MySQL在开始配置时候会遇到一些问题当然网上处理办法很多,现在我将这些问题总结供大家参考

MySQL操作

                                                                             

准备环境

MySQL

              MySQL5.6.10下载地址: http://www.xiazaiba.com/html/361.html

       Navicat for MySQL

              Navicat for MySQL下载地址:10.1.7 http://www.xiazaiba.com/html/2122.html

安装:

       解压上述压缩包,点击安装文件进行安装,因为操作比较简单,这里就不再拿出示例图

 

启动MySQL

1、  手工启动

a)         右键->[我的电脑]->管理->服务和应用程序->服务àMySQL服务启动

备注:此时我们有时候会发现第一次安装完成之后,在服务中并没有找到MySQL这个服务项目,那该怎么办呢?

解决办法:点击【开始】à打开[MySQL 5.6 Command Line Client]查找到目标位置,这个位置为MySQL的安装位置

第一步:运行”cmd”定位到MySQL的安装目录bin下,我这里的安装目录是:

C:/Program Files/MySQL/MySQL Server 5.6/bin

第二步:输入mysqld.exe –install  得到结果”Service successfully installed”服务安装成功

第三步:再次输入net start mysql

 

这个时候提示”MySQL服务正在启动..”,”MySQL服务已经启动成功”

 

              这样我们在服务中就能查看到MySQL的服务

                    

2、  命令启动

a)         运行”cmd”,直接定位到MySQL安装目录bin文件下执行【net start mysql】

连接MySQL     

可参考网址:  http://see.xidian.edu.cn/cpp/html/1441.html

1、 连接到本机上的MYSQL。

a)       首先打开DOS窗口,然后进入目录mysql/bin,再键入命令mysql -u root -p,回车后提示你输密码.注意用户名前可以有空格也可以没有空格,但是密码前必须没有空格,否则让你重新输入密码。如果刚安装好MYSQL,超级用户root是没有密码的,故直接回车即可进入到MYSQL中了,MYSQL的提示符是: mysql>

 

由上图可见进入到了Mysql操作中

2、连接到远程主机上的MYSQL假设远程主机的IP为:110.110.110.110,用户名为root,密码为abcd123。则键入以下命令:
    mysql -h110.110.110.110 -u root -p 123;(注:u与root之间可以不用加空格,其它也一样)

      

3、退出MySQL命令:exit返回到bin目录下

修改数据库密码:

1、运行”cmd”进入目录mysql/bin,然后键入以下命令
      mysqladmin -u root -password ab12
注:因为开始时root没有密码,所以-p旧密码一项就可以省略了。

注意:有时候这里会报错

 

解决办法:

直接使用/etc/mysql/debian.cnf文件中[client]节提供的用户名和密码: 
# mysql -udebian-sys-maint -p 
Enter password:  
mysql> UPDATE user SET Password=PASSWORD(’sxw’) where USER=’root’ and HOST=”localhost”; 
mysql> FLUSH PRIVILEGES; 
mysql> quit 
# mysql -uroot -p 
Enter password:  
mysql> 

 

 

以上我们就修改密码成功了,这个时候Navicat这个连接又要我们重新开始连接了

 

后面修改密码都可以这样的方式去修改

MySQL: An Introduction to the World's Most Popular DatabaseMySQL: An Introduction to the World's Most Popular DatabaseApr 12, 2025 am 12:18 AM

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.

The Importance of MySQL: Data Storage and ManagementThe Importance of MySQL: Data Storage and ManagementApr 12, 2025 am 12:18 AM

MySQL is an open source relational database management system suitable for data storage, management, query and security. 1. It supports a variety of operating systems and is widely used in Web applications and other fields. 2. Through the client-server architecture and different storage engines, MySQL processes data efficiently. 3. Basic usage includes creating databases and tables, inserting, querying and updating data. 4. Advanced usage involves complex queries and stored procedures. 5. Common errors can be debugged through the EXPLAIN statement. 6. Performance optimization includes the rational use of indexes and optimized query statements.

Why Use MySQL? Benefits and AdvantagesWhy Use MySQL? Benefits and AdvantagesApr 12, 2025 am 12:17 AM

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.

Describe InnoDB locking mechanisms (shared locks, exclusive locks, intention locks, record locks, gap locks, next-key locks).Describe InnoDB locking mechanisms (shared locks, exclusive locks, intention locks, record locks, gap locks, next-key locks).Apr 12, 2025 am 12:16 AM

InnoDB's lock mechanisms include shared locks, exclusive locks, intention locks, record locks, gap locks and next key locks. 1. Shared lock allows transactions to read data without preventing other transactions from reading. 2. Exclusive lock prevents other transactions from reading and modifying data. 3. Intention lock optimizes lock efficiency. 4. Record lock lock index record. 5. Gap lock locks index recording gap. 6. The next key lock is a combination of record lock and gap lock to ensure data consistency.

What are common causes of poor MySQL query performance?What are common causes of poor MySQL query performance?Apr 12, 2025 am 12:11 AM

The main reasons for poor MySQL query performance include not using indexes, wrong execution plan selection by the query optimizer, unreasonable table design, excessive data volume and lock competition. 1. No index causes slow querying, and adding indexes can significantly improve performance. 2. Use the EXPLAIN command to analyze the query plan and find out the optimizer error. 3. Reconstructing the table structure and optimizing JOIN conditions can improve table design problems. 4. When the data volume is large, partitioning and table division strategies are adopted. 5. In a high concurrency environment, optimizing transactions and locking strategies can reduce lock competition.

When should you use a composite index versus multiple single-column indexes?When should you use a composite index versus multiple single-column indexes?Apr 11, 2025 am 12:06 AM

In database optimization, indexing strategies should be selected according to query requirements: 1. When the query involves multiple columns and the order of conditions is fixed, use composite indexes; 2. When the query involves multiple columns but the order of conditions is not fixed, use multiple single-column indexes. Composite indexes are suitable for optimizing multi-column queries, while single-column indexes are suitable for single-column queries.

How to identify and optimize slow queries in MySQL? (slow query log, performance_schema)How to identify and optimize slow queries in MySQL? (slow query log, performance_schema)Apr 10, 2025 am 09:36 AM

To optimize MySQL slow query, slowquerylog and performance_schema need to be used: 1. Enable slowquerylog and set thresholds to record slow query; 2. Use performance_schema to analyze query execution details, find out performance bottlenecks and optimize.

MySQL and SQL: Essential Skills for DevelopersMySQL and SQL: Essential Skills for DevelopersApr 10, 2025 am 09:30 AM

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.
