MySQL手册_PHP
手册
安装后期的设置和测试1. 初始化授权表
./scripts/mysql_install_db
mysql_install_db在mysql数据库里创建6个表(user,db,host,tables,priv,columns,priv和func)初始权限.这些权限允许MySQL root用户做任何事并允许任何人建立或使用一个名字以'test'或'test_'开始的数据库.
mysql_install_db仅在第一次安装MySQL时需要运行,若升级安装,可以跳过这一步.
2. 启动mysql服务器
cd mysql_installation_directory
bin/safe_mysqld &
3. 使用mysqladmin证实服务器正在运行
mysqladmin version
mysqladmin variables
4. 关掉服务器
BINDIR/mysqladmin -u root shutdown
5. 运行一些简单的测试证实服务器正在工作
BINDIR/mysqlshow
BINDIR/mysqlshow 表名
基本操作
1. 连接与断开服务者
mysql -h host -u user -p
Enter password:******
若成功则出现 mysql> 提示符
在mysql>提示符下,输入help,显示帮助信; 输入quit退出连接.
2. 创建并使用一个数据库
mysql> CREATE DATABASE tmpDB;
创建数据库tmpDB
mysql> USE tmpDB; 或者 shell> mysql -h host -u user -p tmpDB;
将数据库tmpDB指定为当前的数据库
mysql> SHOW TABLES; 显示当前数据库中的数据表
mysql> CREATE TABLE student (name VARCHAR(20),sex CHAR(1),birth DATE); 创建表student;
mysql> DESCRIBE student; 查看表student的表结构
mysql> INSERT INTO student VALUES('Rose','f','1990-03-02'); 在表student中插入一条记录
mysql> select * from student; 检索表中的所有记录;

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.

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 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.

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
