这里是 postgres 的新手!
我编辑了这里提到的 pg_hba.conf ,但是当我尝试重新启动 postgresql 服务时,尝试失败。以下是命令行输出,其中包含我可以收集的所有信息。
[root@arunpc modules]# service postgresql restart
Redirecting to /bin/systemctl restart postgresql.service
Job failed. See system logs and 'systemctl status' for details.
[root@arunpc modules]# systemctl status postgresql.service

Apr 8 21:29:06 arunpc pg_ctl[12677]: Examine the log output.
FWIW,这是使用的配置文件(pg_hba.conf):
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all postgres ident sameuser
local all all ident sameuser
# IPv4 local connections:
host all all 127.0.0.1 password
# IPv6 local connections:
host all all ::1 password
这里可能是什么错误?在我进行编辑之前它曾经工作得很好(因为这是一台开发机器,所以我没有做任何备份)。
我还想获得更详细的日志输出。/var/log/messages 文件中的日志消息确实要求我“检查日志输出” - 这是哪个日志输出?我还可以采取哪些其他故障排除步骤?
提前谢谢了!
