Installing Redis 2.6.x on Ubuntu 12.04 and running with an ‘init’ script.

28 Replies

Documented here are steps to getting Redis 2.6.x running on Ubuntu 12.04 onwards using an init script (previous versions of Ubuntu should work too). The setup is intended to be used on a developer desktop/laptop rather than production infrastructure.

As ever, first download and unzip Redis from here.

cd /tmp
wget http://redis.googlecode.com/files/redis-2.6.9.tar.gz
tar -zxf redis-2.6.9.tar.gz
cd redis-2.6.9
make
sudo make install

Your Redis binaries should now be located in /usr/local/bin.

To get an init script and Redis config working cleanly with this setup, download my init and config files from my Github ‘dotfiles’ repo. My init script and redis.conf are pretty standard – intended for general development purposes.

wget https://github.com/ijonas/dotfiles/raw/master/etc/init.d/redis-server
wget https://github.com/ijonas/dotfiles/raw/master/etc/redis.conf
sudo mv redis-server /etc/init.d/redis-server
sudo chmod +x /etc/init.d/redis-server
sudo mv redis.conf /etc/redis.conf

Before you can fire up the Redis server for the first time, you’ll need add a redis user and prep a data and logging folder.

sudo mkdir -p /var/lib/redis
sudo mkdir -p /var/log/redis
sudo useradd --system --home-dir /var/lib/redis redis
sudo chown redis.redis /var/lib/redis
sudo chown redis.redis /var/log/redis

Also, you need to activate your Redis services init script by adding it to your system’s run-level configuration. That way the service will startup during the boot sequence and stop nicely during the OS’ shutdown procedure.

sudo update-rc.d redis-server defaults

You’re now ready to launch Redis server with

sudo /etc/init.d/redis-server start

Good luck!

Installing MongoDB 1.8.1 on Ubuntu 10.10 & 11.04 and running with an ‘init’ script.

Installing MongoDB 1.8.1, in my case as a developer database, is easy. This blog post just itemises all the steps so that you can pretty much blindly follow along. I’ll probably use these steps myself as I seem to be doing this regurlarly ;-)

Download the 64bit Linux binaries from here and unzip the contents to /usr/local.

cd /tmp
wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-1.8.1.tgz
sudo tar -zxf /tmp/mongodb-linux-x86_64-1.8.1.tgz -C /usr/local

Setup some symbolic links.

sudo ln -s /usr/local/mongodb-linux-x86_64-1.8.1 /usr/local/mongodb
sudo ln -s /usr/local/mongodb/bin/bsondump /usr/local/bin/bsondump
sudo ln -s /usr/local/mongodb/bin/mongo /usr/local/bin/mongo
sudo ln -s /usr/local/mongodb/bin/mongod /usr/local/bin/mongod
sudo ln -s /usr/local/mongodb/bin/mongodump /usr/local/bin/mongodump
sudo ln -s /usr/local/mongodb/bin/mongoexport /usr/local/bin/mongoexport
sudo ln -s /usr/local/mongodb/bin/mongofiles /usr/local/bin/mongofiles
sudo ln -s /usr/local/mongodb/bin/mongoimport /usr/local/bin/mongoimport
sudo ln -s /usr/local/mongodb/bin/mongorestore /usr/local/bin/mongorestore
sudo ln -s /usr/local/mongodb/bin/mongos /usr/local/bin/mongos
sudo ln -s /usr/local/mongodb/bin/mongosniff /usr/local/bin/mongosniff
sudo ln -s /usr/local/mongodb/bin/mongostat /usr/local/bin/mongostat

The first “ln -s” above sets up a handy symbolic link between the versioned mongodb folder and its unversioned counterpart. When 10Gen release updates, say version 1.8.2, all you need to do is download, unzip, and link the ’1.8.2 mongodb folder’ to the unversioned folder and ‘hey presto’ everything should just work.

To get an init script working cleanly with this setup, download mine from my Github ‘dotfiles’ repo. Please note – my init script enables journaling and the REST interface (on line 51).

wget https://github.com/ijonas/dotfiles/raw/master/etc/init.d/mongod
sudo mv mongod /etc/init.d/mongod
sudo chmod +x /etc/init.d/mongod

You’ll need to add a mongodb user and prep some folders

sudo useradd mongodb
sudo mkdir -p /var/lib/mongodb
sudo mkdir -p /var/log/mongodb
sudo chown mongodb.mongodb /var/lib/mongodb
sudo chown mongodb.mongodb /var/log/mongodb

Also, you need to activate your MongoDB service’s init script by adding it to your system’s run-level configuration. That way the service will startup during the boot sequence and stop nicely during the OS’ shutdown procedure.

sudo update-rc.d mongod defaults

Lastly to launch MongoDB

/etc/init.d/mongod start

Good luck!

UPDATE: Since April 6 Ubuntu now has prefabbed packages containing MongoDB 1.8.1, maintained by 10Gen. See the instruction below.
