客户端连接时报错MySQL数据库出现：Error 1045错误时，就表明输入的用户名或密码错误被拒绝访问了。
解决办法可以分为以下几步：
1.修改mysql配置文件，使得可以无密码登录mysql
sudo vim /etc/mysql/my.cnf
在[mysqld]项下添加
skip-grant-tables
2.重启mysql服务
sudo service mysql restart
3.无密码登录mysql
mysql -uroot -p
4.修改管理员密码
use mysql;
update user set password=password(‘123‘) where user=‘root‘;
flush privileges;
exit;
5.还原配置文件
6.可以使用下面的命令登录
mysql -uroot -p123
mysql服务没问题：
并且本地的登录也能成功：
但是使用外网地址却无法登录：
于是修改了一下MySQL的配置文件：
在bind-address= 127.0.0.1这一行前加#（注释掉这行）
然后重启mysql服务：

使用Navicat就可以成功连接至数据库了.
