问题:

I am running the AWS AMI from gitlab. I am trying to access the postgres database directly using psql. I thought I could just use the credentials in database.yml, since the rails application is working fine:

/opt/gitlab/embedded/bin/psql -U gitlab -d gitlabhq_production

But I get:

psql: FATAL:  Peer authentication failed for user "gitlab"

How can the rails app be connecting to the database while psql cannot?

回答1:

sudo -u gitlab-psql /opt/gitlab/embedded/bin/psql -h /var/opt/gitlab/postgresql/ gitlabhq_production

回答2:

googled and found an issue about this.

so, just type sudo gitlab-rails dbconsole :D

回答3:

But this one does give you full access:

sudo -u gitlab-psql psql template1

回答4:

sudo -u gitlab-psql /opt/gitlab/embedded/bin/psql -h /var/opt/gitlab/postgresql -d gitlabhq_production

回答5:

su - git
/opt/gitlab/embedded/bin/psql -U gitlab -d gitlabhq_production -h /var/opt/gitlab/postgresql

works for me with gitlab-ce and the embedded postgres. Optional for better interactive working start a bash as git. The (unix)-user git seems to be a peer to the postgresuser gitlab, authenticates without a password (/var/opt/gitlab/postgresql/data/pg_hba.conf).
