问题描述
我刚刚通过brew install mongodb将mongodb下载到了OS X 10.9.5全新的MacBookAir上.
I just downloaded mongodb onto my brandy new MacBookAir with OS X 10.9.5 by doing brew install mongodb.
我试图从Terminal运行mongod，它说"no/data/db"，所以我用sudo mkdir /data和sudo mkdir /data/db创建了它.
I tried to run mongod from Terminal and it said "no /data/db" so I created it with sudo mkdir /data and sudo mkdir /data/db.
现在正在运行mongod，我得到无法创建/打开锁定文件:/data/db/mongod.lock errno:13权限被拒绝"，但是我可以使用sudo mongod完美地运行它.
Running mongod now I get "Unable to create/open lock file: /data/db/mongod.lock errno:13 Permission denied" but I can run it perfectly fine with sudo mongod.
如何做到这一点，这样我就不必用sudo运行mongod了，而是像mongod一样简单?
How can I make it so that I don't have to run mongod with sudo, but instead just as simply mongod?
(我在最后一台计算机上有这样的感觉，但根本不记得我做了什么，而且那台计算机还是被弄乱了.)
(I had it like that on my last computer but do not remember what I did at all, and that computer was all messed up anyway.)
推荐答案
这对我有用:
sudo chmod -R 777 /data/db
然后
sudo chown -R `id -u` /data/db
-R使命令递归；我以前曾按照其他StackOverflow答案中的说明尝试过sudo chmod 777 /data/db和sudo chown `id -u` /data/db，但它们均失败了.
The -R makes the command recursive; I had previously tried both sudo chmod 777 /data/db and sudo chown `id -u` /data/db as instructed on other StackOverflow answers but they failed.
(PS，很抱歉，我知道这是一个非常老的问题，但是我在寻找问题的答案时发现了它；并且由于我设法解决了这个问题，所以我想我会把这个放在这里给任何人未来.我也不知道这两个命令中的哪一个有所作为，但它确实有效.)
(PS I'm sorry I know this is a very old question but I found it while trying to look for an answer to my problem; and since I managed to solve it I thought I'd put this here for anyone in the future. Also I'm not sure which of those two commands made the difference, but it worked.)
