[Linux-HA] [Heartbeat] my VIP doesn't work :(
Hi all, First I'm french so sorry in advance for my English... I have to use Heartbeat for High Availability between 2 Tomcat 5.5 servers under Linux RedHat 5.3. The first server is active, the other one is passive. The master is called servappli01, with IP address 186.20.100.40, the slave is called servappli02, with IP address 186.20.100.39. I configured a virtual IP 186.20.100.41. Each Tomcat is not launched when server is started, this is Heartbeat which starts Tomcat when it's running. My problem is : When heartbeat is started on the first server, then on the second server, the VIP is assigned to the 2 servers ! also, Tomcat is started on each server, and each node see the other node as dead ! Here is my configuration : ha.cf file (the same on each server) : logfile /var/log/ha-log debugfile /var/log/ha-debug logfacility none keepalive 2 warntime 6 deadtime 10 initdead 90 bcast eth0 node servappli01 servappli02 auto_failback yes respawn hacluster /usr/lib/heartbeat/ipfail apiauth ipfail gid=haclient uid=hacluster haresources file (the same on each server) : servappli01 IPaddr::186.20.100.41/24/eth0 tomcat Result of ifconfig command on the first server (servappli01) : eth0 Link encap:Ethernet HWaddr 00:1E:0B:BB:C2:38 inet adr:186.20.100.40 Bcast:186.20.100.255 Masque:255.255.255.0 adr inet6: fe80::21e:bff:febb:c238/64 Scope:Lien UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:14404996 errors:0 dropped:0 overruns:0 frame:0 TX packets:6580505 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 RX bytes:385833 (3.5 GiB) TX bytes:2694953468 (2.5 GiB) Interruption:177 Memoire:fa00-fa012100 eth0:0Link encap:Ethernet HWaddr 00:1E:0B:BB:C2:38 inet adr:186.20.100.41 Bcast:186.20.100.255 Masque:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interruption:177 Memoire:fa00-fa012100 Result of ifconfig command on the second server (servappli02) at the same time : eth0 Link encap:Ethernet HWaddr 00:1E:0B:77:C9:0C inet adr:186.20.100.39 Bcast:186.20.100.255 Masque:255.255.255.0 adr inet6: fe80::21e:bff:fe77:c90c/64 Scope:Lien UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:23815049 errors:0 dropped:0 overruns:0 frame:0 TX packets:17441845 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 RX bytes:2620027933 (2.4 GiB) TX bytes:3595896739 (3.3 GiB) Interruption:177 Memoire:fa00-fa012100 eth0:0Link encap:Ethernet HWaddr 00:1E:0B:77:C9:0C inet adr:186.20.100.41 Bcast:186.20.100.255 Masque:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interruption:177 Memoire:fa00-fa012100 Result of /usr/bin/cl_status listnodes command (on each server) : servappli02 servappli01 Result of /usr/bin/cl_status nodestatus servappli01 command on servappli01 : active Result of /usr/bin/cl_status nodestatus servappli02 command on servappli01 : dead Result of /usr/bin/cl_status nodestatus servappli01 command on servappli02 : dead Result of /usr/bin/cl_status nodestatus servappli02 command on servappli02 : active And of course, if I kill Tomcat on master server, there's no switch to the second server (a call to a webapp using the VIP doesn't work).

Bring up one node with the VIP running - leave the other node up but heartbeat down. an you ping the VIP from the node NOT running HA?
