# Postgres Cluster

This is a playground for all things Postgres-related.

In particular, this repository covers the intricacies of deploying a master-slave configuration into production.

## Vagrant Setup

What was provided by `vboxnet`:

    172.28.128.3 pgmaster

    172.28.128.4 pgslave

Feel free to change the IPs in the `Vagrantfile` as necessary, but note that certain configuration will need to modified accordingly.

## VM Method

Here are links to help you install Postgres:

- [Setup: Debian](https://www.postgresql.org/download/linux/debian/)

- [Setup: Ubuntu](https://www.postgresql.org/download/linux/ubuntu/)

- [Setup: Red Hat](https://www.postgresql.org/download/linux/redhat/)

### Postgres Master

Here are the instructions:

    # install postgres

    passwd postgres

    su - postgres

    psql

    # create sample data

    # ssh-keygen

    # ssh-copy-id postgres@172.28.128.4

    # modify pg_hba.conf

    # modify postgresql.conf

    systemctl restart postgresql

### Postgres Slave

Here are the instructions:

    # install postgres

    passwd postgres

    systemctl stop postgresql

    # modify pg_hba.conf

    # modify postgresql.conf

    cd /var/lib/postgresql/9.6

    pg_basebackup -R -h 172.28.128.3 -U replicator -D replica

    mv main main.old

    mv replica main

    # modify main/recovery.conf

    systemctl start postgresql

## Container Method

Here are links to help you install Docker:

- [Setup: Debian](https://docs.docker.com/install/linux/docker-ce/debian/)

- [Setup: Ubuntu](https://docs.docker.com/install/linux/docker-ce/ubuntu/)

- [Setup: CentOS](https://docs.docker.com/install/linux/docker-ce/centos/)

### Postgres Master

    # install docker

    docker pull postgres:9.6

    # build custom postgres

    # create pgmaster container

    docker exec -it pgmaster bash

    gosu postgres psql

    # create sample data

    # modify pg_hba.conf

    # modify postgresql.conf

    docker restart pgmaster

    docker exec -it pgmaster bash

    gosu postgres psql

### Postgres Slave

    # install docker

    docker pull postgres:9.6

    # build custom postgres

    # create pgslave container

    docker stop pgslave

    # create pgbackup container

    cd /var/lib/postgresql

    pg_basebackup -R -h 172.28.128.3 -U replicator -D replica

    chown -R postgres:postgres replica

    rm -rf data/*

    mv replica/* data/

    rmdir replica

    # modify pg_hba.conf

    docker start pgslave

    docker exec -it pgslave bash

    gosu postgres psql
