版本更新,原来user里的password字段已经变更为authentication_string
版本更新 缘故,好多网上的教程都不适用了,甚至连官网的文档也不是能够顺利操作的。
如果 MySQL 正在运行,首先杀之:
killall -TERM mysqld。
运行
mysqld_safe --skip-grant-tables &
如果此时不想被远程连接:
mysqld_safe --skip-grant-tables --skip-networking &
使用mysql连接server
更改密码:
update mysql.user set authentication_string=password('123qwe') where user='root' and Host = 'localhost';
*特别提醒注意的一点是,新版的mysql数据库下的user表中已经没有Password字段了
而是将加密后的用户密码存储于authentication_string字段
mysql> flush privileges; mysql> quit;
修改完毕。重启
killall -TERM mysqld。 mysqld_safe &
然后mysql就可以连接了
但是此时操作似乎功能不完全,还要alter user...
alter user 'root'@'localhost' identified by '123';
网文说酱紫也可以:
set password for 'root'@'localhost'=password('123'); cp mysql.server /etc/init.d/mysql chmod +x /etc/init.d/mysql chkconfig --add mysql

MySQL uses a GPL license. 1) The GPL license allows the free use, modification and distribution of MySQL, but the modified distribution must comply with GPL. 2) Commercial licenses can avoid public modifications and are suitable for commercial applications that require confidentiality.

The situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.

There are four main index types in MySQL: B-Tree index, hash index, full-text index and spatial index. 1.B-Tree index is suitable for range query, sorting and grouping, and is suitable for creation on the name column of the employees table. 2. Hash index is suitable for equivalent queries and is suitable for creation on the id column of the hash_table table of the MEMORY storage engine. 3. Full text index is used for text search, suitable for creation on the content column of the articles table. 4. Spatial index is used for geospatial query, suitable for creation on geom columns of locations table.

The main difference between MySQL and SQLite is the design concept and usage scenarios: 1. MySQL is suitable for large applications and enterprise-level solutions, supporting high performance and high concurrency; 2. SQLite is suitable for mobile applications and desktop software, lightweight and easy to embed.

Indexes in MySQL are an ordered structure of one or more columns in a database table, used to speed up data retrieval. 1) Indexes improve query speed by reducing the amount of scanned data. 2) B-Tree index uses a balanced tree structure, which is suitable for range query and sorting. 3) Use CREATEINDEX statements to create indexes, such as CREATEINDEXidx_customer_idONorders(customer_id). 4) Composite indexes can optimize multi-column queries, such as CREATEINDEXidx_customer_orderONorders(customer_id,order_date). 5) Use EXPLAIN to analyze query plans and avoid

Using transactions in MySQL ensures data consistency. 1) Start the transaction through STARTTRANSACTION, and then execute SQL operations and submit it with COMMIT or ROLLBACK. 2) Use SAVEPOINT to set a save point to allow partial rollback. 3) Performance optimization suggestions include shortening transaction time, avoiding large-scale queries and using isolation levels reasonably.
