mysql登录报错提示:ERROR 1045 (28000)的解决方法_MySQL
本文分析了mysql登录报错提示:ERROR 1045 (28000)的解决方法。分享给大家供大家参考,具体如下:
一、问题:
公司linux系统的mysql数据库root用户设置过密码,但常常用命令'mysql -u root -p'登录报错,有时又能登录。登录报错信息为:
[root@localhost ~]# mysql -u root -p Enter password: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
二、原因:数据库中存在空用户所致
三、解决方法:
1、停用mysql服务:
# service mysql stop
2、输入命令:
# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
3、登入数据库:
# mysql -u root mysql
4、
mysql> use mysql;
5、
mysql> select user,host,password from user;
结果如下:
+------+-----------------------+----------+
| user | host | password |
+------+-----------------------+----------+
| root | % | mima |
| root | localhost.localdomain | mima |
| root | 127.0.0.1 | mima |
| | localhost | |
| | localhost.localdomain | |
+------+-----------------------+----------+
6、将上面查询出来的空用户删除:
mysql> delete from user where user='';
7、退出数据库:
mysql> quit
8、启动mysql服务:
# service mysql start
9、重新用命令:
mysql -u root -p
登录,OK!

Big data structure processing skills: Chunking: Break down the data set and process it in chunks to reduce memory consumption. Generator: Generate data items one by one without loading the entire data set, suitable for unlimited data sets. Streaming: Read files or query results line by line, suitable for large files or remote data. External storage: For very large data sets, store the data in a database or NoSQL.

Backing up and restoring a MySQL database in PHP can be achieved by following these steps: Back up the database: Use the mysqldump command to dump the database into a SQL file. Restore database: Use the mysql command to restore the database from SQL files.

MySQL query performance can be optimized by building indexes that reduce lookup time from linear complexity to logarithmic complexity. Use PreparedStatements to prevent SQL injection and improve query performance. Limit query results and reduce the amount of data processed by the server. Optimize join queries, including using appropriate join types, creating indexes, and considering using subqueries. Analyze queries to identify bottlenecks; use caching to reduce database load; optimize PHP code to minimize overhead.

How to insert data into MySQL table? Connect to the database: Use mysqli to establish a connection to the database. Prepare the SQL query: Write an INSERT statement to specify the columns and values to be inserted. Execute query: Use the query() method to execute the insertion query. If successful, a confirmation message will be output.

Oracle database and MySQL are both databases based on the relational model, but Oracle is superior in terms of compatibility, scalability, data types and security; while MySQL focuses on speed and flexibility and is more suitable for small to medium-sized data sets. . ① Oracle provides a wide range of data types, ② provides advanced security features, ③ is suitable for enterprise-level applications; ① MySQL supports NoSQL data types, ② has fewer security measures, and ③ is suitable for small to medium-sized applications.
