mongo 有时在操作时候无法启动

1 **************
old lock file: /usr/local/www/mongodb/mongod.lock. probably means unclean shutdown
recommend removing file and running –repair
see: http://dochub.mongodb.org/core/repair for more information
*************

看到 old lock 就知道是因为mongo 生产文件锁 ,此时必须删除锁文件才能正常启动

使用命令:rm -f /usr/local/www/mongodb/mongod.lock 删除锁文件在进行启动，lock文件存储于 mongo 的数据所在目录下

2 Sat Jan 29 12:35:35 MongoDB starting : pid=8298 port=27017 dbpath=/var/lib/mongodb 32-bit

** NOTE: when using MongoDB 32 bit, you are limited to about 2 gigabytes of data
** see http://blog.mongodb.org/post/137788967/32-bit-limitations
解决办法：

Manually remove the lockfile: sudo rm /var/lib/mongodb/mongod.lock
Run the repair script: sudo -u mongodb /usr/bin/mongod -f /etc/mongodb.conf --repair.
