docker run -p 3306:3306 --name mysql02 -e MYSQL_ROOT_PASSWORD=123456 -d mysql
上述端口已经开放了但是依然报错还是连接不上。
解决方案:
查看进程
[root@localhost 桌面]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
7c0ae18150da mysql "docker-entrypoint..." 9 hours ago Up 2 seconds 0.0.0.0:3306->3306/tcp, 33060/tcp mysql01
49074f451a0e tomcat "catalina.sh run" 12 hours ago Exited (143) 11 hours ago frosty_einstein
进入MySQL容器
[root@localhost 桌面]# docker exec -it 7c0ae18150da bash
root@7c0ae18150da:/# mysql -uroot -p123456

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'; 这里我们修改下密码
