| # Installing Postgres via Brew | |
| ## Pre-Reqs | |
| [Brew Package Manager](http://brew.sh) | |
| ## Installing | |
| 1. In your command-line run the command: `brew install postgres` | |
| 2. Read the **Caveats** section that is outputted to the Terminal. | |
| 3. Run the command: `ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents` | |
| 4. Open your zsh config file: `subl ~/.zshrc` | |
| 5. At the bottom of the file, create two new aliases to start and stop your postgres server. They could look something like this: | |
| ``` | |
| alias pg-start="launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist" | |
| alias pg-stop="launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist" | |
| ``` | |
| ### Details | |
| **What is this `ln` command I ran in my Terminal?** | |
| _from the `man ln` command_ | |
| > The ln utility creates a new directory entry (linked file) which has the same modes as the original file. It is useful for maintaining multiple copies of a | |
| file in many places at once without using up storage for the ``copies''; instead, a link ``points'' to the original copy. There are two types of links; hard | |
| links and symbolic links. How a link ``points'' to a file is one of the differences between a hard and symbolic link. | |
| **What is `launchctl`?** | |
| _from the `man launchctl` command_ | |
| >launchctl interfaces with launchd to manage and inspect daemons, angents and XPC services. |
