我在 Debian Wheezy 上安装了 mongodb-10gen v2.4.9，但出现了一个非常奇怪的现象：如果我以 root 身份运行它，它无法启动：
root@xx:~# /etc/init.d/mongodb stop
[ ok ] Stopping database: mongodb.
root@xx:~# /etc/init.d/mongodb start
[FAIL] Starting database: mongodb failed!
如果我手动运行它，我会看到它崩溃：
root@xx:~# /usr/bin/mongod --config /etc/mongodb.conf

但如果我使用 sudo 运行它，它运行正常：
root@xx:~# su - franck
franck@xx:~$ sudo /etc/init.d/mongodb start
[ ok ] Starting database: mongodb.
有人知道为什么吗？
答案1
显然 root 的区域设置不正确。
locale比较以 运行 时的输出franck与以 运行 时的输出root。您可以通过修改 来修复 root 的语言环境/root/.bashrc。
