当我们远程链接mysql数据的时候会报这样的错误
Cannot create PoolableConnectionFactor
而我们的数据库链接方式是对的
解决方案:
第一:更改 “mysql” 数据库里的 “user” 表里的 “host” 项,从”localhost”改称'%'。 或者新加条记录,“host” 项为要访问的ip地址,并授权。重启mysql服务。 第二:在系统防火墙添加例外端口:3306,并允许例外。 错误提示: ERROR 1130: Host '192.168.1.3' is not allowed to connect to this MySQL server 的解决方法: 1。改表法。可能是你的帐号不允许从远程登陆,只能在localhost。这个时候只要在localhost的那台电脑,登入mysql后,更改 "mysql" 数据库里的 "user" 表里的 "host" 项,从"localhost"改称"%" 1.mysql -u root -pvmwaremysql>use mysql;mysql>update user set host = '%' where user = 'root';mysql>select host, user from user; 2. 授权法。例如,你想myuser使用mypassword从任何主机连接到mysql服务器的话。 GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION; 如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器,并使用mypassword作为密码 GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION; 3.在window自带的防火墙里的例外添加3306端口 总结: 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'; 第一句是以权限用户root登录 第二句:选择mysql库 第三句:查看mysql库中的user表的host值(即可进行连接访问的主机/IP名称) 第四句:修改host值(以通配符%的内容增加主机/IP地址),当然也可以直接增加IP地址 第五句:刷新MySQL的系统权限相关表 第六句:再重新查看user表时,有修改。。 重起mysql服务即可完成。
记得一定要重启
