mysql的root賬戶,我在連接時通常用的是localhost或127.0.0.1,公司的測試服務(wù)器上的mysql也是localhost所以我想訪問無法訪問,測試暫停.
解決方法:
1,修改表,登錄mysql數(shù)據(jù)庫,切換到mysql數(shù)據(jù)庫,使用sql語句查看"select host,user from user ;"
mysql -u root -pvmwaremysql>use mysql;
mysql>update user set host = '%' where user ='root';
mysql>select host, user from user;
mysql>flush privileges;
注意:最后一句很重要,目的是使修改生效.如果沒有寫,則還是不能進(jìn)行遠(yuǎn)程連接.
2,授權(quán)用戶,你想root使用密碼從任何主機(jī)連接到mysql服務(wù)器
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'admin123' WITH GRANT OPTION;
flush privileges;
如果你想允許用戶root從ip為192.168.1.104的主機(jī)連接到mysql服務(wù)器
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.104' IDENTIFIED BY 'admin123' WITH GRANT OPTION;
flush privileges;
