Linux下允许MySQL 授权远程连接

1、mysql -u root -p   (root)用户名

2、mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;

3、mysql>flush privileges;

4、如果此时还无法连接，检测配置文件（/etc/mysql/mysql.conf.d/mysqld.cnf） bind-address配置是否开启，应该是关闭

#bind-address = 127.0.0.1 注释掉；

# 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　　　　　　　　　　　　　　　　　　　　<----这个

key_buffer_size = 16M
max_allowed_packet = 16M
thread_stack = 192K
thread_cache_size = 8

5、重启mysql：/etc/init.d/mysql restart;
