Linux下Mysql插入中文显示乱码解决方案

mysql -uroot -p 回车输入密码

进入mysql查看状态如下:

默认的是客户端和服务器都用了latin1,所以会乱码。

解决方案:

mysql>user mydb;

mysql>alter database mydb  character set utf8;!

上文提到了用临时方法更改数据库的字符集设置,,显示中文,但是后来发现在有的系统下并不能成功。

比如我用的debian 7.0,找了好久终于找到一个适合debian系统的解决方案,debian 7.0下测试成功,其他诸如修改client和mysql加入default-character-set=utf8的方法之类的,只适用与5.5以前的系统!

终极决绝方案,一劳永逸:

debian下mysql的字符串修改为utf8(参考:rainysia的专栏)

一、进入mysql(mysql -uroot -p),查看当前数据库字符集(status;)

二、查看当前系统版本(lsb_release -a)

三、#vim /etc/mysql/my.cnf 。(5.5以前系统)在【client】下面加入 default-character-set=utf8

在【mysqld】下面加入default-character-set=utf8

Notice:注意 如果修改后不能启动报错试试把default-character-set=utf8改为character_set_server=utf8,仅仅加入到mysqld下面的.client就不需要加了

四、#vim /etc/mysql/my.cnf 。(5.5以后系统)如下修改:

[client]
default-character-set=utf8

[mysqld]
default-storage-engine=INNODB
character-set-server=utf8
collation-server=utf8_general_ci

五、重启mysql(/etc/init.d/mysql stop   /etc/init.d/mysql  start)

六、修成成功,进入mysql查看字符集(mysql>show variables like ‘character_set_%’;)

RDS MySQL integration with Redshift zero ETL RDS MySQL integration with Redshift zero ETL Apr 08, 2025 pm 07:06 PM

Data Integration Simplification: AmazonRDSMySQL and Redshift's zero ETL integration Efficient data integration is at the heart of a data-driven organization. Traditional ETL (extract, convert, load) processes are complex and time-consuming, especially when integrating databases (such as AmazonRDSMySQL) with data warehouses (such as Redshift). However, AWS provides zero ETL integration solutions that have completely changed this situation, providing a simplified, near-real-time solution for data migration from RDSMySQL to Redshift. This article will dive into RDSMySQL zero ETL integration with Redshift, explaining how it works and the advantages it brings to data engineers and developers.

How to optimize MySQL performance for high-load applications? How to optimize MySQL performance for high-load applications? Apr 08, 2025 pm 06:03 PM

MySQL database performance optimization guide In resource-intensive applications, MySQL database plays a crucial role and is responsible for managing massive transactions. However, as the scale of application expands, database performance bottlenecks often become a constraint. This article will explore a series of effective MySQL performance optimization strategies to ensure that your application remains efficient and responsive under high loads. We will combine actual cases to explain in-depth key technologies such as indexing, query optimization, database design and caching. 1. Database architecture design and optimized database architecture is the cornerstone of MySQL performance optimization. Here are some core principles: Selecting the right data type and selecting the smallest data type that meets the needs can not only save storage space, but also improve data processing speed.

Query optimization in MySQL is essential for improving database performance, especially when dealing with large data sets Query optimization in MySQL is essential for improving database performance, especially when dealing with large data sets Apr 08, 2025 pm 07:12 PM

1. Use the correct index to speed up data retrieval by reducing the amount of data scanned select*frommployeeswherelast_name='smith'; if you look up a column of a table multiple times, create an index for that column. If you or your app needs data from multiple columns according to the criteria, create a composite index 2. Avoid select * only those required columns, if you select all unwanted columns, this will only consume more server memory and cause the server to slow down at high load or frequency times For example, your table contains columns such as created_at and updated_at and timestamps, and then avoid selecting * because they do not require inefficient query se

Understand ACID properties: The pillars of a reliable database Understand ACID properties: The pillars of a reliable database Apr 08, 2025 pm 06:33 PM

Detailed explanation of database ACID attributes ACID attributes are a set of rules to ensure the reliability and consistency of database transactions. They define how database systems handle transactions, and ensure data integrity and accuracy even in case of system crashes, power interruptions, or multiple users concurrent access. ACID Attribute Overview Atomicity: A transaction is regarded as an indivisible unit. Any part fails, the entire transaction is rolled back, and the database does not retain any changes. For example, if a bank transfer is deducted from one account but not increased to another, the entire operation is revoked. begintransaction; updateaccountssetbalance=balance-100wh
