Hi
I made a seconf test.
this time i use vmware, the three servers have debian etch , kernel
2.6.18 , they are in the same network and the client too.
server load-balancer: 192.168.0.3
server node1: 192.168.0.4
server node2: 192.168.0.5
I decided to do direct routing using the redirect option on iptables.
my virtual ip address will be 192.168.0.105
the service is mysql, i have a running cluster in wich 192.168.0.3 is
the manager, and 192.168.0.4 & 192.168.0.5 are the nodes.
So in the load-balancer(192.168.0.3) i set up ldirectord.cf as:
# Global Directives
checktimeout=10
checkinterval=2
autoreload=no
logfile="local0"
quiescent=yes
virtual = 192.168.0.105:3306
service = mysql
real = 192.168.0.4:3306 gate
real = 192.168.0.5:3306 gate
checktype = negotiate
login = "ldirector"
passwd = "*********"
database = "ldirectordb"
request = "SELECT * FROM connectioncheck"
scheduler = wrr
#>/etc/inid.d/ldirectord restart
in the node1(192.168.0.4) I did
#>iptables -t nat -A PREROUTING -p TCP -d 192.168.0.4 --dport 3306 -j
REDIRECT --to-port 3306
#>echo 1 >/proc/sys/net/ipv4/ip_forward
in the node2(192.168.0.5) i set
#>iptables -t nat -A PREROUTING -p TCP -d 192.168.0.5 --dport 3306 -j
REDIRECT --to-port 3306
#>echo 1 >/proc/sys/net/ipv4/ip_forward
but
ipvsadm -L always give:
#>ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=1048576)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 192.168.0.105:3306 wrr
-> 192.168.0.4:3306 Route 1 0 0
-> 192.168.0.5:3306 Route 1 0 0
imposible to connect:
error 2003 (HY000) Cannot connect to mysql server on 192.168.0.105
thanks in advance
