我正在安装 Graphite。我在 Centos 7.3 下使用 postgresql。当我将 django 模式导入 postgres 时，我得到以下 TB：

[root@hera graphite]# PYTHONPATH=$GRAPHITE_ROOT/webapp django-admin.py migrate --settings=graphite.settings --run-syncdb

我已将石墨用户添加到 postgres 并验证了正确的 postgres 用户名、密码和数据库引擎在 local_settings.py 中。有什么我可能遗漏的想法吗？

【解决方案1】：

今天下午我碰巧在 RHEL 7.3 上遇到了同样的问题。就我而言，我编辑了 /var/lib/pgsql/data/pg_hba.conf 并更改了行：

# IPv4 local connections:
host    all             all             127.0.0.1/32            ident

到：

host    all             all             127.0.0.1/32            md5

然后重新启动 postgresql。此外，最好验证/检查您是否真的可以使用用户登录到 postgres 并拥有正确的数据库权限。
