PG :: ConnectionBad:致命错误:用户'用户名'错误导致对等身份验证失败

Question

当我尝试使用User.connection或generic-table.connection连接到我的pg数据库时,我收到此错误

PG :: ConnectionBad:致命:用户'用户名'的对等身份验证失败

我仔细检查了我的database.yml,它看起来不错.我认为问题在于我的pg_bha.conf文件？我现在无法在我的应用程序或系统中找到此文件.

database.yml的

    development:
  adapter: postgresql
  encoding: utf8
  database: project_development
  pool: 5
  username: 
  password:

 test: &TEST
  adapter: postgresql
  encoding: utf8
  database: project_test
  pool: 5
  username: name
  password:

 production:
  adapter: postgresql
  encoding: utf8
  database: project_production
  pool: 5
  username: name
  password:

 cucumber:
   <<: *TEST
  Thanks for the help.

Answer 1

首先,找到你的pg_hba.conf:

sudo find / -name "pg_hba.conf"

我的系统上是/var/lib/pgsql/data/pg_hba.conf.

确保在pg_hba.conf中更改此行:

local all all local

至 :

local all all md5

最后,重启postgresql:

OS X:

launchctl unload ~/Library/LaunchAgents/org.postgresql.postgres.plist

launchctl load ~/Library/LaunchAgents/org.postgresql.postgres.plist

Systemd:

sudo systemctl restart postgresql.service

sysvinit的:

sudo service postgresql restart
