postgresql - 配置单元:主机没有 pg_hba.conf 条目

Question

我正在尝试为 Hive 设置 PostgreSQL。这是 /var/lib/pgsql/data/pg_hba.conf 的内容:

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all   postgres                                     trust
# IPv4 local connections:
host    all   postgres             127.0.0.1/32            trust
# IPv6 local connections:
host    all   postgres             ::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

local  all  ambari,mapred md5
host  all   ambari,mapred 0.0.0.0/0  md5
host  all   ambari,mapred ::/0 md5

当我检查连接时，出现错误:

2018-04-15 23:48:49,573 - Check db_connection_check was unsuccessful. Exit code: 1. Message: Apr 15, 2018 11:48:49 PM org.postgresql.core.v3.ConnectionFactoryImpl log
WARNING: SQLException occurred while connecting to master1.local.test.org:5432
org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for host "192.168.0.10", user "hive", database "hive", SSL off

我尝试向 /var/lib/pgsql/data/pg_hba.conf 添加新行并使用 systemctl restart postgresql 重新启动 PostgreSQL (Centos 7):

host   hive   hive     192.168.0.10    trust

但是我又遇到了另一个错误:

Job for postgresql.service failed because the control process exited with error code. See "systemctl status postgresql.service" and "journalctl -xe" for details.

我尝试了这个并且它起作用了。在 IP 地址后给出子网。

例如

host    all   postgre           IP-Adress/subnet         trust
host    all   postgres          IP-Adress/subnet         trust

host    all   hive              IP-Adress/subnet         trust
host    all   hive              IP-Adress/subnet         trust
