You need to specify one of MYSQL_ROOT_PASSWORD, MYSQL_ALLOW_EMPTY_PASSWORD and MYSQL_RANDOM_ROOT_PASSWORD
<--
# 密码参数没有设置
# MYSQL_ROOT_PASSWORD设置root密码
# MYSQL_ALLOW_EMPTY_PASSWORD允许密码为空
# MYSQL_RANDOM_ROOT_PASSWORD 随机生成密码
docker container rm mysql-test

# 链接成功, 安装完成
如果想安装msyql5.6的版本, 可以docker pull mysql:5.6, docker查看镜像历史版本的命令好像没有找到, 只找到了一个查询的docker镜像查看
配置远程登录
docker的mysql已经配置了root用户远程登录, 但是使用的是cacheing_sha2_password加密, navicat,sqlyog登录不上, 修改加密方式
use mysql;
# 查看用户及访问权限
mysql> select user,host from user;
-->
+------------------+-----------+
| user | host |
+------------------+-----------+
| root | % |
| mysql.infoschema | localhost |
| mysql.session | localhost |
| mysql.sys | localhost |
| root | localhost |
+------------------+-----------+
5 rows in set (0.00 sec)
<--
# docker中的mysql已经开启了远程访问权限,
# 修改加密方式, by 后面的root为的密码
alter user 'root'@'%' identified with mysql_native_password by 'root';
安装msyql5.7
docker run --name mysql5.7 -v /dk/mysql5:/var/lib/mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7
