[lvs-users] Ultramonkey heartbeat not starting ldirectord automatically
|
|
When heartbeat is started at bootup, it's not starting ldirectord.
Any idea why?
I do not have a stand by linux director. All the setup was done
following the instructions on
http://www.ultramonkey.org/3/topologies/hc-ha-lb-eg.html and
http://www.howtoforge.com/loadbalanced_mysql_cluster_debian.
My linux director files are set as follows and I have only 1 node:
vi /etc/ha.d/ha.cf
logfacility local0
bcast eth0
mcast eth0 225.0.0.1 694 1 0
auto_failback off
node a
#node loadb2
respawn hacluster /usr/lib/heartbeat/ipfail
apiauth ipfail gid=haclient uid=hacluster
vi /etc/ha.d/haresources
a \
ldirectord::ldirectord.cf \
LVSSyncDaemonSwap::master \
IPaddr2::192.168.0.240/24/eth0/192.168.0.255
vi /etc/ha.d/ldirectord.cf
# Global Directives
checktimeout=10
checkinterval=2
autoreload=no
logfile="local0"
quiescent=yes
virtual = 192.168.0.240:3306
service = mysql
real = 192.168.0.4:3306 gate
real = 192.168.0.5:3306 gate
checktype = negotiate
login = "ldirector"
passwd = "somepassword"
database = "ldirectordb"
request = "SELECT * FROM connectioncheck"
scheduler = wrr
On the main Linux Director, after starting heartbeat, ldirectord is
not automatically started by heartbeat. I get this:
[root@a me]# ps aux| grep heartbeat

Even with heartbeat stopped and ldirectord running, I can't connect to
mysql server.
