更改为pg_hba.conf和postgresql.conf以使用pgadmin与所有用户连接后，无法启动postgres服务器

这就是我在ubantu机器上安装postgresql时遇到的错误。然后在那台机器上，我可以成功地连接它，但只要我切换到下面的文件，允许所有用户连接它。然后我注意到它不会启动

psql:无法连接到服务器：没有这样的文件或目录 服务器是否在本地运行并接受 Unix域套接字上的连接“/var/run/postgresql/.s.PGSQL.5432”

下面您可以看到postgresql.conf

data_directory = '/var/lib/postgresql/10/main'          # use data in another directory
                                        # (change requires restart)

日志文件将告诉您。我已重新安装postgres并将其更改为上述两个文件，以允许所有用户，但仍无法连接到pgAdmin。您能否帮助我退出TCP 0.0.0.0:5432 0.0.0.0:*侦听7020/postgres无法连接到服务器：无法连接到服务器：连接超时（0x0000274C/10060）服务器是否在主机“xx.xx.xx.xx”上运行并在端口5432上接受TCP/IP连接？但是在ubantu上的本地主机上，我可以连接到psql。使用

netstat-anp | grep postgres

查看它是否真的在监听0.0.0:5432，如果是，那么检查防火墙

ufw status verbose

谢谢你的回复，不过我已经在同一端口上检查了它的lisiting，但是我也禁用了防火墙。像鳗鱼一样。还是不知道是怎么回事？
