RHEL 7 psql：严重：Ident 身份验证失败

Question

我正在尝试启动 PostgreSQL 数据库，但总是失败。

我正在尝试的命令： psql -h localhost -U postgres 导致错误： psql: FATAL: Ident authentication failed for user "postgres"。

内容/var/lib/pgsql/9.5/data/pg_hba.conf如下：

# TYPE  DATABASE        USER            ADDRESS                 METHOD

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

我最近对文件进行了更改pg_hba.conf，我假设我不必重新启动 postgres。我遵循了这一点解决方案但没有帮助。有什么建议可以解决这个问题吗？
