每次设置root和远程访问都容易出现问题, 总结了个通用方法, 关键在于实用 step1: # mysql -u root mysql mysql> Grant all privileges on *.* to 'root'@'%' identified by 'root' with grant option; //增加远程访问权限mysql> UPDATE user SET Password=PASSWORD(’newpassword’) where USER=’root’; //增加ro
MySQL默认没有开启远程访问的权限,需要手动打开,步骤如下: 1.通过命令行登录2.mysql>update user set host = '%' where user = 'root';这里会报错,但不用管.报错内容是“ERROR 1062 (23000): Duplicate entry '%-root' for key 'PRIMARY'”3.mysql>flush privileges;4.mysql>quit 完成以上操作如果还是不能远程访问,需要在防火墙中设置一下,放行M
1. libcurl 的参考文档如下 CURLOPT_HEADERFUNCTION Pass a pointer to a function that matches the following prototype: size_t function( void *ptr, size_t size, size_t nmemb, void *userdata);. This function gets called by libcurl as soon as it has received head
1. 利用 CURLOPT_WRITEFUNCTION 设置回调函数, 利用 CURLOPT_WRITEDATA 获取数据指针 官网文档如下 CALLBACK OPTIONS CURLOPT_WRITEFUNCTION Pass a pointer to a function that matches the following prototype: size_t function( char *ptr, size_t size, size_t nmemb, void *userdata);
