It’s always a good idea to test your newly updated Apache
config file before restarting the service itself. This will help avoid downtime due to Apache
refusing to start due to misconfiguration. You can use apachectl
, httpd
or equivalent binaries as in the examples below;
Different platform might use different binary names such as apache
, apache2
or apache2ctl
httpd
# httpd -t AH00112: Warning: DocumentRoot [/var/www/mywebsite] does not exist AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1. Set the 'ServerName' directive globally to suppress this message Syntax OK
apachectl
# apachectl configtest AH00112: Warning: DocumentRoot [/var/www/mywebsite] does not exist AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1. Set the 'ServerName' directive globally to suppress this message Syntax OK
What happens is that the programs will try to parse the configuration files without implementing any of your changes. Once you get Syntax OK
at the end of the output and are satisfied with all the warnings (if any), you could confidently restart your Apache
service.

Follow these steps to begin tracking your AdSense based on URLs.
The programs normally used in Linux to show routing information is route and netstat. The following is an example of using both programs:
$ route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.64.64.64 * 255.255.255.255 UH 0 0 0 ppp0 default * 0.0.0.0 U 0 0 0 ppp0 $ netstat -r Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 10.64.64.64 * 255.255.255.255 UH 0 0 0 ppp0 default * 0.0.0.0 U 0 0 0 ppp0
It is advisable to include the -n options to both command for faster execution (by not resolving names, and produce slightly different result) as the following;
$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.64.64.64 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0 $ netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 10.64.64.64 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0
