根据日志文件判断为 Mongodb的错误

root@controller:/var/log/mongodb# cat mongodb.log***** SERVER RESTARTED *****Wed May 31 11:25:53.786 [initandlisten] MongoDB starting : pid=1779 port=27017 dbpath=/var/lib/mongodb 64-bit host=controllerWed May 31 11:25:53.786 [initandlisten] db version v2.4.9Wed May 31 11:25:53.786 [initandlisten] git version: nogitversionWed May 31 11:25:53.786 [initandlisten] build info: Linux orlo 3.2.0-58-generic #88-Ubuntu SMP Tue Dec 3 17:37:58 UTC 2013 x86_64 BOOST_LIB_VERSION=1_54Wed May 31 11:25:53.786 [initandlisten] allocator: tcmallocWed May 31 11:25:53.786 [initandlisten] options: { bind_ip: "192.168.1.170", config: "/etc/mongodb.conf", dbpath: "/var/lib/mongodb", logappend: "true", logpath: "/var/log/mongodb/mongodb.log", nojournal: "true", noprealloc: "true", smallfiles: "true" }************** **Unclean shutdown detected.**Please visit http://dochub.mongodb.org/core/repair for recovery instructions.*************Wed May 31 11:25:53.797 [initandlisten] exception in initAndListen: 12596 old lock file, terminatingWed May 31 11:25:53.797 dbexit: Wed May 31 11:25:53.797 [initandlisten] shutdown: going to close listening sockets...Wed May 31 11:25:53.797 [initandlisten] shutdown: going to flush diaglog...Wed May 31 11:25:53.797 [initandlisten] shutdown: going to close sockets...Wed May 31 11:25:53.797 [initandlisten] shutdown: waiting for fs preallocator...Wed May 31 11:25:53.797 [initandlisten] shutdown: closing all files...Wed May 31 11:25:53.797 [initandlisten] closeAllFiles() finishedWed May 31 11:25:53.797 dbexit: really exiting now

可以看出错误为Unclean shutdown detected. 然后根据此百度查找方法，解决方案 记得要修改数据库文件为 mongdb用户和组
