httpd:无法可靠地确定服务器的完全限定域名，使用 127.0.0.1 作为 ServerName [英] httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

问题描述

我尝试在 CentOS 5.0 上重新启动我的 Apache 服务器并收到此消息:

I tried to restart my Apache server on CentOS 5.0 and got this message:

httpd:无法可靠地确定服务器的完全限定域名，使用 127.0.0.1 作为 ServerName

httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

这是/etc/hosts文件:

127.0.0.1    server4-245    server4-245.com    localhost.localdomain localhost
::1        localhost6.localdomain6 localhost6

这是 /etc/sysconfig/network 文件:

NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=server4-245

我在 Apache httpd.conf 文件中也有这个:

I also have this in the Apache httpd.conf file:

ServerName localhost

但是，当我重新启动 Apache 时，我仍然收到第一条错误消息.

However, I still get the first error message when I restart Apache.

推荐答案

您的主机文件不包含有效的 FQDN，localhost 也不是 FQDN.FQDN 必须包含主机名部分和域名部分.例如，以下是有效的 FQDN:

Your hosts file does not include a valid FQDN, nor is localhost an FQDN. An FQDN must include a hostname part, as well as a domain name part. For example, the following is a valid FQDN:

host.server4-245.com

选择一个 FQDN 并将其包含在您正在使用的 IPv4 和 IPv6 地址的 /etc/hosts 文件中(在您的情况下，localhost 或 >127.0.0.1)，并在 httpd 配置中更改您的 ServerName 以匹配.

Choose an FQDN and include it both in your /etc/hosts file on both the IPv4 and IPv6 addresses you are using (in your case, localhost or 127.0.0.1), and change your ServerName in your httpd configuration to match.

/etc/hosts:

/etc/hosts:

127.0.0.1    localhost.localdomain localhost host.server4-245.com
::1          localhost.localdomain localhost host.server4-245.com

httpd.conf:

httpd.conf:

ServerName host.server4-245.com
