postgresql – pgpool-II身份验证失败

我正在使用pgpool-II 3.2.1中的两个Postgresql 9.1配置为主热备用.

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/pcp.conf中设置的哈希值相比,它实际上没有意义.

你能帮我看一下配置问题吗？

这取决于你如何使用“pg_md5”…如果你不包括用户名,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
