dbcp连接mysql ip地址127.0.0.1连接可以换成本地真正ip报
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory
网上说可能连接关闭了需要重新连接
在connection中的url参数最后加入?autoReconnect=true
结果错误
nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Could not create connection to database server. Attempted reconnect 3 times. Giving up.)
还是连不上
郁闷中
然后利用mysql -uroot -p -h 真正IP连mysql报错
mysql error number 2003
Can't connect to MySQL server xxx.xxx.xxx.xxx (10061)
噢终于明白了,远程端口mysql不认,真TMD原来在ubuntu 9.04中默认安装了mysql,默认只能本地访问,如果远程访问需要另外设置
解决办法:
授权允许远程机器以指定用户访问
GRANT all privileges ON *.* to root@ IDENTIFIED BY "root";
重启mysql
/etc/init.d/mysql restart
重新登录
mysql -uroot -p -h ip
还是不行
修改mysql配置文件
vi /etc/mysql/my.cnf
bind-address = 127.0.0.1注释掉
重启mysql
成功
