我在 RHEL 7.3 虚拟机上安装了 EDB PostgreSQL 11.3 的试用版。我按照安装步骤进行，一切顺利，直到我尝试从 pgadmin 连接到数据库并得到以下信息：FATAL: no pg_hba.conf entry for host "10.2.191.84", user "system", database "postgres", SSL off

所以我设置了启用远程连接。Postgresql.conf 已经有了listen_addresses = '*'，所以我添加了

host    all             all              0.0.0.0/0                       md5
host    all             all              ::/0                            md5

现在我需要重新启动数据库。

安装说明告诉我运行systemctl restart edb-as-11但失败了：

[root@EDBPostgre0 bin]# systemctl restart edb-as-11.service
Job for edb-as-11.service failed because the control process exited with error code. See "systemctl status edb-as-11.service" and "journalctl -xe" for details.

而且最奇怪的是，我仍然可以通过psql连接到数据库。但我还需要远程连接到它。

我试图重新启动 postgresql.service 但我的机器上没有这样的东西。使用 pg_ctl 只是告诉我并指出我使用 systemctl。

我究竟做错了什么？

事实证明，我在 EDB 网站上使用了两个不同的安装指南，因为我通过 EDB 关于其中一个参数的链接遵循 EDB 安装指南到常规 postgreSQL 指南。它造成了混乱。第二次安装完美。
