Question

我有一个运行grails 1.1（后者又使用hibernate）应用程序的Jetty 6服务器。由于有时它会下降，我希望如果发生某些事情会自动重启。所以，我听说Monit并决定尝试一下。我创建了以下配置：

check process jetty with pidfile /var/run/jetty.pid
  group nfetron
  start program = "/data/ebs/NFeTron/bin/jetty.sh start"
  stop program = "/data/ebs/NFeTron/bin/jetty.sh stop"
  if failed host "localhost" port 8090 protocol HTTP with timeout 10 seconds then restart
  if mem usage > 95% for 11 cycles then restart

嗯，问题是当Monit启动Jetty时，它无法正常运行。它无法连接到数据库，如以下日志中所示：

我经常搜索，无法找到任何面临同样问题的人。当我使用SSH（使用root用户）启动应用程序时，它可以正常工作。但是当Monit启动它时（假设是root用户），它并没有。有没有人对这个问题有任何线索？

当Monit启动时，Spring无法连接到数据库
