Apache Problem with HA Load Balancer

Hi all,
i followed the tutorial:
High-Availability Load Balancer (With Failover and Session Support) With HAProxy/Heartbeat On Debian Lenny

Right now i get a Problem that apache is running no more (either on lb1 and lb2).
when i try to start i get:

Code:

(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
 failed!

Any ideas, or is that a normal behavior, and if, i also can´t get a website displayed with the virtual ip, although i can ping the ip

 

HAProxy is listening on port 80 already. You must run Apache on different servers, as shown in the tutorial.

 

ok, thanks for the reply.
i only had a few other services running on the 2 loadbalancers and would like it to be still availible, such as munin or nagios ....

any suggestion, that i can still use it, or do i have to transfer the setup to another server?

i can switch the apache in the lb to e.g. port 81 or 8080?

But what i want is that i can still access the vhosts of the lb on port 80.
so i tried to activate the second network interface eth1, which also works to log in by ssh.

but now, how to configure apache?

i tried:

NameVirtualHost 192.168.1.99:81
NameVirtualHost 192.168.1.98:80
Listen 81

where 192.168.1.99 is the ip of the lb.

But in order to get it run i need to tell apache to listen also on port 80, which doesn´t work
because og the known error:

(98)Address already in use: make_sock: could not bind to address [::]:80

 

You can either do this, or make Apache listen on another IP that is not in use by HAProxy (e.g. 192.168.1.98).

 

ok, thanks for the reply, i didn´t work it out, but think i could get it.
if you have any ports.conf advice - that would be very helpful.

another question, don´t know if it fits in here.

but did anyone try or have a tutorial für a system that either has the loadbalancer with apache and the mysql cluster running.

didnßt try it right now, because lack of computers.

but would like to test a setup:
2 loadbalancer
2 apache AND mysql server
1 mysql mgt server

for both are tutorials in running apache or mysql,
but is there a advice for loadbalancer setup for both, apache and mysql?
