Fix the locale issue

• Edit /etc/default/locale as sudo.
• Append LC_ALL="en_US.UTF-8" at the end of the file, save and quit.
• sudo locale-gen en_US en_US.UTF-8
• sudo dpkg-reconfigure locales

Install the necessary packages to install rbenv and build Ruby

Requirements

• postgresql compiled and installed
• postgres user created

su postgres
/opt/local/pgsql/bin/initdb -D /opt/local/pgsql/data

ngpestelos

Note: Based on this tutorial.

Why

There exists a _postgres account, but I could not switch to it. My solution so far is to create a postgres account to run the PostgreSQL process.

Steps

sudo dscl . -create /Groups/postgres

sudo dscl . -create /Groups/postgres PrimaryGroupID 1000

Requirements

• PostgreSQL source

Steps

Create a destination directory:

sudo mkdir -p /opt/local/pgsql

ngpestelos

Why

If, for some reason, you do not want to install PostgreSQL using Homebrew.

Steps

1. Download PostgreSQL source
2. Compile and install PostgreSQL
3. Create a postgres user from terminal
4. Initialize the database
