1、准备测试环境,修改password_encryption_type 。如下 [omm@db1 ~]$ cd $PGHOME [omm@db1 db1]$ cat pg_hba.conf # TYPE DATABASE USER ADDRESS METHOD # "local" is for Unix domain socket connections only local all all trust host miao dbmt 192.168.3.25/32 sha256 # IPv4 local connections:...
2.启用密码验证 #password_encryption = on改为password_encryption = on 3.可访问的用户ip段 root@server2-virtual-machine:~# vi /etc/postgresql/9.1/main/pg_hba.conf ,并在文档末尾加上以下内容 # to allow your client visiting postgresql server host all all 0.0.0.0 0.0.0.0 md5 4.重启PostgreSQL数...
password_encryption参数决定了密码怎么被hash。默认为md5,修改为scram-sha-256,步骤如下: --查询当前参数值 postgres=# SELECT name,setting,source,enumvals FROM pg_settings WHERE name = 'password_encryption'; name | setting | source | enumvals ---+---+---+--- password_encryption | md5 | defa...

在psql客户端执行:show password_encryption可以查看使用哪种加密方式,是md5还是scram-sha-256。psql将密码hash加密后再发起alter命令。并不是说在日志文件中不会再出现密码了。最明智的办法是将log_min_error_statement设置为panic以便阻止将错误查询记录到日志文件中。另外一个安全方式:使用syslog将Log发送到安全的服务...
