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。

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:

2012-11-01 14:40:13 DEBUG: pid 3023: do_md5failed in slot 0

真正奇怪的是,日志中的 md5 哈希值会随着每个请求而变化,因此与我在 /usr/local/etc/pool_passwd 和 /usr/local/etc/pcp.conf 中设置的哈希值相比并没有什么意义

你能帮我找出配置问题吗?

发现问题了!

pg_md5它与 pgpool 一起提供了一个不正确的 md5(当我使用它时)。在我用 PostgreSQL 数据库中的 md5 在配置中替换它之后,它就可以工作了。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';

这取决于您如何使用“pg_md5”...如果您不包括用户名,那么它将生成错误的 MD5,因为毫无疑问,它在 salt 中使用:

root:/usr/local/etc# pg_md5 password1

但是,如果您使用正确的语法,那么您会自动将正确的条目放入您的 pool_password 文件中:

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