 Posted: Tue May 28, 2002 8:43 pm Post subject: Dynamic IP and Apache Virtual Hosts |
 |
|
Hello all,
I apologize if this has been posted already. I did a search and did not get any results.
Anyway, I needed a way to dynamically update my apache.conf file each time my IP changed. To accomplish this, I used the following steps:
- copy apache.conf to apache.conf.orig (or whatever naming convention you want)
- edit this apache.conf.orig and replace the hard coded IPs (such as in NameVirtualHost 111.222.333.444 and <VirtualHost 111.222.333.444>) with a variable name such as @MYIP@
- edit the /etc/conf.d/net file and add this line:
- edit the /etc/init.d/net.eth# for your dynamic adapter and add the following to the end of the start() function:
| Code: | if [ -n "$(myip)" ]
then
ebegin " Updating Apache Virtual Hosts"
/bin/sed "s/@MYIP@/$myip/g" < /etc/apache/conf/apache.conf.orig > /etc/apache/conf/apache.conf
eend 0
fi |
sed will go in and replace the @MYIP@ with the results of `hostname -i` from the net conf script.
- restart the net.eth# script and you should be all set!!
Assumptions:
- you call out the virtual hosts in the apache.conf file and not one of the files on the hosts directory. I havent tried it, but im sure you could do the same with the supplemental files

I tried | Code: | hostname -i
hostname --ip-address |
Both of them said "hostname: Unknown host"
Is there something I need to do with /etc/hosts to make hostname -i output my ipaddress? This would be much more efficient than the ifconfig -a | grep | cut madness that I've used in the past. |

| You may just have to set your hostname in /etc/hostname. I only have 127.0.0.1 localhost in my /etc/hosts. |

Hmmm, my /etc/hostname *has* my hostname in it.
Thanks for the suggestion anyway though. |

Rylan,
Well, after a few reboots, I had the same problem - it told me that hostname was unknown. I revapmed some of the code, and tried this:
-Edit /etc/init.d/apache in the start function to add the /bin/sed line:
| Code: | start() {
ebegin "Starting apache"
/bin/sed "s/@MYIP@/`hostname -i`/g" < /etc/apache/conf/apache.conf.orig > /etc/apache/conf/apache.conf
start-stop-daemon --quiet --start --startas /usr/sbin/apache \
--pidfile /var/run/apache.pid -- ${APACHE_OPTS}
eend $?
} |
Then set your apache.conf.orig as per the first post.
I think it was trying to execute the `hostname -i` before the network card came up and that is why it was giving us an error.
I tried rebooting my machine a few times as well as shutting the machine down and powering off the cable modem and it still works.
Let me know if it works for you. |

Ok, nice but how can i get the ppp0`s IP?
I have 2 IP, one for eth0 and one for ppp0 ( adsl connection )
The eth0`s IP is stable one and is local number like 10.200.1.1.
The real IP is the ppp0`s number.
Thanks
