Linux系统下实现远程连接MySQL数据库的方法教程

1、在服务器端开启远程访问
首先进入mysql数据库，然后输入下面两个命令：

grant all privileges on *.* to 'root'@'%' identified by 'password';
flush privileges;
第一个*是数据库，可以改成允许访问的数据库名称
第二个 是数据库的表名称，代表允许访问任意的表
root代表远程登录使用的用户名，可以自定义
%代表允许任意ip登录，如果你想指定特定的IP，可以把%替换掉就可以了
password代表远程登录时使用的密码，可以自定义
flush privileges;这是让权限立即生效
2、修改my.cnf配置文件
这个是mysql的配置文件，如果你无标题文章找不到在哪里的话，可以输入find /* -name my.cnf 找到

通过vim编辑该文件，找到bind-address    = 127.0.0.1这一句，然后在前面加个#号注释掉，保存退出

3、重启服务

service mysql restart
4、在本地远程连接
在终端输入：

mysql -h 服务器ip地址 -P 3306 -u root -p
然后输入密码即可。
root是第1点设置的用户名，密码也是第1点设置的密码
