PostgreSQL
Here are some instructions for setting up PostgreSQL for use with esmBot.
1. Install PostgreSQL.
Debian/Ubuntu
sudo apt-get install postgresql postgresql-client
Alpine
doas apk add postgresql
Arch/Manjaro
sudo pacman -S postgresql
2. (Optional) Tune PostgreSQL.
PGTune is a useful tool for generating configuration files for your PostgreSQL database. It is highly recommended that you generate a config using this tool as it can increase stability and performance.
3. Create the bot user and database.
When you install PostgreSQL, it'll create a new user on your system that acts as the "superuser" of the database. You'll need to run Postgres commands as this user; however, you can run a command as that user without switching to it by using sudo.
First, you'll need to create a user that the bot can interact with as well as the database itself:
sudo su - postgres -c "createuser esmbot"
sudo su - postgres -c "createdb esmbot"
Then, launch the PostgreSQL shell for the next few commands:
sudo -u postgres psql
If you want to give the user a password, you can do so like this:
ALTER USER esmbot WITH PASSWORD 'new_password';
Once you're inside the shell, you'll need to make sure the bot owns the database and has permissions:
ALTER DATABASE esmbot OWNER TO esmbot;
The database is now accessible by the bot, but it still doesn't know how to add/get data from it. To fix that, you'll need to add some tables. Luckily, the bot comes with a script to automate this:
POSTGRES_USER=esmbot POSTGRES_DB=esmbot utils/psqlinit.sh
You're done!
Troubleshooting
If you get an error like error: permission denied for table counts when attempting to run the bot, try running these commands in the PostgreSQL shell:
\c esmbot
GRANT ALL PRIVILEGES ON guilds TO esmbot;
GRANT ALL PRIVILEGES ON counts TO esmbot;
GRANT ALL PRIVILEGES ON tags TO esmbot;
