How to fix DNS problems in three easy steps

Troubleshooting DNS problems is a common challenge for web developers who just may have been exposed to challenges with the code and database. If you set up domains on a dedicated server or VPS for the first time and the challenges of the following will help.

1) The name servers are set up on a domain registrar. To see what nameservers are set to control a betterwhois.com domain (or any other service whois). For example, the domaindomain.info return nameservers DNS1 and dns2.stabletransit.net of Rackspace.

2) The correct name of the DNS server entries must be created. "One Voice", which is usually set for a host name, fields such as name and IP. An example is 174.143.155.XX subdomain.domain.info as the name and IP. IP is IP. You can trouble shoot using: zoneedit.com / lookup.html (If you use Linux you can also use the command nslookup).

Name ServerEntries are submitted with the name of the server. In the case of some web hosting companies as iweb.ca the name of the server is hosted on the same server as a Web server so that when an account is created in WHM DNS entries are set automatically. In the case of DNS Rackspace is housed separately so we have to manually set a DNS server entry in their name. To avoid the creation of many items for each subdomain, asabc.domain.info, def.lbclients.info and so on, a wildcard entry can be set to domain.info. Then each subdomain will point to the IP of choice (such as VPS).

To reiterate, when you type in your car subdomain.domain.info first to find the nameserver for domain.info, check the hostname of the nameserver IP from the server, and now the final step: as a folder on the server that will server-user point ofa?

3) In the case of a Linux Web server, the httpd.conf file (in / etc / httpd / conf) tells the web server on the server where the web site can be found. This file contains a series of "virtual hosts". It is called virtual because many hosts can be assigned to the same IP (so long ago this was not possible in Web server software, but each required a separate IP host name). Each virtual host directive will tell the web server where to uploadfile for a particular host name (server name or alias).

This virtual host directives are automatically created when you create an account in WHM, adding a parked or add-on domain. You can turn this mess shows the httpd.conf file via SSH (pico / etc / httpd / httpd.conf) and find the server name or alias.

Conclusion: If the file in a folder does not appear when you access your domain is very likely that there is a problem in one ofthe three phases. In this case, simply use the troubleshooting options as described above.
