Windows平台

官网直接提供exe安装包,没有手动安装的压缩包

postgresql-14.4-1-windows-x64.exe

几个重要的安装选项

- 安装界面会指定服务程序和库两个路径,可以自己手动选择

- 指定默认账户的密码

- 选择额外的安装项(这里我选了一个JDBC驱动包,方便DBeaver访问)

 

上述安装完成之后,使用navicat进行连接访问,发现乱码失败:

参考这篇文章,发现是配置在DB目录的配置

https://blog.csdn.net/m0_59322443/article/details/122967482

配置文件位置:

D:\pgsql-14\pg_hba.conf

更改IPV4的连接的参数

# IPv4 local connections:
# host all all 127.0.0.1/32 scram-sha-256
host all all 0.0.0.0/0 scram-sha-256

另外,关闭Windows的防火墙  

再次连接时访问成功

Centos7平台安装:

Linux在红帽和Centos平台有直接对接的RPM资源,只需要执行官网上的yum命令

https://www.postgresql.org/download/linux/redhat/

但是目前官方提供的yum源仅支持Centos6,7两个版本,没有8版本

这是我以Centos7为例安装的过程:

在访问Centos平台的PGSQL也会出现此问题:

[root@centos7-1 ~]# psql -p 5432 -U postgres
psql: 错误: 连接到套接字"/var/run/postgresql/.s.PGSQL.5432"上的服务器失败:致命错误: 对用户"postgres"的对等认证失败

同样,找到PGSQL的hba配置文件:

[root@centos7-1 ~]# find / -name pg_hba.conf
/var/lib/pgsql/14/data/pg_hba.conf

  

编辑配置文件:

设置了Local本地访问PGSQL时直接进入(trust)

# "local" is for Unix domain socket connections only
#local all all peer
local all all trust
# IPv4 local connections:
#host all all 127.0.0.1/32 scram-sha-256
host all all 0.0.0.0/0 scram-sha-256

修改Postgres默认账号的密码

# 之前已经设置了trust模式
psql -U postgres # 进入后执行密码更改
ALTER USER postgres WITH PASSWORD '123456'; # 然后退出
quit

  

需要重启生效,但是发现 连接不支持授权方法

Autentication method 10 not supported

需要更改成全部trust方式

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 0.0.0.0/0 trust
# IPv6 local connections:
host all all ::1/128 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
local replication all trust
host replication all 127.0.0.1/32 trust
host replication all ::1/128 trust

  

另外在pg配置文件中:

/var/lib/pgsql/14/data/postgresql.conf

监听主机改成任意可访问:

listen_addresses = '*'
