MongoDB Configuration in Ubuntu14.04

I installed Ubuntu14.04 on the virtual machine VirtualBox and then encountered an error while deploying MongoDB.

Environment:

• System: Ubuntu (AMD64 server version) on VirtualBox, memory 256MB, dual core CPU.
• HDD: 8GB ext4 File System (. VDI), already used 64.5%
• Internet connection is OK, software source has been updated

Problem:

When installing Mongo-server

$ sudo apt-get install Mongodb-server

After that, the MongoDB service cannot be started

$ sudo service MongoDB start #why error?

Restart the virtual machine multiple times, delete the configuration file and reload Mongo-server multiple times

$ sudo apt-get remove–purge mongodb-server

$ sudo apt-get install Mongodb-server

Invalid.

Analysis:

Check the configuration file/etc/mongodb.conf, according to the information to trace to several directories, suspicious error items are:

1. Insufficient space, prompt to use--smallfiles parameter
2. Log directory permissions are insufficient, Access denied

The adjustment is still more cumbersome.

Attempt to manually start the Mongod process, reporting the error of space and permissions

$ mongod–f/etc/mongodb.conf #权限错误

$ sudo mongod–f/etc/mongodb.conf #空间不够

Looking at/etc/group and/etc/passwd, there are already mongodb-related items that indicate that the MONGODB account has been established.

Weigh:

The right to modify the default log directory and data files directly still may cause problems. Don't want to tangle on the level of directory permissions. by/etc/passwd know, MongoDB's hometown in/home/mongodb, then let it go back to the hometown.

Method:

Build MongoDB's home, and give it property

$ sudo mkdir–p/home/mongodb

$ sudo chown mongodb:mongodb/home/mongodb

Adjust profile, point to home, add parameter

$sudo vim/etc/mongodb.conf

...

Dbpath=/home/mongodb

Logpath=/home/mongodb/mongo.log

Smallfiles=true

...

Restart again. After this adjustment, MongoDB services have been properly maintained

$ sudo service MongoDB [start|restart|status]
