Centos 安装后需要修改密码
AlTER USER 'root'@'localhost' IDENTIFIED BY '需要复杂一点的密码';
MYSQL 开启远程访问
MySQL默认禁止远程访问了
$ mysql -uroot -p
mysql> use mysql;
mysql> update user set host = '%' where user = 'root';
mysql> select host, user from user;
+-----------+------------------+
| host | user |
+-----------+------------------+
| % | root |
| localhost | debian-sys-maint |
| localhost | mysql.session |
| localhost | mysql.sys |
+-----------+------------------+
或者
#允许所有用户远程访问 修改用户名和密码为你自己的
mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'%' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;
#允许单个ip 修改用户名和密码为你自己的
mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'1.2.3.4' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;
#最后
mysql> FLUSH PRIVILEGES;
