尝试将 Jira（docker）连接到 Mysql（非 docker）5.6.44，但连接被拒绝

我正在尝试在 CentOS 7 虚拟机上配置 jira。我设法启动了 Jira 的 docker 镜像，而 docker-compose 没有任何问题：

 jira:
    image: 'cptactionhank/atlassian-jira-software:latest'
    container_name: jira
    restart: unless-stopped
    healthcheck:
      disable: true
    volumes:
      - '/var/atlassian/jira:/var/atlassian/jira'

我还在我的虚拟机上安装了 mySQL（不使用 docker），同时遵循此处描述的安装过程：https : //confluence.atlassian.com/adminjiraserver/connecting-jira-applications-to-mysql-5-6-938846854。 html

包括：

CREATE DATABASE jiradb CHARACTER SET utf8 COLLATE utf8_bin;
CREATE USER 'jiradbuser'@'%' IDENTIFIED BY 'secret';
GRANT ALL PRIVILEGES ON jiradb.* TO 'jiradbuser'@'%' IDENTIFIED BY 'secret';
flush privileges;

MySQL 可在我的本地主机端口 3306 上访问（命令 telnet 0.0.0.0 3306 很好地回答了我）

我还从 MySQL 下载了 5.1.38 connector-j，因为我的 /var/atlassian/jira 中没有 lib 文件夹，所以我用 mkdir 创建了它并解压缩了其中的 jar。

我用以下命令重新启动 Jira：

docker-compose stop jira
docker-compose rm jira
docker-compose start jira

现在，我在浏览器上访问 jira 软件地址，在设置数据库时，我输入了以下信息：

Database Connection: My Own Database 
Database Type: MySQL 5.6
Hostname: localhost
Port: 3306
Database: jiradb
Username: jiradbuser
Password: secret

当我单击“测试连接”时，它不起作用。答案是：

Error connecting to database

Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

Connection refused (Connection refused)

当我点击“测试连接”时，jira 的日志如下：

==> atlassian-jira.log <==

有什么我做错的吗？

先感谢您。

您好，感谢您的回答。这network_mode: "host"对我不起作用，因为我也使用 Traefik。但是你让我走上了正确的轨道，这个结果帮助了我：如何将本地托管的 MySQL 数据库与 docker 容器连接我的问题的解决方案是使用这个命令：

docker inspect <container-id-or-name> | grep Gateway
"Gateway": "",
            "IPv6Gateway": "",
            "Gateway": "172.18.0.1",
            "IPv6Gateway": "",

并使用 172.18.0.1 而不是“localhost”作为我本地 mySQL 数据库的“主机”字段
