我的symfony2有问题，我不太确定是什么原因导致了问题，我正在使用FOSUserBundle来处理登录和注册。我把代码移到了一个新的服务器上，除了登录页面，一切都正常。我在登录页面上收到了闲置错误。
SQLSTATE[0806][7]无法连接到服务器：权限被拒绝Is在主机"上运行并接受TCP/IP的服务器端口5432上的连接？
我正在使用postgres，我可以对服务器进行PSQL，所以我知道这不是权限问题。此外，由于这是一个新的服务器，我用一个测试文件测试了我的PDO连接，并成功了。
有什么想法吗？
测试文件。
<?php
try {
$dbh = new PDO('pgsql:host=host;dbname=dbname', 'user', 'password');
echo 'Connected to database';
}
catch(PDOException $e)
{
echo $e->getMessage();
}
?>
有人知道这个问题是什么吗？

由于某种原因，SELinux阻止了我的请求，我的问题是一个centos问题。当我禁用它时，它开始工作。
您可以使用解除与数据库的连接
setsebool -P httpd_can_network_connect 1
禁用SELinux不是一个好主意。
