docker: Error response from daemon: Conflict. The container name “/mysql“ is already in use by conta

一、问题描述

 docker安装好MySQL后，创建实例并启动时报错：

docker: Error response from daemon: Conflict. The container name "/mysql" is already in use by container "5e1f4861f523bdff7cfcfb538d405ac506558b771f880ea4276a3104dfd49b5b". You have to remove (or rename) that container to be able to reuse that name.

二、解决

（1）移除原来的container ID（就是长长的那串数字）

docker rm + container ID 

 （2）再创建新容器

docker run -p 3306:3306 --name mysql \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:5.7

（3）测试一下有没有成功
