static function getConexao():PDO{
$conexao = new PDO("mysql:host=127.0.0.1;port=8002;dbname=lisbuy","root","1234",
array(PDO::ATTR_PERSISTENT => true));
return $conexao;
}
}
Now that I changed the host to 127.0.0.1, the connection is refused.现在我将主机更改为 127.0.0.1,连接被拒绝。 And there's no way that the MySQL server isn't running, cause i can connect to it using php-server, but the nginx webserver won't connect而且 MySQL 服务器不可能没有运行,因为我可以使用 php-server 连接到它,但是 nginx 网络服务器无法连接
To resolve this I checked the.network of my project为了解决这个问题,我检查了我项目的.network
docker network ls
Which resulted in this:结果是:
NETWORK ID NAME DRIVER SCOPE网络 ID 名称驱动程序 SCOPE
2d29fdfc097d bridge bridge local 2d29fdfc097d 桥桥本地
daacebb20248 getting-started_default bridge local daacebb20248 getting-started_default 网桥本地
417454d96fb2 host host local 417454d96fb2 主机主机本地
86e9b81f44b9 none null local 86e9b81f44b9 无 null 本地
57081b8817bf projeto-ecommerce_default bridge local 57081b8817bf projeto-ecommerce_default 桥本地
Then I run:然后我跑:
docker network inspect 57081b8817bf
And got this:得到这个:
"98e3771dbbf9070f18da96614e586faeed0274d9933c093c2e45984de005f930": {
"Name": "projeto-ecommerce-mysql-1",
"EndpointID": "f6003fd274f8701e96b6f4e8bfc552eb5f6fdb22c2976980519705f9736c1d0d",
"MacAddress": "02:42:ac:13:00:05",
"IPv4Address": "172.19.0.5/16",
"IPv6Address": ""
Then, in the connection class I just added the "Name" of the container to the host connection variable:然后,在连接 class 中,我将容器的“名称”添加到主机连接变量中:
public static function getConexao():PDO{
$conexao = new PDO("mysql:host=projeto-ecommerce-mysql-1;dbname=lisbuy","root","1234");
return $conexao;
}
And worked!并且工作了!
