You should now be able to connect from any local application to Postgres with this connection info: username = postgres password = postgres host = localhost port = 5432 Then, create a new user named postgres with password postgres: CREATE USER postgres WITH PASSWORD ' postgres' įinally, give this user full superuser access: ALTER USER postgres WITH SUPERUSER Īnd you're done! You can quit psql with \q. Now you can open a connection to Postgres with your current user: psql -h localhost -p 5432 -d postgres Use the following command if you're using Bash: echo ' export ' > ~ /.bashrc source ~ /.bashrcĪnd use this command if you're using Zsh: echo ' export ' > ~ /.zshrc source ~ /.zshrc Setup postgres user with password authentication Now restart PostgreSQL: brew services restart Add the Postgres Binaries to Bash/Zshīefore we log into Postgres and use the psql binary, we need to add the Postgres /bin to our PATH. ![]() local replication all trust host replication all 127.0.0.1/32 trust host replication all ::1/128 trust local replication all trust host replication all 127.0.0.1/32 trust host replication all ::1/128 trustĪnd change it to this (add the lines with md5): # TYPE DATABASE USER ADDRESS METHOD # "local" is for Unix domain socket connections only local all all trust # IPv4 local connections: host all all 127.0.0.1/32 trust host all all 127.0.0.1/32 md5 # IPv6 local connections: host all all ::1/128 trust host all all ::1/128 md5 # Allow replication connections from localhost, by a user with the # replication privilege. Go down until you see something that looks like this: # TYPE DATABASE USER ADDRESS METHOD # "local" is for Unix domain socket connections only local all all trust # IPv4 local connections: host all all 127.0.0.1/32 trust # IPv6 local connections: host all all ::1/128 trust # Allow replication connections from localhost, by a user with the # replication privilege. If you don't have the file you need to run initdb the Postgres user, edit the file e.g. To connect to a Postgres server via TCP, we need to enable md5 authentication and then create a user with a password. Now let's start Postgres: brew services start Enable md5 auth for localhost connections Run the following in your terminal: brew install Once you've got brew installed and working, we can install Postgres! Installing install Postgres versions other than the latest one, we need to specify the version. ![]() ![]() If not, you can install the package manager for mac by following their instructions on the homebrew website. If you've already got homebrew installed, you can skip this section. This weak username/password combination is ok because we'll set up Postgres to only allow connections from localhost. See this other article from me.įrom starting a clean Mac to developing backends with Postgres with it takes some setup.Īt the end of this article, you'll have PostgreSQL version 12 set up on your mac, with a user postgres with password postgres., accepting local http connections. UPDATE: I now recommend using Docker to set up Postgres on Mac.
