Steps to setup MongoDB on Mac OS X

Tested on: MongoDB version 2.4.6 and mac 10.8.X

Installing standalone MongoDB on any machine.

STEP I

• Download mongo from official site
• Unzip it. Unzip using mac tool or on your favourite shell

tar xzf mongodb-osx-x86_64-2.4.6.tgz

• Rename the unzipped folder to mongodb

sudo mv ~/Downloads/mongodb /usr/local

• Create folder to hold data. Mongo stores data to default location ‘/data/db’. Don’t forget to set the permission. Prefer creating a user that has access to MongoDB and can start and stop MongoDB. Use this user to set as username for ‘/data/db’

sudo mkdir -p /data/db 
sudo chown yourusername /data/db

• Create folder for logging MongoDB messages. This is defined later in ‘mongod.conf’

sudo mkdir -p /var/log/mongodb

• Create/update .bash_profile

touch ~/.bash_profile
vim ~/.bash_profile

• Type the following the bash_profile

export MONGO_PATH=/usr/local/mongodb 
export PATH=$PATH:$MONGO_PATH/bin

• Restart shell and type to confirm if mongo is working

$ mongo -version
MongoDB shell version: 2.4.6

STEP II

• For auto start MongoDB

sudo touch /Library/LaunchDaemons/mongodb.plist
sudo vim /Library/LaunchDaemons/mongodb.plist

Add the following in the above file

<?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
 <plist version="1.0">
    <dict>
        <key>Label</key>
        <string>mongodb</string>
        <key>ProgramArguments</key>
        <array>
            <string>/usr/local/mongodb/bin/mongod</string>
            <string>run</string>
            <string>--config</string>
            <string>/etc/mongod.conf</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
        <key>KeepAlive</key>
        <true/>
        <key>WorkingDirectory</key>
        <string>/usr/local/mongodb</string>
        <key>StandardErrorPath</key>
        <string>/var/log/mongodb/error.log</string>
        <key>StandardOutPath</key>
        <string>/var/log/mongodb/output.log</string>
        <key>HardResourceLimits</key>
        <dict>
           <key>NumberOfFiles</key>
           <integer>1024</integer>
        </dict>
        <key>SoftResourceLimits</key>
        <dict>
            <key>NumberOfFiles</key>
            <integer>1024</integer>
        </dict>
    </dict>
 </plist>

• Create mongod.conf file

sudo touch /etc/mongod.conf
sudo vim /etc/mongod.conf

• Save the file with following contents in mongod.conf

# Store data at default /data/db
dbpath = /data/db
# Append logs to /var/log/mongodb/mongo.log
logpath = /var/log/mongodb/mongo.log
logappend = true
# Run as conventional database 
fork = true
# 25GB oplog size;
oplogSize=25600
# Only accept local connections. Note: This did not work, hence commented. Currently listens to all the interfaces.
#bind_ip = 127.0.0.1,X.X.X.X,X.X.X.X
# Choose a name for your replica set; make sure its consistent
replSet = tarzan
# Diagnostic Configurations
# http://docs.mongodb.org/manual/administration/configuration/
# Profiles if query is slower than 50ms; default is 100ms
slowms = 50
# Profile the query; sets the level to profile
profile = 3
# Verbose for logging; currently turned off; switch on when there are real issues
#verbose = true
#Level 3 logs all read and write operations
diaglog = 3
# Forces all request to be validated. Don`t use in production as this can cause performance issue. Use only when in untrusted environment.
#objcheck = true
# Profile cpu
cpu = true

 

• Now reload/load the above by typing

sudo launchctl unload /Library/LaunchDaemons/mongodb.plist
sudo launchctl load /Library/LaunchDaemons/mongodb.plist

• Test again if mongo is running

ps -ef | grep mongo
