pgadmin4 无法连接到服务器，致命：用户“postgres”的密码验证失败

Question

我尝试将 postgresql 配置为能够“远程”连接到 pgadmin4 所以我在服务器上安装了 postgresql 版本 13，并尝试通过我的笔记本电脑访问它。

但是为什么总是报错，我刚改了密码，在pgadmin4里输入用户名和密码，还是说密码认证。

这是我的 pghba.conf 文件。

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     trust

# IPv6 local connections:

# Allow replication connections from localhost, by a user with the

#db_user_namespace = off

# GSSAPI using Kerberos
#krb_server_keyfile = 'FILE:${sysconfdir}/krb5.keytab'
#krb_caseins_users = off

我仍然不知道为什么，也许有人经历过同样的事情？或者有什么想法？ 仅供参考：我打开 pgadmin4 应用程序和 url 去这个：http://127.0.0.1:60888/browser/

this is my pgadmin4 in browser

我在修改 pg_hba.conf 后解决了

来自

local   all             all                                     trust

成为

host   all             all                                     trust

现在它就像一个魅力.. 谢谢大家！ :)

在 image1 上，您更改了 Postgres linux 用户 的密码，而不是 Postgres 数据库用户的密码。尝试下一个：

sudo -u postgres psql postgres # connect to Postgres
\password postgres # change password postgres user
\q # quite from Postgres shell

然后尝试再次连接到 Postgres。
