首先开启远程mysql访问允许
mysql -u root -p
mysql>use mysql;
mysql>select 'host' from user where user='root';
mysql>update user set host = '%' where user ='root';
mysql>flush privileges;
mysql>select 'host' from user where user='root';
到mysql的官网下载 Connector/C (libmysql) A client library for C development.
把下载的文件解压
tar xvzf mysql-connector-c-6.0.2-linux-glibc2.3-x86-32bit.tar.gz
把解压以后的include文件夹里的文件拷贝到/usr/include/mysql文件夹下
mkdir /usr/include/mysql
cp -rf include/* /usr/include/mysql
把解压以后的lib文件夹里的文件放到/usr/lib文件夹下
cp lib/* /usr/lib/
编写测试程序
[cpp]view plaincopy#include<stdio.h> #include<stdlib.h> #include"mysql/mysql.h" intmain(void) { constchar*host="59.71.72.133"; constchar*user="root"; constchar*pass=""; constchar*db="mysql"; /*定义mysql变量*/ MYSQLmysql; MYSQL_RES*rs; MYSQL_ROWrow; mysql_init(&mysql);/*初始化*/ /*连接数据库*/ if(!mysql_real_connect(&mysql,host,user,pass,db,0,NULL,0)) { printf("数据库连接失败：%s\n",mysql_error(&mysql)); }else{ printf("数据库连接成功！\n"); } char*sql="selecthost,userfromuserorderbyrand()"; if(mysql_query(&mysql,sql)!=0) {/*查询*/ printf("%s",mysql_errno(&mysql),mysql_error(&mysql)); } rs=mysql_store_result(&mysql);/*获取查询结果*/ while((row=mysql_fetch_row(rs))) {/*获取每一行记录*/ printf("%s---%s",row[0],row[1]); } mysql_free_result(rs);/*释放结果集*/ mysql_close(&mysql);/*关闭连接*/ return1; }
用以下命令使用 GCC 编译 这个 C源文件.
gcc -o mysqltest -g mysqltest.c -lmysqlclient
./mysqltest
