# Mysql5.7和8.0在Docker上的使用

8.0版本
> 可以跟上正确的版本号
```shell
docker run -p 3306:3306 --name mysql8-test \
-v /usr/local/docker/mysql/mysql-files:/var/lib/mysql-files \
-v /usr/local/docker/mysql/conf:/etc/mysql/conf.d \
-v /usr/local/docker/mysql/logs:/var/log/mysql \
-v /usr/local/docker/mysql/data:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:latest
```

5.7版本

```shell
docker run -p 3306:3306 --name mysql5.7-test \
-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:5.7.42
```

区别在于配置文件的路径不同

8版本是`/etc/mysql/conf.d`  

5.7版本是`/etc/mysql`

## 查看用户信息，修改密码

```sql
select host,user,plugin,authentication_string from mysql.user; 
```

修改root密码

```sql
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456'; 
```

修改root密码后再次查询用户信息，这个时候就可以远程连接成功了

## 报错日志

这个是在mysql8的镜像上启动容器，在run命令的时候挂载配置文件使用了/etc/mysql，报了以下错误

```sh
[Note] [Entrypoint]: Entrypoint script for MySQL Server 8.0.33-1.el8 started.
[ERROR] [Entrypoint]: mysqld failed while attempting to check config
        command was: mysqld --verbose --help --log-bin-index=/tmp/tmp.ixUqkEJ6Yi
        mysqld: Can't read dir of '/etc/mysql/conf.d/' (OS errno 2 - No such file or directory)
mysqld: [ERROR] Stopped processing the 'includedir' directive in file /etc/my.cnf at line 36.
mysqld: [ERROR] Fatal error in defaults handling. Program aborted!
```

删除错误容器，重新启一个容器，把挂载配置文件目录的地方改一下就可以了
