我正在做一个项目使用django休息框架。它工作正常,但目前我得到错误

connection to server at "localhost"(127.0.0.1), port 5432 failed:  
Connection refused Is the server running on that host and accepting TCP/IP connections?

我知道postgresql的问题。因为我试过用pgadmin连接它,也给了我这个错误。
我正在使用Ubuntu操作系统,当我检查ubuntu不监听端口5432时。

使用postgresql.conf配置文件

# - Connection Settings -

listen_addresses = '*'          # what IP address(es) to listen on;
                                        # comma-separated list of addresses;
                                        # defaults to 'localhost'; use '*' for >
                                        # (change requires restart)
port = 5432                             # (change requires restart)
max_connections = 100                   # (change requires restart)
#superuser_reserved_connections = 3     # (change requires restart)
#unix_socket_directories = '/var/run/postgresql'        # comma-separated list >
                                        # (change requires restart)

当我运行service postgresql status时,它显示如下。

● postgresql.service - PostgreSQL RDBMS

下面是ss -nlt的输出:

5432端口似乎被阻塞了。如何解决此问题?

postgresql.log日志文件

nxagd54h

nxagd54h2#

问题是/etc目录需要root用户,所以我将其更改为root用户,并打开5432端口,在我的情况下/etc目录由其他用户拥有,现在一切都正常了。
