1.远程连接的时候FATAL:no pg_hba.conf entry for host ***************************** 这个问题是数据库初始化的data目录下的pg_hba.conf要加上host all all 0.0.0.0 0.0.0.0 md5,就是赋给所有IP访问权限 2.远程连接的时候FATAL:password authentication f

1.远程连接的时候FATAL:no pg_hba.conf entry for host *****************************

这个问题是数据库初始化的data目录下的pg_hba.conf要加上host all all 0.0.0.0 0.0.0.0 md5,就是赋给所有IP访问权限

2.远程连接的时候FATAL:password authentication failed for user “********”

还是更改上面的文件,还是上面那句话,md5改为trust即可。详细如下:

用jdbc连接Postgresql数据库时经常出现这个错误,然而用pgAdmin III是可以正确连接的,表明用户名和密码都是正确的。
这主要是由于用户密码认证方式引起的,Postgresql数据库安装好后默认采用md5密码加密认证方式。
解决方法:

打开Postgresql安装目录下的data文件夹,找到pg_hba.conf文件并打开。修改认证方式,将md5改为trust,然后保存。

# TYPE DATABASE USER CIDR-ADDRESS METHOD

# IPv4 local connections:
host all all 127.0.0.1/32 trust

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
