Issues with DNS-server

Master DNS-server diagnostics

DNS server does not respond to request for domain zone

Make sure the DNS-server on the master server responds to requests for the domain zone:

dig <domain> @<IP address> ANY +short
View details

The response will look something like this: 

dig domain.name @1.1.1.1 ANY +short
mary.me. root.example.com. 2014041800 10800 3600 604800 86400
ns2.example.com.
ns1.example.com.
"v=spf1 ip4:1.1.1.1 a mx ~all"
10 mail.domain.name.
1.1.1.1

The following response indicates that the DNS-server is not running:

dig domain.nam @1.1.1.1 ANY +short
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.23.rc1.el6_5.1 <<>> domain.nam @1.1.1.1 ANY +short
;; global options: +cmd
;; connection timed out; no servers could be reached

An empty response indicates that the DNS-server doesn't have information about the domain. Perhaps, it could not upload the domain zone. Open the log for more details. 

Slave name server diagnostics

Checking connection with the DNS-server 

Try to connect to port 53 of the master server through telnet:

telnet <IP address of the master server> 53

If you cannot connect, check the Firewall settings on the master and slave servers.

Checking domain zone transfer from the master to the slave server

Execute the command:

dig <domain> @<IP-address> axfr
View details

The response should look like this:

dig domain.name @1.1.1.1 axfr
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.23.rc1.el6_5.1 <<>> domain.name @1.1.1.1 axfr

Issues with web-server

Web-server files

Apache configuration file

CentOS: /etc/httpd/conf/httpd.conf

Debian: /etc/apache2/apache2.conf

Nginx configuration

CentOS, Debian: /etc/nginx/nginx.conf

Issues with website statistics collection 

Statistics is not displayed to a user 

Statistics for a WWW-domain is stored in /var/www//data/www//webstat. Make sure that the files in this directory belongs to the user. 

Statistics displays only one unique visitor

This problem can occur if both Nginx and Apache are installed. To resolve the issue, install mod_rpaf for Apache.

Zero statistics

Check that the AWStats configuration file for the WWW-domain /etc/awstats/awstats..conf) has the parameter:

Awstats configuration file

LogFormat=1

Check the Apache configuration file for the WWW-domain /conf/vhosts// contains the forward — "combined":

Apache configuration file

CustomLog /var/www/httpd-logs/<WWW-домен>.access.log combined

How to exclude my IP from statistics

Add the following string into the configuration file /etc/awstats/awstats..conf.

Awstats configuration file

SkipHosts="<IP address>"
