# Template for PostgreSQL HA with etcd
|
|
|
|
To get started, do the following from different terminals:
|
|
|
|
```
|
|
> etcd --data-dir=data/etcd
|
|
> run.py postgresql0.yml
|
|
> run.py postgresql1.yml
|
|
```
|
|
|
|
From there, you will see a high-availability cluster start up. Test
|
|
different settings in the YAML files to see how behavior changes. Kill
|
|
some of the different components to see how the system behaves.
|
|
|
|
# Requirements on a Mac
|
|
|
|
Run the following on a Mac to install requirements:
|
|
|
|
```
|
|
brew install postgresql etcd haproxy libyaml
|
|
pip install psycopg2 pyyaml
|
|
```
|
|
|
|
# Notice
|
|
|
|
There are many different ways to do HA with PostgreSQL, see (the
|
|
docs)[https://wiki.postgresql.org/wiki/Replication,_Clustering,_and_Connection_Pooling] for a complete list.
|
|
|
|
We call this project a "template" because it is far from a one-size fits
|
|
all, or a plug-and-play replication system. It will have it's own
|
|
caveats. Use wisely.
