我试图在一台主机服务器上运行多个 mysql docker 容器。设置第一个 mysql 容器后，它工作正常。我按照相同的步骤设置第二个并将运行端口从 3306 更改为 3307 并使用 dump.sql 的不同路径。容器启动后，我无法使用带有端口的容器 ip 远程登录容器，但我能够 ping 通该 ip。它显示连接被拒绝。尝试将行 bind-address=0.0.0.0 添加到/etc/my.cnf 并重新启动容器，问题仍然相同。我可以看到第二个 mysql 容器启动并且我能够在容器上执行一些命令但是大约 1 分钟后，容器自动停止

最佳答案
设置 MYSQL_ROOT_HOST=% 以允许从任何 IP root 登录。
docker run --name mysql -p 3306:3306 \
-e MYSQL_RANDOM_ROOT_PASSWORD=yes \
-e MYSQL_ROOT_HOST=% -d mysql/mysql-server:latest
