无法创建/打开锁定文件:/data/mongod.lock errno:13权限被拒绝 [英] Unable to create/open lock file: /data/mongod.lock errno:13 Permission denied

问题描述

如何让mongo在ec2上使用已安装的驱动器?我真的不明白.我在ec2上连接了一个以root用户身份格式化驱动器的卷，并以root用户身份启动，但是以root用户身份我无法访问?我正在Ubuntu 12.04上运行.没有其他mongo在运行

How to I get mongo to use a mounted drive on ec2? I really do not understand. I attached a volume on ec2 formatted the drive as root and start as root and yet as root I cant access? I am running on ubuntu 12.04. No other mongo is running

我看到mongo在/data中创建了一个'db'目录，即/data/db

I see that mongo made a 'db' dir in /data i.e. /data/db

cd /
ls -al
drwxr-xr-x  4 root root  4096 Mar  5 16:28 data

cd /data
ls -al
total 28
drwxr-xr-x  4 root root  4096 Mar  5 16:28 .
drwxr-xr-x 24 root root  4096 Mar  5 16:28 ..
drwxr-xr-x  2 root root  4096 Mar  5 16:28 db
drwx------  2 root root 16384 Mar  5 16:20 lost+found


sudo mkfs.ext3 /dev/xvdh
sudo mkdir /data
sudo su - -c 'echo "/dev/xvdh %s auto noatime 0 0" | sudo tee -a /etc/fstab'
sudo mount /data

sudo service mongodb start
mongodb start/running, process 17169

sudo ps -ef | grep mongod

推荐答案

我在Ubuntu ec2实例上遇到了同样的问题.我正在关注第7页的亚马逊文章:

I was having the same problem on a Ubuntu ec2 instance. I was following this amazon article on page 7:

http://d36cz9buwru1tt.cloudfront.net/AWS_NoSQL_MongoDB.pdf

/etc/mongodb.conf中的/var/lib/mongodb(主要安装位置且正在运行).当我更改为/data/db(EBS卷)时，我得到的是"errno:13许可被拒绝".

Mongodb path in /etc/mongodb.conf was set to /var/lib/mongodb (primary install location and working). When I changed to /data/db (EBS volume) I was getting 'errno:13 Permission denied'.

1. 首先我运行了sudo service mongodb stop.
2. 然后我使用ls -la查看哪个组&所有者mongodb分配给/var/lib/mongodb(现有路径)，我用chown和chgrp更改了/data/db(新路径)以匹配. (例如:sudo chown -R mongodb:mongodb /data/db)
3. 然后我将etc/mongodb.conf中的路径更新为/data/db，并删除了/var/lib/mongodb目录中的旧mongo文件.
4. 然后我跑了sudo service mongodb start并等待了大约一分钟.如果您尝试立即连接到27017，将无法连接.
5. 经过一分钟的检查/data/db(EBS量)，mongo应该已经放置了日记，mongod.lock，local.ns，local.0等.如果没有，请尝试sudo service mongodb restart并在一分钟后检查. li>

1. First I ran sudo service mongodb stop.
2. Then I used ls -la to see what group & owner mongodb assigned to /var/lib/mongodb (existing path) and I changed the /data/db (new path) with chown and chgrp to match. (example: sudo chown -R mongodb:mongodb /data/db)
3. Then I updated the path in etc/mongodb.conf to /data/db and deleted the old mongo files in /var/lib/mongodb directory.
4. Then I ran sudo service mongodb start and waited about a minute. If you try to connect to 27017 immediately you won't be able to.
5. After a minute check /data/db (EBS volume) and mongo should have placed a journal, mongod.lock, local.ns, local.0, etc. If not try sudo service mongodb restart and check a minute later.

我刚刚花了一个多小时.可能不需要更改组并删除旧文件，但这对我有用.

I just spent over a hour with this. Changing the group and deleting the old files is probably not necessary, but that's what worked for me.

This is a great video about mounting a ebs volume to ec2 instance:
