I'm starting to do some ruby development on my trusty (so far) Dell XPS 13. Time to get my stack set up. First order of business is Postgresql. Then Ruby, then rails, then it's go time. Let's get started!
For postgres, first update and get the packages you'll need:
sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install postgresql postgresql-contrib pgadmin3
I don't know about you, but for local development on my laptop I don't like to set up a password for postgres. Let's set that up.
sudo -u postgres psql ALTER USER postgres PASSWORD 'newpassword';
If you chose '' in the above you'll have no password so there's one more step to take in order to connect locally. Pop open your editor of choice and modify the pg_hba.conf file. (For me that was located in /etc/postgresql/9.3/main/pg_hba.conf)
You'll want to make sure you entries look similar to this:
local all postgres trust
Here's the part of the file you need to alter:
84 # Database administrative login by Unix domain socket 85 local all postgres trust 86 87 # TYPE DATABASE USER ADDRESS METHOD 88 89 # "local" is for Unix domain socket connections only 90 local all all peer 91 # IPv4 local connections: 92 host all all 127.0.0.1/32 trust 93 # IPv6 local connections: 94 host all all ::1/128 trust
One last thing you'll optionally want to do is uncomment the line in /etc/postgresql/9.3/main/postgresql.conf where postgres listens. This might not be necessary but let's get it done anyway:
listen_addresses = 'localhost' # what IP address(es) to listen on;
With that out of the way let's give postgres as restart
sudo /etc/init.d/postgresql restart
And now you should be able to connect to postgres via the command line or pgadmin3.
Last thing. If you're going to eventually install the pg gem on ubuntu, you'll need to install the postgresql dev packages. Might as well do that now:
sudo apt-get install libpq-dev
With that all done you should be set. Give it a try from pgadmin3, your client of choice, or the command line
