postgresql - pgpool-II 认证失败

Question

我在配置为主热备用的两个 PostgreSQL 9.1 中使用 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 散列随每个请求而变化，因此与我在/usr/local/etc/pool_passwd 和/usr/local/etc/中设置的相比，它并没有多大意义配置文件

你能帮我找出配置问题吗？

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
