Changing these pillar values are the only actual changes to Tildes
code/config needed, but if you're upgrading an existing version from 10
to 12 you will need to do some manual steps. The below should cover it -
lines starting with a * are descriptions of things you need to do, while
the rest are actual commands to run:
sudo apt-get install postgresql-12
sudo systemctl stop postgresql@10-main.service
sudo systemctl stop postgresql@12-main.service
cd /var/lib/postgresql
sudo -u postgres /usr/lib/postgresql/12/bin/pg_upgrade -b /usr/lib/postgresql/10/bin/ -B /usr/lib/postgresql/12/bin/ -d /var/lib/postgresql/10/main/ -D /var/lib/postgresql/12/main/ -o '-c config_file=/etc/postgresql/10/main/postgresql.conf' -O '-c config_file=/etc/postgresql/12/main/postgresql.conf'
* Change pillar value to 12, and run salt
sudo systemctl stop postgresql@10-main.service
* Edit /etc/postgresql/12/main/postgresql.conf and change port to 5432
sudo systemctl restart postgresql@12-main.service
sudo -u postgres ./analyze_new_cluster.sh
* After verifying the new version seems to be working, clean up the old version:
sudo apt-get remove postgresql-10
sudo rm -rf /usr/lib/postgresql/10/
sudo rm -rf /var/lib/postgresql/10/
sudo rm -rf /etc/postgresql/10/
Some of these states were built entirely around a single-server approach
(Prometheus + monitoring being on the same server as the site), and the
files have needed modifications to work with a separate monitoring
server.
This updates the states so that it should all happen as expected in all
types of environments.
