mysql docker容器获取远程主机：容器运行后连接被拒绝

Question

我尝试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 并使用不同的 dump.sql 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，但我可以 ping 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，问题仍然是一样的。我可以看到第二个 mysql 容器启动，我可以在容器上执行一些命令，但大约 1 分钟后，容器自动停止

设置MYSQL_ROOT_HOST=% 允许从任何IP 登录。

docker run --name mysql -p 3306:3306 \
-e MYSQL_RANDOM_ROOT_PASSWORD=yes \
-e MYSQL_ROOT_HOST=% -d mysql/mysql-server:latest
