在做java web开发时常遇到的问题:mysql只能用localhost或127.0.0.1连接
解决:mysql安装完后,默认是root用户,root用户只能在服务器登录,需要分配新用户。
1.以root用户登陆mysql数据库。
2.执行一下命令分配新用户:
grant all privileges on *.* to '用户名'@'IP地址' identified by '密码';
'all privileges ':所有权限 也可以写成 select ,update等。
*.* 所有库的所有表 如 databasename.*。
IP 数据库所在的IP。
identified by ‘密码’ 表示通过密码连接。
3.执行完上述命令后用下面的命令刷新一下权限
flush privileges;
4.修改my.conf配置
[mysqld] ... bind_address=127.0.0.1 # 屏蔽掉该处 ...
5.重启启动mysql
5.1.停止:输入
sudo /etc/init.d/mysql stop
5.2.启动:输入
sudo /etc/init.d/mysql start
