在服务器上安装好mysql之后,一般都需要做下面几件事情:
- 1. 启动mysql server
- 2. 设置root用户和添加一些访问用户
- 3. 设置用户权限
- 4. 配置非本地连接访问
- 5. 备份数据或者迁移数据
- 6. 一些注意事项(不断更新)
1. 启动mysql server
通常情况下,我们使用的启动命令是:
service mysqld start
常见的一个问题就是抛:Timeout error occurred trying to start MySQL Daemon
解决的办法也很简单:直接执行即可
/usr/bin/mysql_install_db
目录可能会不一样,这个默认安装一般就在这里。
查看mysql的服务状态:
/etc/rc.d/init.d/mysqld status
2. 设置root用户和添加一些访问用户
默认安装后,mysql的root账户是没有密码的。一般为了安全,都会给root设置一个密码:
mysql> update user set password=PASSWORD(’123456′) where User=’root’;
Query OK, 4 rows affected (0.00 sec)
Rows matched: 4 Changed: 4 Warnings: 0
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
3. 设置用户权限
当然,mysql是提供给用户使用的,需要新增一个用户给大家使用:
mysql> insert into mysql.user(Host,User,Password) values(‘localhost’,'admin’,password(“admin”));
Query OK, 1 row affected, 3 warnings (0.01 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
现在新增了一个用户 admin/admin, 但是用户暂时还没有分配任何的权限。
mysql> grant ALL on *.* to admin@”%” Identified by “admin”;
Query OK, 0 rows affected (0.00 sec)
%代表任何主机,当然也可以只赋予:select,insert,update,delete 这些操作权限:
mysql> grant select,insert,update,delete on *.* to admin@”%” Identified by “admin”;
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
4. 配置非本地连接访问
默认情况下,远程用户访问本地的数据库是不背允许的,需要执行命令,赋予任何主机或相关主机访问数据的权限:
mysql> update user set host = ‘%’ where user = ‘admin’;
在任何主机上都可以使用admin这个用户访问数据。
或者:
mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root’@'%’ WITH GRANT OPTION
5. 备份数据或者迁移数据
一般使用mysqldump比较方便,参考之前的一般文章:Mysql数据库的导入和导出
6. 注意事项
linux下mysql默认表名是要区分大小写的,如果需要改称不区分大小写的,需要按下面步骤修改。
- 1. 用root登录,修改 /etc/my.cnf
- 2. 在[mysqld]下加入一行: lower_case_table_names=1
- 3. 重新启动数据库即可

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.
