MySQL常见问题解决办法整理
问题一:本机创建用户后,该用户无法登录。
问题描述:
通过root创建一个数据库,然后指定该数据库允许访问的用户名
mysql> CREATE DATABASE keystone;mysql> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY '123456'; mysql> FLUSH PRIVILEGES;
检查该用户是否能正常访问mysql
# mysql -u keystone -p123456 -D keystoneERROR 1045 (28000): Access denied for user 'keystone'@'localhost' (using password: YES)

解决办法:分析该授权语句,所有的权限都是赋予到'keystone'@'%'该用户上,而%的意思是允许任何IP访问,但无法解析'localhost'。假如你是在server本地登录mysql,则会弹出上述错误,'keystone'@'localhost',这时解决办法如下:
mysql> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY '123456';

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
