MySQL遠端存取的命令 格式: mysql -h主機地址 -u使用者名稱 -p使用者密碼

首先在目標伺服器上(115.159.66.51)修改mysql的my.cnf檔案:

修改退出後,重啟mysql服務 命令:sudo service mysql restart

此時嘗試用115.159.66.51主機來串連mysql
ubuntu@VM-194-212-ubuntu:/etc/mysql$ mysql -h115.159.66.51 -uroot -pxiongchao
此時會出現無法串連的錯誤
原因:沒有對遠程主機115.159.66.51賦予訪問mysql server的許可權

賦予主機主機115.159.66.51以root的身份訪問資料許可權(註:訪問haibao資料庫):
grant all privileges on haibao.* to ‘root’@’115.159.66.51’ identified by ‘xiongchao’ with grant option;

賦予任何主機以root的身份訪問資料許可權(註:訪問haibao資料庫):
grant all privileges on haibao.* to ‘root’@’%’ identified by ‘xiongchao’ with grant option;

修改生效:
flush privileges;
