我正在使用由jboss和tomcat服务器访问的postgres数据库。 我的服务器意外重启，然后postgres服务没有显示在服务列表中。 当我尝试使用pgadminIII打开postgres本地主机服务器时，它显示以下错误：
Server doesn't listen
The server doesn't accept connections: the connection library reports
could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5432? could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432?
If you encounter this message, please check if the server you're trying to contact is actually running PostgreSQL on the given port. Test if you have network connectivity from your client to the server host using ping or equivalent tools. Is your network / VPN / SSH tunnel / firewall configured correctly?
For security reasons, PostgreSQL does not listen on all available IP addresses on the server machine initially. In order to access the server over the network, you need to enable listening on the address first.
For PostgreSQL servers starting with version 8.0, this is controlled using the "listen_addresses" parameter in the postgresql.conf file. Here, you can enter a list of IP addresses the server should listen on, or simply use '*' to listen on all available IP addresses. For earlier servers (Version 7.3 or 7.4), you'll need to set the "tcpip_socket" parameter to 'true'.
You can use the postgresql.conf editor that is built into pgAdmin III to edit the postgresql.conf configuration file. After changing this file, you need to restart the server process to make the setting effective.
If you double-checked your configuration but still get this error message, it's still unlikely that you encounter a fatal PostgreSQL misbehaviour. You probably have some low level network connectivity problems (e.g. firewall configuration). Please check this thoroughly before reporting a bug to the PostgreSQL community.
由于两个不同的服务器访问相同的数据库会出现此问题吗？

我的服务器意外重启，然后postgres服务没有 显示在服务列表中。
您无法连接，因为它未运行。您可以让多个客户端连接到PostgreSQL服务器，因为您的硬件可以支持 - 没有问题。
重新启动PostgreSQL服务。如果不能，请检查日志中的原因。如果您现在不知道PostgreSQL日志的位置，那么现在就是了解它的好时机。我无法告诉您如何重新启动服务，因为您没有说明您正在运行的操作系统或如何安装PG。检查您的文档。
