本文详细介绍了在Docker中启动MySQL数据库遇到初始化错误的解决过程，包括错误信息解析、官方文档查阅及正确启动参数设置，确保数据库服务正常运行。

docker 启动数据库异常

1.docker启动数据库时出现异常，爆出这样的错误：

首先运行docker

[root@zpjeck ~]# docker run -d mysql
238aedcdc9c42517299fefe6534ed6176d0f8e3e072f7f56138e286f4d671d4f

紧接着查看docker是否启动成功：

[root@zpjeck ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
238aedcdc9c4 mysql "docker-entrypoint..." 21 seconds ago Exited (1) 20 seconds ago relaxed_khorana

2.查看错误日志

[root@zpjeck ~]# docker logs 238aedcdc9c4
error: database is uninitialized and password option is not specified
You need to specify one of MYSQL_ROOT_PASSWORD, MYSQL_ALLOW_EMPTY_PASSWORD and MYSQL_RANDOM_ROOT_PASSWORD

3.根据官方文档显示启动时需要指定密码

$ docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag

... where some-mysql is the name you want to assign to your container, my-secret-pw is the password to be set for the MySQL root user and tag is the tag specifying the MySQL version you want. See the list above for relevant tags.

4.正确的启动方式：

[root@zpjeck ~]# docker run --name mysql_01 -e MYSQL_ROOT_PASSWORD=123456 -d mysql
e06e25408eb6d623bc166bed97996445f6db32e4397a163920828a6ad7aed31b
[root@zpjeck ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e06e25408eb6 mysql "docker-entrypoint..." 7 seconds ago Up 6 seconds 3306/tcp, 33060/tcp mysql_01
docker中启动数据就算成功了
