How to check status of PostgreSQL server Mac OS X
The simplest way to to check running processes:
ps auxwww | grep postgres
And look for a command that looks something like this (your version may not be 8.3):
/Library/PostgreSQL/8.3/bin/postgres -D /Library/PostgreSQL/8.3/data
To start the server, execute something like this:
/Library/PostgreSQL/8.3/bin/pg_ctl start -D /Library/PostgreSQL/8.3/data -l postgres.log
You can run the following command to determine if postgress is running:
$ pg_ctl status
You'll also want to set the
PGDATA environment variable.
Here's what I have in my
~/.bashrc file for postgres:
export PGDATA='/usr/local/var/postgres' export PGHOST=localhost alias start-pg='pg_ctl -l $PGDATA/server.log start' alias stop-pg='pg_ctl stop -m fast' alias show-pg-status='pg_ctl status' alias restart-pg='pg_ctl reload'
To get them to take effect, remember to source it like so:
$ . ~/.bashrc
Now, try it and you should get something like this:
$ show-pg-status pg_ctl: server is running (PID: 11030) /usr/local/Cellar/postgresql/9.2.4/bin/postgres
You probably did not init postgres.
If you installed using HomeBrew, the init must be run before anything else becomes usable.
To see the instructions, run
brew info postgres
# Create/Upgrade a Database If this is your first install, create a database with: initdb /usr/local/var/postgres -E utf8 To have launchd start postgresql at login: ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents Then to load postgresql now: launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist Or, if you don't want/need launchctl, you can just run: pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
Once you have run that, it should say something like:
Success. You can now start the database server using:
postgres -D /usr/local/var/postgres or pg_ctl -D /usr/local/var/postgres -l logfile start
If you are still having issues, check your firewall. If you use a good one like HandsOff! and it was configured to block traffic, then your page will not see the database.
