docker -mysql服务设置远程连接 解决1251 client does not support ..问题

　　前提：

　　安装MYSQL实例

docker pull mysql

　　

　　启动mysql（做了端口映射）

[root@localhost ~]# docker run -p 3306:3306 --name mysql02 -e MYSQL_ROOT_PASSWORD=123456 -d mysql
5cf11b6647da2f4d301020934cb8ef750d7215d3c25fb81a56d30fbfd1a24530

　　

　　言归正传：解决方案如下：

　　　在docker创建mysql容器后使用Navicat远程连接事报错：

　　操作起来：

　　先查看user表中的信息：

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

　　

host 列中的 % 表示不限制IP ； localhost表示的是本机使用   plugin非mysql_native_password 则需要修改密码

alter user 'root'@'% 'IDENTIFIED WITH mysql_native_password BY '123';
// (注意SQL语句最后加上 ;)
 
//其中 root用户 密码为123  （按照你的用户 密码对应设置既可）
 
//最后刷新生效 
 
 flush privileges;

　　

[root@localhost ~]# docker run -it --link mysql02:mysql --rm mysql sh -c 'exec mysql -h"$MYSQL_PORT_3306_TCP_ADDR" -P"$MYSQL_PORT_3306_TCP_PORT" -uroot -p"$M
YSQL_ENV_NYSQL_ROOT_PASSWORD"'
Enter password:
