I'm on a brew install [email protected] for legacy reasons, and actually needed to: # First, close all connections, e.g. Application servers and psql connections, then brew services stop postgres killall postgres brew services start postgres. $ brew services start [email protected] Successfully started `[email protected]` (label: [email protected]) however, no postgresql server is running, but the plist file was copied to /Library/LaunchAgents $ pwd && ls homebrew. /Users/ckhall/Library/LaunchAgents [email protected] What you expected to happen.

  1. $ brew install postgresql-9.3 $ brew install postgresql-9.6 If you had the default postgresql package already installed, you might encounter some issues later on, so it would be best to get rid of it.
  2. Jan 26, 2021 To install postgres with brew I used: $ brew install postgres To see if postgres is running I can type: $ brew services Name Status User Plist postgresql stopped Then the funny thing was when I tried to start the service: $ brew services start postgres Successfully started `postgresql` (label: homebrew.mxcl.postgresql) Great! So it's running!

This is a quick guide for installing PostgreSQL (Postgres for short) on a Mac with Homebrew, and starting and stopping it with Lunchy. If you've just forked a Ruby on Rails project that requires Postgres, this tutorial will get you up and running in no time.

If you're working on a brand new Rails app and need to create a new Postgres user and database for your app, I recommend Will Jessop's tutorial or Peter Cooper's screencast.

Step 1: Install Homebrew

To make sure you have all the tools necessary for Ruby on Rails development, I recommend you follow my tutorial for installing Xcode, Homebrew, Git, RVM, and Ruby on a Mac.

Step 2: Update Homebrew

Before you install anything with Homebrew, you should always make sure it's up to date and that it's healthy:


Step 3: Install Postgres

When you install Postgres, you will see a bunch of output in your Terminal that looks like this:

I agree with Ann154, have you checked to see if your mailbox is full? If so, you will want to delete out messages. You may do this by dialing.86 to access your voicemail and option 7 to delete a message.

The resulting data saved on your phone is termed as 'cache'. Cache can be good but most of the time, some of your phone's cache are only used for one time and may stay on your phone for a long time if not used. Time to time you need to clean your cache to get rid. My phone memory is full how do i clean it. Clean up your photo library. If you’ve checked iPhone storage like we suggested.

The important sections are Build Notes, Create/Upgrade a Database, and Start/Stop PostgreSQL. Make sure to follow those instructions to the letter.

Step 4: Create/Upgrade a database

If this is your first time installing Postgres with Homebrew, you'll need to create a database with:

I copied and pasted that command directly from the Terminal output. You should do the same, in case the instructions change in the future.

Step 5: Install Lunchy

Postgresql Brew Osx

Lunchy is a helpful gem that will allow you to easily start and stop Postgres.

Step 6: Start/Stop Postgres

Once again, I'm copying and pasting the following commands from my Terminal. Note that the second command is specific to the version of Postgres that was installed on my machine. If the version number has changed since I've written this tutorial, using the command below won't work for you, so you should make sure to copy the command from your Terminal output.

Postgresql Brew Manual

Since we're using Lunchy, we don't need to run this third command:

Instead, we'll simply use this to start Postgres:

Start Postgres Mac

At this point, you should be all set to run the rake commands to create and use the database for the existing Rails app you're working on.
