错误描述如下: error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)' 出现此问题一般是mysqlserver服务没有启动的缘故,当然导致没有启动的原因有很多,比如我在树莓派上遇到的就是内存不足,怎么 都无法启动服务. 查看mysql服务是否进行:ps -aux | grep mysqld 如果在运行的话就杀掉进程 sudo kill [pid] 重启服务: sud…
在MyEclipse中启动Tomcat时出现错误,错误信息例如以下: 严重: Failed to initialize end point associated with ProtocolHandler ["http-bio-8080"] 这是因为8080port冲突导致的. 关掉MyEclipse后,打开任务管理器,将名字为javaw.exe的进程所有结束.然后又一次打开MyEclipse,启动Tomcat就能够了. 这样问题就攻克了.希望对大家有帮助. watermark/2/te…
