listen_addresses (string)

Specifies the TCP/IP address(es) on which the server is to listen for connections from client applications. The value takes the form of a comma-separated list of host names and/or numeric IP addresses. The special entry * corresponds to all available IP interfaces. The entry 0.0.0.0 allows listening for all IPv4 addresses and :: allows listening for all IPv6 addresses. If the list is empty, the server does not listen on any IP interface at all, in which case only Unix-domain sockets can be used to connect to it. If the list is not empty, the server will start if it can listen on at least one TCP/IP address. A warning will be emitted for any TCP/IP address which cannot be opened. The default value is localhost, which allows only local TCP/IP "loopback" connections to be made.

1.编辑参数文件，然后重启pg

vi $PGDATA/postgresql.conf

bash 复制代码

listen_addresses = '192.168.56.10'

2.编辑pg_hba.conf，然后运行pg_ctl reload

vi $PGDATA/pg_hba.conf

bash 复制代码

host all all 192.168.56.0/24 scram-sha-256
