刚接触postsql,选择了一个较新的版本10.4

[root@localhost data]# psql -U postgres postgres
psql: FATAL:  Ident authentication failed for user "postgres"

错误如上,su postgres用户是可以登录的。
查网上资料一直都是让我们修改/etc/postsqlxxxxx 文件,但是你会发现etc下面根本就没有这个文件。
10版本以后该文件位置在“/var/lib/pgsql/10/data/pg_hba.conf”,修改这个文件:

 79 # "local" is for Unix domain socket connections only
 80 local   all             all                                     md5
 81 # IPv4 local connections:
 82 host    all             all             127.0.0.1/32            ident
 83 # IPv6 local connections:
 84 host    all             all             ::1/128                 trust
 85 # Allow replication connections from localhost, by a user with the
 86 # replication privilege.
 87 local   replication     all                                     peer
 88 host    replication     all             127.0.0.1/32            ident
 89 host    replication     all             ::1/128                 ident
"/var/lib/pgsql/10/data/pg_hba.conf" 89L, 4268C

重启服务: systemctl start postgresql-10
