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?
