Recently, I have a project that need to use mongodb.

I find this post from ryan’s railscasts MongoDB and MongoMapper, which explains how to install mongodb and create a launchd that will automatically start and stop the daemon when you trun on and shutdown macbook.

However, I’d like to use macports to control the version of mongodb, and want to start and stop mongodb daemon only when I want to use it. So here are the steps.

1 use macports to install mongodb, this will take a quite long time for compling, about 1h

sudo port install mongodb

2 create configuration file and necessary directories

sudo mkdir /opt/local/var/db/mongodb_datasudo mkdir /opt/local/var/log/mongodbsudo touch /opt/local/var/log/mongodb/mongodb.logsudo mkdir /opt/local/etc/mongodb/#configuration file /opt/local/etc/mongodb/mongod.conf# Store data alongside MongoDB instead of the default, /data/db/dbpath = /opt/local/var/db/mongodb_data# Only accept local connectionsbind_ip = 127.0.0.1# Running as daemonfork = true# Take loglogpath = /opt/local/var/log/mongodb/mongodb.loglogappend = true

3 use the following code in .bashrc

alias mongostart="sudo mongod -f /opt/local/etc/mongodb/mongod.conf"mongostop_func () {# local mongopid=`ps -o pid,command -ax | grep mongod | awk '!/awk/ && !/grep/{print $1}'`;# just find a simpler way local mongopid=`less /opt/local/var/db/mongodb_data/mongod.lock`; if [[ $mongopid =~ [[:digit:]] ]]; then sudo kill -15 $mongopid; echo mongod process $mongopid terminated; else echo mongo process $mongopid not exist; fi}alias mongostop="mongostop_func"

4 use the following command to start and stop mongo

tar xzf gcc-4.6.3.tar.gz

cd gcc-4.6.3

./contrib/download_prerequisites

cd ..

mkdir objdir

cd objdir

$PWD/../gcc-4.6.3/configure --prefix=/opt/gcc-4.6.3 

make

make install
