The server doesn't grant access to the database: the server reports
FATAL: no pg_hba.conf entry for host "192.168.0.123", user "postgres", database "postgres" FATAL: no pg_hba.conf entry for host "192.168.0.123", user "postgres", database "postgres"
PostgreSQL数据库为了安全,它不会监听除本地以外的所有连接请求,当用户通过JDBC访问是,会报一些如下的异常:
org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for host
要解决这个问题,只需要在PostgreSQL数据库的安装目录下找到/data/pg_hba.conf,找到“# IPv4 local connections:”
在其下加上请求连接的机器IP
host all all 127.0.0.1/32 md5
32是子网掩码的网段;md5是密码验证方法,可以改为trust
