问题分析

在开始操作之前,需要检查以下几点:

  • 环境变量:确保相关参数已正确设置。例如:

    export PGUSER=highgoexport PGDATABASE=highgoexport PGHOST=localhostexport PGPORT=5866export PGPASSWORD=12345

    如果已在环境变量中设置,请注释或删除这些设置,否则可能导致配置冲突。

  • pg_hba.conf文件:确认文件设置正确。默认情况下,文件通常位于$PG_DATADIR/pg_hba.conf,请检查其内容是否与数据库连接需求相匹配。

  • 密码文件:确认是否已添加.pgpass文件,并确保文件权限为600,内容格式为:

    hostname:port:database:username:password

    例如:

    192.168.1.100:5866:highgo:highgo:12345
  • 解决方案

  • 环境变量设置:如果已在环境变量中设置相关参数,请注释或删除这些设置。例如:

    #source /etc/profile

    如果source命令未成功,可su -高戈重新登录。

  • pg_hba.conf配置:修改文件内容为:

    # "local" is for Unix domain socket connections onlylocal   all             all                                     trust# IPv4 local connectionshost    all             all             127.0.0.1/32            md5# IPv6 local connectionshost    all             all             ::1/128                 md5

    然后执行pg_ctlreload命令。

  • 密码文件管理:确保.pgpass文件格式正确,并设置适当的权限:

    chmod 600 .pgpass
  • 请确保所有设置均已完成后,重新启动数据库服务。
