我在debian Wheezy上安装了mongodb-10gen v2.4.9，而且我有这个奇怪的行为：如果我以root身份运行它，我无法启动它：
root@xx:~# /etc/init.d/mongodb stop [ ok ] Stopping database: mongodb. root@xx:~# /etc/init.d/mongodb start [FAIL] Starting database: mongodb failed! 如果我手动运行，我可以看到它崩溃：

但是如果我用sudo运行它，它工作正常：
root@xx:~# su - franck franck@xx:~$ sudo /etc/init.d/mongodb start [ ok ] Starting database: mongodb.
有没有人知道为什么？
显然root的语言环境设置不正确。
比较以franck运行时与以root运行时的locale输出。 您可以通过修改/root/.bashrc来修复root的语言环境。
