1、mysql 默认root 不让远程连接，只允许本地连接，如何做到让root支持远程连接呢？

2、用mysql root登录；
root@ubuntu:/# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 39
Server version: 5.6.24-0ubuntu2 (Ubuntu)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

3、将root用户赋予可以远程连接的权限；

mysql> grant all   privileges on *.* to 'root'@'%' identified by '112233';
Query OK, 0 rows affected (0.03 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql>

4、将mysqld.cnf配置文件中的本地地址注释掉，进入vi /etc/mysql/mysql.conf.d/mysqld.cnf配置文件：

# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address           = 127.0.0.1
