docker 安装MySQL远程连接（阿里云服务器）

用Navicat连接本机Docker的Mysql 和一些问题

yuyingliang  2018年06月9日

1. 下载Mysql的Docker镜像：

$ docker search mysql (搜索mysql镜像)
$ docker pull mysql （下载mysql镜像，默认最新版本）

2. 运行镜像，设置root账号初始密码（123456），映射本地宿主机端口3306到Docker端口3306。测试过程没有挂载本地数据盘：

$ docker run -it --rm --name mysql -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 -d mysql

3. 查看已运行的容器：

$ docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
a42f31094df5        mysql               "docker-entrypoint.s…"   7 seconds ago       Up 6 seconds        0.0.0.0:3306->3306/tcp   mysql

4. 进入mysql容器：

docker exec -it mysql bash
root@a42f31094df5:/#

5. 在容器内登陆Mysql:

root@a42f31094df5:/# mysql -uroot -p123456 或 (mysql -uroot -p )

6. 查看用户信息

mysql> select host,user,plugin,authentication_string from mysql.user;
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
| host      | user             | plugin                | authentication_string                                                  |
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
| %         | root             | caching_sha2_password | $A$005$^]RQB}j~t!      .#v)3.UogPRFu8VJA5/GKEbK5edEQlMT5sHw2n72zYJNlIbo3 |
| localhost | mysql.infoschema | mysql_native_password | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE                              |
| localhost | mysql.session    | mysql_native_password | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE                              |
| localhost | mysql.sys        | mysql_native_password | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE                              |
| localhost | root             | caching_sha2_password | $A$005$Y6&q!59^Fmh)@-6TG58J3F5+3I/HI9L|JCadNG+-+d6W+1D_UFW+7MRD7F3 |
+-----------+------------------+-----------------------+------------------------------------------------------------------------+

备注：host为 % 表示不限制ip   localhost表示本机使用    plugin非mysql_native_password 则需要修改密码

navicat链接错误；我们继续往下看；

mysql> ALTER user 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
Query OK, 0 rows affected (0.01 sec)
mysql>
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)

7..连接数据库的
