无法启动mongodb作为sudo

尝试启动时,mongodb返回与访问文件相关的错误:

当我尝试:

root @ mongo01:〜#mongodb -f /etc/mongodb.conf

它开始正常,任何想法导致问题？

谢谢

Mon Jul 25 17:03:54 [initandlisten] couldn't open /var/lib/mongodb/adrise.ns errno:13 Permission denied

这是权限问题,请运行以下命令:

sudo chown -R mongodb:mongodb /var/lib/mongodb

所以我突然遇到了这个问题,我不知道为什么.问题是upstart文件想要以用户mongodb的身份运行mongo.来自/etc/init/mongodb.conf:

if [ "x$ENABLE_MONGODB" = "xyes" ]; then exec start-stop-daemon --start --quiet --chuid mongodb --exec  /usr/bin/mongod -- --config /etc/mongodb.conf; fi

chuid部分告诉它以不同的用户身份运行,即使您以root身份运行此脚本.出于某种原因,当我ls -l进入时/var/lib/mongodb,我注意到所有文件都归root所有,这就是为什么我们的mongodb用户无法使用它们.我这样做了:

sudo chown mongodb:mongodb /var/lib/mongodb

一切都很顺利.问题首先是怎么发生的？不确定.
