開啟MySQL的遠(yuǎn)程訪問(wèn)權(quán)限
默認(rèn)mysql的用戶是沒(méi)有遠(yuǎn)程訪問(wèn)的權(quán)限的,因此當(dāng)程序跟數(shù)據(jù)庫(kù)不在同一臺(tái)服務(wù)器上時(shí),我們需要開啟mysql的遠(yuǎn)程訪問(wèn)權(quán)限。
主流的有兩種方法,改表法和授權(quán)法。
相對(duì)而言,改表法比較容易一點(diǎn),個(gè)人也是比較傾向于使用這種方法,因此,這里只貼出改表法
1、登陸mysql
mysql -u root -p
2、修改mysql庫(kù)的user表,將host項(xiàng),從localhost改為%。%這里表示的是允許任意host訪問(wèn),如果只允許某一個(gè)ip訪問(wèn),則可改為相應(yīng)的ip,比如可以將localhost改為192.168.1.123,這表示只允許局域網(wǎng)的192.168.1.123這個(gè)ip遠(yuǎn)程訪問(wèn)mysql。
mysql> use mysql; mysql> select host,user form user; mysql>update user set host = '%' where user ='root'; mysql>select host,user from user; mysql> flush privileges; mysql> quit;
首先查看端口是否打開 netstat -an|grep 3306
打開mysql配置文件vim /etc/mysql/mysql.conf.d/mysqld.cnf
將bind-address = 127.0.0.1注銷
重啟動(dòng)ubuntu
再次查看端口是否打開 netstat -an|grep 3306
================================
將root用戶授權(quán)給所以連接:grant all privileges on *.* to 'root'@'%' identified by 'xxxxxx';
最后一個(gè)為mysql密碼
讓權(quán)限立即生效:flush privileges;
到此所以操作完成,可以在任何主機(jī)連接此mysql數(shù)據(jù)庫(kù)服務(wù)器了。
