Hi all,
I have three servers: aps-1, aps-2, aps-3
On server aps-3 should start drbd with two resources ‘app’ and ‘mysql’, two
virtual IP’s, apache and mysql.
In case when aps-3 is down on server aps-1 should be started drbd with
resource of ‘app’, Virtual IP 10.11.4.1 and Apache.
In case when aps-3 is down on server aps-2 should be started drbd with
resource of ‘mysql’, Virtual IP 10.11.4.2 and Mysql.
APS-1 has real IP 10.11.4.4 apache2 2.2.9-10+lenny4
APS-2 has real IP 10.11.4.5 mysql-server 5.0.51a-24+lenny2,
APS-3 has real IP 10.11.4.3 mysql-server 5.0.51a-24+lenny2, apache2
2.2.9-10+lenny4
I have problem with starting Apache and Mysql.
Please explain me why I can start Apache and Mysql on any servers?
Thanks in advance,
