HomeDatabaseMysql Tutorialcolinux下找不到mysql.h的历程

colinux下不知道是不是还有人跟我一样的问题。特发此文。望有帮助。 1.网上基本的mysql.h都说是位于/usr/include/mysql/mysql.h,但是,colinux里找不到 2.用apt-get mysqlclient-dev;一直获取软件包失败。中间遇到 解析不了域名的问题。 需要修改DNS域名服

1.网上基本的mysql.h都说是位于/usr/include/mysql/mysql.h,但是,colinux里找不到


2.用apt-get mysqlclient-dev;一直获取软件包失败。中间遇到 解析不了域名的问题。
 需要修改DNS域名服务器。修改/etc/resolv.conf,添加DNS服务器比如nameserver 192.168.1.1;ip地址可以去查下联通或者电信的DNS IP;


3.现在可以链接上获取软件包的网站的。可是开始报404的错。把ip打开,的确,不存在。查到现在获取mysqlclient-dev的版本可能不跟其匹配;


4.只能曲线救国,上到http://dev.mysql.com/downloads/mysql#downloads;下载Debian Linux 32位;


5.dpkg -i package.deb   //安装下载到的deb文件


6.安装后。在/opt下发现了mysql。总算是有点希望了啊;


7.
//////试试编译test.cpp
#include "/opt/mysql/server-5.6/include/mysql.h"
#include
#include

#define HOSTNAME ""
#define USERNAME ""
#define PASSWORD ""
#define DATABASE ""
int main() {
    char sql[100];
    MYSQL mysql;
    sprintf(sql, "DELETE FROM test");
    mysql_init(& mysql);
    mysql_real_connect(& mysql, HOSTNAME, USERNAME, PASSWORD, DATABASE, 0, NULL, CLIENT_LOCAL_FILES);
    mysql_select_db(& mysql,"test");
    mysql_real_query(& mysql, sql, strlen(sql));
    mysql_close(& mysql);
    return 0;
}
g++ -o test test.cpp -lmysqlclient

结果又报错。/usr/bin/ld cannot find -lmysqlclient;


8.好吧,查了好久应该是缺少环境设置;、
到/etc/ld.so.conf.d文件夹下,修改conf文件或者新建自己的conf文件.加入绝对路径。
如:/opt/mysql/server-5.6/lib;
然后运行ldconfig(/sbin下的命令)


9.还是不行。最后只能把mysqlclient对应的库文件全部复制到/usr/lib
如:cp -Rf /opt/mysql/server-5.6/lib/* /usr/lib

 

10.到此,问题解决。test.cpp成功编译。colinux下不知道是不是还有人跟我一样的问题。特发此文。望有帮助。

Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Apr 16, 2025 am 12:20 AM

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL: Database Management System vs. Programming LanguageMySQL: Database Management System vs. Programming LanguageApr 16, 2025 am 12:19 AM

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL: Managing Data with SQL CommandsMySQL: Managing Data with SQL CommandsApr 16, 2025 am 12:19 AM

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.

MySQL's Purpose: Storing and Managing Data EffectivelyMySQL's Purpose: Storing and Managing Data EffectivelyApr 16, 2025 am 12:16 AM

MySQL is an efficient relational database management system suitable for storing and managing data. Its advantages include high-performance queries, flexible transaction processing and rich data types. In practical applications, MySQL is often used in e-commerce platforms, social networks and content management systems, but attention should be paid to performance optimization, data security and scalability.

SQL and MySQL: Understanding the RelationshipSQL and MySQL: Understanding the RelationshipApr 16, 2025 am 12:14 AM

The relationship between SQL and MySQL is the relationship between standard languages ​​and specific implementations. 1.SQL is a standard language used to manage and operate relational databases, allowing data addition, deletion, modification and query. 2.MySQL is a specific database management system that uses SQL as its operating language and provides efficient data storage and management.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?Apr 15, 2025 am 12:15 AM

Key metrics for EXPLAIN commands include type, key, rows, and Extra. 1) The type reflects the access type of the query. The higher the value, the higher the efficiency, such as const is better than ALL. 2) The key displays the index used, and NULL indicates no index. 3) rows estimates the number of scanned rows, affecting query performance. 4) Extra provides additional information, such as Usingfilesort prompts that it needs to be optimized.

What is the Using temporary status in EXPLAIN and how to avoid it?What is the Using temporary status in EXPLAIN and how to avoid it?Apr 15, 2025 am 12:14 AM

Usingtemporary indicates that the need to create temporary tables in MySQL queries, which are commonly found in ORDERBY using DISTINCT, GROUPBY, or non-indexed columns. You can avoid the occurrence of indexes and rewrite queries and improve query performance. Specifically, when Usingtemporary appears in EXPLAIN output, it means that MySQL needs to create temporary tables to handle queries. This usually occurs when: 1) deduplication or grouping when using DISTINCT or GROUPBY; 2) sort when ORDERBY contains non-index columns; 3) use complex subquery or join operations. Optimization methods include: 1) ORDERBY and GROUPB
