Server unreachable without www – Managing your servers can streamline the performance of your team by allowing them to complete complex tasks faster. Plus, it can enable them to detect problems early on before they get out of hand and compromise your business. As a result, the risk of experiencing operational setbacks is drastically lower.
But the only way to make the most of your server management is to perform it correctly. And to help you do so, this article will share nine tips on improving your server management and fix some problem about apache-2.2, domain, virtualhost, host, .
My server is unreachable without “www.” prefix, even when trying it with
The DNS entry looks like this:
$TTL 86400 @ IN SOA ns1.first-ns.de. postmaster.robot.first-ns.de. ( 2011010600 ; serial 14400 ; refresh 1800 ; retry 604800 ; expire 86400 ) ; minimum @ IN NS robotns3.second-ns.com. @ IN NS robotns2.second-ns.de. @ IN NS ns1.first-ns.de. @ IN A 188.8.131.52 localhost IN A 127.0.0.1 mail IN A 184.108.40.206 www IN A 220.127.116.11 ftp IN CNAME www imap IN CNAME www loopback IN CNAME localhost pop IN CNAME www relay IN CNAME www smtp IN CNAME www @
A DNS record of the same type for another domain on the same server is working with and without “www”.
And the VirualHost config looks like this:
<VirtualHost *:80> ServerName somewhere.com ServerAlias www.somewhere.com </VirtualHost>
An nslookup for www.somewhere.com and somewhere.com shows different IPs! The wrong IP is from a former version of the DNS record. Maybe some DNS servers are not up to date, but I wonder why they are up to date with the www. version.
Any idea what could be wrong?
In addition to incrementing the serial, as Chris S said in a comment, one small step often overlooked by those who don’t work with DNS routinely is telling the DNS server to reload the file.
As far as I know, you only need the A record for www to resolve.
Hostname IP Address 18.104.22.168 mail 22.214.171.124 www 126.96.36.199
Since almost all answers came in form of comments, I have to repeat a comment to answer the question.
The solution was: Increment the serial after adding the default record.
