psql -h IP/localhost -U postgres -W/-w is not working

Question

我正在尝试使用以下 2 个命令连接到 postgres DB，但它无法连接到数据库：

• psql -h 10.x.x.x -U postgres -W
• psql -h localhost -U postgres -W

输出：

-bash-4.2$ psql -h 10.x.x.x -U postgres -W
Password: 
psql: could not connect to server: Connection refused
Is the server running on host "10.54.48.59" and accepting
TCP/IP connections on port 5432?
-bash-4.2$ 
-bash-4.2$ psql -h localhost -U postgres -W
Password: 
psql: FATAL:  Ident authentication failed for user "postgres"
-bash-4.2$

但是当我尝试使用没有 IP 的命令连接到数据库时，它可以工作：

-bash-4.2$ psql -U postgres -W
Password: 
psql (11.3)
Type "help" for help.
postgres=# 

我也尝试在我的 pg_hba.conf 中包含以下列表：

host    all             all             127.0.0.1/32            ident
host    all             all             127.0.0.1/32            md5
host    all             all             127.0.0.1/32            password

Answer 1

你可以试试...

host    all             all             127.0.0.1/32            trust

然后

psql -h localhost -U postgres DB
