Hello,
Thank you so much for your response. Basically what I am trying to do
is setup a mysql cluster via direct routing:
lb1
Heartbeat + ldirectord
IP Address: 192.168.2.101 eth0
lb2
Heartbeat + ldirectord
IP Address: 192.168.2.102 eth0
lb1 + lb2 Configureation Files
<ldirectord.cf>
#Global Directives
#checktimeout=10
checkinterval=2
autoreload=no
logfile="/var/log/ldirectord.log"
quiescent=yes
virtual = 192.168.2.100:3306
service = mysql
real = 192.168.2.104:3306 gate
real = 192.168.2.105:3306 gate
checktype = negotiate
login = "ldirector"
passwd = "Shlemon1"
database = "ldirectordb"
request = "SELECT * FROM connectioncheck"
scheduler = wrr
<ha.cf>
crm respawn
logfacility local0
bcast eth0
mcast eth0 225.0.0.1 694 1 0
auto_failback off
node lb1
node lb2
respawn hacluster /usr/local/heartbeat/lib/heartbeat/ipfail
apiauth ipfail gid=haclient uid=hacluster
keepalive 2
deadtime 11
debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility daemon
<haresources>
lb1 \
ldirectord::ldirectord.cf \
LVSSyncDaemonSwap::master \
IPaddr2::192.168.2.100/24/eth2/192.168.2.255
mysq1
IP Address 192.168.2.104 eth0
mysql2
IP Address 192.168.2.105 eth0
>What you should do is use several links, like
>bcast ethx
>mcast eth2 ...
>ucast eth3 ...
My questions are:
1) The machine only has one interface. Am I still able to set bcast,
mcast, and ucast to ethx, eth2, and eth3? I was following the
directions from
"http://www.howtoforge.com/loadbalanced_mysql_cluster_debian_p6";, and
they specified bcast and mcast on the same interface.
2) When I get this working smoothly, am I able to add another virtual
and service to ldirector? Say for eample pgsql?
3) Will the load balancers ever act as a bottleneck to the cluster,
and if so how do we handle such an issue.
In respect to the warnings, and errors that I am seeing in the log file:
