MYSQL教程开启MySQL的远程访问权限
MYSQL教程默认mysql的用户是没有远程访问的权限的,因此当程序跟数据库不在同一台服务器上时,我们需要开启mysql的远程访问权限.
MYSQL教程主流的有两种方法,改表法和授权法.
MYSQL教程相对而言,改表法比较容易一点,个人也是比较倾向于使用这种方法,因此,这里只贴出改表法
MYSQL教程1、登陆mysql
MYSQL教程mysql -u root -p
MYSQL教程2、修改mysql库的user表,将host项,从localhost改为%.%这里表示的是允许任意host访问,如果只允许某一个ip访问,则可改为相应的ip,比如可以将localhost改为192.168.1.123,这表示只允许局域网的192.168.1.123这个ip远程访问mysql.
MYSQL教程
mysql> use mysql;
mysql> select host,user form user;
mysql>update user set host = '%' where user ='root';
mysql>select host,user from user;
mysql> flush privileges;
mysql> quit;
MYSQL教程首先查看端口是否打开 netstat -an|grep 3306
MYSQL教程打开mysql配置文件vim /etc/mysql/mysql.conf.d/mysqld.cnf
将bind-address = 127.0.0.1注销
重启动ubuntu
再次查看端口是否打开 netstat -an|grep 3306
MYSQL教程================================
MYSQL教程将root用户授权给所以连接：grant all privileges on *.* to 'root'@'%' identified by 'xxxxxx';
最后一个为mysql密码
让权限立即生效：flush privileges;
MYSQL教程到此所以操作完成,可以在任何主机连接此mysql数据库服务器了.
