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

Question

我正在尝试在 CentOS 7 虚拟机上配置 jira。 我使用 docker-compose 成功地启动了 Jira 的 docker 镜像:

 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 可以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，所以我使用 mkdir 创建了它，并将 jar 解压到其中。

我重新启动 Jira:

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

现在，我在浏览器上转到 jira 软件地址，在数据库设置时，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

当我点击“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)

点击“测试连接”时jira的日志如下:

有什么我做的不对吗？

Answer 1

Mysql 数据库在主机(非 docker)的 3306 端口上运行。

当 Jira 在容器内运行时。默认容器在 bridge 中运行网络模式，其中容器网络不同于主机网络。因此，容器内的本地主机与主机上的本地主机不同。

在这里你可以做两件事:

• 在您的 Jira 容器中使用 private/public-ip:3306 引用 mysql 数据库

或

• 在 host 中运行 Jira docker 容器网络模式，使容器内的本地主机与主机上的本地主机相同。因为在这种模式下容器使用主机的网络。

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

注意 network_mode: "host" 选项将告诉 docker 容器使用 host网络模式。
