MAC上用Navicat连接本机Docker的Mysql8.0

花了一点时间，在MAC上实现了用Navicat连接Docker中的Mysql，使用了最新的Mysql8.0版本。

首先MAC上要安装Docker（免费版官方下载地址：Docker免费版），下载安装并运行Docker。然后打开MAC终端，按以下步骤进行：

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 test_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   test_mysql

4. 进入test_mysql容器：

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

5. 在容器内登陆Mysql:

root@a42f31094df5:/# mysql -uroot -p123456

6. 查看root等用户信息

mysql> select user,host,authentication_string from mysql.user;
+------------------+-----------+------------------------------------------------------------------------+
| user             | host      | authentication_string                                                  |
+------------------+-----------+------------------------------------------------------------------------+
| root             | %         | $A$005$!RE#bo G5=W;nzz+m82hawoLg9Y0Ixi2R/5clltxXqHCPmRXPt0YP/QuDgB |
| mysql.infoschema | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE                              |
| mysql.session    | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE                              |
| mysql.sys        | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE                              |
| root             | localhost | $A$005$Q#CKQ'AR6cT_o3-
no3BEJw4GpvTJWrLyK28RB74UXBhN.9u2QBYxA7OYBC |
+------------------+-----------+------------------------------------------------------------------------+
5 rows in set (0.00 sec)

7. 为root分配权限，以便可以远程连接：

mysql> grant all PRIVILEGES on *.* to root@'%' WITH GRANT OPTION;
Query OK, 0 rows affected (0.01 sec)

8. 使用Navicatlian连接Mysql:

点击 Test Connection, 此时会报错：

这是因为Mysql5.6以上的版本修改了Password算法，这里需要更新密码算法，操作步骤如下：

mysql> ALTER user 'root'@'%' IDENTIFIED BY '123456' PASSWORD EXPIRE NEVER;
Query OK, 0 rows affected (0.09 sec)
mysql>
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)

mysql> 

再次点击 Test Connection，连接成功：

接下来就可以使用navicat建表了。
