有以下两种情况:
1、mysql未分配访问权限
格式:grant 权限 on 数据库名.表名 用户@登录主机 identified by
"用户密码"
;
grant select,update,insert,
delete
on *.* to zhxia@
'%'
identified by
'123456'
;
或者所有权限
GRANT ALL PRIVILEGES ON *.* TO zhxia@
'%'
IDENTIFIED BY
'123456'
;
接着执行
flush
privileges; 使授权生效
最后我们还需要修改mysql的配置文件
sudo vim /etc/mysql/my. cnf
2、my.ini配置中未开启网络访问功能
在旧版本中找到 skip-networking,把它注释掉就可以了
#skip-networking
在新版本中:
# Instead of skip-networking the
default
is now to listen only on
# localhost which is more compatible
and
is not less secure.
找到 :bind-address = 127.0.0.1 这一行要注释掉
#bind-address = 127.0.0.1
