Linux编程 第一个连接mysql的C程序

1. 安装mysql client包

  sudo apt-get install libmysqlclient15-dev

2. 编写C程序

#include <stdlib.h>
#include <stdio.h>
#include "mysql.h"

int main(int argc, char *argv[]) 
{
    MYSQL *conn_ptr;
    conn_ptr = mysql_init(NULL);
    
    if (!conn_ptr) 
    {
        fprintf(stderr, "mysql_init failed\n");
        return EXIT_FAILURE;
    }
    
    conn_ptr = mysql_real_connect(conn_ptr, "localhost", "root", "mysql", "mysql", 0, NULL, 0);
    
    if (conn_ptr) 
    {
        printf("Connection success\n");
    } 
    else 
    {
        printf("Connection failed\n");
    }
    
    mysql_close(conn_ptr);
    
    return EXIT_SUCCESS;
}

3. 编译程序

  gcc -I/usr/include/mysql connect1.c -L/usr/lib/mysql -lmysqlclient -o connect1

4. 执行

  ./connect1

5. 运行结果

  Connection success
