Question

我正在使用配置为主热备用的两个PostgreSQL 9.1中的pgpool-II 3.2.1。

当尝试从PGAdmin进行身份验证时，我得到：

Error connecting to the server: FATAL:  password authentication failed for user "postgres"

在pgpool日志中，我看到：

真正奇怪的是，日志中的md5哈希值会随着每个请求而变化，所以与我在/ usr / local / etc / pool_passwd和/ usr / local / etc /中设置的哈希值相比，它实际上没有意义pcp.conf

你能帮我看一下配置问题吗？

发现了问题！

与pgpool一起发货的

pg_md5生成了一个不正确的md5（当我使用它时）。在我使用PostgreSQL DB中的md5替换配置后，它工作了。您可以通过运行以下SQL查询来获取DB md5：

select passwd from pg_shadow where usename = 'username';

Answer 2

这取决于您如何使用＆＃34; pg_md5＆＃34; ...如果您不包含用户名，那么它将生成错误的MD5，因为毫无疑问，它在盐中使用：

root:/usr/local/etc# pg_md5 password1
7c6a180b36896a0a8c02787eeafb0e4c

但是如果您使用正确的语法，那么您将获得自动放入pool_password文件的正确条目：

root:/usr/local/etc# pg_md5 -m -u greg password1
root@1:/usr/local/etc# grep greg: pool_passwd
greg:md53c5b45b54c89f8af9074a2ad371e2c12
