mysql启动提示 access denied for user root@localhost(using pa
本文章来介绍关于mysql启动提示 access denied for user root@localhost(using password:YES) 解决办法总结,有需要的朋友可参考本文章。
关键是看:Access denied for user 'root'@'localhost' (using password: YES)'
从错误中可以看出你的权限是对localhost的访问没有放开。
于是你可以使用如下命令来放开权限:
解决办法
1. 管理员登陆系统,停止mysql服务或者结束mysqld-nt进程;
2. 进入命令行,来到mysql的安装目录.假设安装目录为 d:mysql , CMD进入命令行;
3. 运行 D:Program FilesMySQLMySQL Server 5.5binmysqld-nt --skip-grant-tables启动mysql,关闭权限的检查;
4. 运行 D:Program FilesMySQLMySQL Server 5.5binmysqladmin -u root flush-privileges password "newpassword" 重设root密码;
5. 重新启动mysql服务;
命令方式解决
方法一:
代码如下 | 复制代码 |
# /data/mysql/bin/mysqladmin -u -p # /etc/init.d/mysql restart mysql> |
解决方法二
首先计入到mysql的客户端命令行。
然后
代码如下 | 复制代码 |
grant all privileges on *.* to 'root'@'localhost' identified by '你的密码' with grant option; flush privileges; |
执行完这两条命令之后就可以了

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

Building an SQL database involves 10 steps: selecting DBMS; installing DBMS; creating a database; creating a table; inserting data; retrieving data; updating data; deleting data; managing users; backing up the database.
