关于ubuntu:致命:用户“postgres”的密码验证失败

FATAL: password authentication failed for user “postgres”

在ubuntu中收到此错误消息。 在pg_hba.conf文件中,我尝试在不同的时间使用'ident','peer','trust','md5'。但是没有去。 请帮忙。

  • 与此相同
  • 你先做过搜索/研究吗? 显示配置文件。 解释你的尝试。 显示命令和错误。
  • 先生,你是个圣徒。 谢谢
  • 为了快速参考,在Ubuntu上重启数据库的命令是 sudo service postgresql restart 。

如果用户名和密码正确,则 md5 是正确的值。 确保重新启动数据库进程或至少在修改 pg_hba.conf 后重新加载配置。

  • muchas gracias @fog。 重启postgresql服务器解决了我的问题。
  • 如何重启数据库进程? pg_ctl restart 对我不起作用

# PostgreSQL Client Authentication Configuration File
# ===================================================
#
# Refer to the "Client Authentication" section in the PostgreSQL
# documentation for a complete description of this file. A short
# synopsis follows.
#
# This file controls: which hosts are allowed to connect, how clients
# are authenticated, which PostgreSQL user names they can use, which 致命 Option 交易失误
# databases they can access. Records take one of these forms:
#
# local DATABASE USER METHOD [OPTIONS]
# host DATABASE USER 致命 Option 交易失误 ADDRESS METHOD [OPTIONS]
# hostssl DATABASE USER ADDRESS METHOD [OPTIONS]
# hostnossl DATABASE USER ADDRESS METHOD [OPTIONS]
#
# (The uppercase items must be replaced by actual values.)
#
# The first field is the connection type: "local" is a Unix-domain
# socket, "host" is either a plain or SSL-encrypted TCP/IP socket,
# "hostssl" is an SSL-encrypted TCP/IP socket, and "hostnossl" is a
# plain TCP/IP socket.
#
# DATABASE can be "all", "sameuser", "samerole", "replication", a
# database name, or a comma-separated list thereof. The "all"
# keyword does not match "replication". Access to replication
# must be enabled in a separate record (see example below).
#
# USER can be "all", a user name, a group name prefixed with "+", or a
# comma-separated list thereof. In 致命 Option 交易失误 both the DATABASE and USER fields
# you can also write 致命 Option 交易失误 a file name prefixed with "@" to include names
# from a separate file.
#
# ADDRESS specifies the set of hosts the record matches. It can be a
# host name, or it is made up of an IP address and a 致命 Option 交易失误 CIDR mask that is
# an integer (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that
# specifies the number of significant bits in the mask. A host name
# that starts 致命 Option 交易失误 with a dot (.) matches a suffix of the actual host name.
# Alternatively, you can write an IP address and netmask in separate
# columns to specify the set of hosts. Instead of a CIDR-address, you
# can write "samehost" to match any of the server's own IP addresses,
# or "samenet" to match any address in any subnet that the server is
# directly connected to.
#
# METHOD can be "trust", "reject", "md5", "password", "gss", "sspi",
# "krb5", "ident", "peer", "pam", "ldap", "radius" or "cert". Note that
# "password" sends passwords in clear text; "md5" is preferred since
# it sends encrypted passwords.
#
# OPTIONS are a set of options for the authentication in the format
# NAME=VALUE. The available options depend on the different
# authentication methods -- refer to the "Client Authentication"
# section in the documentation for a list of which options are
# available for which authentication methods.
#
# Database and user names containing spaces, commas, quotes and other
# special characters must be quoted. Quoting one of the keywords
# "all", "sameuser", "samerole" or "replication" makes the name lose
# its special character, and just match a database or username with
# that name.
#
# This file is read on server startup and when the postmaster receives
# a SIGHUP signal. If you edit the file on a running system, you have
# to SIGHUP the postmaster for the changes to take effect. You can
# use "pg_ctl reload" to do that.

# Put your actual configuration here
# ----------------------------------
#
# If you want to allow non-local connections, you need to add more
# "host" records. In that case 致命 Option 交易失误 you will also need to make PostgreSQL
# listen on a non-local interface via the listen_addresses
# configuration parameter, or via the -i or -h command line switches.


# TYPE DATABASE USER ADDRESS METHOD

# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres peer
#host replication postgres 127.0.0.1/32 ident
#host replication postgres ::1/128 ident

当然と言えば、当然ですが、私が利用しているWindowsのリモートデスクトップは、あくまでWindows上でリモート接続するので、Windows起動前のBios / UEFI のセットアップメニューを操作できるはずがありません。

※『Chrome リモートデスクトップ』接続では、『PC の起動をカスタマイズする』項目は、表示されます。また、『今すぐ再起動』も可能です。しかし、再起動後は、ホスト側(操作される側PC)で直接操作しなくてはならないので、ご注意ください。

Linux:readonly option is set (add ! to override)错误

I_l_I 于 2018-08-15 16:54:49 发布 140187 收藏 113

在使用vim修改完一些配置文件时,当你退出时经常会出现’readonly’ option is set (add ! to override)的问题,通常有三种情况:
1、 该错误为当前用户没有权限对文件作修改,这种情况可以强制退出:q!,先取得root权限后进行修改(root的权限取得命令是:su root然后输入你的登录密码即可)
2、该文件没有正确保存退出,正在打开状态,请别人关闭后再保存
3 、 若该文件所有人都关闭了,提示有的人没有关闭,则删除该文件的临时文件则可以正常打开、修改、保存;有文件未关闭的显示:
步骤:
1、按Esc
2、输入:set noreadonly
3、即可按正常途径保存:wq
