============问题描述============
老是出现错误:
A connection to the database could not be made. View the error message by opening the "\logs\error.log" log file, then go back to fix the problem.
我去看了error.log:
2013.09.26 11:40:03 org.jivesoftware.util.log.util.CommonsLogFactory - Prototype com.mysql.jdbc.CommunicationsException: Communications link failure due to underlying exception: ** BEGIN NESTED EXCEPTION ** java.net.UnknownHostException MESSAGE: [host-name] STACKTRACE: java.net.UnknownHostException: [host-name] at java.net.InetAddress.getAllByName(Unknown Source) at java.net.InetAddress.getAllByName(Unknown Source) at com.mysql.jdbc.StandardSocketFactory.connect(StandardSocketFactory.java:246) at com.mysql.jdbc.MysqlIO.<init>(MysqlIO.java:271) at com.mysql.jdbc.Connection.createNewIO(Connection.java:2771) at com.mysql.jdbc.Connection.<init>(Connection.java:1555) at com.mysql.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:285) at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at org.logicalcobwebs.proxool.DefaultConnectionBuilder.buildConnection(DefaultConnectionBuilder.java:39) at org.logicalcobwebs.proxool.Prototyper.buildConnection(Prototyper.java:159) at org.logicalcobwebs.proxool.Prototyper.sweep(Prototyper.java:102) at org.logicalcobwebs.proxool.PrototyperThread.run(PrototyperThread.java:44) ** END NESTED EXCEPTION ** Last packet sent to the server was 0 ms ago. at com.mysql.jdbc.Connection.createNewIO(Connection.java:2847) at com.mysql.jdbc.Connection.<init>(Connection.java:1555) at com.mysql.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:285) at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at org.logicalcobwebs.proxool.DefaultConnectionBuilder.buildConnection(DefaultConnectionBuilder.java:39) at org.logicalcobwebs.proxool.Prototyper.buildConnection(Prototyper.java:159) at org.logicalcobwebs.proxool.Prototyper.sweep(Prototyper.java:102) at org.logicalcobwebs.proxool.PrototyperThread.run(PrototyperThread.java:44)
不知道哪里错了。。。
mysql数据库我都完全卸载,注册表都删得一干二净了,重启电脑,又重新安装过mysql还是不行。。。
有谁配置过Openfire 的话,指导一下,哪里配置出问题了??!?!?!?
============解决方案1============
host-name你指定了吗
