Question

我有两个容器，分别是“ mysql-1 ”和“ ubuntu-1 ”。

我互相联系用过

docker run -p 127.0.0.1:3010:80 -itd --link mysql-1 --name=ubuntu-1 my-ubuntu-image:latest

注意 my-ubuntu-image 已经具有 nginx 和 php ，并且我在其中更改了 config ubuntu-1 如下：

默认

server {
        listen 80 default_server;
        listen [::]:80 default_server;

        root /var/www/html/test/;
        index index.php index.html index.htm index.nginx-debian.html;
        server_name _;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ /index.php$is_args$args;
        }

        location ~ \.php$ {
                try_files $uri /index.php =404;
                fastcgi_pass 127.0.0.1:9999;
                fastcgi_index index.php;
                fastcgi_buffers 16 16k;
                fastcgi_buffer_size 32k;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                #fixes timeouts
                fastcgi_read_timeout 600;
                include fastcgi_params;
        }
}

www.conf

listen = 127.0.0.1:9999

当我尝试运行不带mysql的简单php文件时，它起作用。但是现在我尝试运行如下所示的php文件：

<?php
    $servername = "localhost";
    $username = "root";
    $password = "123456";

    // Create connection
    $conn = new mysqli($servername, $username, $password);

    // Check connection
    if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    } 
    echo "Connected successfully";
?>

如何连接到mysql-1容器？

ubuntu-1内部的环境变量如下：

MYSQL_1_PORT_33060_TCP=tcp://172.17.0.4:33060
MYSQL_1_PORT_33060_TCP_PORT=33060
